We know that most of you will have no reason to ever make a miniature X-ray tube. However, we also know that many of you will find this video mesmerizing like we did. [Glasslinger] does a fantastic job of explaining the entire process of creating the mini x-ray tube from, procuring the uranium glass and [...]

[Eric Gregori] sent in an article he wrote for EETimes to introduce the concepts behind computer vision to the masses. As a nice little bonus, [Eric] included a VMware image containing Ubuntu and all the packages and examples necessary to write your own OpenCV apps. There’s a ton of awesome stuff you can do with [...]

We all know that our precious cruisers/warships/assets can not fall into the wrong hands, and what better way to assure that information security than incorporating a self destruct button into the design? While the general premise is simple enough the only real way to make sure some crazy space-virus can’t infect your captain and force [...]

If you’ve ever looked at one of [Todd Harrison’s] teardown or how-to videos closely, you would likely notice that his work bench looks like a standard hacker workspace. While we all try to keep our work areas clear of clutter, it’s not uncommon for components to pile up, cords to tangle, and things to get [...]

Little, no name, 1.5 inch LCD photo key-chains are all over the place for practically nothing. Not too surprisingly these things do not vary much in the parts that they use, some flash ram, a little lipo battery and a 16 bit color LCD. Wanting to find a way to reuse that LCD [Simon] Has [...]

Part of the fun with old computers is playing some old school games, and while you could play them with a keyboard it is much more fun with a joystick. You can get old joysticks all day long on auction sites, but you have to watch out. Some are digital, which wont work for many [...]

If you’ve been reading Hack a Day for long enough, you know about our infatuation with stepper motors. These precious little devices put the oomph into our CNC routers, 3D printers, robots, and other miscellaneous projects. Steppers aren’t your run-of-the-mill motors, though. [Steaky] posted a great introduction to stepper motors that lets you hit the [...]

The folks over at Toymaker Television have put together another episode. This time they’re looking at bridge rectifiers and how they’re used in AC to DC converters. This is a simple concept which is worth taking the time to study for those unfamiliar with it. Since Alternating Current is made up of cycles of positive [...]

Eminent steampunker [Jake Von Slatt] wrote a small article on etching candy tins for The Steampunk Bible, but the limited space available in the book didn’t allow for a full exposition. To make amends for his incomplete tutorial, he posted this walk through to compliment the Bible’s article. The process is very similar to the [...]

Our friend [Jeri] tipped us off about this cool video on youtube where the author makes his own “transparent” PCB’s using some nontraditional materials.

This week we are continuing on with our multi-part series where [Jack] shows you how to use Eagle CAD. This video continues where last week’s video left off by showing how to create a custom part and how to use the schematic editor. If you haven’t seen last week’s video, you can find it here. [...]

Although many might not know it, electroluminescent materials use high voltage, and thus qualify for our featured topic. Many may assume that these sheets work in the same way as LED lights, using low-voltage DC power. This, however, is not the case, as they need around 100 volts of AC current to allow them to [...]

Continuing on with our high-voltage theme, today we have a page describing Marx generators by [Grenadier]. Marx generators are devices that produce pulses of very high voltage with fast rise times. For most of us, that means that they can make neat sparks. For the more serious types out there, that also means that they [...]

Hackaday headquarters has recently been overrun by techno-groupies hanging around outside so we decided to take some measures to discourage that. A word of warning though, if last week’s video ruffled your feathers then you probably shouldn’t watch this one. In this video [Jack] shows you how to create a stun glove using a disposable [...]

[Chris] is at it again and this time he has put together a tutorial rounding off his animatronic face by actuating the mouth. His tutorial covers two different styles of robot mouth: an LCD mouth which dims to imply actuation and a servo articulated flap. [Chris] covers all the aspects of each mouth type, from [...]

When [Kerry] wanted to measure some very small resistances very accurately he did not want to fork out the big bucks for a high end multimeter or a mico-ohmmeter, so he decided to build one himself. Measuring resistance is a simple enough concept, it directly implements Ohms law (V=IR). The problem with very small resistances [...]

[Dino Segovis] wrote in to tell us about his “hack”, making an AB Audio Amplifier. The advantage of this particular amp is that the transistors never turn off, which would cause distortion.

[desimon] had a wanted to use some accelerometer chips, but their 3x3mm 16-VFQFN packages made it pretty darn hard to solder by hand.

There is a plethora of electronics tutorials scattered about online. Sometimes it can be hard to separate the good ones from the bad, and the enlightening from the misinformed.

[Armin Tamzarian’s] local library recently started lending eBooks via the OverDrive Media Console system.

[Chris] sent us this fantastic tutorial, introducing beginners to H-bridge motor drivers.

[Emily Daniels] has been teaching interactive electronics workshops geared towards children for some time now, recently holding a session that demonstrated how batteries work in a pretty novel fashion.

Jeff is a huge music fan, and like many of us likes old technology, so it seemed a bit silly (to him) that he did not have a turn table. His dad had a spare in the basement. A neat old Braun model from the 1970′s that was broken. Opening the unit up he found [...]

Arguably, Microchip’s PIC microcontrollers do not get enough posts here. One of the drawbacks for some of us is that Linux support for PICs is not very well known.

For those unaware, the little acronym above stands for Do-It-Yourself-Direct-To-Garment printing. In layman’s terms, printing your own shirts and designs. Commercial DTGs can cost anywhere from $5,000 to $10,000 which for the hobbyist who only wants a few shirts is ridiculous. So you would think this field of technology would be hacked to no end, [...]
