It's .... an LFO.

This one isn't quite as fancy as its voltage-controlled sibling, but it is quite versatile in its own right.

The heart of the circuit is an op-amp based oscillator which produces a boring old square wave. However, add a couple of pots and some capacitors and not only can you adjust the duty cycle of the square wave, you can also generate triangle-based waves ranging from a sawtooth, through a 'regular' triangle to a reversed sawtooth and all stages in between.

One pot controls the square wave duty cycle/triangle symmetry, whilst the other controls the LFO rate. In addition, there's a range switch that allows you to change between 'low' frequency range and 'really low frequency' range, where we're talking 'glacially slow' at the bottom end of the range.

Whilst squares and sawtooths sound a bit boring, you can make things a bit more interesting by passing the output signal(s) through filters, mixers and the like.

The module is supplied with a power cable and mounting hardware, and the panel is 4HP wide and fabricated from 1.6mm FR4 (PCB material)
