Wiring into the joystick is a quick and easy way to hack in custom control to a wheelchair. Building robots can be fun, and remains a popular pastime among many in the hacker and maker set. However the hardware side of things can be daunting. This is particularly the case for those attempting to build […]
Last month we featured an interesting project from Hackaday.io that was essentially trying to recreate the iconic Blackberry form factor for use with Adafruit’s line of Feather development boards. This would let you drop in modules for everything from LTE to packet radio, opening up a nearly limitless possibilities for handheld hacking. The only problem […]
For his Hackaday Prize entry, [Martin] is building an Open Source Multimeter that can measure voltage, current, and power. It’s an amazing build, and you too can build one yourself. The features for this multimeter consist of voltage mode with a range of +/-6V and +/-60V. There’s a current mode, basically the same as voltage, […]
What looks like something famous, is much smaller, and is embroiled in a web of cold war cloak-and-dagger intrigue? It sounds like the answer could be Mini-Me from the Austin Powers movies, but we were actually thinking of the D-21 supersonic spy drone. Never heard of it? It didn’t have a very long service life, […]
People take their tabletop games very, very seriously. [Andrew Lauritzen], though, has gone far above and beyond in pursuit of a fair game. The game in question is Star War: X-Wing, a strategy wargame where miniature pieces are moved according to rolls of the dice. [Andrew] suspected that commercially available dice were skewing the game, and […]
By and large, automakers have spent much of the last century trying to make cars quieter and more comfortable. Noise from vehicles can be disruptive and just generally annoying, so it makes sense to minimise it where possible. However, the noise from the average motor vehicle can serve a useful purpose. A running engine acts […]
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 […]
Maybe you’ve heard of a TV show called The Simpsons. Steamed Hams make a one-gag appearance in an unforgettable luncheon where Principal Skinner poker-faces his way out of a disaster with Superintendent Chalmers. Meanwhile, over on imgur, [Agumander] has put a black and white screencap from Steamed Hams in a printed circuit board. The memory […]
Some of us are guilty of picking up questionable hardware from garage sales, fleamarkets, and well-meaning relatives. There is a balance between turning down a good investment and hoarding, and if we figure out how to tell the difference you will be the first to know. [Clem Mayer] may start on the side of unwise […]
If you like nitpicking around C code and generated assembly language — and we’ll admit that we do — you shouldn’t miss [Scaramanga’s] analysis of what’s known as Kernighan’s trick. If you haven’t heard of the trick, it’s a pretty efficient way of counting bits. Like the Wheatstone bridge and a lot of other things, […]
