In part one, I compared the different Analog to Digital Converters (ADC) and the roles and properties of Delta Sigma ADC’s. I covered a lot of the theory behind these devices, so in this inst…

The once successful Kickstarter and National Science Foundation (NSF) research grant winner Electroloom is saying "Thanks and Farewell" to its backers, supporters, and sponsors. The startup ran out of...

If I can offer one piece of advice to the Hackaday readership, it is this: Never, ever, be the sole member of your hackerspace’s board that owns a large station wagon, unless you relish the t…

One of the big stories of last year was the fracture of the official Arduino supply into two competing organisations at daggers drawn, each headed by a different faction with its origins in the team t...

The inverted pendulum is a pretty classic dynamics problem and reaction wheels are cool. That’s why we like [Mike Rouleau]’s self-balancing stick. The video, viewable after the break, w…

Like many of us, [Lee] wakes up every morning grumpy and tired. Once he decided to try to do something about it, he settled on making a sunrise alarm clock using NeoPixels. Over the course of thirty m...

[Yann]'s DYPLED entry into this year's Hackaday Prize isn't very useful to most people. It's a tiny module that connects to a 16-bit parallel bus, and displays a hexadecimal number on a few LEDs. It'...

We thought we were going to read an article about, perhaps, a quadcopter that could fetch beer, or donuts. What we got was more along the lines of a donut dragging itself across the floor, rendering i...

Tattoos are an ancient art, and as with most art, is usually the domain of human expertise. The delicate touch required takes years to master, but with the capacity for perfect accuracy and precisi…

We’ve had two previous articles in this series on turning a personal electronic project into a saleable kit, in which we’ve examined the kit market in a broader context for a new entran…

Developing into a modern hacker and tinkerer requires a lot of things: electronics study, programming knowledge, and patience (among many other things). But, the most important quality a hacker can ha...

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 ...
