Through-hole resistors come on tape that we’re now calling bandoliers. Since [Spencer] is selling a boatload of his RC2014 backplane computer kits on Tindie, he’s been chopping up a lot…

A few years ago, we saw the reverse engineering of the Lattice iCE40 bitstream, opening the door to a completely Open Source development tool chain for FPGAs. This was an astonishing amount of work…

[Krazer], a post-doctoral researcher at MIT, loves him some lasers. When out of boredom one afternoon he hatched an idea for a laser projector, it grew until a few years later he wound up with this…

When you need to quantify the color of an object, you’ve got quite a few options. You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can bu…

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There …

As active devices go, it doesn’t get much simpler than a diode. Two terminals. Current flows in one direction and not in the other. Simple, right? Well, then there are examples with useful si…

When I presented myself at the SHACamp 2017 info desk bright and early on the first full day of the camp, I was surprised to find that I was to be assigned a volunteer along with my press badge. Be…

Everyone who wants a 3D printer probably already has one, and even laser cutters and CNC machines are making their way into garages and basements ’round the world. Pick and place machines are…

Chances are anyone who has an entry-level to mid-range smart TV knows that setting them up with your streaming account credentials is a royal pain. Akin to the days of texting on a flip phone, usin…

Clocks are a never-ending source of fascination to hackers. We get all kinds around here, from Steampunk Nixie clocks to retro cool flip clocks to clocks that don’t even look like clocks. But…

If you’ve never been a patient at a sleep laboratory, monitoring a person as they sleep is an involved process of wires, sensors, and discomfort. Seeking a better method, MIT researchers &#82…

The popularity of the ESP8266 WiFi module has a lot to do with its ability to inexpensively connect to the Internet. However, [hwhardsoft]’s stretch limousine environmental control system exp…

A mouse with malfunctioning buttons can be a frustrating to deal with — and usually a short leap to percussive maintenance. Standard fixes may not always last due to inferior build quality of…

A Vancouver man [007craft], also known as [Michael], posted a video on YouTube about his living in a storage locker to save money for an apartment. The small space meant he had to incorporate quite…

Last month I had the pleasure of creating a new piece of hardware for Tindie. [Jasmine], the queen bee of Tindie, and I designed, developed, and kitted three hundred Tindie badges in ten days leadi…

Chiptunes are the fantastic, bleeping musical renditions of the soundchips of retro consoles past. Performers of the art overwhelmingly favour the various flavours of Game Boy, though there are tho…

China is an amazing land of opportunity, and if you want to build anything, you can build it in Shenzhen. This city that was just a small fishing village a few decades ago has grown into a cyberpun…

It is nearly impossible to build any kind of hardware these days without at some point in the process dealing with China — Chinese suppliers, and so by extension Chinese culture. Difficulties…

For his Hackaday Prize entry, [Matt] is building a small kiln for melting metals and firing clay.  He’s making this kiln out of materials anyone can acquire — dirt and a bit of nichrome…

We see a lot of MAME cabinets and other gaming emulator projects here on Hackaday, but it’s not often that we see one the form factor of which so elegantly matches the ROM. [circuitbeard] con…
