I made two sound boxes in short time:

(october to dec 2010) The Cracklebox (Kraakdoos) and Heterodyne Space Explorer



Cracklebox with voltage starve-pot, speaker and lineout.
Box made from an old butter box.


heterodyne space explorer

Heterodyne Space Explorer, four simple squarewaves from one IC 40106.
It also got voltage starve-pot and mixer. The switches changes between resistor and diode.
