Before the AdLib sound card, sound on PCs was in a terrible shape. Since the dawn of IBM, all PCs included a speaker, but this PC speaker was only capable of sounding one note at a time. Chords on …

Visually impaired people know something the rest of us often overlooks: we actually don’t see with our eyes, but with our brains. For his Hackaday Prize entry, [Ray Lynch] is building a tongu…

One of the worst things about your average modern keyboards is that they have a tendency to slide around on the desk. And why wouldn’t they? They’re just membrane keyboards encased in c…

When we write about the 8-bit era of home computers there is a list of manufacturers whose names are frequently mentioned. Apple, Commodore, Texas Instruments, maybe Acorn and Sinclair if you are Brit...

ESP32 is the hottest new wireless chip out there, offering both WiFi and Bluetooth Low Energy radios rolled up with a dual-core 32-bit processor and packed with peripherals of every kind. We got so…

We've been trying fit in a tour of the Pacific Northwest for a couple of years now. This week is a perfect excuse. Hackaday is proud to sponsor the Open Hardware Summit which will be held in Portland ...

Flying ready-made quadcopters is fun. Eventually, though, most hackers get the urge to build their own. One of the most challenging parts is building a robust airframe. [Thomas Jarrett] has an inte…

The abundance of small networked boards running Linux — like the Raspberry Pi — is a boon for developers. It is easy enough to put a small cheap computer on the network. The fact that L…

[Micah Elizabeth Scott], aka [scanlime], has been playing around with USB drawing tablets, and got to the point that she wanted with the firmware — to reverse engineer, see what’s going…

There are times when you make the effort to do a superlative job in the construction of an electronic project. You select the components carefully, design the perfect printed circuit board, and wait f...

Three years ago we covered [Dalibor Farnby]’s adventures in making his own Nixie tubes. Back then it was just a hobby, a kind of exploration into the past. He didn’t stop, and it soon b…

[Ivan] likes to take time lapse videos. Using his 3D printer and a stepper motor he fashioned a rig that allows him to control the camera moving any direction on a smooth floor. The dolly has a tri…

[atomicthomas] is a dedicated teacher. One only has to look at the work he's been putting into book readers for for the past sixteen years. With hardware like the Pi Zero threatening cheap computers j...

If you want to really understand a technology, and if you're like us, you'll need to re-build it yourself. It's one thing to say that you understand (analog) broadcast TV by reading up on Wikipedia, o...

What's the best way to quickly move books from a vast underground archive to the library patrons who want to read them? For the New York Public Library (NYPL), it used to be an elaborate conveyor be...

A few weeks ago I asked the Hackaday community for some help and advice in buying a new budget oscilloscope. Thank you very much to those of you who responded both here online and in person among m…

[Robson Couto] never actually owned a PlayStation in his youth, but that doesn’t mean he can’t have a later in life renaissance. In particular a Japan-only accessory called the PocketSt…

A few weeks back, we got a taste for two-stage tentacle mechanisms. It’s a look at how to make a seemily complicated mechanism a lot less mysterious. This week, we’ll take a close look …

[Tony Stark Elon Musk] envisions us sending one million people to Mars in your lifetime. Put aside the huge number or challenges in that goal -- we're going to need a lot of places to live. That's a ...

For almost the last decade, desktop 3D printing has, at its heart, been centered around 8-bit microcontrollers. The ATmegas and other Atmel chips are good enough to move a few steppers and squirt some...
