"An ambient light source and square-wave nosie maker.
The synth is based around a 4093 quad nand gate CMOS chip.
Capable of hideously beautiful beepy noise.
The 4 cascaded oscillators interact with each other to create a relentless range of synth tones.
The power starve dial adds further modulation and manipulation of the oscillations.
The noise-making circuit is built into a Mood Cube I got from RED5.
The Mood Cube lights up using 3 LEDs. I hacked the circuit to affect the rate of the light cycle.
I also added a voltage starve for this circuit too. The reason being this; when the LEDs are on full power,
they drain power from the 4093. This in turn adds further lovely modulation to the tones.
The controls are as follows:
4 dials on top to control the rate and tone of the oscillations.
1 dial on the left side for the 4093 power starve.
2 dials on the right side. 1 for LED rate and 1 for LED intensity.
2 switches on the front. 1 momentary push button and 1 toggle switch.
1 output jack located on the back side.
1 on/off switch and 9v battery holder on the underside of the cube.
The cube fits well into the palm and can be enjoyed by anyone with a passion for harsh, grinding noise terrorism and pretty colours.
It's powered by a single 9v battery which is housed in the bottom of the cube.
There's a 6.35mm jack socket for hooking up to your amp/mixer/effects.
There's no internal speaker!"
