$20    Bi’N’Tic Filter Oscillator PCB

Based on a Jan Hall design, this board was laid out by Ken Stone.

It is the same as the CGS module, but adds

sawtooth and squarewave outputs from the VCO core.

It tracks around four octaves.

On the first version, pin 4 of the LM311 needs to be connected to -V.

Simply link to to pin 1 of the same IC.
