Hack a Day
[Matt] literally finds himself in a sticky situation. There’s an oil slick in his sump well. These wells work in conjunction with drain tiles to pump water away from the foundation of a house. Unfortunately the tar that was used to waterproof the outside of his foundation is also washing into the sump and gumming [...]

eBay isn’t only about counterfeit designer handbags and boxes of all-marshmallow Lucky Charms, sometimes there’s actually something useful for sale. [Matt] found a bunch of Chinese-made ARM development boards with integrated LCD displays on the ‘bay, but without a reliable toolchain, these boards – as cool as they are – are nearly useless. Thankfully, he figured [...]

With digital cameras in everything and film slowly disappearing from shelves, everyone loses an awesome way to learn about photography. Pinhole cameras allow anyone to build a camera from scratch and also learn about those crazy f-stops, exposure times, and focal planes that Instagram just won’t teach you. [Matt] put up a great tutorial for building your [...]

The signs on the front door might be a little small, but the space which AssentWorks and Skullspace inhabit is anything but. [Matt] takes us on a tour of the Winnipeg, Canada makerspace and hackerspace. The two spaces occupy one floor of the building but are partitioned for different purposes. AssentWorks, which is called a [...]

[Matt] wanted to have more control over his meat smoker so he built this advanced PID smoker controller. It uses the solid state relay seen in the bottom-right of this image to switch the smoker’s heating element. But all of the other goodies that are included add several features not usually found in these builds. [...]

Since the first time [Matt] saw an e-paper display, the idea of using it as a regularly updated, non real-time display consumed him. It really is the perfect platform for very readable calendars, agendas or, as [Matt] found out, a weather display. [Matt]‘s build uses a server to fetch and parse weather data and forecasts from NOAA. [...]

When you think of DIY hardware, genetic research tools are not something that typically comes to mind. But [Stacey] and [Matt]‘s OpenPCR project aims to enable anyone to do polymerase chain reaction (PCR) research on the cheap. PCR is a process that multiplies a specific piece of DNA a few million times. It can be used [...]

When [Matt] started building his multirotor helicopter, he was far too involved with building his craft than worrying about small details like how to actually control his helicopter. Everything worked out in the end, though, thanks to his homebrew RC setup built out of a USB joystick and a few XBees. After a few initial revisions [...]

[Matt the Gamer] loved his pair of Minimus 7 bookshelf speakers. That is until a tragic hacking accident burned out the driver and left him with a speaker-shaped paper weight. But the defunct audio hardware has been given new life as a single portable powered speaker. Now he can grab it and go, knowing that [...]

It’s possible that it was [Matt Meerian]‘s awesome pun that won us over, not his ultrasonic bicycle dog defense system, but that would be silly. [Matt] wanted an elegant solution to a common problem when riding a bicycle, dogs. While, obscenities, ammonia, water, pepper spray, and others were suggested, they all had cons that just [...]

[Matt and Jason Tardy], who make up the musical performance duo known as AudioBody, were recently featured on Make: explaining how they put on one of their trademark segments. The most popular portion of their show features color changing tubes of light which the pair spin and fling around not unlike a higher-tech version of [...]

[Matt Oppenheim] wrote in to share his work with us. He has been modifying the interfaces of electronics for the visually impaired. It started off with cassette decks. As [Matt] points out, many people who are visually impaired use cassettes for their audio books and newspapers. [Matt] added some touch sensors to the buttons so [...]

[Matt] sent in a set of YouTube videos walking us through his LEGO Mindstorms controlled brewery. [Matt] is using a RIMS brewing setup that recirculates and heats the mash to extract more starch from the grain. This results in a Maillard reaction in the mash and creates a richer, maltier flavor. To control his RIMS setup, [Matt] [...]

[Matt] emailed in to show us how he has improved his bubble display since the last time we saw it. If you recall from last time, he was having issues with the air pressure dropping when multiple bubbles were released, resulting in smaller bubbles. This time around, he has added an aesthetically pleasing air reservoir [...]

[Matt]‘s Descriptive Camera looks just like any other point and shoot camera, albeit a little more boxy and homemade-looking. It even works just like the Polaroids of yesteryear – snap a picture and in a few minutes you’ve got a reproduction in your hands. Unlike any other camera before, [Matt]‘s camera doesn’t give you an image. [...]

When [Matt] came across a small video camera made to fit onto a keychain, the first thing that came to mind is a time-lapse video throwie. Like the LED + coin cell battery + magnet we’ve seen we’ve seen before (and deployed…), [Matt]‘s video throwie would be deployed in interesting spots for a few days [...]

After he saw a ‘falling water display,’ [Matt] figured he could turn that idea on its head. He built a display that uses bubbles for pixels. Even though the build isn’t complete, we love the results so far. [Matt] began his build constructing a tall, thin water tank out of acrylic. Eight solenoids were mounted [...]

A media player based on an Arduino and SD card has been done to death several times over, but that doesn’t mean we can’t appreciate [Matt]‘s MSP430 audio player. It’s a very nice piece of work that supports a FAT16 file system and only takes up 54 bytes of RAM. To make his dream of [...]

