Discover how to create a simple magnetic generator using everyday repurposed materials in this step-by-step guide. We use items like a Fanta cap, DC motor, old CD, magnets, syringe plunger, and a ...

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 ...

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.

A decent signal generator is handy for tuning electronic projects. [SC] sent in this AVR signal generator. The parts count is really, really low. An ATMega8 is the core, and a shift register runs the ...

This is a very simple square wave generator circuit built with IC 74LS00 that can generate square signals with frequencies between 20 Hz and 1 MHz. Its stability is good enough for most applications.
