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, ...

White noise generators commonly are used for testing purposes such as setting the noise level in bit error rate (BER) measurements, providing broadband signals for ...

[Debraj] needed a simple signal generator for a project he was working on, but didn’t have one handy. He found that the easiest and cheapest way to get clean, reliable signaling was by using something ...

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 ...

If you can turn a wrench and operate an electric drill, you can build this simple generator in two days. Turn a car alternator into a homemade wind turbine by building this cheap and easy DIY wind ...

Stepper motors are synchronous motors that step at the pulse rate of the driving signal. For the motor to move quickly, the stepping rate must be fast. However, because of motor and load inertia, the ...

When building push-pull switching power converters or motor controllers, you often need alternating pulses with a small amount of dead time between them to minimize simultaneous conduction in ...
