Cordless Drill Sprouts Wings And Takes Flight
» ‎ Hack a Day

Brushless motors and lithium batteries were a revolution for remote control aircraft. No longer would nitro engines rule the roost, as flying became far cheaper and more accessible almost overnight. The same technology has also found its way into power tools, leading to [Peter Sripol] deciding to build a powerdrill into a flying aircraft in this video, embedded below.

An unmodified DeWalt drill is the heart of the build, serving as the propulsion unit of the craft. A servo is used to actuate the drill’s trigger to serve as the throttle. As power drills are geared down significantly compared to a typical hobby brushless motor, it was necessary to use a much larger prop than would be usual. This was custom machined out of wood with the help of [William Osman], and despite some mishaps, came out (mostly) in one piece. The airframe consists of foam wings with poplar spars, and an aluminium extrusion serves as the tail boom. A few 3D printed parts then tie everything together.

Despite the weight of the drill, the hacked-together craft is able to fly quite easily. The large wings and propeller help to make up for the shortcomings of the powertrain. Unfortunately, there wasn’t quite enough surplus lift to carry a payload of smartphones to capture in-flight footage, but overall the project could be considered a resounding success.

We’ve seen [Peter]’s work before, too – sometimes even putting himself in the pilots seat! Video after the break.

A DIY Bench-Sized Milling Machine
» ‎ Hack a Day

Hanging around the machining community online, you’d be more than familiar with clapped out Bridgeport mills, which are practically a meme at this point. But mills come in all shapes and sizes, from the stout old iron from the days of yore, to smaller, compact builds. [Honus] decided to build the latter, and shared the details of the project.

The aim of [Honus’s] build is to create a small benchtop mill, capable of handling the smaller tasks. The frame of the mill is built out of 80/20 extrusion, with plenty of aluminium plate to go along with it. Igus linear slides handle the X, Y and Z axes. An old brushed Makita drill motor serves as the spindle drive, controlled by an old R/C speed controller hooked up to an Arduino. [Honus] then fabbed up various bits and pieces as neccessary to bring it all together.

The mill is neat and tidy, and looks to do a good job machining aluminium. We imagine it should prove highly useful in [Honus’s] workshop. If you’re contemplating getting yourself some desk-sized tools, perhaps consider an engraver as well! Video after the break.

Minature Table Saw Gets The Teeny Jobs Done
» ‎ Hack a Day

Table saws are highly useful tools, but tend to take up a lot of space. They’re usually designed to handle the bigger jobs in a workshop. It doesn’t have to be that way, however, as [KJDOT] demonstrates with a miniature table saw.

It’s a saw that relies on a simple build. The frame is made of plywood, and can be built with just a drill and a hand saw. A brushed motor is used to run the saw, using an off-the-shelf PWM controller and a 24V power supply. A handful of bearings and standard brackets are then used to put it all together, and there’s even a handy adjustable fence to boot. With a 60mm blade fitted, the saw is ready to go.

It’s a build that would be great for anyone regularly working with wood or plastics on the smaller scale. If you like building dollhouses, this could be the tool for you. You might also find the table nibbler to be an enticing proposition. Video after the break.

How Do Those Component Testers Work?
» ‎ Hack a Day

Most people have at least seen those cheap component testers you can buy on the Chinese websites for $10 or so. If you haven’t seen them before, they usually have some kind of multi pin socket. You put a component in the socket and it will identify — with a push of a button — what the part is, which pin is which, and the value of the part. For example, you can insert a resistor, a capacitor, an inductor, a diode, or a transistor and get a readout of which pin is which. It seems like magic, but [Andreas Spiess] did the research on how it all works and summed up his findings in a recent video.

[Andreas] even quotes our earlier post on the topic and, as we did, dug into the original developers of the device which has been cloned over and over by Chinese sellers. Although there have been some divergence with all the different versions, the basic idea is the same. An AVR CPU uses some analog and digital trickery to make a lot of different measurements.

There are quite a few coding tricks you can learn by examining how the testers can do the job with very few external components. It also helps to go to the original project. Just be careful. Your $7 tester from eBay might not be able to work with the original code — some makers do simple modifications for different displays or other reasons.

We’ve seen these hacked to do other things, although maybe nothing as useful as the original. More fun perhaps, but not as useful.

A Crane Fit For Any Workshop
» ‎ Hack a Day

Sometimes we will encounter items in our workshops that are a little bigger than we bargained for. An engine block, an anvil, or a particularly substantial machine tool. Lifting these things may be possible, but doing so risks injury, perhaps a hernia or worse. For these moments a particularly well-appointed workshop will include a small crane, and [Workshop from scratch] has posted a video that we’ve placed below the break showing the construction of a particularly nice model.

The fabrication of a crane is not in itself a difficult task, in that most metalwork-minded readers could probably make one. What’s appealing about this video is the sense of gratification at watching metalwork being done well, and that while he does use a bandsaw and a drill press there’s not a lot in the video that couldn’t be done with more basic tools. The result is a handsome item that is probably better than many commercial offerings, though the gut feeling here is that the pivot points would have been better made with a sleeve and pin rather than a threaded bolt. The lifting effort comes from an off-the-shelf hydraulic ram.

Cranes feature here surprisingly rarely, but at least we’ve brought you a balcony crane.

Modular fixture plates perfect for small production runs
» ‎ Hack a Day

If you’ve ever done any small production runs of anything that needs a bit of assembly, you know that jigs and fixtures are a huge time saver. However, these usually need to be mounted, which means you end up drilling holes in your workbench or making one-off mounting plates. [Jim Smith] is no stranger to this problem, and created the Pact Plate, an affordable modular fixture plate and is running a Kickstarter campaign to get it produced.

Each plate 150 mm × 150 mm in size with a 25 × 25 mm grid of holes with M4 threaded inserts. This allows quickly and easily mounted to and removed from the plate without the need to drill additional holes. Plates can be bolted together to form larger plates. The demo video shows him using a variety of 3D printed jigs, toggle clamps, PCB and part holders (available for download) and even a robot to quickly set up small assembly stations. This could also save a lot of time during the prototyping and development phases to hold parts in place.

[Jim]’s prototypes are all 3D printed, but want’s to get tooling made to produce the plates using injection moulding. He doesn’t say what material he intends to use, but it’s likely some type of fibre reinforced plastic. He claims the rigidity is close to that of die-cast aluminium. One addition we would like to see is some plugs for the unused hole to prevent small components from falling into them.

While fixture plates are nothing new, they are usually way more expensive than the $20 Pact Plate. There are always risks with crowd funding campaigns but it looks like [Jim] has all his bases covered pretty well. The prototyping work is done so only tooling needs to be made and samples tested, which should be fairly straight forward for a design like this.

We’ve featured some of [Jim]’s projects before, including a 3D printed kayak and the massive 3D printer he used to print it.

Bend some Bars with a Flywheel
» ‎ Hack a Day

The ability to look at a pile of trash, and see the for treasure is a skill we hold in high regard around here. [Meanwhile in the Garage] apparently has this skill in spades and built himself a metal bar bending machine using an old flywheel and starter pinion gear.

To bend metal using muscle power alone requires some sort of mechanical advantage. Usually this involves a bending tool with a long lever, but [Meanwhile in the Garage] decided to make use of the large gear ratio between a car’s starter motor and the flywheel it drives. This does away with the need for a long lever and allows bending to almost 270° with a larger radius. Lathe and milling work features quite prominently, including to make the bend formers, drive shaft and bushings and to modify the flywheel to include a clamp. The belt sander that is used to finish a number of the parts is also his creation. While the machine tools definitely helped, a large amount of creativity and thinking outside the box made this project possible and worth the watch.

We’ve featured a number of scrap-built tools including a milling machine, sheet metal hole punch and a hydraulic bench vice. Keep them coming!

Helicopter Chain Saw
» ‎ Hack a Day

Among the most dangerous jobs in the United States are timberjack and aircraft pilot. Combining the two wouldn’t sound like a recipe for success, but in fact it makes the job of trimming trees near pipelines and power lines much safer. That’s what this helicopter-suspended chainsaw does. And it definitely doesn’t look safe, either, but here we are.

The saw is equipped with ten two-foot diameter saws and is powered by a 28 horsepower engine which is separate from the helicopter itself. The pilot suspends the saw under the helicopter and travels along the trees in order to make quick work of tree branches that might be growing into rights-of-way. It’s a much safer (and faster) alternative that sending out bucket trucks or climbers to take care of the trees one-by-one.

Tree trimming is an important part of the maintenance of power lines especially which might get overlooked by the more “glamarous” engineering aspects of the power grid. In fact, poor maintentance of vegitation led to one of the largest blackouts in recent history and is a contributing factor in a large number of smaller power outages. We can’t argue with the sentiment around the saw, either.

The Miniware TS100 As A USB-C Soldering Iron
» ‎ Hack a Day

Many readers will be familiar with the Miniware TS100 soldering iron, a lightweight temperature-controlled iron that is giving significantly more expensive soldering tools a run for their money. There is another model in the range, the TS80, which though it uses different tips than its sibling has the main distinguishing feature of USB-C power rather than a DC barrel jack. A cadre of users still prefer the TS100 for this reason, as an iron that can run from almost any low voltage DC power source. Any except USB-C, that is, an omission that [thinkl33t] has rectified with a USB-C adapter for the older model.

To achieve this, he’s used a readily-available ZYPDS USB-to-DC module and attached it to a barrel jack. For now, it’s simply held on by solder with a bit of heat-shrink over the top. [Thinkl33t] observes that this may not prove to be strong enough and he’ll eventually have to put it on a bit of cable. It’s a simple enough hack, but it serves as a quick introduction to these parts which perform the necessary USB-C magic to deliver a DC supply, as well as to highlight the relative scarcity of higher-power USB supplies.

At the moment there’s an inevitable move to USB-C All The Things, but it’s a trend that it seems many manufacturers of power sources have yet to catch up with. When a typical TS-80 owner finds their shiny new USB-C battery bank is, in reality, an older 5V USB bank with a USB-C connector fitted, it’s no wonder that their friends prefer the TS100. We hope that coming years will see a greater range of USB-C power options, but until then we like the versatility of the barrel jack on the TS100. Especially now that it can so readily be made to take USB-C power.

We reviewed the TS100 back in 2017, and two years of using it since then have not changed our opinion of it.

Thanks to the several tipsters including [thinkl33t] himself who sent us this.

Tiny Woodshop Is Packed With Space-Saving Hacks
» ‎ Hack a Day

Fair warning: once you’ve watched [Stephen]’s tiny workshop tour, you will officially be out of excuses for why you need to expand your workshop. And, once you see his storage and organization hacks, you’ll be shamed into replicating some in whatever space you call home.

[Stephen]’s woodshop is a cozy 6′ x 8′ (1.8 m x 2.4 m) garden shed. The front wall is almost entirely occupied by the door and a window, reducing the amount of wall space available but providing ample natural light and keeping the small space from inducing claustrophobia. Absolutely every square inch of the remaining space is optimized and organized. [Stephen] wisely eschews bulky cabinets in favor of hanging tool racks, all mounted flexibly to the wall on French cleats. Everything has a place, and since every hand tool is literally within arm’s reach, it stays stored until it’s needed and goes right back when it’s done. The shop boasts way more than hand tools, though; a lathe, drill press, thickness planer, sander, air compressor, scroll saw, band saw, and even a table saw all fit in there. There’s even dust collection courtesy of “The Beast”, [Stephen]’s DIY dust extractor.

