Unless you have an incredibly well-stocked parts bin, it’s probably too late to build these spooky animated eyes to scare off the neighborhood kiddies this year. But next year… It&#8217…

Kahn — perhaps Star Trek’s best-hated villain — said: “Improve a mechanical device and you may double productivity, but improve man and you gain a thousandfold.” In fa…

Thirty years ago, we would be lucky if a computer could play audio. Take a computer from twenty years ago, and you’ll be lucky if it can play an MP3 in real-time. Now, computers can handle hu…

The Hackaday Superconference is this weekend and it’s the greatest hardware con on the planet. Tickets are completely sold out, but you can still get in on the fun by watching the livestream …

When you create a Thing for the Internet of Things, you’ve made a little computer that does a simple job and which probably has a minimal interface. But minimal interfaces leave little room f…

We’ve seen a variety of oddball 7-segment displays in the past, but this one uses a new material: both for the display and the mechanical mechanism that drives it; cardboard. Yup, the whole t…

There is a certain sense of accomplishment one gets when building their own tools. This is what [Alejandro Velazquez] was going for when he built his own soldering station. Sure you can get a decen…

We tend to think of elaborate electronic conference badges as something limited to the hacker scene, but it looks like the badgelife movement is starting to hit the big time. Now even the “bi…

Another day, another vulnerability. Discovered by [Kevin Backhouse], CVE-2018-4407 is a particularly serious problem because it is present all throughout Apple’s product line, from the Macboo…

Small I2C OLED displays are common nowadays, and thanks to the work of helpful developers, there are also a variety of graphics libraries for using them. Most of them work by using a RAM buffer, wh…

All of the tools you need to work with the FPGA Arduino — the Vidor — are now in the wild! We reported earlier that a series of French blog posts finally showed how all the pieces fit t…

We probably don’t have to tell the readers of Hackaday that LEGO isn’t just for kids; we’ve seen plenty of projects that live in an enclosure made of the multi-color bricks, and l…

The Hackaday Prize is almost over, and soon we’ll know the winners of the greatest hardware competition on the planet. A few weeks ago, we wrapped up the last challenge in the Hackaday Prize,…

If you’ve used a desktop 3D printer, you’re likely familiar with the concept of layer heights. Put simply: thicker layers will print faster, and thinner layers will produce better detai…

The theremin is, for some reason, what people think of first when they think of electronic musical instruments. Maybe that’s because it was arguably the first purely electronic musical instru…

Hybrid vehicles, which combine an eco-friendly electric motor with a gasoline engine for extended range, are becoming more and more common. They’re a transitional technology that delivers mos…

Spoiler alert: group of fun-loving French folks build an animal-or-human-powered merry-go-round that spins fast enough to fling all takers into the lake (YouTube, embedded below). Actually, that&#8…

[Dimitris Platis] works in an environment with a peer review process for accepting code changes. Code reviews generally are a good thing. One downside though, is that a lack of responsiveness from …

An oscilloscope is a handy tool for measuring signals of all kinds, but it’s especially useful if you want to measure something with a periodic component. Modern oscilloscopes have all kinds …

Robots that can dynamically reconfigure themselves to adapt to their environments offer a promising advantage over their less dynamic cousins. Researchers have been working through all the challeng…
