"SWC Spaceyards' 4th DIY 'synth' creation (enclosure still under construction). This is a 40106 IC based project, with a 741 based resonant LPF circuit. Control details: LFO knob X 1, Voltage Sag knob X 1, Panic Button X 1, OSC pitch knob X 5, OSC hi/lo capacitor switch X 5 (osc range), OSC PWM knob X 5, OSC 1n914 diode/33k resistor mix out switch X 5, Filter Cutoff Coarse knob X 1, Filter Cutoff Fine knob X 1, Filter Resonance knob X 1, Master Volume knob X 1. Additional Tomfoolery: LED chaser circuit controlled by LFO pot.

The circuit is self-designed, with extensive reference/modification to circuits found on the Beavis Audio Research homepage, and the Cacophonator and the Weird Sound Generator projects."

"The Greenotronic Cacophonetic Heterodyne Space Explorer... This is my 3rd DIY 'synth-a-like' after 2 Atari Punks... I based this unit on a combination of schematics I found online, with the basic idea coming from Beavis Audio Research's Heterodyne Space Explorer. I added a dual LFO inspired by the Cacophonator, and a resonant filter as found on the Weird Sound Generator. I also added an extra set of SPDT switches (white capped deals near the top of the faceplate) which alter the octave of the oscillators (capacitor choice really). Not so visible are LEDs I wired inline with the outputs of each oscillator. The second generation of this beast is already under construction... mwuhahahahaaaaa"