No matter whether you work in wood, metal, or silicon, we could all learn some lessons from [Stephen]’s shop. It’s a model of efficiency and organization, and while he’s not likely to build a full-size [Queen Anne] dresser in there, it’s clear from his blog that he gets a lot done with it. Too bad we missed this one the last time we did a roundup of tiny shops.

Modified Tombstone Welder Contains a Host of Hacks
» ‎ Hack a Day

State-of-the-art welding machines aren’t cheap, and for good reason: pushing around that much current in a controlled way and doing it over an entire workday takes some heavy-duty parts. There are bargains to be found, though, especially in the most basic of machines: AC stick welders. The familiar and aptly named “tombstone” welders can do the business, and they’re a great tool to learn how to lay a bead.

Tombstones are not without their drawbacks, though, and while others might buy a different welder when bumping up against those limits, [Greg Hildstrom] decided to hack his AC stick welder into an AC/DC welder with TIG. He details the panoply of mods he made to the welder, from a new 50 A cordset made from three extension cords where all three 12 gauge wires in each cord are connected together to make much larger effective conductors, to adding rectifiers and a choke made from the frame of a microwave oven transformer to produce DC output at the full 225 A rating. By the end of the project the tombstone was chock full of hacks, including a homemade foot pedal for voltage control, new industry-standard connectors for everything, and with the help of a vintage Lincoln “Hi-Freq” controller, support for TIG, or tungsten inert gas welding. His blog post shows some of the many test beads he’s put down with the machine, and the video playlist linked below shows highlights of the build.

This isn’t [Greg]’s first foray into the world of hot metal. A few years back we covered his electric arc furnace build, powered by another, more capable welder.

Thanks to [James Analytic] for the tip.

Digital Oscilloscope Does Its Best Analog Impression
» ‎ Hack a Day

Do you ever find yourself yearning for the days before digital storage oscilloscopes (DSOs)? Where even the basic scopes commanded four figures, and came in a bench-dominating form factor? No, of course you don’t. The DSO is a wonder of modern technology: for a couple hundred bucks you can have capabilities that previously would have been outside the reach of hobbyists, all in a package that’s small enough to fit on even the most cramped workbenches.

Which is why the good folks of the EEVblog forums are so confused about the OWON AS101, a modern digital oscilloscope that’s designed to look and operate like the analog CRT monsters of old. Despite the 3.7 inch LCD, users are treated to the classic analog scope look, and the switches and knobs on the front should trigger a wave of nostalgia for hackers of a certain age.

But this isn’t just some “retro” look-alike, OWON is committed to delivering on that analog experience by taking away all those modern digital features we’ve become so dependant on. This single-channel scope can’t save data to USB, doesn’t have any sort of protocol decoding capabilities, and forget about automatic…well, anything. It’s even limited to 20 MHz, just like the old-school CRT scopes that you pick up for a song at any swap meet. All for the low, low, price of $150 USD from the usual importers.

In the EEVblog thread, the best idea anyone can come up with is that the OWON AS101 is designed for educational markets in developing countries, where outdated equipment is so common that there may actually be a need for faux-analog oscilloscopes to match what’s already in use. These new-manufactured “analog” trainers can be used to get students ready to a professional life of using antiquated technology. It’s hard to believe, but sometimes we can forget how fortunate many of us are to have easy access to cheap tools and equipment.

Even still, when you can get a pocket-sized 10 MHz DSO for around $50, it’s difficult to imagine how this analog-digital hybrid could possibly attract any takers at 3x times the price. If any of our readers would care to shed some light on this unusual piece of gear, we’d love to hear it.

[Thanks to David for the tip.]

Cheap Stereo Microscope Helps With SMD
» ‎ Hack a Day

Soldering is best done under magnification. Parts become ever smaller and eyes get weaker, so even if you don’t need magnification now, you will. [Makzumi] didn’t want to shell out $400 or more for a good microscope so he hacked one from some cheap binoculars from the toy section on Amazon.

A lot of magnifiers aren’t really good for soldering because the distance between the work and the lens isn’t very large. The hacked ‘scope has about 4 inches of working distance, which is plenty of room to stick some solder and a hot iron under there. The resulting magnification is about 12 or 15X and he claims that the cell phone pictures he’s included aren’t as good as really looking through the eyepieces yourself.

The project requires two toy binoculars. The ones linked are 26mm 2.5X foldable ones that cost under $5 each. One of them will get ripped apart for lenses. The other will form the main eyepieces of the scope. You’ll also need a little PVC pipe, some epoxy, and some wood to make a stand.

Since the modified binoculars will be looking at things very close, you have to cut into them to make them look almost cross-eyed. It appears the whole thing might cost $20 and it appears to work well. We’ve looked at other solutions like the Dino-Lite. There are also many cheap USB microscopes around.

You Didn’t See Graphite Around This Geiger Counter
» ‎ Hack a Day

Even if you don’t work in a nuclear power plant, you might still want to use a Geiger counter simply out of curiosity. It turns out that there are a lot of things around which emit ionizing radiation naturally, for example granite, the sun, or bananas. If you’ve ever wondered about any of these objects, or just the space you live in, it turns out that putting together a simple Geiger counter is pretty straightforward as [Alex] shows us.

The core of the Geiger counter is the tube that detects the radiation. That’s not something you’ll be able to make on your own (probably) but once you have it the rest of the build comes together quickly. A few circuit boards to provide the tube with the high voltage it needs, a power source, and a 3D printed case make this Geiger counter look like it was ordered from a Fluke catalog.

The project isn’t quite finished ([Alex] is still waiting on a BNC connector to arrive) but seems to work great and isn’t too complicated to put together, as far as Geiger counters go. He did use a lathe for some parts which not everyone will have on hand, but a quick trip to a makerspace or machinist will get you that part too. We’ve seen some other parts bin Geiger counters too, so there’s always a way around things like this.

Scrapyard Milling Machine Gets Work Done on a Budget
» ‎ Hack a Day

Which to buy first, a lathe or a mill? It’s a tough question for the aspiring home machinist with limited funds to spend on machine tools, but of course the correct answer is a lathe. With a lathe, we are told, all other machine tools can be built, including a milling machine. Granted that might be a slight exaggeration, but [Maximum DIY] was still able to use his budget-blowing lathe to make a decent milling machine mostly from scrap.

Details are a bit sparse in the forum post, but there’s enough there and in the video after the break to be mightily impressed with the build. Unlike many DIY mills that are basically modified drill presses, [Maximum DIY] started with things like a scrapped bench grinder pedestal and surplus steel tubing. The spindle motor is from a paint sprayer and the Z-axis power feed is a treadmill incline motor. The compound table was a little too hard to make, so the purchased table was fitted with windshield wiper motor power feeds.

Therein lies perhaps the most clever hack in this build: the use of a plain old deep 19mm socket as a clutch for the power feeds. The 12-point socket slides on the square shaft of the wiper motor to engage the drive screw for the compound table – simple and bulletproof.

To be sure, the finished mill is far from perfect. It looks like it needs more mass to quell vibration, and those open drive pulleys are a little nerve wracking. But it seems to work well, and really, any mill is better than no mill. Of course, if you’re flush with cash and want to buy a mill instead of making one, this buyer’s guide should help.

Old Chainsaw Repurposed For Kitchen Use
» ‎ Hack a Day

There are many ways to keep critical appliances running during a power outage. Maybe a UPS for a computer, a set of solar panels to charge your phone, or even a generator to keep your refrigerator or air conditioning working. This modification to a standard blender will also let you ride through a power outage while still being able to make delicious beverages. It runs on gasoline.

The build uses an old chainsaw to power the blades of the blender. [Bob] was able to design and build an entirely new drivetrain to get this device to work, starting by removing the chainsaw chain and bar and attaching a sprocket to the main shaft of the motor. A chain connects it to a custom-made bracket holding part of an angle grinder, which supports the blender jar. Add in a chain guard for safety and you’ll have a blender with slightly more power than the average kitchen appliance.

The video of the build is worth watching, even if your boring, electric-powered blender suits your needs already. The shop that [Bob] works in has about every tool we could dream of, including welders, 3D printers, band saws, and even a CNC plasma cutter. It reminds us of [This Old Tony]’s shop.

Control The Suck With This Manual Vacuum Pick-And-Place Tool
» ‎ Hack a Day

The tapes that surface-mount devices come in may be optimized for automated pick and place, but woe betide those who try to dig components out manually. No matter what size package, the well on the tape seems to be just a wee bit too small to allow tweezers to grip it, so you end up picking the thing up edgewise or worse, pinching too tight and launching the tiny thing into The Void. We hope you ordered extra.

Such circumstances are why vacuum handlers were invented, but useful as they are for picking and placing SMDs, they aren’t perfect. [Steve Gardener]’s sub-optimal experience with such tools led him to build this custom vacuum pick-and-place tool. It’s based on an off-the-shelf Weller unit, of which only the handpiece remains. A bigger, more powerful vacuum pump is joined in a custom enclosure by a PCB with a PIC18F13K22 microcontroller, a power supply, a solenoid to control the vacuum, and a relay to switch the pump. A footswitch starts the pump and closes the vacuum vent; letting off the pedal opens the vent to drop the part, while the pump keeps running for a variable time. This lets him rapidly work through a series of parts without having to build vacuum back up between picks. The video below shows the build and the tool in action.

We love the idea of this tool, and the polished look is pretty slick too. If manual pick-and-place isn’t for you, though, maybe converting a 3D-printer into an automated PnP is something to check out.

Print Your Own Heat Shrink Labels for Factory-Chic Wire Naming
» ‎ Hack a Day

Heat shrink tubing is great for insulating wires. Labeling wires in a bundle is always useful, too. [Voltlog] has a cheap Brother label printer and discovered he can buy knock off label cassettes for a lot less from China. However, he also found something else: cassettes with heat shrink tubing in them made for the same kind of printer. Could he use the heat shrink cassettes to make neat wire labels? In his first video the answer was sort of, but not really. However, he later had a breakthrough and made a second video explaining how to do it. You can see both videos, below.

At first, the printer didn’t even want to recognize the cassette. It seems like Brother doesn’t want you using exotic tapes with cheap printers. No worry, this isn’t sophisticated DRM, just a sense hole that you need to cover with tape. This discovery was made using the extremely scientific trick of covering all the holes that were not on a regular cassette.

With the holes covered up, the printer worked, but the print came out mirrored. To understand why, you have to understand how the normal labels work. In the cassette, the label material has no paper backing which is separate in a different part of the cartridge. The printer marks the backside of the see-through label and then bonds the paper backing to it as it exits the printer. This makes sense because it puts the markings under the tape where they are relatively safe from moisture or physical abrasion.

However, with heat shrink, it isn’t transparent and there’s no backing material. So the reverse print doesn’t really help you. It turns out the cheap printer can do non-mirrored printing, but to make that work, one of the holes in the special cassette needed to stay open. Once the proper holes were covered and uncovered, everything worked great.

Heat shrink is probably more high tech than you’d think. Did you know you can get it with adhesive inside it, too?

Shop-Made Tools Turn Cheap Steel into Telescoping Tubes
» ‎ Hack a Day

Beginning metalworkers are often surprised at just how cheap steel can be. It’s a commodity made by the gigaton, and there are always plenty of extra pieces and scraps left over from big projects that are available for pennies a pound. But what you’ve got is often not what you need, especially when it’s steel tubing with welded seams that prevents one tube from fitting inside another.

