Let’s say you’re working on a project, and you need a microcontroller. Which chip do you reach for? Probably the one you’re most familiar with, or at least the one whose programme…

As the saying goes, hindsight is 20/20. It may surprise you that the microchip that we all know and love today was far from an obvious idea. Some of the paths that were being explored back then to …

Almost two years ago, a research team showed that it was possible to get fine motor control from cheap, brushless DC motors. Normally this is not feasible because the motors are built-in such a way…

When astronaut Dr. Peggy Whitson returned from space earlier this year, it was a triumphant conclusion to a lifelong career as a scientist, explorer, and leader. Whitson is a biochemist who became …

Face it — you want a reflow oven. Even the steadiest hands and best eyes only yield “meh” results with a manual iron on SMD boards, and forget about being able to scale up to prod…

Something you learn when you spend a good portion of your day trolling the Internet for creative and unique projects is that “Why?” is one question you should always be careful about as…

FDM 3D prints might be coming home this holiday as seasonal ornaments, but with a few tweaks, they may even stand up to the tests of the real world as functional prototypes. Heat-Set inserts are on…

Pixium Vision, a French company, has received the approval to begin in-human trials of a miniature wireless sub-retinal implant. Named PRIMA, the device may help those with advanced dry age-related…

In Western countries in the early 1980s, there was plenty of choice if you wanted an affordable computer: Apple, Atari, TRS-80, Commodore and Sinclair to name a few. But in communist-ruled Romania,…

After a year away from YouTube, the ever-energetic [Styropyro] has returned with whiteboard in hand to remind us just how little we actually know about lasers. In the last month he’s really h…

A team of college hackers was disappointed with the selection of secure purses available. Nearly every purse on the market is attractive, secure, or neither so they are designing their own security…

If you were to ask a random Hackaday reader what their most fundamental piece of electronic test equipment was, it’s likely that they would respond with “multimeter”. If you asked…

We’ve seen industrial robotic arms in real life. We’ve seen them in classrooms and factories. Before today, we’ve never mistaken a homemade robotic arm for one of the price-of-a-n…

We just got the shipment of hot Hackaday Superconference badges in our hands yesterday, and they’re frankly awesome. Due to great manufacturing partners and a fantastic design by [Mike Harris…

I’ve got virtual circuits on the mind lately. There are a myriad of tools out there that I could pick up to satisfy this compulsion. But the one I’m reaching for is Minecraft. I know wh…

We’ve seen our share of stepper motors making music, but [Tanner Tech’s] key-tar takes it to a whole new level. Incorporating an acoustic drum to accentuate the stepper motor sounds and…

[Super 73] make electric scooters, and they made some Star Wars Speeder Bikes with a twist for Halloween; adding some mirrored panels around the bottoms of the bikes made for a decent visual effect…

Adafruit has long been the undisputed ruler of the smart LED product, with their WS2812B (NeoPixel) and APA102C (DotStar) product lines dominating due to the robust assortment of sizes and form fac…

Ok, we’ll stipulate it right up front: this isn’t a hack. But you have to admit, it would make a fine starting point for a truly epic one. Robby the Robot — the robot from the 195…

What do you get when you put an ultra-bright LED in the palm of a glove, and strobe it controlled by an accelerometer? A Time Control Glove! In creator [MadGyver]’s own words, it’s &#82…
