A couple years ago I got into making electronic conferences badges by building a device for DEFCON 25 shaped like a dragonfly. Like all badges the most important design factor was quite literally h…

Who among us doesn’t procrastinate from time to time? We can’t count the number of times that we’ve taken advantage of the Post Office staying open until midnight on April 15th. A…

One of the most practical applications for a home 3D printer is the ability to produce replacement parts; why wait a week for somebody to ship you a little plastic widget when you’ve got a ma…

The HTC Vive Tracker adds real-world objects to your virtual world. While these real-world objects in virtual environments are now mostly limited to a Nintendo Zapper for a Duck Hunt clone and a te…

On the face of it, PCB production seems to pretty much have been reduced to practice. Hobbyists have been etching their own boards forever, and the custom PCB fabrication market is rich with vendor…

We’ve written about a lot of DIY robotic arms. Some of them are high-performance, some are inexpensive, and some are just uniquely fun. This one certainly falls into the last category; whilst…

The Surface Dial is a $100+ rotary control. You can turn it, and it’ll make some basic stuff happen on your Microsoft Surface. It’s silver and sleek and elegant but fundamentally, it ju…

Racing is certainly exciting for the person rocketing around the track fast enough to get the speedometer into the triple digits, and tends to be a decent thrill for the spectators if they’ve…

What do you do when you want to add a new feature to some electronics but you can’t or don’t want to tear into the guts? You look for something external with which you can interface. We…

Regular readers may recall we recently covered a neat Arduino trick that allowed you to “blow out” an LED as if it was a candle. The idea was that the LED itself could be used as a rudi…

If you have your ear even slightly to the ground of the software community, you’ll have heard of Docker. Having recently enjoyed a tremendous rise in popularity, it continues to attract users…

If you’re going to be flying around a FPV-capable aircraft, be it a quadcopter or a fixed-wing plane, you shouldn’t be surprised if bystanders want to take a turn wearing your googles. …

When it comes to IoT and robotics, the name of the game is sensors. These aren’t just IMUs and the stuff that makes robots move — we’re talking about environmental sensors here. E…

From a cockroach filled with LEDs, to an impressively dense 576 RGB LED display, and even a hunk of carpet, our final installment of the unofficial hardware badges at DEF CON 26 are beyond impressi…

The greatest hardware competition on the planet is going on right now. The Hackaday Prize is the Oscars of Open Hardware. It’s the Nobel Prize of building a thing. It’s the Fields Medal…

In one of those weird twists of fate, there’s currently a very high chance that anyone who owns a 3D printer has made a boat with it. In fact, they’ve probably printed several of them, …

If you’re desperate for a sense of nostalgia for video games of yore but don’t want to shell out the big bucks for an NES classic, you can always grab a single arcade-style game that&#8…

If you have ever had to complete a task such as building a LEGO model over a remote connection, you will know that the challenges are like an absurd grade school group project. The person giving di…

[Christian Zietz] wanted to know more about the Atari ST. He found information online from newer Atari machines like the Falcon030 and the Jaguar, but couldn’t find much else. While looking t…