[Jason Marburger] from Fireball Tool has some great tips for cleaning interior welds in steel tubing. The first part of the video below details manual methods for cleaning off seam welds, including chiseling, sanding with a narrow belt sander, and grinding them down with a die grinder. Those all work well, but only for short lengths of tubing. Longer tubes need special treatment, which is where the clever tools [Jason] designed come in handy.

By attaching a chunk of high-speed steel to a slug made from the next size tube down and driving it through the tube to be cleaned with a hefty piece of threaded rod, he basically created ain internal shaper to shave the weld down. It works like a charm, as does the tool he made for round tubing by laying a bead of hard facing welding rod around the edge of a mild steel slug. Driving this tool into the seamed round tubing with a shop press cleaned up the weld nicely too.

Hats off to [Jason] for coming up with a couple of great shop tips to keep in mind. We’ve seen similar expedient tools for metalworking lately, like this homemade die-punching tool and a linear track to keep your plasma cutter in line.

NanoVNA is a $50 Vector Network Analyzer
» ‎ Hack a Day

There was a time when oscilloscopes were big and expensive. Now you can get scopes of various sizes and capabilities on nearly any budget. Vector network analyzers — VNAs — haven’t had quite the same proliferation, but NanoVNA may change that. [IMSAI Guy] bought one for about $50 and made a series of videos about it. Spoiler alert: he likes it. You can see one of the several videos he’s posted, below.

NanoVNA is tiny but sweeps from 50 kHz to 900 MHz and has a touch screen. The device uses a rechargeable battery if you need to haul it up to an antenna tower, for example. Just as a quick test, you can see early in the video the analysis of a rubber duck antenna. The device shows return loss as a plot and you can use a cursor to precisely measure the values. It also shows a Smith chart of the reactance.

If you don’t like the touch screen, you can also control the device via USB. You need software from Google Drive and you can also get the manuals from there. In addition, there are additional firmware files available so you can reflash the instrument. For example, you can limit the top frequency to 300 MHz or select a larger font.

You might wonder why you’d limit the frequency to 300MHz. According to the manual, the instrument has better performance under 300 MHz. There is also provisions for calibrating the device in the field.

For $50 it is pretty impressive. [IMSAI] guy also did a video about its accuracy, checking its output with a scope and frequency counter.

We’ve looked at other cheap VNAs although this one has an interesting range of frequencies compared to some we’ve seen before. We also put the Analog Discovery 2’s VNA through its paces. It costs a good bit more, but also does other things, but the VNA tops out at 10 MHz.

Stepper-Controlled Chop Saw Automates a Tedious Job
» ‎ Hack a Day

We’re not going to question why [Absorber Of Light] needs to cut a bazillion little fragments of aluminum stock. We assume his reasoning is sound, so all we’re interested in is the automated chop saw he built to make the job less tedious, and potentially less finger-choppy.

There are probably many ways to go about this job, but [Absorber] leaves few clues as to why he chose this particular setup. Whatever the reason, the build looks like fun, with a long, stepper-driven threaded rod pushing a follower down a track to a standard chop saw. The aluminum stock rides in the track and gets pushed out a set amount before being lopped off cleanly as the running saw is lowered by a linear actuator. The cycle then repeats until the stock is gone.

An Arduino controls the stock-advance stepper in the usual way, but the control method for the linear actuator is somewhat unconventional. A second stepper motor has two cams offset by 180° on the shaft. The cams actuate four microswitches which are set up in an H-bridge configuration. The stepper swivels back and forth to run the linear actuator first in one direction then the other, with a neutral position in between. It’s an interesting approach using mechanical rather than the typical optical isolation. Check it out in action in the video below.

We’ll admit to some curiosity as to the use of the coupons this rig produces, so maybe we’ll get lucky with some details from [Absorber Of Light] in the comment section. After all, we knew exactly what the brass tubes being cut by the similar “Auto Mega Cut-O-Matic” were being used for.

Pop-Up Outlet Helps Make the Most of a Tiny Shop
» ‎ Hack a Day

You’ve got to admire the steps some people take to squeeze a shop into a small space. Finding ways to pack in ever more tools and to work on bigger and bigger projects become ends to themselves for some, and the neat little tricks they find to do so can be really instructive.

Take this workbench pop-up outlet strip for example. The shop that [Woodshop Junkies] occupies appears to be a single-car garage, on the smallish size in the first place, that is almost entirely filled with a multipurpose workbench. It provides tons of storage underneath and a massive work surface on top, but working with small power tools means stretching extension cords across the already limited floor space and creating a tripping hazard. So he claimed a little space on the benchtop for a clever trap door concealing a small tray holding an outlet strip.

The tray rides on short drawer glides and, thanks to a small pneumatic spring, pops up when the door is unlatched. There was a little trouble with some slop in the glides causing the tray to jam, but that was taken care of with a simple roller bearing. The video below shows its construction and how it stays entirely out of the way until needed.

As cool as this build is, it’s just icing on the small shop cake when compared to the workbench. [Woodshop Junkies] has a complete playlist covering the build which is worth watching. And you might want to refer to our tiny shop roundup for more tips on getting a lot done in a little space.

Thanks to [Itay Ramot] for the tip.

Field Expedient Soldering Iron Will Do In A Pinch
» ‎ Hack a Day

If you think [Dubious Engineering]’s moniker is just a name, have a look at the pretty terrible soldering iron hacked out of a lighter in the video below. No one is suggesting this is a good idea but in an emergency, maybe it would come in handy. We liked the use of a chopstick and the formation of a heat exchanger with the copper wire coil. It was a mild disappointment that you had to drill out the chopstick, but we think you could have figured out a different method with a little thought.

The use of duct tape, of course, lends it instant hacker credibility. We suppose this might be useful not just after the robot uprising, but if you had to make a few quick solder joints far away from power and you don’t have a battery-operated iron.

The helping hands didn’t seem very helpful for this. We have a bad habit of just holding the wires with a solder spool against the bench. We’ve also used this 3D printed jig, but you do have to be careful not to drop hot solder on the plastic or put some foil in the gap to catch drips.

If you really wanted to use this in an emergency, a candle might be more useful than a lighter. Of course, battery irons aren’t as uncommon as they once were, so maybe just get one of those. There is also a crop of irons that you can power from USB to varying degrees of success.

Punch Those Hole-Drilling Blues Away with a Homebrew Punching Tool
» ‎ Hack a Day

Four times the holes, four times the trouble. With the fate of repetitive motion injury looming due to the need to drill 1,200 holes, [bitluni] took matters into his own hands and built this nifty DIY hole punch for light-gauge sheet metal.

A little backstory will probably help understand why [bitluni] needs so many holes. Back in May, he built a ping pong ball LED video wall for Maker Faire Berlin. That had 300 LEDs and came out great, but at the cost of manually drilling 300 holes in sheet steel with a hand drill. Looking to expand his wall of balls to four times the original size, [bitluni] chose to spend a few days building a punch to make the job more appealing. The business end, with solid bar stock nested inside pieces of tubing, is a great example of how much you can get done without a lathe. The tool is quite complex, with a spring-loaded pilot to help guide the punching operation. When that proved impractical, [bitluni] changed the tool design and added an internal LED to project crosshairs from inside the tool.

The tool itself is mounted into a sturdy welded steel frame that allows him to cover the whole aluminum sheet that will form the panel of his LED wall. It’s pretty impressive metalwork, especially considering this isn’t exactly in his wheelhouse. And best of all, it works – nice, clean holes with no deformation, and it’s fast, too. We’re looking forward to seeing the mega-LED wall when it’s done.

Hydraulic Bench Vise a Masterpiece of Scrap Metal and Angle Grinding
» ‎ Hack a Day

For most of us, a vise is the sort of thing you clamp onto the edge of a workbench and crank down by hand. It might even be made of plastic, depending on the kind of work you find yourself doing with it. But it’s safe to say that [WorkshopFromScratch] won’t be soldering any PCBs in the jaws of this nearly 100 lb hydraulic vise that he built from, well… scratch.

In the video after the break, he takes an array of scrap metal including what appears to be a chunk of racking from the Home Depot and a rusted plate that looks like it could be peeled off the hull of a sunken ship, and turns it into a monsterous vise with five tons of clamping force. Outside of a handful of bolts, a couple of gas struts, and the hydraulic bottle jack that that provides the muscle, everything is hand-cut and welded together. No fancy machining here; if you’ve got an angle grinder, a welder, and of course the aforementioned stock of scrap metal, you’ve got the makings of your own mega vise.

The piece of racking is cut down the center to form the base of the vise, but most everything else is formed from individual shapes cut out of the plate and welded together. Considering the piecemeal construction methods, the final result looks very professional. The trick is to grind all the surfaces, including the welds, down until everything looks consistent. Then follow that with a coat of primer and then your finish color.

While the whole build is very impressive, our favorite part has to be the hand-cut cross hatching on the jaws. With the workpiece in one hand and angle grinder in the other, he cuts the pattern out with an accuracy that almost looks mechanical. If we didn’t know better, we might think [WorkshopFromScratch] was some kind of metalworking android from the future.

Being able to work with metal is a fantastic skill to have, and we’re always impressed to see what folks can produce with a welder and some scrapyard finds. Especially when they build tools and equipment that can be put to practical use.

A Drop-In Controller Replacement For Commercial Reflow Ovens
» ‎ Hack a Day

If you need a reflow oven, you can very easily head down to Walmart or Target and pick up a toaster oven for fifteen bucks or so. Even without any control electronics, a bone-stock toaster oven works well enough for reflow soldering, but if you want to do it right you’ll also want to add a themocouple, a microcontroller, and maybe a fancy display. That’s option one.

If you value your time more than your money, you’ll probably just plonk down a few hundred bucks for a T-962A reflow oven, the standard infrared oven that’s meant for reflowing solder. It’s a good oven, but as with all bargain basement tools from China, the user interface isn’t great. [PhillyFlyers] is working on a drop-in controller for what is probably the most popular reflow oven on the planet, and this thing looks good.

This is a controller for the T-962A oven that includes all the connectors as the stock control board. We’ve seen a few of these projects to improve cheap tools, from 3D printer controllers to a replacement board for the ubiquitous K40 laser cutter. Now the most popular reflow oven is getting the same treatment.

The specs for this replacement board include a five-inch, 800 x 480 display, powered by an STM32H7 microcontroller. All of the usual functionality of the oven is retained, but it adds the ability to hand-draw reflow profiles, save reflow profiles to an SD card, and support for four K-type thermocouples. Basically, it’s what you would expect from an upgraded version of the T-962 oven.

Most importantly, this is a direct drop-in replacement for the stock electronics. Grab one of these boards, and all you have to do for installation is break out a screwdriver. It makes a great tool even better, which is exactly what this very popular reflow oven needs.

A Complete Desktop PCB Etching Station
» ‎ Hack a Day

Right now you can get a custom circuit board delivered to your door in about a week for just a few dollars. There’s little reason to make your own circuit boards at home anymore, but when you need a board now, you want to have that capability. [Tuval Ben Dosa] designed a complete PCB etching station that is the perfect tool for making printed circuit boards at home. It’s got everything you need for the perfect etch, and with this setup you can make a board in hours instead of waiting for days.

The chemistry for any etching setup is important, and in recent years the entire community has moved from ferric chloride to copper chloride for a very good reason: you can recharge copper chloride etchant by bubbling oxygen (or air) through it, whereas ferric chloride is a one-use etchant.

