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…

Some of the earliest automobiles weren’t powered by refined petrochemicals, but instead wood gas. This wood gas is produced by burning wood or charcoal, capturing the fumes given off, and bur…

Part of what makes flamethrowers fun is their inherent danger. This is what makes a lot of things fun, though, from snowboarding to skydiving to motorcycle riding. As with all of these sensible hob…

By the early 20th century, naval warfare was undergoing drastic technological changes. Ships were getting better and faster engines and were being outfitted with wireless communications, while nava…

In this day and age, we are truly blessed as far as the electronics hobby is concerned. Advanced modules such as gyros and motor controllers are readily available, not just as individual parts, but…

For this week’s Hack Chat, we’re going to be discussing generating analog video for visual synthesis. What’s on the front porch? Our guest for this week’s Hack Chat will be …

[Moritz Simon Geist]’s experiences as both a classically trained musician and a robotics engineer is clearly what makes his Techno Music Robots project so stunningly executed. The robotic ele…

The wonders of 3D printing don’t stop coming. Whether it’s printing tools on the International Space Station, printing houses out of concrete, or just making spare parts for a child&#82…

Most CNC workflows start with a 3D model, which is then passed to CAM software to be converted into the G-code language that CNC machines love and understand. G-code, however, is simple enough that…

The United States has announced plans to withdraw from a 144-year postal treaty that sets lower international shipping rates. The US claims this treaty gives countries like China and Singapore an u…

ICs have certainly changed electronics, but how much do you really know about how they are built on the inside? While decapsulating and studying a modern CPU with 14 nanometer geometry is probably …

There’s a lot going on our virtual spaces, and anyone with a smart phone can attest to this fact. There are pop-up notifications for everything you can imagine, and sometimes it’s possi…

Science fiction is usually couched in fact, and it’s fun to look at an iconic computer like HAL 9000 and trace the origins of this artificial intelligence gone wrong. You might be surprised t…

Behold the wondrous complexity of the human hand. Twenty-seven bones working in concert with muscles, tendons, and ligaments extending up the forearm to produce a range of motions that gave us ever…

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…