A while back, [Matt] bought a few 8051 MCUs and tucked them away for a future project. He just found these fabulous little chips in a component drawer and decided it was time to figure these guys out. Eventually, [Matt] stumbled across this awesome resource for 8051 programming. The 8051 featured a still reasonably respectable 4k of [...]

Armed with four wingtip-mounted Sienar Fleet Systems L-s9.3 laser cannons and a SFS P-s5.6 twin ion engine, the TIE Interceptor has become the scourge of the Rebel fleet, nearly capable of out-running and out-maneuvering the beloved A-wings of Nomad Squadron. Because of [Matt]‘s tireless work, we can now visualize TIE Interceptors on approach with our targeting computers [...]

Transformers certainly have a tendency to increase the cost of any project, especially if you need a large transformer to get the job done. Microwave ovens are great sources of free transformers, though they are not always in the shape required for your next build. [Matt] put together three great tutorial videos covering the basics [...]

[Matt] noticed an overabundance of sous vide builds in the past week, so he decided to throw his Home made meat smoker into the ring. There’s not many things more delicious than a nice cut of smoked meat, and the fact that it’s very similar to the sous vide hacks we’ve seen is an added [...]

[Matt] entered himself in a pumpkin carving contest this year, even despite the fact that his artistic skills were a bit…lacking. He knew that he had very little chance of winning the contest unless he had a great gimmick to make his creation stand out, so he started brainstorming. [Matt] figured that since his design [...]

Who hasn’t thought about turning a 1950s slide projector into a digital projector? [Matt] did, but unlike most of us, he actually did it. [Matt]‘s friend [Angus] found an old, single-slide, sans-carousel slide projector in the trash. It’s a wonderful piece of ancient technology with a fabric insulated power cord and bakelite lamp socket. This [...]

Here’s a couple of clocks that use Arduino boards to control inexpensive clockworks. The concept is quite simple, and perhaps best outlined by [Matt Mets'] article on the subject. As it turns out, these clockworks are driven by a coil, forming a device that is quite similar to a stepper motor. If you solder a [...]

Today, with iPods that can hold entire music collections and cell phones that stream music from the Internet, the lowly cassette seems like an anachronism. [Matt] still has a cassette deck in his truck, but wanted Bluetooth connectivity for his stereo. The obvious solution was to stuff Bluetooth headphones into a cassette adapter. Audio cassette [...]

[Matt's] boat had a trim plate that could be adjusted by hand. The problem with this setup is that the trim angle of a boat changes as you speed up or slow down. Last year he never really went over 35 MPH because of this issue, but he set out to correct that by adding [...]

[Matt] over at Make came up with a way to send push alerts to his iPhone whenever his mailbox is opened. The electronics are just a switch mounted to the mailbox connected to an Arduino with an ethernet shield, but the interesting part of the build is the code. [Matt] got the Arduino WebClient to request [...]

Here’s a video projector that [Matt] hacked together. He needed a small and inexpensive solution to use with his R2D2 build. As you can see in the video after the break, it has no problem playing back the Princess’ distress call. But even if R2D2 is not one of the droids you’re looking for, we think [...]

This daughterboard lets [Matt Evans] drive a laptop LCD using a Beagleboard. Apparently the Beagleboard gained a VGA header when it moved to revision C but [Matt's] working with revision B4 which is why he had to do all of that ninja soldering with the blue wires. The driver board itself is a thing of [...]

[Matt] was looking for a challenge. Inspired by the machine gun setups on World War I planes he wanted to make a gun that can shoot between the blades of a spinning propeller. The original guns used an interrupter gear that synchronized machine gun firing with the engine mechanically. [Matt] set out to do this using [...]

[Matt] brought together a TV remote and cordless phone to add a locator system to the remote control. One of the best features of a cordless phone is the pager button on the base. When you press it the handset beeps until found. Matt gutted one and got rid of the unnecessary parts. He then cracked open [...]

[Matt] has mixed up a batch of two RFID reading door lock systems. While the “door lock” part of the setup has yet to come into existence, the “RFID reading” section is up and running. By using the Parallax RFID readers (for cheap, remember?) and an Arduino, [Matt] is able to parse an RFID tag, [...]

No, the picture above is not a store made steadicam. Rather, a CNC machined one by [Matt]. Interestingly, unlike most steadicams we’ve seen before the gimbal is not the main focus of the design though an aluminum machined gimbal would make us drool. The central idea is allowing for X and Y axis adjustment to [...]

PC-based USB oscilloscopes are fast becoming all the rage. [Matt Sarnoff’s] Terminalscope takes the reverse approach, adapting an oscilloscope into a full serial terminal. You may have seen something similar before in the Dutchtronix/SparkFun O-Clock, but [Matt’s] project goes one further by adding a PS/2 keyboard port for full bidirectional serial communication, and with much sharper display resolution to boot.

[Matt Bunting's] hexapod caught Intel’s eye (and their wallet). This coordinated little bot runs Ubuntu on an Atom Z530 processor, popular in netbooks like the Dell Mini 10, and uses a webcam to coordinate and monitor its motion. Intel picked up two of them from [Matt] to exhibit at trade shows. As you can see, [...]