The mechanical part of this build consists of an airtight glass food container sitting on top of a PCB heating element not unlike the heated bed of a 3D printer. Along with that is an I2C temperature sensor encased in a silicone tube, a stir bar, diaphram pump, and a few pumps to blow air into the etchant and pump out the chlorine gas generated. This is controlled by a small microcontroller with a UI consisting of just an encoder and OLED display.

If you’re looking for builds that will etch copper and brass at home, this has been something that has been done before. The Etchinator is a fantastic build capable of making everything from printmaking plates to printed circuit boards. That’s a build that requires a lot of work, and this small, compact etching station does everything you need without taking up too much space in the shop. Check out the video below.

How To Turn A Chainsaw Into A Chopsaw
» ‎ Hack a Day

If you’re doing a lot of metal working, a chop saw is a great tool to have. It’s an easy and quick way to do a lot of neat, clean accurate cuts. [Making Stuff] wanted to do just that, but didn’t have a chop saw lying around. Instead, an old Stihl chainsaw was placed on the bench, and hacking ensued (Youtube link, embedded below).

To achieve this, it was necessary to source some parts and make some modifications to the chainsaw. The clutch bell was removed, and modified to mount a roller chain sprocket. An arm was then built, which mounted a pair of journal bearings at the far end. Another sprocket was installed at this end, along with a shaft which mounts the cutting wheel. Finally, a guard was fitted over the cutting wheel to give the build a semblance of safety.

[Making Stuff] notes that the chainsaw can readily be converted back to its standard purpose, needing only to refit the original parts and replace the modified clutch bell with a stock one. It’s a great way to get two tools out of one, and we’re sure it will prove useful in future projects.

If you’ve got a taste for wacky chop saws, check out this hard drive build. Video after the break.

Hacked Calipers Make Automated Measurements a Breeze
» ‎ Hack a Day

Now, digital calipers with wired interfaces to capture the current reading are nothing new. But the good ones are expensive, and really, where’s the fun in plugging a $75 cable into a computer? So when [Max Holliday] was asked to trick out some calipers for automating data capture, he had to get creative.

[Max] found that cheap Harbor Freight digital calipers have the telltale door that covers a serial connector, making them a perfect target for hacking. A little Internet sleuthing revealed the pinout for the connector as well as some details on the serial protocol used by most digital calipers: 24-bit packets is six four-bit words. [Max] used his SAM32, a neat open-source board with both a SAMD51 and an ESP32 that can run CircuitPython. An inverting buffer interfaces the serial lines to the board, which is just the right size to mount on the back of the caliper head. It’s hard to tell how [Max] is triggering readings, but the SAM32 is mounted as a USB device and sends keystrokes directly to a spreadsheet – yes, with the ESP32 it could have been wireless, but his client specifically requested a wired setup. Taking multiple readings is easy now that the user never has to swap calipers for a pen.

Cheap calipers like these are pretty hackable – you can add Bluetooth, turn them into DROs for a milling machine, or even make them talk.

Automatic Cut-Off Saw Takes The Tedium Out Of A Twenty-Minute Job
» ‎ Hack a Day

For [Turbo Conquering Mega Eagle], the question was simple: Do I spend 20 minutes slaving away in front of a bandsaw to cut a bunch of short brass rods into even shorter pieces of brass rod? Or do I spend days designing and building an automatic cutoff saw to do the same job? The answer is obvious.

It’s only at the end of the video below that [TCME] reveals the need for these brass bits: they’re for riveting together the handles of knives he makes and sells. That makes the effort that went into his “Auto Mega Cut-O-Matic” a little easier to swallow, although we still think he ran afoul of this relevant XKCD. The saw is built out of scraps and odd bits using angle iron as a base and an electric die grinder to spin a cut-off wheel. A small gear motor feeds the brass rod down a guide tube until it hits a microswitch stop, which starts the cut cycle. Another motor swivels the saw to make the cut then moves it out of the way so the stock can advance. The impressive thing is that the only control mechanism is a series of microswitches, cams, levers, and springs – no Arduino needed. Heck, there’s not even a 555, which we find a refreshing change.

Yes, it’s overkill, but he had fun and made something pretty ingenious. [Turbo Conquering Mega Eagle] always has something interesting going on in the shop, and we couldn’t help but notice him using his aluminum-melting tea kettle to make some parts for this build.

Seeing Transistors Switch In Infrared
» ‎ Hack a Day

In the hacker and DIY community, there are people who have exceptional knowledge and fantastic tools. These people are able to do what others could only dream about, and that others can only browse eBay looking for that one tool they need to do the job. One of these such people is [John McMaster]. He is the resident expert on looking inside integrated circuits. He drops acid on a chip, and he can tell you exactly how it works on the inside.

At the hardwear.io conference, [John] shared one of his techniques for reverse-engineering intgrated circuits. He’s doing this by simply looking at the transistors, and looking at the light they give off. He’s also looking at the wrong side of the die.

The technique [John] is using is properly called backside analysis, or looking at the infrared emissions of electron recombinations. This happens at the junction of every transistor when it’s active, and these photons are emitted at the bandgap of silicon, or about 1088 nm, far into the infrared. This sort of thing has been done before by [nedos] at CCC in 2013, but rarely have we seen a deep dive into the tools and techniques needed to look at the reverse side of an IC and see the photons coming off.
An IC, seen in infrared
There are several tools [John] used for this work, and he actually did a good comparison of different camera technologies used to image infrared photon emissions from integrated circuits. InGaAs cameras are expensive, but they offer high sensitivity. New back-illuminated CMOS cameras and cooled CCDs normally reserved for astrophotography were also tested, and as always, you get what you pay for; the most expensive cameras worked best, but there were ways you could make the cheap ones work.

As with any camera work, preparing the lighting is of utmost importance. This includes an IR pass filter, and using only LED lighting in the lab with no sunlight, incandescent, or halogen light bulbs in the room — you don’t want any IR, after all. A NIR objective in the microscope was sourced from eBay, for about 1/10th the normal cost, because the objective had a small, insignificant scratch. Using this NIR objective made the image twice as bright as any other method. You can successfully image a chip with this, and [John] tested the setup on a resistor inside a CD4050 chip; the resistor glowed a slight purple, the color you would expect with infrared sensors. But can it work with I/O levels in a more modern chip? Also, yes. It needs some Photoshop to process, and stretching the 12-bit or 16-bit color space into an 8-bit color space, but it does work.

Finally, the supreme achievement of doing backside IR analysis. Is that possible with even this minimal setup? This requires some preparation; the silicon substrate in an IC is transparent in IR, but there is attenuation and this is especially important when the substrate is 300 um thick. This needs to be shaved down to about 25 um thick, which surprisingly is best done with fine sandpaper and a finger.

While few IR emissions were observed via backside emissions, the original plan wasn’t to completely analyze the chip, but merely to do some floor planning. For this, it worked. It’s a remarkable amount of work to see the inside of a silicon chip.

Digital Multimeasure Helps You Get The Job Done
» ‎ Hack a Day

In any mechanical field of work, accurate measurement is key to success. [Patrick Panikulam] knows this well, and decided to build a device that would be useful for some of the more tricky measurement tasks he was encountering.

[Patrick]’s digital multi-functional measurement tool packs a bunch of useful hardware into a pocket-sized form factor. There’s a Sharp IR distance sensor for non-contact measurements, a rotary wheel encoder for measuring distances along curved lines, and an MPU6050 IMU packing accelerometers and gyroscopes for measuring angles and surface levels. Control is via touch buttons, so measurements can be taken without disturbing the position of the device.

The use cases for such a device are many and varied. [Patrick] reports using it to verify that his 3D printer bed is leveled, as well as using it to measure curved surfaces in order to accurately cut stickers to suit. It’s got the hardware to serve as a digital protractor, too.

Combining a variety of useful hardware into a compact form factor, while also taking into account usability, has netted [Patrick] a handy tool. It’s not dissimilar from commercial measurement tools available online, and yet is completely built from off-the-shelf parts. Truly a handy device to have in any hacker’s toolbox!

Adding Bluetooth Control To A Benchtop Power Supply
» ‎ Hack a Day

In 2019, it’s possible to kit out a lab with all the essentials at an even cheaper price than it has ever been. The DPS3005 is one such example of low-cost equipment – a variable power supply available for less than $50 with a good set of features. [Markel Robregado] wanted a little more functionality, however, and got down to work.

The crux of [Markel]’s project is improved connectivity. A Texas Instruments CC2640R2F Launchpad is employed to run the show, with its Bluetooth Low Energy capability coming in handy. A custom smartphone app communicates with the Launchpad, which then communicates with the power supply over its Serial Modbus interface. Through the app, [Markel] can set the voltage and current limit on the power supply, as well as switch it on and off. This could prove useful, particularly for remote triggering in the case of working with dangerous projects. Sometimes it pays to take cover, after all.

We’ve seen power supplies modified before; this pot mod for higher precision is a particular treat. If you’ve hacked your bench hardware for better performance, let us know. Video after the break.

Assembling A Lathe From Not A Lot
» ‎ Hack a Day

Most people have a piece of equipment without which they consider their workshop or bench to be incomplete. For some, it is an oscilloscope, for others a bandsaw, but for many metalworkers, it is a lathe. Lathes are expensive if you are seeking a good one, quite cheap if you don’t mind a bad one, and sometimes even free if you can deal with a good one that’s very old and needs six burly friends and a forklift truck to move.

There is another way to acquire a lathe, and it’s one that [Sek Austria] demonstrates in the video below the break: build your own. It’s a fascinating demonstration of how machine tools evolved with each successive generation made by the last at every increasing precision. He achieves good-enough construction from a welded steel frame with little more than hand tools, and though his result is by no means a perfect lathe it does allow him to achieve the next level of machining precision. Off the shelf come a set of optical guide rails and linear bearings along with a chuck and tool holder, but the rest is all his. And the washing machine motor driving it is a touch of pure class, even though he is embarrassed enough to cover it with a glove for filming. Sometimes in our community, we adopt the sledgehammer to crack a nut methodology, using CNC or similar techniques to fabricate things that can be made more speedily with less accomplished methods. We couldn’t help wincing at his hammering in the vice to create the lead screw nut bracket, though.

As homemade lathes go, this one is surprisingly conventional. Others have been fashioned from engine parts, or concrete.

Thanks [Xavier] for the tip.

You Don’t Need That Bulky CRT Oscilloscope Anymore
» ‎ Hack a Day

While it might be nice to use a $4,000 oscilloscope in a lab at a university or well-funded corporate environment, a good portion of us won’t have access to that kind of equipment in our own home shops. There are a few ways of getting a working oscilloscope without breaking the bank, though. One option is to find old CRT-based unit for maybe $50 on craigslist which might still have 60% of its original 1970s-era equipment still operational. A more reliable, and similarly-priced, way of getting an oscilloscope is to just convert a device you already have.

The EspoTek Labrador is an open-source way of converting a Raspberry Pi, Android device, or even a regular run-of-the-mill computer into a working oscilloscope. It’s a small USB device with about a two square inch PCB footprint that includes some other features as well like a signal generator and logic analyzer. It’s based on an ATxmega which is your standard Arduino-style AVR microcontroller but geared for low power usage. It looks as though it is pretty simple to use as well, and the only requirements are that you can install the software needed for the device on whatever computing platform you decide to use.

