Learn how to create a simple DIY electrical generator using a few easy-to-find materials. This step-by-step video guides you through making a homemade generator, including winding a copper coil, ...

While function generators or analog signal generators are ubiquitous in their utility, we haven’t seen much of logic function generators on Hack a Day. Luckily, [Dilshan] sent in a really neat ...

Many power stations show you remaining battery life on their displays, but that’s only useful once you’ve got everything plugged in.

Hydrogen! It’s a highly flammable gas that seems way too cool to be easy to come by. And yet, it’s actually trivial to make it out of water if you know how. [Maciej Nowak] has shown us how to do just ...

This two-transistor white noise generator has a surprising feature – about 30dB more noise than the more traditional designs. Q1 and Q2 can be any small-signal transistors with a beta of up to 400.

Generators can get expensive, sure, but they don't have to be: Costco carries quite a few powerful generators that are ...
