Three cascaded gated oscillators from NAND Gate Schmitt Trigger chip CD4093 from example in Nicolas Collins' book "Handmade Electronic Music - the art of hardware hacking". The variable resistors are one pot and one LDR and one digital potentiometer (DS1804) driven up and down with Basic Stamp. I experimented with different size caps here, from 0.01 to 1uF.

A couple of photos taken at the excellent demonstration by the Association of experimental electronics at Pixelache on Saturday. There are lots more photos of the weird and wonderful things they make on their website.
P.S. Special thanks to Olegtron for the trip to the Kirppis in Turku.