While the Labrador is available for sale at their website, it is definitely a bonus when companies offer products like this but also release the hardware and software as open source. That’s certainly a good way to get our attention, at least. You can build your own if you’d like, but if you’d rather save the time you have pre-built options. And it doesn’t hurt that most of the reviews of this product seem to be very favorable (although we haven’t tried one out ourselves). If you’d prefer an option without a company backing it, though, we have you covered there too.

Solder SMDs With A Pan O’ Sand
» ‎ Hack a Day

For those that grew up working with through-hole components, surface mount parts can be challenging to deal with. However, there are plenty of techniques out there that are more than accessible to the DIY set. With the right gear, soldering SMD boards is a snap – just get yourself a hot pan of sand (Youtube link, embedded below)!

The process starts with a professionally manufactured PCB, and accompanying stencil. All major PCB CAD packages are capable of generating stencil files these days, and many manufacturers will throw in a laser cut stencil for minimal extra cost with a PCB order. The board is first mounted on a stable surface, and has solder paste applied, before components are placed with tweezers. Perfect placement isn’t necessary, as the surface tension of the molten solder pulls components into their correct orientations. The populated board is then placed on a bed of sand in a frying pan, which is placed on an induction cooktop. The board is then heated until the solder melts, and all the components are neatly reflowed. Once allowed to cool, the board is done!

The trick is that the sand helps evenly heat the circuit board, while keeping it a safe distance away from the heat source. Results are good, and the process is far quicker than hand soldering. It’s easy to keep an eye on the process too. Of course, the traditional method is still to use the humble toaster oven, but new techniques are always useful. We’ve seen it done with a Bunsen burner, too. Video after the break.

3D Printed Knife Sharpening Tool Makes The Job Easy
» ‎ Hack a Day

A sharp knife is a joy to use, but many of us are guilty of buying the cheapest kitchen tools available and rarely maintaining them. Keeping knives sharp is key to working with them both safely and effectively, but to sharpen by hand requires patience and skill. [CNC Kitchen] instead decided to use technology to get around the problem, designing a 3D-printed tool to make the job easy (Youtube video, embedded below).

The knife sharpener is a straightforward build, requiring a few simple 3D printed parts in combination with some nuts, bolts, and aluminum rods. It’s designed to use commonly sized whetstones, which makes procurement easy. The design has undergone refinement over the years, with [CNC Kitchen] adding pockets for the magnets and a spherical bearing which reduces slop in the movement.

[CNC Kitchen] reports that the tool works wonderfully, allowing even a novice to sharpen knives well. Parts are available on Thingiverse for those who wish to print their own. If however, you insist on doing things the old-fashioned way, you can get an electronic coach to help improve your technique. Video after the break.

glScopeClient: A Permissively-Licensed Remote Oscilloscope Utility
» ‎ Hack a Day

One of the most convenient things about modern digital oscilloscopes is that you can access the recorded data on a computer for later analysis, advanced protocol debugging, or simply the convenience of remote capture. The problem is that the software isn’t always ideal. Vendor-supplied utilities are typically closed-source and they try to nickel-and-dime you for every a-la-carte protocol and/or feature. The open-source options come with their own issues, from performance-limiting designs, to incomplete features, to license constraints. Faced with these issues, [Andrew Zonenberg] decided to take matters into his own hands and create glscopeclient, a permissively-licensed open-source remote oscilloscope utility.

The eventual goal is to allow you to do remotely anything you would normally do using the scope’s front panel, plus capture and analyze data on the computer side. The code uses a modular architecture that allows for various backends to talk to different scopes. At the moment, the only backend fully implemented is for LeCroy scopes, although this is enough to demonstrate the power of the idea. The obvious “gl” in the name gives away the secret — the code uses OpenGL for rendering, which allows for some very fancy graphics at high frame rates.

Behind the slick look, however, are some serious debugging tools. Protocol analyzers include USB, UART, JTAG, eye pattern analysis, plus FFT-based spectra with waterfall displays. The code is in GitHub, and most of the announcements and discussion seem to happen on [Andrew]’s twitter account, which you can follow @azonenberg. It’s a work-in-progress, but a serious one, and something we’re going to keep our eyes on.

You can check out a video of the program after the break.

Now, if you want to literally talk to your oscilloscope, we covered that, too.

Tiny Forklift Makes Unusable Space Usable
» ‎ Hack a Day

Houses with crawlspaces are fairly common in some geographic regions. The crawlspace can make it easier to access things like plumbing and electrical wiring, and can even be used as storage in homes that don’t (or can’t) have a basement. Along with improved building ventilation, these some of the perks compared to homes built on a solid slab of concrete. These crawlspaces aren’t exactly easy to get around in, though, but [Dave] has an easier way to get stuff in and out of these useful, but small, spaces.

Enter the crawl space forklift. Made with largely off-the-shelf components, the robot includes a few standard motors and linear actuators to move around and operate the front fork. That’s all pretty standard, but this build really shines with its use of FPV camera, monitor, and transmitter that allow the pilot to navigate the robot in the small space using remote control. For those safety-conscious among us, there is also a fire extinguisher ball on board which self-activates in case the robot catches on fire under his house.

This is a great, high-quality build that shows how common parts can make something revolutionary with the right idea. Identifying a problem and then building a solution, while not forgetting to spring for some safety equipment, can really make a difference even with something as simple as unoccupied space in a home. They can tackle tasks around the home, too.

Visualizing How Signals Travel In A PCB
» ‎ Hack a Day

If you play with high speed design for long enough, eventually you’re going to run into clock skew and other weird effects. [Robert Feranec] recently ran into this problem and found an interesting solution to visualizing electric fields in a PCB.

A word of warning before we dig into this, for most of the projects we see on Hackaday something like this is completely superfluous. There aren’t many people dealing with high speed interfaces here, and there aren’t many people dealing with 100 Gigabit per second data links, period. That said, it’s not unheard of, and at the very least it’s interesting to look at.

The basics of this video is simulating the signals visually in a differential pair on a (virtual) printed circuit board. The software for this is Simbeor, and [Robert] talked to the founder of the company behind this software after watching a video on simulating electric fields in differential traces. This software does what it says, and is a great illustration of why differential pairs must have the same length.

While this might not be for everyone, it is a fantastic visualization of signals in high-speed design that goes above and beyond what you would expect from a Spice simulation. Even if you’re not doing high-speed design, you may someday and it’s never too soon to get an intuitive understanding of how electrons work.

Build A Sheet Metal Brake With No Welding Required
» ‎ Hack a Day

Sometimes, there’s a job to be done and the required tools don’t fall easily to hand. [Bob] found himself in just such a position, needing to get some window flashing made up despite lacking a sheet metal brake. After waiting far too long for someone else to do the job, [Bob] elected to simply make the tools and do it himself instead (Youtube link, embedded below).

The project came about simply because [Bob] needed to bend 42″ sections of flashing, and couldn’t find a decent deal on a sheet metal brake above 36″ wide. The build starts with some angle iron and simple hinges, bolted together to form a basic brake design. With some rectangular hollow section bolted on for handles, the brake is then clamped to the bench and is ready for action.

It’s a build that any experienced hacker could whip up in an afternoon and be pumping out basic sheet metal parts by sundown, and requires no welding to boot. To learn more about bending sheet metal, check out our primer on the subject. Video after the break.

Unfortunately though, most meters won’t read very low values. There are tricks you can use to achieve that aim, such as measuring low currents through a device with a known voltage applied. It is handier though to have an instrument to make the reading directly, and [Kasyan TV] did just that with a surprisingly low part count.

The whole thing is built from an LM317, a resistor, and a voltmeter module, that’s it. [Kasyan] mentions the meter’s accuracy means the lower digits are not meaningful, but it looks to us as though there are other sources of error — for example, there’s no way to zero out the probe’s resistance except during the initial calibration.

This isn’t going to be perfect — you’d do better with a 4-wire measurement and a way to zero set shorted probes. However, it does seem to work well enough and it is a simple, but useful, project.

Our favorite quote is this one:

The case itself was printed on a 3D printer. It turned out ugly and not neat, but I don’t care much.

Sounds like a good way to think about it.

We’ve seen homemade meters like this before, but they were more complicated. We’ve even seen them cobbled together which is fine if you don’t care much.

CNCing An X-Acto Knife Holder
» ‎ Hack a Day

X-acto knives are popular as the scalpel of the craft world. Obviously, holders for the blades are available off-the-shelf, but you needn’t settle for store bought. [Ariel Yahni] set about making an X-acto handle of their own, and it shows just how quick and easy making your own tools can be.

The blades are first measured to determine the appropriate dimensions for the holder. With this done, the basic shape of the handle is drawn up in CAD software using simple primitive shapes and lines. Then it’s just a simple matter of jigging up a piece of aluminium stock in the CNC machine, and letting it do its thing.

The final result needs minimal finishing – primarily just an inspection of the parts, minor deburring and the drilling and tapping of the mount holes. With a couple of socket head cap screws and an X-acto blade installed, it’s ready for work.

We see a lot of interesting tool builds around these parts. You might consider making your own ultrasonic cutter if you’re regularly finishing 3D printed parts. Video after the break.

Better Simulators With Homemade Potentiometers
» ‎ Hack a Day

Perhaps you’ve played a flight simulator before, using something like a mouse and keyboard. That’s a fine experience, but like any other activity you can get a lot more out of it if you put a little more effort into the experience. Some will upgrade to a joystick for a modest improvement, and others will build incredible accurate cockpit replicas down to the smallest detail. The builders of these “pits” are always looking for ways of improving their setups, and it’s from this world that we find a method of building specialized, inexpensive hall-effect sensors.

A hall-effect sensor is a circuit that outputs a voltage based on the presence of an external magnetic field. These can be used to make compasses, but with a permanent magnet in close proximity can also be used to create a potentiometer-like device at lower cost and with higher precision than a similarly-priced pot. There was a method of building these in the simulator world using the housing of a Bic pen and some strong glue, but [LocNar] has improved on this method as well. He repurposed some bearings and some stock metal tubing in order to fabricate a professional-level sensor at a fraction of the cost.

This build is essentially a solution for anyone needing a potentiometer that’s easier to build, less expensive, has higher precision, and interacts with a digital input in a much more predictable (and programmable) way. Certainly this has applications in the simulator world, but will work for many other applications. If you’ve never thought about the intricacies (and shortcomings) of potentiometers, some other folks have taken a deep dive into that as well.

Thanks to [Keith O] for the tip!

Set Your Nuts (and Bolts) Free with this Induction Heater
» ‎ Hack a Day

[Amon] built an induction heater to break stuck bolts loose. If you work on cars, machines, or anything big and metal, sooner or later you’re going to run into stuck nuts and bolts. Getting them unstuck usually involves penetrating oil, heat from a torch, and cheater bars. Heat usually works well, as heating the bolt makes the metal expand, helping it to break free. Torches aren’t exactly precision instruments though, and things can get interesting using one in tight spaces.

Fire isn’t the only way to heat a bolt through. Electricity can do the job as well. But why use a heating coil when you can grab an induction heater. Mechanics have had induction heaters in their toolboxes now for a few years, under names such as Bolt Buster or Mini Ductor. These devices cost several hundred dollars. However, you can purchase a 1000 watt induction heater from the usual sources for around $30. These are open frame Zero Voltage Switching (ZVS) power supplies, with uninsulated copper coils.

