The synth is based around a couple 555 timers along with a 40106 Hex Schmitt trigger and a 4040 Binary Counter. I was over a friends house recently and we were listening to some acid house music and thought it sounded a little like my other fizzle loop synths. I decided to revisit the build and add a few other controls to be able to make beats.
The new version allows touch control modulation and has a built in tone and beat generator via the 4040 and 40106 IC’s. The 555 timers create the tones and these can be controlled 3 ways, through a pot, slider and LDR.
