You may think that cathode ray tube (CRT) TVs and monitors have gone the way of the dinosaur, but you’d be wrong. Many still have them for playing video games at home or in arcades, for vinta…

When it comes to logic technologies, we like to think we’ve seen them all here at Hackaday. But our community never ceases to surprise us with its variety and ingenuity, so it should be a sur…

When engineers are designing buildings, bridges, or other large construction projects, a lot of thought is given to the environment. Some of these considerations might seem obvious, like designing …

We’ve been seeing an influx of repurposed 3D printers recently. Thrifty hackers have been leveraging cheap 3D printers as a way to bootstrap their builds, on everything from laser engravers t…

Everyone’s heard of the “black box”. Officially known as the Flight Data Recorder (FDR), it’s a mandatory piece of equipment on commercial aircraft. The FDR is instrumental …

The last challenge of The Hackaday Prize has ended. Over the past few months, we’ve gotten a sneak peek at over a thousand amazing projects, from Open Hardware to Human Computer Interfaces. T…

There was a time, not so long ago, when hype for desktop 3D printing as so high that it seemed you could print anything. Just imagine it, and your handy dandy magical 3D printer could manifest it i…

Exploiting the resources of the rock-strewn expanse of space between Mars and the outer planets has been the stuff of science fiction for ages. There’s gold in them ‘thar space rocks, o…

It isn’t a unique idea, but we liked [Eric Wiemers’s] take on the classic animated skull for Halloween. In addition to showing you the code and the wiring, the video spends some time di…

The first thing you probably asked yourself when learning how to lay out PCBs was “can’t the computer do this?” which inevitably led to the phrase “never trust the autoroute…

The Hackaday Prize is the greatest hardware competition on the planet. It’s the Academy Awards of Open hardware, and over the past few months we’ve challenged makers and artists to crea…

They say the only difference between a violin and a fiddle is the way you play it. If that’s so, this modular violin will need a new name, since it can be broken apart and changed in ways tha…

Here at Hackaday, we have a soft spot for security dongles. When a new two-factor-authentication dongle is open source, uses USB and NFC, and supports FIDO2, the newest 2FA standard, we take notice…

Another day, another CVE (Common Vulnerabilities and Exposures). Getting a CVE number assigned to a vulnerability is a stamp of authenticity that you have a real problem on your hands. CVE-2018-109…
