Update: see the comments below for the answer.
You'll be twisting those knobs with stubs for fingers in no time!
"Produces random voltages by comparing the time between clicks. Initially counts three clicks, then takes the time between 1 and 3 as the overall range mapped to 5V, and click 2 as the voltage level. It then waits for the next click to replace click 3, and re-assigns the previous 2 and 3 to the new 1 and 2, if that makes sense.
The 5V is converted into a control voltage signal, with adjustable range and offset, adapted from Ken Stone's joystick schematic. Glide has also been borrowed from a CGS module. Also produces a trigger output every time the geiger counter is activated."
