Hammers! They’re good for knocking in nails, breaking things apart, and generally smashing up the joint, if you’re in such a mood. Typically, they’re made of iron or steel and com…

Infra-red remote control is something of a Done Deal when it comes to hardware hacking, it has been comprehensively reverse engineered, and there exist libraries and software packages to seamlessly…

It seems kind of obvious when you think about it: why not just stick a solar panel on a quadcopter so it can fly on solar power? Unfortunately, physics is a cruel mistress, and it gets a bit more c…

Arduino now has an officially supported command-line interface. The project, called arduino-cli, is the first time that the official toolchain has departed from the Java-based editor known as the A…

We could watch cellphone teardown videos all day long. There’s something pleasing about seeing how everything is packed into such a small enclosure. From the connectors, to that insidious glu…

You may have asked yourself at one time or another, “Self, what happens when you pass 100 thousand volts through a printed circuit board?” It’s a good question, and [styropyro] pu…

If your interest has been piqued by the inexpensive wireless-enabled goodness of the ESP8266 microcontroller, but you have been intimidated by the slightly Wild-West nature of the ecosystem that su…

Working with hydraulics usually means having a fluid tank and valves. [consciousflesh] does away with both those for his DIY hydraulic artificial muscles. Instead, he uses a pair of muscles, both p…

It was announced at the beginning of March, but now the Raspberry Pi Power over Ethernet (PoE) hat is out. Thanks to the addition of a new 4-pin header on the Raspberry Pi 3 Model B+, the Pis can g…

If you move among artists, you may have encountered a few printmakers. They create a drawing by cutting through a wax layer that has been deposited on a sheet of copper, then etching the plate and …

As is always the case with a significant hacker camp, we’ve been awaiting the official badge announcement for the upcoming Electromagnetic Field 2018 hacker camp with huge interest. These bad…

RCExplorer, or [David], or just ‘The Swede’, has come up with a bicopter kit. Yes, there are a lot of people making frames and kits for quadcopter, multicopters, drones, and so forth, b…

3D printers have long since made it easy for anyone to make 3-dimensional zoetropes but did you know you can take advantage of a 4th dimension by stretching time? Previously the duration of a zoetr…

Today I don’t have a hack for you. I have a story, one that I hope will prove useful to a few of you who are considering a move to Asia to chase opportunities here. Seven years ago, I was a pretty …

If you’ve done much 3D printing, you probably curse how plastic warps as it cools down and heats. There’s nothing more upsetting than watching a six hour print start curling off the bed…

It’s often said that necessity of the mother of invention, but as a large portion of the projects we cover here at Hackaday can attest, curiosity has to at least be its step-mother. Not every…

Today is the start of the Musical Instrument Challenge. This newest part of the 2018 Hackaday Prize asks you to go far beyond what we’re used to seeing from modern musical instrumentation. Tw…

One of the core tenets of free and open source software licenses is that you’re being provided source code for a project with the hope that you’ll “pay it forward” if and wh…

Sometimes a mix of old and new is better than either the old or new alone. That’s what [Brad Carter] learned when he was given an old 1990s sound board with a noisy SCSI drive in it. In case …

Oh, there was a time when you could prototype just about everything on a breadboard. The CPU in your computer came in a DIP package, and there were no BGA packages. to be found anywhere. In the for…
