Phototheremin

So, I built this very simple electronic instrument sometime in the summer of 2006. Here's a quick schematic:

It's really just a 555 timer IC hooked up to a photoresistor. I threw it together inside an altoids can.

It sounded like this:

tspeek.mp3 844kb mp3

I probably still have it in a bin somewhere.
