There’s some interesting technology bundled into this energy harvesting wristwatch. While energy harvesting timepieces (called automatic watches) have been around for nearly 240 years, [bobricius] …

Even with all the hamster wheel trackers out there (and on this site) there’s room for improvement. [Bogdan] upgraded his hamster wheel from an Arduino and datalogging shield to an ESP32, and unlea…

Remember the Raspberry Pi Sense Hat? Originally designed for a mission to the International Space Station, the board has quite a few sensors onboard as well as an 8×8 RGB LED matrix. What can …

We know, we know. They are bad for you. You shouldn't start, but some people do love a cigar. And a fine cigar is pretty particular about drying out. That's why tobacconists and cigar aficionados sto...

Holocrons are holographic data storage devices used in the Star Wars universe by both Jedi and Sith as teaching devices or for storing valuable information. After the fall of the Jedi, they became ra...

One of the biggest trends in whatever market 'Maker' stuff belongs to is the Legofication of electronics. Building electronics is hard, if you haven't noticed. Anything that turns transmission lines, ...

Doctors use RF signals to adjust pacemakers so that instead of slicing a patient open, they can change the pacemakers parameters which in turn avoids unnecessary surgery. A study on security weakne…

Deep in the heart of a Chinese click farm — and probably used by the company your company hired to build an ‘app’ — is a magical device. Call it a Beowulf Cluster of Phones.…

Off the hop, we love portable consoles. To be clear, we don’t just mean handhelds like the 3DS, or RetroPie builds, but when a maker takes a home console from generations past and hacks a chi…

There's a harsh truth underlying all robotic research: compared to evolution, we suck at making things move. Nature has a couple billion years of practice making things that can slide, hop, fly, swim...

With procedural content generation, you build data algorithmically rather than manually — think Minecraft worlds, replete with all the terrains and mobs you’d expect, but distributed di…

Wouldn’t it be nice if you had a flying machine that could maneuver in any direction while rotating around any axis while maintaining both thrust and torque? Attach a robot arm and the machin…

When MITS introduced the Altair 8800–about 43 years ago–it spawned the first personal computer clone: the IMSAI 8080. The clone had several improvements and MITS had difficulty filling …

Prolific hacker [kodera2t] is working on his own "ESP32 monster board" dev board for the still-newish ESP32 WiFi module. His board has everything: Ethernet, OLED, LiPo, and even CAN-bus. But all that ...

Boeing and DARPA are building a spaceplane. Right now it's only a press release and a few concept images, but it looks like this is an air-launched system kind of like a Tristar/Pegasus, only much hig...

A standard early electronics project or kit has for many years been the construction of a small broadcast transmitter with enough power to reach the immediate area, but no further. These days that …

[EvilTim] dug deep into a classic system to finally give the Game Gear a proper video output.  The Game Gear was Sega’s answer to Nintendo’s Gameboy. Rushed to market, the Game Gear reu…

Chess has been around for an awfully long time, automobiles less so. However, there's no reason the two can't be combined, like in this chess set fashioned from automotive components.

The project w...

[Michael Brandl] got to visit the Milka chocolate factory in Bludenz, Austria and was inspired to build this simulation of the production process for the LEGO world 2017 event in Copenhagen.

The pr...

If we cast our minds back to the early years of the transistor, the year that is always quoted is 1947, during which a Bell Labs team developed the first practical germanium point-contact transistor. ...
