For several years, hackers have been exploring inertial measurement units (IMUs) as cheap sensors for motion capturing. [Ivo Herzig’s] final Diploma project “Bewegungsfelder” take…

Here’s a question for you all: how will you know when you are no longer young? When you fall out of love with contemporary popular music perhaps, or start to find the idea of a cruise holiday…

Making beautiful things from epoxy and wood happens to be [Peter Brown’s] area of expertise. He was recently quested with reverse engineering the ring design of the Canadian manufacturer secr…

We’ve seen tiny microcontroller-based computers before, but nothing like this. Where the usual AVR + display + serial connection features BASIC, Forth, or another forgotten language from the …

Beautifully documented, modular, and completely open-source, this split flap display project by [JON-A-TRON] uses 3D printing, laser cutting and engraving, and parts anyone can find online to make a...

The Internet of Things is garbage. While the most visible implementations of the Internet of Things are smart lights that stop working because the company responsible for them folded, or smart thermos...

Newton's Cradle is thought of as the most elegant of executive desk toys. But that 20th-century dinosaur just got run off the road as [Ben Katz]'s Furuta pendulum streaks past in the fast lane, flip...

Flash memory is the king today. Our microcontrollers have it embedded on the die. Phones, tablets, and computers run from flash. If you need re-writable long term storage, flash is the way to go. I…

Hardware hackers are always looking for devices to tear apart and scavenge from. It’s hardly a secret that purchasing components individually is significantly more expensive than the minuscul…

Rearchers of the Harvard Medical School built a 2 feet by 4 feet (61 x 122 cm) large petri-dish to visualize the evolution of bacteria. Their experiment induces mutations in E. coli bacteria by exp…

A while back, [Kyle] wanted to grow gourmet mushrooms. The usual way of doing this is finding a limestone cave and stinking up half the county with the smell of manure. Doing this at home annoys fa…

[Alex Zaikin] made a modern reproduction of an early-80s Soviet hobbyist home computer. Although the design was open, indeed it was published in "Radio" magazine, the project was a mammoth undertaking...

A while back, [heypete] needed to get a GPS timing receiver talking to a Raspberry Pi. The receiver only spoke RS-232, and the Pi is TTL level serial. [Pete] picked up a few RS-232 to TTL conversion b...

A decade ago, RC transmitters were clunky, expensive and PCM. A decade before that, everything was analog. Now, RC transmitters are completely digital, allowing for hundreds of aircraft to take to th...

The ESP32 is looking like an amazing chip, not the least for its price point. It combines WiFi and Bluetooth wireless capabilities with two CPU cores and a decent hardware peripheral set. There wer…

There was a time when building something yourself probably meant it didn't look very much like a commercial product. That's not always a bad thing. We've seen many custom builds that are nearly works ...

Last week, we had a look at a carbon-infused PETG filament. This week, I’d like to show you two composites based on a more common thermoplastic in 3D printing: ABS. Among a whole lot of other…

How do you measure the value of an unknown inductor? If you have an LCR bridge or meter, you are probably going to use that. If not, there are many different techniques you can use. All of them rel…

Although this sort of work is usually reserved for KansasFest and other forums for highly technical and very skilled Apple enthusiasts, [John Brooks]'s release of a new version of the ProDOS operating...

For all the complexity involved in driving, it becomes second nature to respond to pedestrians, environmental conditions, even the basic rules of the road. When it comes to AI, teaching machine lea…
