World War II can be thought of as the first electronic war. Radio technology was firmly established commercially by the late 1930s and poised to make huge contributions to the prosecution of the wa…

[TJ Hunter] wanted to find some of the rarer Pokémon without draining his smartphone battery while staring on a screen. The handy ø 25 cm Pokéball he built to make the endless marches more tolera...

Building your own smartwatch is a fun challenge for the DIY hobbyist. You need to downsize your electronics, work with SMD components, etch your own PCBs and eventually squeeze it all into a cool e…

Sometimes the best way to learn is from the success of others. Sometimes failure is the best teacher. In this case we are learning from [Tim Trzepacz]'s successive failures in his attempt to solder on...

The Maker movement is a wildly popular thing, even if we can't define what it is. The push towards STEM education is absolutely, without a doubt, completely unlike a generation of brogrammers getting ...

If you were to ask someone who works with RF a lot and isn’t lucky enough to do it for a commercial entity with deep pockets what their test instrument of desire would be, the chances are the…

[Ncrmnt] had a busted tablet PC with an Allwinner A23 SoC inside. He combined two of our favorite past-times, Linux hacking and 3D printing, to make a rather sweet little single-board-computer out of ...

Hackaday.io contributor extraordinaire [davedarko] gets hot in the summer. We all do. But what separates him from the casual hacker is that he beat the heat by ordering four 120 mm case fans. He then...

The folks at Swindon Makerspace took possession of a new space a few months ago after a long time in temporary accommodation. They've made impressive progress making it their own, and are the envy of ...

Hackers need fuel to hack. In general that fuel comes in the form of food, water, and caffeine. Not necessarily in that order. While soda or energy drinks will do in a pinch, the best hackers know …

We're not sure what a typical weekend at [Walter]'s house is like, but we can probably safely assume that any activity taking place is at minimum accompanied by the hum of a 3D printer somewhere in...

In a world full of products that are only used for a brief time and then discarded, it gives a lot of us solace to know that there was a time when furniture was made out of solid wood and not parti…

When the Raspberry Pi was introduced, the world was given a very cheap, usable Linux computer. Cheap is good, and it enables one kind of project that was previously fairly expensive. This, of course, ...

A Raspberry Pi Zero is down to a price and size where it's just begging to be integrated into your projects. Unless, that is, if your project involves a lot of 5 V equipment. Then it's just begging to...

It always seems odd to us that magnetic levitation seems to only find use in big projects (like trains) and in toys. Surely there’s a practical application that fits on our desktop. This isn&…

Growing up in the 70s and 80s, a go-kart was a quick ticket to coolness, second maybe to a mini-bike. In both cases, a welded steel tube frame and a cast-off lawnmower engine were all that stood be…

The Joint Quantum Institute published a recent paper detailing a quantum computer constructed with five qubits formed from trapped ions. The novel architecture allows the computer to accept programs f...

As the many many warnings at the base of the Open Surgery website clearly state, doing your own surgery is a very bad idea. However, trying to build a surgery robot like Da Vinci to see if it can b…
