Fritzing

Uses two transistors.

Using two transistors, this circuit amplifies voltage received through the male connector behind the resistor (which protects the circuit) as if it were an antenna.

SAFETY WARNING - Like when working with high amperages, be careful when working with transistors, especially transistors arranged in a Darlington pair, as it could overheat and either partially explode or catch fire, both of which happened to me when I wasn't being careful (and both of which scared me.)
