Hey folks,
I've been working on a simple Tremolo pedal using a Hex Schmitt Trigger (4584) to switch an LED facing a LDR (in heat shrink).
I got off to a great start and it seemed to work better than expected, but then I noticed if I used it for more than 5 - 10 minutes the frequency would go very high and the usable range would be almost impossible to dial in. I've included a schematic and vero layout. Any thoughts?