[Amon] bought one of these induction heaters, along with a beefy 24V, 40 amp switch mode supply to power it. He built the two into a plastic enclosure. A relay energizes the induction heater, so it isn’t always running. The key to this build is the handle. Rather than mount the induction coil directly on the supply, [Amon] ran two extension wires to a 3d printed gun style handle. This keeps the bulky part of the heater away from the work. The copper tube coil was re-shaped to better work with the gun. Some fiberglass sleeve keeps everything insulated, even at extreme temperatures.

The result is a very useful heater, ready to bust loose some bolts. We’ve seen homebuilt ZVS supplies powering induction coils before. It will be interesting to see how well these commercial units hold up.

Paperclip Breadboard
» ‎ Hack a Day

TV’s MacGyver would love the breadboard arrangement we saw recently: it uses paperclips and crimping to make circuits that can be more or less permanent with no soldering. The basic idea is simple. A cardboard base has a piece of paper affixed. Metal paperclips are bent straight and glued to the paper using PVA glue (you know, like ordinary Elmer’s; hot glue would probably work, too). You could probably salvage wires out of old house wiring that would work for this, too.

The scheme uses two sizes of paper clips. Large ones are made straight and form the rails, while small paperclips make connections. The rails are bent to have a little “ear” that pushes into the cardboard base to hold them still. A little glue stabilizes them. The ears poke out the back, so the author suggests covering them with duct tape, hot glue, or another piece of cardboard. Using the top of a shoebox would also solve the problem.

Using pliers, the smaller paperclips are made to grip components. Obviously, you’ll need through-hole components and any sort of IC will probably require a little adapter board. This technique is really better for simple circuits with no ICs. For quick connections, you can crimp a single hook or use a double hook for a stronger connection that is harder to install.

There are other makeshift items included such as a magnetic battery holder. If you really prefer to solder, we’ve done something really similar using copper foil tape as the rails. You can find this tape at craft stores that sell supplies for staining glass. You can actually treat the tape like a PCB trace so long as you remember to solder where they cross as the adhesive will probably insulate the two pieces of tape.

This would be a fun rainy day project with kids. We doubt it will displace the ubiquitous breadboard, although there are some ideas that are attempting to do just that. We’ve also seen other people use paperclips for a variety of unusual purposes — including the ever popular paperclip computer.

Design Tips For Easier CNC Milling
» ‎ Hack a Day

CNC machining is a wonderful thing, taking away a lot of the manual work required in machining and replacing it with accurate, repeatable computer control. However, this doesn’t mean that you can simply click a few buttons and become a great machinist overnight. There are a wide variety of skills involved in utilizing these tools effectively, and [Adam Bender] has created a guide to help budding makers learn the skills of design for CNC milling.

[Adam]’s guide starts from a basic level, considering 3-axis CNC milling with the most commonly used tools. From there, a whole range of tips, tricks, and potential pitfalls are discussed to help new machinists get to grips with CNC milling. Everything from dogbone corners, to tool selection and feature heights are covered, as well as cost-saving techniques like minimising the number of setups required.

These are skills any engineer will learn in a hurry when approaching an experienced CNC machinist, but it’s always better to go in forewarned and forearmed. Of course, for those eager to not just work with, but build their own CNC machine, we’ve covered that base too. Video after the break.

Air Compressor From Fridge Parts Gets An Upgrade
» ‎ Hack a Day

Air compressors are often loud, raucous machines – but they don’t have to be. [Eric Strebel] built a remarkably quiet compressor using parts salvaged from an old fridge. After several years of use, it was due for an upgrade (Youtube link, embedded below}.

While performance of the original setup was good, [Eric] desired a compressor with more capacity for his resin casting activities. A 15 gallon air tank was sourced from a damaged Craftsman brand compressor, and pressed into service. The build involved plenty of sheet metal work to mount the various components, as well as an upgrade to the pressure regulator.

During the refit, [Eric] takes the time to answer questions from the audience about his original build. He notes that the fridge compressor has worked well without using any noticeable amount of oil, and that there was a problem with water build up in the original tank which has been solved in the new rig.

It’s a great example of building your own tools, which can provide years of service if done right. Check out our write up on [Eric]’s first build, or his work on photogrammetry. Video after the break.

Modular CNC Build Gets You Both a Mill and a Laser Cutter
» ‎ Hack a Day

CNC builds come in all shapes and sizes. There’s delta manipulators, experimental polar rigs, and all manner of cartesian builds, large and small. After completing their first CNC build, [jtaggard] took what they learned and applied it in the development of a new machine.

It’s a desk-sized cartesian design, with a frame built from V-slot extrusion cut to size by circular saw. This is a great way to get quality extrusion for a custom build, and is readily available and easy to work with. The gantry rides on wheels, with the X and Y axes being belt driven, plus a screw drive for Z. A couple of NEMA 17s and a NEMA 23 provide motive power, and an Arduino Uno with stepper drivers is the brains of the operation. 1/4″ thick PLA plates are used to assemble everything, and while [jtaggard] intended to replace these with aluminium down the track, so far the plastic has proved plenty rigid enough for early tests of both machining and engraving wood.

It’s a great entry-level CNC build, which has proved usable with both a 500W spindle and a 2.5W laser for engraving. Being modular in nature, it would be easy to add other tools, such as a pen plotter or vinyl cutting blade for further versatility.

DIY CNC builds are always popular, as you end up with a useful tool as a reward for your hard work. Video after the break.

Repairing And Upgrading A HP 16533A Scope Card
» ‎ Hack a Day

In the world of oscilloscopes, as in the rest of the test equipment world, there’s always some trickery afoot. Companies will often offer different models to the market at different price points, in an effort to gain the widest possible customer base while also making the most profit. Cheaper, less capable models are often largely identical to more expensive hardware, save for some software or a couple jumpers that disable functionality. [Alexandre] found just this when working to repair his HP 16533A scope card.

Work began when [Alexandre] received his HP 16533A in the mail after a long wait, only to find the trigger functionality was inoperable. This is crucial on a digital scope, so this simply wouldn’t do. After some research online, a post was found discussing which signals to probe to troubleshoot the issue. It noted that corrosion is a common problem on these units, and that occasionally, a certain resistor goes open circuit and causes problems. Initial measurement showed there was still resistance there, but reading closer, [Alexandre] noted this fateful line:

You might not be able to measure it accurately in circuit.

Removing the 100K resistor from the board, the part was indeed open circuit. After replacement with a new component, the trigger circuit was again fully operational. With the scope still open, it was then a simple job to execute a further resistor swap which gives the 16533A the functionality and range of the higher-spec 16534A model.

It’s very common for oscilloscopes and other test hardware to be configured this way from the factory. Rigol scopes are particularly popular with hackers for this very reason.

Big, Slow Rotary Machine Has Multiple Uses
» ‎ Hack a Day

A good majority of power tools in the average workshop are all about speed. Drills, grinders, and sanders all whizz along at thousands of revolutions per minute. Sometimes though, you need to do things slowly. For that, [bongodrummer]’s big rotary machine build might be just up your alley.

The core of the build is an old washing machine, which supplies both the machine frame and its powerful universal motor. While this can be hooked directly to a power source and allowed to spin away, it’s far more useful with some speed control in place. For this, an Arduino is hooked up to a triac circuit with feedback, allowing the speed to be set just so for whatever operation you have in mind. A set of speed-reducing pulleys helps further for getting down into the double-digit RPM while maintaining smooth rotation. There’s even a timer for extended operation, with parts salvaged from an old microwave.

The machine is built with a large rotating platter on top. By placing a clean white screen on top, the platter is great for taking 360 degree photos of objects automatically. This could be of great use in a photogrammetry setup. Alternatively, by fitting a bowl and plough assembly, the machine can be used to mull green sand for casting purposes.

It’s a versatile build that could be used for anything that needs rotation in the vicinity of 50 rpm. You could even play vinyl records on it if you were so inclined. Of course, if you’ve built a record player out of an old washing machine, we’d certainly like to know about it.

3D Printed Parts Let You Hold Work The Way You Want
» ‎ Hack a Day

Fixturing and work holding can be huge problems for hackers. Let’s face it – that $5, alligator clip-festooned “Helping Hand” is good for only the smallest of workpieces, and the problem only gets worse as the size scales up. One can jury rig fixtures for things like microscopes and lights, but a systematic approach like this 3D-Printed work fixturing Erector Set really appeals to our need for organization.

As [Tinkers Projects] explains it, the genesis of this project came from a need to mount a microscope firmly over a PCB. Rather than build a one-off fixture, the idea of a complete system of clamps and connectors seemed to make more sense. Based on 10-mm aluminum rods and a bewildering number of 3D-printed pieces, the set has just about everything needed to fixture pretty much anything. There’s a vertical element that acts as the central support, connectors for putting another rod perpendicular to that, plus neat attachments like a three-fingered clamp for small cylindrical objects and a couple of blocks that act like a stick-vise for PCBs and similar workpieces. And yes, there’s even a fixture with alligator clips. The whole thing seems very well thought out and has a little mad scientist vibe to it, but while some fixtures look as if they came right from the chemistry lab, we’d be cautious about chemical compatibility and use near heat sources.

[Elliot Williams] did a rundown of what people are using for helping hands a couple of years ago which made us covet articulating dial indicator arms for our bench. Still, [Tinkers Projects]’ approach has a lot of appeal and is probably cheaper and more versatile to boot.

How To Build A Small Metal Furnace At Home
» ‎ Hack a Day

Casting is a great way to make your own custom metal parts. However, casting requires some manner of furnace capable of generating high enough temperatures to melt the metal in question. Few of us have these just lying around, but never fear. It’s possible to build a basic gas-powered furnace at home, with commonly available materials (Youtube link, embedded below).

This furnace is the work of [Ahmed Ghr], and is as simple a build as they come. The idea is to produce a mold in which to cast concrete to create the furnace. A steel bucket is cut up and used as the outside of the mold, with a pipe inserted in the base to act as a feeder for air and gas. A plastic bucket is then inserted within the steel bucket and held in place with spacers, to create the inner combustion cavity. Concrete is poured in and allowed to set. Once finished, the steel bucket is cut away, and a fire is built over the furnace to melt away the plastic inside. Similar techniques are used to produce the lid, and the furnace is completed.

It’s a build that is executed with the most basic of tools, and should serve as a capable furnace for lower melting point metals at the very least. We’ve seen a lot of cement projects lately, as it turns out. Video after the break.

Camera Sees Electromagnetic Interference Using an SDR and Machine Vision
» ‎ Hack a Day

It’s one thing to know that your device is leaking electromagnetic interference (EMI), but if you really want to solve the problem, it might be helpful to know where the emissions are coming from. This heat-mapping EMI probe will answer that question, with style. It uses a webcam to record an EMI probe and the overlay a heat map of the interference on the image itself.

Regular readers will note that the hardware end of [Charles Grassin]’s EMI mapper bears a strong resemblance to the EMC probe made from semi-rigid coax we featured recently. Built as a cheap DIY substitute for an expensive off-the-shelf probe set for electromagnetic testing, the probe was super simple: just a semi-rigid coax jumper with one SMA plug lopped off and the raw end looped back and soldered. Connected to an SDR dongle, the probe proved useful for tracking down noisy circuits.

[Charles]’ project takes that a step further by adding a camera that looks down upon the device under test. OpenCV is used to track the probe, which is moved over the DUT manually with the help of an augmented reality display that helps track coverage, with a Python script recording its position and the RF power measurements. The video below shows the capture process and what the data looks like when reassembled as an overlay on top of the device.

