Piggyaxe Joule Thief Kit

A kit of parts to build the ultimate 'Green' circuit that uses the cells that other people throw away.

The Joule thief is a simple circuit, but it delivers great functionality. Its name is derived from the concept that it's stealing energy (Joules) from the battery that powers it. Nothing special there, except that this circuit will work down to absolute cell exhaustion at around 0.5 volts. Hence the idea that its 'stealing' the last dregs of energy.
