This project is a simple, variable-frequency sine wave generator built on the Arduino platform. It uses Pulse-Width Modulation (PWM) to produce a digital approximation of a sine wave, which is then ...

I am not sure why pulse generator buffers are so fascinating at the moment. It could be that the workshop’s only crystal-backed generator that can run from 0% to 100% duty cycle is still broken, or it ...

When multiple PWM converters are connected in series (or in parallel) in a power electronics circuit, it is appropriate to run all converters at the same frequency but with certain phase shift among ...

Feeling a bit left out because he didn’t have a PICAXE on hand, [Rob Miles] decided to port the Luna Mod code so that it would work on an AVR chip. He chose to build his around an ATtiny45, but also ...
