This is a small little kit that allows you to assemble your very own Joule Thief! What is a Joule Thief? It is a small circuit that uses dead 1.5v batteries to power a 5mm LED. (A Joule is a unit of energy.)

Works with AA, AAA, C, and D cells.

It takes very little time to assemble, but yields a very neat device! Great for learning about electronics.
