(schematic from f0 / SGMK) (february-march 2010)
About the noise-maker: it's really fantastic, it's capable of clean tones as well as caotic noise, it screams and sputters. It has one Light Dependent Resistor inside, that changes the tone and makes it really high.
The LEDs are blinking as the pots are turning. One of the pots is decicated to Voltage Starve, and this is a real killer. Fantastic machine! Build one now!
About the LDR: it maybe wasn't to good to put this inside (but it works anyway),
it should maybe have been on the lid with some dark cloth over, or similar.
About the two line-out jacks - it gives different signal on each,kind of stereo effect..

(Above) I made another one, this time with the LDR behind the coloured plastic in the front.
