Excellent Tutorial on Building Logic IC Oscillators from Beavis Audio Research

The Beavis Audio Research Group just added a great overview for building CMOS Oscillators and LoFi Synths. Starting with your basic oscillating Hex Schmitt Trigger and finishing with a Heterodyne Peyote Space Explorer. The tutorial has clear examples with valuable pieces of information for adding LFOs, Rate LED Indicators, Line Level and Volume control as well as component values for good frequency ranges. Excellent work!

  1. Thanks for the heads up. The Beavis site started the diy effects bug/hobby for me a few years back. And this low fi synth project looks like a worthwhile “next project”.

  2. Heterodyning – is that a verb? Anyway the Beavis site is a great one, been a follower for a while.
