If you’re cutting metal in the workshop, you’re likely using a table-mounted cutoff saw, or perhaps a bandsaw for finer work. The power hacksaw is an unwieldy contraption that looks and feels very old fashioned in its operation. Despite the...

Word clocks are one of those projects that everyone seems to love. Even if you aren’t into the tech behind how they work, they have a certain appealing aesthetic. Plus you can read the time without worrying about those pesky...

There’s a line from the original Star Trek where Khan says, “Improve a mechanical device and you may double productivity, but improve man and you gain a thousandfold.” Joan Horvath and Rich Cameron have the same idea about improving education, particularly...

Eleven years ago, the Airbus A380 entered commercial service with Singapore Airlines. In the time since then it has become the queen of the skies. It’s a double-decker airliner, capable of flying 550 passengers eight thousand nautical miles. Some configurations...

What’s the buzz in the hackersphere this week? Hackaday Editors Elliot Williams and Mike Szczys recap their favorite hacks and articles from the past seven days. In Episode Six we cover an incredible reverse engineering effort Mike Harrison put in...

Regular readers of Hackaday have certainly seen the work of [Jeremy Cook] at this point. Whether you remember him from his time as a writer for this fine online publication, or recognize the name from one of his impressive builds...

“It wouldn’t happen that way in real life.” One of the most annoying habits of people really into the “sci” of sci-fi is nitpicking scientific inaccuracies in movies. The truth is, some things just make movies better, even if they...

When it comes to audio, the number of speakers you want is usually governed by the number of tracks or channels your signal has. One for mono, two for stereo, four for quadrophonic, five or more for surround sound and...

When you think of analog computing, it’s possible you don’t typically think of FPGAs. Sure, a few FPGAs will have specialized analog blocks, but usually they are digital devices. [Bruce Land] — a name well-known to Hackaday — has a...

There are applications you can download for your smartphone that can “roll” an arbitrary number of dice with whatever number of sides you could possibly want. It’s faster and easier than throwing physical dice around, and you don’t have to...

Most of use read and comment on Hackaday from the desktop, while we let our mind work through the perplexing compiler errors, wait for that 3D print to finish, or lay out the next PCB. But more and more people...

RISC-V is the new hotness, and companies are churning out code and announcements, but little actual hardware. Eventually, we’re going to get to the point where RISC-V microcontrollers and SoCs cost just a few bucks. This day might be here,...

Every year at Superconference, Editor-in-Chief Mike Szczys gets the chance to talk about what we think are the biggest, most important themes in the Hackaday universe. This year’s talk was about science and technology, and more importantly who gets to...

We all know CERN as that cool place where physicists play with massive, superconducting rings to smash atoms and subatomic particles to uncover secrets of matter in the Universe. To achieve this aim, they need to do a ton of...

Fritzing is a very nice Open Source design tool for PCBs, electrical sketches, and schematics for designers and artists to move from a prototype to real hardware. Over the years, we’ve seen fantastic projects built with Fritzing. Fritzing has been...

Lasers work by emitting light that is “coherent” in that it doesn’t spread out in a disorganized way like light from most sources does. This makes extremely focused beams possible that can do things like measure the distance from the...

There’s an old joke that all you need to fix TVs is a cheater, a heater, and a meter. If you don’t remember, a cheater was a cord to override the interlock on TVs so you could turn them on...

The gold standard for laser light shows during rock concerts is Pink Floyd, with shows famous for visual effects as well as excellent music. Not all of us have the funding necessary to produce such epic tapestries of light and...

Like many of us, [Matthew Wentworth] is always looking for a reason to build something. So when he found a 3D model of the “DF.9” laser turret from The Empire Strikes Back intended for Star Wars board games on Thingiverse, he...

One thing 3D printers excel at is being able to easily create objects that would be daunting by other methods, something that also allows for rapid design iteration. That’s apparent in [Canino]’s palm-sized, gatling-style, motorized 32-elastic launcher. The cannon has a...

Pivots for e-textiles can seem like a trivial problem. After all, wires and fabrics bend and flex just fine. However, things that are worn on a body can have trickier needs. Snap connectors are the usual way to get both...

What grew out of a university research project is finally becoming real silicon. RISC-V, the ISA that’s completely Big-O Open, is making inroads in dev boards, Arduino-ish things, and some light Internet of Things things. That’s great and all, but...

Followers of the Church of Elon will no doubt already be aware of SpaceX’s latest technical triumph: the test firing of the first full-scale Raptor engine. Of course, it was hardly a secret. As he often does, Elon has been...

At the dawn of every new year, many people make resolutions of some sort. Some resolve to live a less materialistic life and trim their possessions, and in our year 2019 this school of thought has been turbocharged by Marie...

It started as a joke, as sometimes these things do. [Marek Więcek] thought building a personal radiation detector would not only give him something to work on, but it would be like having a gadget out of the Fallout games. He...
