These are my build notes for the Bong0.
Its a Eurorack module from Non-Linear Circuits
"The bong0 is a twin-T based drum module with a LED acting as a nonlinear resistor to give it some interesting characteristics.
The trigger input acts as a normal input to get your drum sound. The
input marked ‘in’ can also be used, or you can jam a CV in there, or a
gate or audio. You can just use the ‘in’ input without anything into the
Bong0 can also be used for basslines, drones and as a crude but useful
VCO. It has about 20 passive components which are 0805 smd and 1
thru-hole TL072, meaning it is a good circuit for learning to solder smd
parts and delivers way more fun than such a simple module should." (Andrew F).
