Electronic drums are pricey, but the drums themselves are actually very easy to make. By simply putting a few piezos on some rubber mats, you can make a set of electronic drums. The real trick, and th...

If you've ever corrupted a flash memory on a power failure, you'll be glad to hear that the ESP8266 SDK implements a very secure and almost infallible read/write management for its flash memory. The ...

We all use 74 logic in our projects as general purpose logic interfacing glue. These chips have become as ubiquitous as a general-purpose op-amp, or even as passive components. In most cases we&#82…

This book is scary, and honestly I can’t decide if I should recommend it or not. It’s not a guide, it doesn’t offer solutions, and it’s full of so many cautionary tales and …

[James Liang], an engineer at Volkswagen for 33 years, plead guilty today to conspiracy. He was an engineer involved in delivering Diesel vehicles to market which could detect an emissions test scena...

Your local hardware store or garden supply center probably has everything you need to install landscape lighting all around your property. What’s a little less likely is coming out of that si…

Needless to say, we're fascinated by LEDs, laser diodes, and other blinkies. Although we can get just about any light emitting thing, the data sheets aren't always accurate or available. For his Hacka...

Can you make a spectrometer for your home lab all from materials you have sitting around? We might not believe it from a less credible source, but this MIT course does indeed build a spectrometer from...

At first, we thought we were having deja vu, but then we saw this video embedded below. [Thijs Eerens] is a creative technologist (dare we say, a “hacker”?) who builds giant-scale games…

[MattB] decided to go the DIY route for some 7 segment displays that were several inches tall, but he had some particular requirements. He wanted precisely shaped elements that were as cleanly and …

You never know what you'll find when you open the projects feed on Hackaday.io. Most weeks, The Hacklet follows a theme of some sort. Sometimes I find projects that just look so cool that I have to ge...

[James Bellafaire] wanted a good looking old radio with a modern sound. Granted, you could hollow the case out and replace it with an iPod. Or you could convert the thing to an Internet radio. But whe...

Unless you are under age 20, there are probably things you know now that you wish you knew growing up. Even on hacker projects, it isn't unusual to do better on your second whatchamacallit than on yo...

[Barry] has an expedition planned. He's going to be exploring coastlines, inlets, and other shallow waters where even small ROVs are too big. [Barry] wants an autonomous vehicle on this expedition, th...

Clay is a shapeless raw material that's waiting to be turned into awesomeness by your creativity. So is the Raspberry Pi. [Dorison Hugo] brought the two together in his artfully crafted SNES micro - a...

If you have ever worked on a motorcycle on a regular basis with a limited workshop, you'll know the challenge of taking off one or other of the wheels. You'll probably have plenty of tales of bikes ba...

If you haven’t jumped on the ESP8266 bandwagon yet, it might be a good time to get started. If you can program an Arduino you have pretty much all of the skills you’ll need to get an ES…

Step one to most electric longboard builds is typically the acquisition of a foot operated longboard, with step two being the purchase of a ready-made motor bracket to electro-convert the strenuous…

You know about the Hackaday Superconference, right? It's the greatest hardware con ever, and it's happening on November 5+6. Details incoming shortly.

The Hackaday Retro Edition exists. It's the H...

A tube is a tube is a tube. If one side emits electrons, another collects them, and a further terminal can block them, you just know that someone's going to use it as an amplifier. And so when [Asa] h...
