PB701 Electric Intonarumori
That noise board is based on a design made by Urs Gaudenz from Schweizer Gesellschaft Für Mechatronische Kunst - thanks for that!
I added the voltage controll and some extra funcions, like the noise on/off the boost and the mute function.
The Electric Intonarumori has an audio an an control voltage input, while building the board one has to choose between bus 1 and bus 2 for the audio input and the other bus for the control input.