Even if EMC testing isn’t your thing, this one seems like a lot of fun for the curious. [Charles] has kindly made the sources available on GitHub, so this is a great project to just knock out quickly and start mapping.

A Stylish Low Part Count Non-Contact Thermometer
» ‎ Hack a Day

A non-contact thermometer is a pretty common tool these days, and one that most of us probably have kicking around the lab. You can grab them online for as little as $10 USD, and while they’re nowhere near as capable as a thermal camera, they certainly have their uses. But even with their increased availability, there are at least two safe assumptions we can make about owners of said gadgets: they didn’t make it themselves, and they are probably pretty ambivalent about its aesthetics.

Which makes this project by [Ijon Tichy] particularly interesting. Not only is this a non-contact infrared thermometer that’s extremely easy to build should you be so inclined, but it’s actually quite attractive. In fact, if it wasn’t for the video of it in operation after the break, we would have assumed it was some kind of faux-retro cosplay prop. Even if you don’t have any use for an IR thermometer, you might just want to add one of these to your toolbox on principle.

The main components of the thermometer are a MLX90614 sensor, a gorgeous HP QDSP-6040 bubble display, and a ATtiny2313 microcontroller to tie it all together. The rest are passive components, with the exception of the TP4056 charging module that got tacked on to handle the 200 mAh lithium-ion battery. All of the components are arranged neatly in a line down the length of the thermometer, which is assembled on a piece of perfboard. Rather than go with a 3D printed enclosure that would cover it all up, [Ijon] decided to encapsulate everything in a clear epoxy resin. It looks fantastic, though you’re going to want to triple check all those solder joints before pouring on your “enclosure”.

[Ijon] has provided the diagrams and source code you need to build your own version of this artisanal thermometer, but we think with a custom PCB and perhaps a less liquid enclosure that still shows off the goods, this could be a very popular gadget for the discerning hacker. As we’ve seen, even the most basic of tools can benefit from a stylish makeover.

How Much Wood Can a Woodpecker Chuck?
» ‎ Hack a Day

It’s probably clear to a Hackaday reader that we live in a golden era for hobbyist tool accessibility. Cheap single board computers can be bought at any neighborhood ~~RadioShack or Maplin~~. 3D printers sell fully assembled and ready to run for less than $200. Even the humble CNC mill has come down the price curve, though as you might expect at the low end things can get pretty rough. Like a cheap 3D printer, a cheap mill tends to be missing some basic features you’d expect any reasonable machine to have. If you get your hands on one of these little wonders, [Shahada Abubakar] has a pair of great blog posts on the basic set of upgrades you’ll probably want to perform right out of the box.

Which cheap CNC mills are we talking about? They go by a few names. Last year our own [Kristina Panos] put together a review of a shockingly inexpensive “1610” type sold by Linksprite (go take a read if you’re already considering a purchase!). The “1610” class, so named for it’s 16 cm x 10 cm bed size, is pretty common under a wide variety of manufacturer names. You can find them in this size made of 8020 like [Kristina] did or as “upgraded” versions cut from 1/4″ mystery plastic (often referred to in the listings as Bakelite, but your guess is as good as ours as to the true material). 1610 is the smallest size but basically the same machine exists as an 1810, 2418, or 3018. Each has a 775 size spindle and a single PCBA that handles stepper drive and runs grbl.

So what’s the problem? Well for one none of these machines have limit switches, though the controllers support them. [Shahada]’s guide has handy instructions for what kind to buy, how to wire them, and where they can be attached. Plus an overview of the G-code instructions to send the controller in order to home and configure everything properly. The controllers also like to be driven continuously over serial (though some sellers seem to offer a separate board to drive them). This is fine if you have a computer handy, but like a 3D printer it can be nice to bolt a Pi Zero or similar onto the unit and control it over the network. [Shahada]’s second post has a link to a mounting plate you can print for exactly that setup, as well as some suggestions for configuring CNC.js to drive everything.

Do you have one of these machines? Done any upgrades? Tell us in the comments! We’re always looking for ways to upgrade our home shop.

Power Measurement Oscilloscope Style
» ‎ Hack a Day

If you want to measure voltage you reach for a voltmeter. Current? An ammeter. Resistance? An ohmmeter. But what about measuring AC power? A watt meter? Usually. But if you know what to do, you could also reach for your oscilloscope. If you don’t know what to do, [Jim Pytel] has the video answers for you. Truth is, an oscilloscope can measure almost anything if you know how. [Jim] shows how to measure the voltage and current in a circuit and then it is simply a matter of doing a little math, something modern scopes can do very easily.

We like that [Jim] shows a circuit and how the math works before he verifies the math with the scope. Of course, theory doesn’t always match practice. The method uses a small current-sensing resistor that throws readings off a bit. The scope and signal generator are not perfect, either. However, the results match up pretty nicely with the computed results.

Electronics can be pretty abstract and the oscilloscope is probably the best tool for visualizing what’s going on inside. It used to be that hobbyists had to buy old surplus scopes to get something nice, but now you can get a fantastically capable scope for a few hundred dollars brand new.

Of course, if you like, you can pay over a million. Or, perhaps you’d like to visualize your signals in flames.

Get Your Acrylic Bends Just Right
» ‎ Hack a Day

Acrylic is a popular material. It’s easy to find, attractive, and available in all manner of colors, thicknesses, and grades. Being a thermoplastic, it’s also simple to apply heat and form it in various different ways. If you’re wanting to build parts out of sheet acrylic, you might find a purpose-built bender useful. [DIY Perspective] built just such a tool to get the job done.

Plywood is used as the base of the tool, and several off-the-shelf hinges are used to make the folding apparatus. Stops are cut out of scrap wood to allow the bender to accurately recreate angles of 45, 90, and 135 degrees. Heat is supplied via a nichrome wire, powered by a laptop power supply and a PWM controller. This allows the temperature of the wire to be controlled, to avoid melting or otherwise damaging the acrylic being bent.

If you find yourself routinely working with acrylic, you might find this tool useful to have around the workshop. Vacuum forming may also be relevant to your interests. Video after the break.

Mechanical Integration With KiCad
» ‎ Hack a Day

Eagle and Fusion are getting all the respect for integrating electronic and mechanical design, but what about KiCad? Are there any tools out there that allow you to easily build an enclosure for your next printed circuit board? [Maurice] has one solution, and it seamlessly synchronizes KiCad and FreeCAD. KiCad will give you the board, FreeCAD will give you the enclosure, and together you have full ECAD and MCAD synchronization.

This trick comes in the form of a FreeCAD macro (on the Github, with a bunch of documentation) that loads a KiCad board and components into FreeCAD and export them as a STEP file. You can align the KiCad board in FreeCAD, convert STEPs to VRMLs, check interference and collision, and create an enclosure around a KiCad board.

KiCad has gotten some really great visualization tools over the past few years, and we would be remiss if we didn’t mention it’s one of the best ways to visualize a completed circuit board before heading to production. Taking that leap from electronic CAD to mechanical CAD is still something that’s relatively rare in the KiCad ecosystem, and more tools to make this happen is always wanted.

JigFab Makes Woodworking Easier
» ‎ Hack a Day

Woodworking is an age-old craft that requires creativity and skill to get the best results. Experienced hands get the best results, while the new builder may struggle to confidently produce even basic pieces. JigFab is here to level the playing field somewhat.

Much of the skill in woodworking comes with mastering the various joints and techniques required to hold a piece together. Cutting these joints often requires specialized tools and equipment – ideally, some sort of jig. These jigs can be difficult to build in themselves, and that’s where JigFab shines.

The workflow is straightforward and quite modern. A piece is designed in Autodesk Fusion 360. Various joints can then be defined in the model between individual parts. JigFab then generates a series of laser cut constraints that can be used with power tools to easily and accurately cut the necessary parts to build the final piece.

It’s an impressive technology which could rapidly speed the workflow of anyone experimenting with woodwork and design. There’s even smart choices, like having a toolkit of standard predefined elements that reduce laser cutting time when producing new constraints. If you’re eager to get stuck in to woodwork, but don’t know where to start, don’t worry – we’ve got a primer for that. Video after the break.

A Breadboard Power Supply That’s More Universal Than Most
» ‎ Hack a Day

A favorite project of ours is the humble breadboard power supply. Yes, you can still prototype on breadboards, no, you don’t need an entire bench power supply to prototype on one, and every breadboard made in the last forty years has had the same pattern of holes. There’s plenty of opportunity to improve the breadboard power supply.

One of the best ones we’ve seen yet comes from [John Loeffler]. It’s a simple, constant voltage power supply that’s variable from 0.6 V all the way up to 12 V. It’s powered through a micro USB port, and you get 3.3 V and 5 V rails automagically. There’s even voltage indication.

The mechanical design of this power supply is simple enough, with pins that plug into the detachable power rails on either side of the breadboard. Where it gets interesting is the voltage indication. There’s a resistor ladder and a series of LEDs to indicate the voltage on the variable side of this power supply. Add in some modern switched mode power supply based on the MIC5225 series of chips (a popular regulator that’s very nice for the price) and you have a completely functional power supply hanging off a breadboard.

While it’s not a really nice rack mounted bench power supply that weighs a lot, or even one of the cheapo bench supplies, this does fulfill a need. Sometimes you just need a simple power supply for a breadboard, and this is one of the best ones we’ve seen yet.

A USB -C Soldering Iron For Weller Tips
» ‎ Hack a Day

There was a time when a decent temperature controlled soldering iron took the form of the iron itself and a box of electronics, but now it’s just as likely to be a miniaturised affair with the temperature controller built into a slim and lightweight handle. Irons such as the Miniware TS series have become firm favourites, displacing a traditional soldering station for many.

[Thomas.lepi] has combined the best of both worlds, with a TS-style microprocessor-driven handle driving the familiar Weller RT elements. Its interface is very simple, but through its USB power socket a serial port provides opportunities for adjustment. Providing control is an STM32F042G6U6 ARM Cortex M0 microcontroller, with USB power control coming from an STUSB4500QTR .

If you are used to irons such as the Miniware TS100 then this one with its smartly 3D-printed case will be very straightforward to use. Whether or not the ready availability of the TS100 or its USB-C sibling would remove the need to build this iron is up to you, but then again that’s hardly the point. The Weller tips are some of the better ones of their type, so perhaps that might make this project worth a second look.

Byte Sized Pieces Help The KiCad Go Down
» ‎ Hack a Day

It’s no surprise that we here at Hackaday are big fans of ~~Fritzing~~ KiCad. But to a beginner (or a seasoned veteran!) the learning curve can be cliff-like in its severity. In 2016 we published a piece linking to project by friend-of-the-Hackaday [Chris Gammell] called Contextual Electronics, his project to produce formalized KiCad training. Since then the premier “Getting to Blinky” video series has become an easy recommendation for anyone looking to get started with Libre EDA. After a bit of a hiatus [Chris] is back with bite sized videos exploring every corner of the KiCad-o-verse.

A Happy [Chris] comes free with every videoThe original Getting to Blinky series is a set of 10 videos up to 30 minutes long that walks through everything from setting up the the KiCad interface through soldering together some perfect purple PCBs. They’re exhaustive in coverage and a great learning resource, but it’s mentally and logistically difficult to sit down and watch hours of content. Lately [Chris] has taken a new tack by producing shorter 5 to 10 minute snapshots of individual KiCad features and capabilities. We’ve enjoyed the ensuing wave of learning in our Youtube recommendations ever since!
Selecting traces to rip up
Some of the videos seem simple but are extremely useful. Like this one on finding those final disconnected connections in the ratsnest. Not quite coverage of a major new feature, but a topic near and dear to any layout engineer’s heart. Here’s another great tip about pulling reference images into your schematics to make life easier. A fantastic wrapped up in a tidy three minute video. How many ways do you think you can move parts and measure distances in the layout editor? Chris covers a bunch we hadn’t seen before, even after years using KiCad! We learned just as much in his coverage of how to rip up routed tracks. You get the idea.

