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 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.

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.
