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.

This episode begins a DIY hydrogen generator build by concentrating on the electrolyzer and its place in the overall system.

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 ...

Simple triangle-wave generators have a weakness in that the waveform of their output signal normally cannot be modified. The circuit presented here makes it possible to smoothly alter the waveform of ...
