Here is a little phototheremin I made for B. Its just a little 555 astable oscillator with a photoresistor controlling the pitch. The silver knob is for volume. It was the first thing I built from scratch (except for the box, which I got at Micheal's), so it is a bit wonky looking inside. I need to replace the AA battery pack with a 9v battey holder because the two AA batteries don't supply enough juice.
