So I'm just now getting into building. I've circuit bent a few things, and abandoned several others along the way. I realized bending all the cheap stuff with SMDs was probably the source of my headache. So I've got a simple PT2399 on a breadboard that I'm gonna work on modding up nice & dirty, a CV amplifier that's being re-planned, and I've got the parts coming for my next project: a crash sync fuzz (a la Your & You're).
I had read up on a cool sounding mod that I'm interested in implementing, but couldn't find an exact schematic for. Basically I want to make an envelope follower/detector circuit. I've got several types of op-amps and a few other ICs either already lying around or being shipped to me, and I think that'd be the core requirement for this little circuit. The envelope follower would in turn change the frequency of the oscillator to coincide with my attacks. Does anyone have a schematic for a simple (seriously, I don't really care if it has a sensitivity adjustment or anything, though that might be cool to add) envelope follower circuit that'd be fine-tuned to passive, single-coil-level volume?
