We suppose [Dan Beaven] got up one day and said, "I'll make my own resin 3D printer, with resin management and an advanced separation mechanism!" It's a build log that shows just how possible it is ...

Wireless is easier today than ever, with many standards to choose from. But you don’t need anything elaborate if you simply want to cut the cord. A few years back, [Roman Black] experimented …

Elephants and people don't mix as well as you'd hope. Human-elephant conflict causes deaths of both pachyderms and man alike. Elephants raid crops. Elephants are killed by trains. Obviously, where e...

If you ever encounter railroad or railway enthusiasts, you may have heard the view that at some point in the past there was a golden age of rail transport that has somehow been lost. It's something t...

Your multimeter is probably your most useful instrument if you work regularly with electronics. It goes with you everywhere, and is your first port of call in most cases when you are presented with…

A toast to all the hackers out there who like to do it scrappy, who fight hard to get your products to work, who make your own tools and testing jigs and assembly lines in your basement, and who pound...

It kind of hurts watching somebody torturing a brand new Fluke multimeter with a soldering iron, even if it’s for the sake of science. In order to find out if his Fluke 12E+ multimeter, a fea…

Here's a question: when did you last listen to an AM radio station? If your answer is "recently", chances are you are in the minority.

You might ask: why should you listen to AM? And you'd have a p...

[Robert Glaser] kept all his projects, all of them, from the 1960s to now. What results is a collection so pure we feel an historian should stop by his house, if anything, to investigate the long-te...

It’s been nearly four years since we covered [Thiago]’s OpenPLC project. He never stopped working on it, and now it’s in a highly polished state. If you read our initial coverage …

It takes balls to learn how to juggle, but once you do you're quickly moving on to rings, chainsaws, and those very strange juggling clubs. For their Hackaday Prize entry, [Laurent B] and [michael.cre...

If it were sixty years ago, and you were trying to keep a secret, you'd be justifiably glad that [Ben North] hadn't traveled back in time with his Raspberry-Pi-and-FPGA code-breaking machine.
