Build a theramin from an old alarm clock

This theramin project uses readily available components and the circuit is based around only two transistors, a capacitor, and a photo-resistor. The cases were built from old alarm clocks and the photo sensor and existing snooze button are used for triggering the circuit. Check out the parts list and how-to instructions at the link below.
