Looking for something a bit more from your Raspberry Pi? Tired of the usual console and arcade games? Eltech’s Exagear Desktop is a virtual machine that runs on your Raspberry Pi and allows y…

A few weeks back, we talked about the no-nos of running I²C over long wires. For prototyping? Yes! But for a bulletproof production environment, this practice just won’t make the cut. This mo…

If you're looking for a high entertainment value per byte of code, [Nardax] has you covered with his wearable spellcasting controller. With not much effort, he has built a very fun looking device, pro...

The advance of electronic technology has been closely followed by the medical community over the past 200 years. Cutting edge electronics are used in medical imaging solutions to provide ever great…

Pong may not be much anymore, but it’s the granddaddy of all video games, and there’s still a lot to learn by studying its guts. And what better way to do that than by having it all lai…

This is about the time of the year you realize you aren’t going to keep all of those new year’s resolutions you made. However, if one of them was to learn VHDL and FPGAs, you might be i…

Getting into machining is hard. From high-speed seel versus carbide to "old US iron" versus "new Asian manufacture" to simply choosing which drill bits to buy, many hard decisions must be made before ...

In the open-source world, there are two main choices for PCB design: KiCad and gEDA. But if you're tired of the boring Hershey fonts telling you which resistor is which, or if you need to comply with ...

It’s not often that we are shown an entirely new class of test equipment here at Hackaday, so it was with some surprise that we recently received the new O-scope Mayer offering. If your most …

The wheel is a revolutionary invention — as they say — but going back to basics sometimes opens new pathways. Robots that traverse terrain on legs are on the rise, most notably the Bost…

At Hackaday, we’re tapped into Hacker Culture. This goes far beyond a choice of operating system (Arch Linux, or more correctly, ‘Arch GNU/Linux’, or as I’ve recently taken …

If you walk the halls of audiophilia, you may be aware that there has been a huge amount of work put in to software designed to clean up older audio recordings without compromising the quality of the ...

 

There are innumerable password hacking methods but recent advances in acoustic and accelerometer sensing have opened up the door to side-channel attacks, where passwords or other sensitive d...

We feature a lot of clocks here on Hackaday, and lately most of them seem to be Nixie clocks. Not that there’s anything wrong with that, but every once in a while it’s nice to see somet…

One of the biggest problems for prosthetic users is feel. If you’ve ever tried to hold a pen and write with a numb hand, you’ve realised how important feedback is to the motor control e…

A water pump is one of those items that are uncommonly used, but invaluable when needed. Rarer still are cordless versions that can be deployed at speed. Enter [DIY King 00], who has shared his build ...

One reason we really like [Rulof]'s hacks is that he combines the most unlikely things to create something unexpected. This time he makes a fast-moving loop of cotton string undulate in time to music....

Today, if you want to teach kids the art of counting to one, you're going to drag out a computer or an iPad. Install Scratch. Break out an Arduino, or something. This is high technology to solve the s...

If you’re at all into medical hacks, you’ve doubtless noticed that the medical industry provides us with all manner of shiny toys to play with. Case in point is a heart-monitoring IC th…

If you are a certain age, MOS6581 either means nothing to you, or it is a track from Carbon Based Lifeforms. However, if you were a Commodore computer fan 35 years ago, it was a MOS Technologies SI…
