The circuit is really simple and I thought that for once I would be able to make a module that works the first time. It was wrong:( When I plugged it in to test it, it made some sound but something that didn’t really look like what you can hear in the @Doolang video ! The sound is like when you don’t hear any radio…like a noise. The good thing is that it does trigger something and the length of the delay does change when I change the value of the potentiometer.
In fact I had a problem and maybe that’s where I made my mistake:
In the shema it says that if you want a HiHat or Snare it’s not the same value for capacitors.
-For a HiHat it is one of 0.68nF and one of 1nF.
-For a Snare it is one of 5nf and one of 100nF.
As I didn’t have a 0.68nF capacitor I built the Snare’s but as I didn’t have a 5nF capacitor either so I put two 2.2nF capacitors in series telling me I would get about 5nF (I found this after a very short search: ). I test with my multimeter: not all 5nF
Anyway I tested the circuit with several different capacities but I always get the same thing so if someone has already done it and could help me I don’t say no!!!
Thanks for your help!

This module seems to work, its aim is to produce a white noise like the noise between radio stations (as you say), and then it is triggered very briefly to obtain the sound of Hit or snare
so with a trigger signal
With what do you trigger it ?
oh sorry I’m an idiot I didn’t pay attention and I put the wrong image on it
I put two 2.2nF capacitors in parallel and not in series
it corresponds to this one:
Just a little thing to know, the Decay increase and decrease also a little the Tune. It’s not me because it make the same thing in this vid
but I find that it is a good simple and effective module.
coupled with my Bass Drum ++, like it !
I built this for my workbench, hence the pin sockets for power and outputs, but it could be adapted for synth use. Circuit is the variable waveshape LFO by Kassutronics. I left out the sine shaper for simplicity and I socketed the integrator cap (C5) so I can switch frequency ranges easily — right now it’s 2.2 nF for audio frequency. “Shape” pot varies the width of the pulse output and varies the TRI/RAMP output from sawtooth to triangle to ramp.
