Still can’t get your hands on a Pi Zero? We know. Why not de-solder a few headers from a Raspberry Pi 2 to fit in your next project instead? Using a pair of 2.5″ HDD enclosures, [nodene…

If there’s one thing that a lot of small microcontrollers hate (and that includes the AVR-based Arduini), it’s floating-point numbers. And if there’s another thing they hate it&#8…

Wolfram Alpha has been "helping" students get through higher math and science classes for years. It can do almost everything from solving Laplace transforms to various differential equations. It's a l...

USB cables? What a pain. You can never find the right type of connector when you need one, or you can’t figure out which way is up when you plug the cable in. These problems could be a thing of the…

Internet is taken for granted. These days you assume there is Internet and only wonder if there is free WiFi to get onto it. But in the early days, connecting to a network could be tough and this w…

Nixie clocks. Nixie power meters. Nixie thermometers, speedometers, and even Nixies for personal adornment. Is there anything that hasn't been Nixie-fied? How about a Nixie kitchen timer? Beyond the ...

Ubuntu just came out with the new long-term support version of their desktop Linux operating system. It's got a few newish features, including incorporating the "snap" package management format. One o...

[Hans Peter] had reached the moment of popping the question. Going down on one knee and proposing to his girlfriend, the full romantic works. He’s a brave man, [Hans]. For instead of heading …

You don’t need an Arduino for everything! Or do you? This is an argument that plays out here quite often. Whatever the outcome, most folks agree that once you’ve dipped your feet in the…

[MisterM] is a man after our own heart. He loves to combine the aesthetic of vintage equipment with the utility of new technologies. His latest venture is AlexaPhone, which marries the ...

As much as we like addressable LEDs for their obedience, why do we always have to control everything? At least participants of the MusicMaker Hacklab, which was part of the Artefact Festival in Februa...

It has finally arrived, today is World Create Day which is being celebrated with Hackaday Meetups in 64 cities throughout the world.

If you are at one of these meetups, share the fun and excitemen...

Sometimes there is no substitute for a real working model to tinker with when it comes to understanding how something works. Take a brushless motor for example. You may know how they work in principle...

Even the most die-hard Arduino fan boys have to admit that the Arduino development environment isn't the world's greatest text editor (they'd probably argue that its simplicity is its strength, but le...

A camera slider is an accessory that can really make a shot. But when your business is photography rather than building camera accessories, quick-and-dirty solutions often have to suffice. Thus the ge...

Every new generation of computers repeats the techniques used by the earlier generations. [Kim Salmi] created an ASCII-based quadcopter simulation game using an Arduino that displays on the Arduino…

As someone who started using computers in the last century, I find the current resurgence of pen plotters somewhat nostalgic. The difference, of course, is that this century it is easier to ma…

Electronic tweezers – the kind that can test the voltage between two contacts, the resistance of an SMD resistor, or the capacitance of a circuit – are very cool and very useful if some…

[Rjeuch] liked a wooden clock he saw on the Internet, but the gears were produced with a proprietary software tool. So he built his own version. Unlike the original, however, he chose to use a st...

[Dann Albright] writes about some small experiments he's done in home security.

He starts with the simplest. Which is to purchase an off the shelf web camera, and hook it up to software built to do...
