https://www.patreon.com/ObserverB DIY Synth for beginners. I'll show you the basics of breadboarding and how to go from a schematic to a breadboard with a simple example for a light bulb circuit included. The synth is based on a 40106 Hex Schmitt Trigger IC. It has a sync function whose rate is indicated by a flashing LED.
