It is mind-boggling when you think about the computing power that fits in the palm of your hand these days. It wasn’t long ago when air-conditioned rooms with raised floors hosted computers f…

When a project has outgrown using a small microcontroller, almost everyone reaches for a single-board computer — with the Raspberry Pi being the poster child. But doing so leaves you stuck wi…

It has never been easier to put a microcontroller and other electronics into a simple project, and that has tremendous learning potential. But when it comes to mechanical build elements like enclos…

The patience and precision involved with drawing geometric patterns in sand is right up a robot’s alley, and demonstrating this is [rob dobson]’s SandBot, a robot that draws patterns th…

We all know the drill when buying a digital oscilloscope: buy the most hackable model. Some choose to void the warranty right away and access features for which the manufacturer has kindly provided…

Virtual Reality (VR) and Actual Reality (AR) often don’t mix: watch someone play a VR game without seeing what they see and you see a lot of pointless-looking flailing around. [Nerdaxic] may …

A computer is, at its core, just a bunch of transistors wired together. Once you have enough transistors on a board, though, one of the first layers of abstraction that arises is the Arithmetic Log…

If you were a youth in the 90s, odds are good that you were a part of the virtual pet fad and had your very own beeping Tamagotchi to take care of, much to the chagrin of your parents. Without the …

Telling time by using the current position of the sun is nothing revolutionary — though it probably was quite the “life hack” back in ancient times, we can assume. On the other ha…

A robotic arm is an excellent idea if you’re looking to get started with electromechanical projects. There’s linkages to design, and motors to drive, but there’s also the matter o…

When I started working in a video production house in the early 1980s, it quickly became apparent that there was a lot of snobbery in terms of equipment. These were the days when the home video mar…

Trash is relative. When my coworker accidentally lit an ABS-barbecue inside the company laser cutter, he made trash. The wreckage was headed for the dump, but I managed to save it and pass it on to…

Do you talk to your alarm clock? I do. I was recently in a hotel room, woke up in the middle of the night and said, “Computer. What time is it?” Since my Amazon Echo (which responds to …

The Triforium is a public art installation in Los Angeles, weighing 60 tons and standing six stories tall. Built in 1975, it was designed to combine light and sound, all under the control of comput…

In the 1970s, the Soviet Union decided to dig a hole for science. Not just any hole, the Kola Superdeep Borehole reached a depth of over 12 kilometers, the deepest at the time and the second deepes…

Wiring is one of those things that we’ve all had to do on a project, but probably didn’t give a lot of thought to. It’s often the last thing that happens during the build, and alm…

Engineers, hackers, and makers can most certainly build a musical gadget of some kind. They’ll build synths, they’ll build aerophones, and they’ll take the idea of mercury delay l…

Back in the early days of Arduino proliferation (and before you ask, yes we realize there was a time before that too), wireless was a strange and foreign beast. IR communication was definitely a th…

If it’s stupid and it works, then it’s not stupid. There’s no better evidence of that than [Tobias]’ networking setup. He recently had to distribute Ethernet through a build…

We just wrapped up the Musical Instrument Challenge in the Hackaday Prize, and for most projects that meant replicating sounds made by humans, or otherwise making musicians for humans. There’…
