PENNY—the low power LED oscillator

This is a device that I made to run LEDs off very low power sources. I named it “Penny” because it will operate off the “2 cent battery” that I made. The coils of wire in the device are steel twist tie wire. The circuit is a “blocking oscillator” type that uses one transistor. The main purpose for Penny is to test out my low power homemade cells.
