We think of electrolysis as a way to split things like water into oxygen and hydrogen using electricity, but it has a second meaning which is to remove hair using electricity. An electrologist inse…

Reddit user [barbarisch] thought his computer desk was a bit boring, so he came up with a cool project to spice it up: A Tron-inspired computer desk with embedded LED strips! [Barbarisch] took a ba…

What happens when you come across a mysterious, partially populated circuit board in the Huaqiangbei electronics market in Shenzhen? If you’re [Scotty Allen], the only answer is to make your …

Blockchains claim to be public, distributed, effectively immutable ledgers. Unfortunately, they also tend to get a little bit huge – presently the Bitcoin blockchain is 194GB and Ethereum weighs in…

Remote administration of machines is a very useful tool for all manner of commercial, industrial, and home applications. Now, it’s available for claw machines, too – thanks to [Code You…

Somewhere, in a storage closet used by every computer science or engineering program, is a robot arm. It’s there, you’ve probably never seen it, but it’s there. Originally, this h…

In the first part of this series, we covered the basics of pointers in C, and went on to more complex arrangements and pointer arithmetic in the second part. Both times, we focused solely on pointe…

Right now, we’re running the greatest hardware competition on the planet. The Hackaday Prize is the Academy Awards of Open Hardware, and we’re opening the gates to thousands of hardware…

Anyone who’s ever tried setting up a workbench in a tight space knows the struggle: you want to have all your test equipment and tools out and within arm’s reach, but you just don&#8217…

Even if you aren’t a tube aficionado, you can’t help but be mesmerized by the blue glow inside a mercury vapor rectifier when it operates. It looks less like early 20th century tech and…

A can of soda costs about half a dollar, and once you’re done with the sugary syrup, most cans end up in the trash headed for recycling. Some folks re-use them for other purposes, but we&#821…

BACAR — Balloon Carrying Amateur Radio — is just what it sounds like. A high-altitude balloon carries experiments and communicates via amateur radio. [ZR6AIC] decided to fly a payload i…

Gesture-enabled controls mean you get to live out your fantasy of wielding force powers. It does, however, take a bit of hacking to make that possible. Directly from the team at [circuito.io] comes…

A few days ago we brought you news of [Sam Zeloof]’s amazing achievement, of creating the first home-made lithographically produced integrated circuit. It was a modest enough design in a simp…

OctoPrint is arguably the ultimate tool for remote 3D printer control and monitoring. Whether you simply want a way to send G-Code to your printer without it being physically connected to your comp…

3D printing makes it easy to produce complex geometries, but the fused deposition methods generally create parts with poor surface finish, largely due to the layers being highly visible in the fini…

Hone your skills at basic robot building. You’re invited to join Hackaday for a Beginner Robotics Workshop on Saturday, May 12. For this workshop we’re pairing up with FIRST robotics me…

If you got your start in electronics sometime after 1980 your first project might well have been to light up an LED. Microcontroller projects often light up an LED, too, and a blinking LED is somet…