We could summarize the Youtube channel, but we aren’t paid by the character. Head on down to the channel and find something to learn. Make sure to send [Chris] tips on content you want him to produce!

Benchtop Lathe Gets An Electronic Leadscrew Makeover
» ‎ Hack a Day

The king of machine tools is the lathe, and if the king has a heart, it’s probably the leadscrew. That’s the bit that allows threading operations, arguably the most important job a lathe can tackle. It’s a simple concept, really – the leadscrew is mechanically linked through gears to the spindle so that the cutting tool moves along the long axis of the workpiece as it rotates, allowing it to cut threads of the desired pitch.

But what’s simple in concept can be complicated in reality. As [Clough42] points out, most lathes couple the lead screw to the spindle drive through a complex series of gears that need to be swapped in and out to accommodate different thread pitches, and makes going from imperial to metric a whole ball of wax by itself. So he set about building an electronic leadscrew for his lathe. The idea is to forgo the gear train and drive the leadscrew directly with a high-quality stepper motor. That sounds easy enough, but bear in mind that the translation of the tool needs to be perfectly synchronized with the rotation of the spindle to make threading possible. That will be accomplished with an industrial-grade quadrature encoder coupled to the spindle, which will tell software running on a TI LaunchPad how fast to turn the stepper – and in which direction, to control thread handedness. The video below has some great detail on real-time operating systems on microcontrollers as well as tests on all the hardware to be used.

This is only a proof of concept at this point, but we’re looking forward to the rest of this series. In the meantime, [Quinn Dunki]’s excellent series on choosing a lathe should keep you going.

This Air Compressor Sucks
» ‎ Hack a Day

Vacuum is something most people learn about as children, when they’re first tasked with chores around the home. The humble vacuum cleaner is a useful home appliance and a great way to lose an eye as an inquisitive child. When it comes to common workshop tasks though, they can be a bit of a let down. When you need to pull some serious vacuum, you might wanna turn to something a little more serious – like this converted air compressor.

The build starts with a cheap off-the-shelf tyre inflator. These can be had for under $20 from the right places. They’re prone to overheating if used at too high a duty cycle, but with care they can last just long enough to be useful. The hack consists of fitting a hose barb connection over the intake of the pump, to allow air to be sucked out of whatever you’re trying to pull vacuum on. This is achieved with some hardware store parts and a healthy dose of JB-Weld. It’s then a simple matter of removing the valve adapter on the tyre inflator’s outlet so it can flow freely.

You might also consider adding a check valve, but overall this remains a cheap and easy way to get an electric vacuum pump for your workshop up and running. If that’s not quite your jam, you can always go down the handpump route instead.

Casting CNC Parts In Aluminium
» ‎ Hack a Day

When it comes to machining, particularly in metal, rigidity is everything. [Tailortech] had a homebuilt CNC machine with a spindle held in place by a plastic bracket. This just wasn’t up to the job, so the decision was made to cast a replacement.

[Tailortech] decided to use the lost PLA process – a popular choice amongst the maker crowd. The spindle holder was first sketched out, then modeled in Fusion 3D 360. This was then printed in PLA slightly oversized to account for shrinkage in the casting process.

The PLA part was then used to make a plaster mold. [Tailortech] explains the process, and how to avoid common pitfalls that can lead to problems. It’s important to properly heat the mold once the plaster has set to remove moisture, but care must be taken to avoid cracking or wall calcination. It’s then necessary to slowly heat the mold to even higher temperatures to melt out the PLA prior to casting. With the mold completed, it can be filled with molten aluminium to produce the final part. When it’s cooled off, it’s then machined to final tolerances and installed on the machine.

Lost PLA casting is a versatile process, and goes to show that not everything has to be CNC machined out of billet to do the job. It’s also readily accessible to any maker with a furnace and a 3D printer. If you’ve got a casting project of your own, be sure to let us know. Video after the break.

Only 90s Kids Want Heelys Made From Pallet Wood
» ‎ Hack a Day

The kids are simply cooler than you. While you’re walking around using your feet like an animal, kids have shoes with wheels in their heels. These are called Heelys, and here’s how you make wooden clogs, with wheels in the heels, out of pallet wood. If you have to ask why, you’ll never know.

This build started off with a fairly large maple log, which would be the traditional way to build clogs. After taking this log to the bandsaw and looking inside, [Jackman] found a bit of spalting, or arguably aesthetically pleasing fungal growth. Whether the spalting would look good or not is a matter for debate, but either way [Jackman] decided to change plans and moved over to creating pallet wood clogs. A word of warning about pallet wood: you shouldn’t make anything out of wood from discarded pallets unless you know what you’re doing, and even if you do know what you’re doing there will be someone in the comments telling you that you shouldn’t use wood from discarded pallets. You can check out the comments to this article to verify this fact.

The construction of the clogs started with a few pieces of one inch stock glued up into a gigantic block, then several pieces of half inch stock resawn into quarter inch stock and laminated onto the sole of the clog. This was then shaped using a variety of tools from Arbortech; of note, we have the Turbo Plane, a wood shaping tool for a grinder that sounds more dangerous than it is, the Turbo Shaft, a plunge router or mortiser-sort-of-thing for a grinder that’s much cooler than it sounds, and the Power Chisel, something we can’t even believe exists and hold on here’s all our money.

These tools couldn’t get all the way into the toe of the clog, which meant [Jackman] had to saw down the middle and hollow everything out that way, but this did give him a nice flat surface on the inside to install the Heely wheels. This turns the clogs into something nine-year-olds simultaneously desire and don’t appreciate, because they’re kids.

These Wire Strippers Are Made From PCBs
» ‎ Hack a Day

The rise in cheap PCB fabrication has made old-school prototyping methods such as wire wrapping somewhat passé, but it still has its place. And if you’re going to wire wrap, you’re going to want a quick and easy way to strip that fine Kynar-insulated wire. So why not use PCB material to make this handy wire-wrapping wire stripper?

The tool that [danielrp] built is pretty simple – just a pair of razor blades held together so as to form a narrow slot to cut insulation while leaving the conductor untouched. The body of the tool is formed of two PCBs, between which the blades are sandwiched. [danielrp] designed the outline of the PCBs in DraftSight, then exported a DXF into EAGLE to make the Gerbers. The fabricated boards needed a little post-processing, including tapping the holes on one side to accept the screws that hold the tool together. We were surprised that FR4 took the threads at all, but it seems to work for this low-torque application. The disposable snap-type blades were sandwiched between the PCBs and the gap between them adjusted for nick-free stripping. The video below shows the design and build process.

We always appreciate homemade tools, and the fact that you can get a stack of PCBs for almost nothing makes us wonder what else we could use them for. We recently saw them used in a unique word clock, and even turned into a folding circuit sculpture.

Build Your Own Vacuum Chamber For Degassing And More
» ‎ Hack a Day

A vacuum chamber can be a useful thing to have around the shop. It can be used for all manner of purposes, from science experiments to degassing paints and epoxies. They’re not something you’d find in every workshop, but never fear – you can always build one from scrap you’ve got lying around! (YouTube video, embedded below.)

[VegOilGuy] begins the build with a simple plywood box, which gets screwed together and then tarted up with bodyfiller and paint. This helps to make the box airtight, as well as improving the aesthetics. A slot is then cut in the lid, and then filled with an excessive amount of silicone sealant. A flat plate covered in aluminium foil is placed on top, and the silicone is left to cure for several days.This is used to create a flat sealing surface for the lid to be placed on later.

Once the seal is complete, it’s a simple plumbing job to finish the chamber. [VegOilGuy] does a great job of demonstrating copper soldering and the proper way to install the necessary taps and check valves. Combined with an electric pump, the vacuum chamber passes its tests with flying colors, completely ruining some marshmallows in the process.

With a few dollars spent online for the special bits, it’s a build that any handy maker could throw together in a weekend. You can always go another route, though – like using an old fridge compressor to get the job done.

[Thanks to Keith O for the tip!]

This Bike Pump Now Sucks
» ‎ Hack a Day

Pulling a vacuum is something every proud maker must do once in a while. Whether you’re degassing epoxy or vacuum forming parts, you’ll need a reliable pump to get the job done. [drcrash] has just the guide to help – on how to convert a regular handpump to vacuum duty. (Video embedded after the break.)

[drcrash] recommends starting with a Slime brand 2060-A pump or similar. It’s a basic hand pump, with no pressure gauges or other frills to get in the way. It’s also got a strong steel shaft that can hold up to repeated use. You’ll also need some tubing and a check valve to get the job done.

The basic concept is to reconfigure the pump to suck air out of things rather than blowing it into them. By removing the original check valve and installing one in the opposite direction, and reversing the pump’s piston, it’s possible to pull good vacuum without breaking a sweat. [drcrash] reports that it’s possible to go up to 11 psi below atmospheric with this setup, which is plenty for a wide range of applications. If you need to go further, you can try building your own turbomolecular pump instead.

Faced with this problem, [create] came up with an ingenious solution to help move long and heavy objects without outside assistance.

The build starts with a regular F-clamp – a familiar tool to the home woodworker. The clamp is old and worn, making it the perfect candidate for some experimentation. First off, the handle is given a good sanding to avoid the likelihood of painful splinters. Then, …read more

The one that [Made in Poland] chose to sacrifice was particularly nasty and greasy, but after popping off the pulley, the treasure within was revealed: the large, ring-shaped clutch electromagnet. Liberated from the compressor, the electromagnet was attached to a small frame holding a …read more

Box Joint Jig Does Barcodes
» ‎ Hack a Day

Woodworking is the fine art of turning dead tree carcasses into precision instruments. That means breaking out the saws and chisels and making many, many precise cuts over and over. If you have a table saw, every problem becomes a piece of wood, or something like that, and we’ve seen some fantastic jigs that make these precision cuts even easier. We’ve never seen something like this, though. It’s a box joint jig for a table saw, it’s automated, and it puts barcodes on boxes.

[Ben] built this box joint jig a few years ago as a computer-controlled device that slowly …read more

A Sneak Peek At The TS100 Soldering Iron’s Younger Sibling
» ‎ Hack a Day

Many readers will be familiar with the TS100 soldering iron, a lightweight and powerful tool with an integrated temperature controller in its handle based upon an STM32 microcontroller. As an iron it’s a joy to use, it has hackable code, and it has become a firm favourite within our community. There have been rumours of a TS100 stablemate for some time now, with the model number being touted as a TS200 and with it being said to be USB-C powered. But beyond those tidbits, until now there has been not a lot to go on.

Bluefog 0.0.2
» ‎ Packet Storm Security Misc. Files

Bluefog is a tool that can generate an essentially unlimited number of phantom Bluetooth devices. It can be used to test Bluetooth scanning and monitoring systems, make it more difficult for attackers to lock onto your devices, or otherwise complicate the normal operation of Bluetooth devices. Technically, Bluefog can work with just one Bluetooth adapter, but it works much better when you connect multiple adapters. Up to four radios are currently supported simultaneously.
