LED Throwies

LED Throwies are small self-powered lighting devices that can be stuck to a surface to provide illumination or decoration. In the original design, each throwie is attached to a small rare-earth magnet; throwing it at a metal surface will cause it to stick. They can also be attached with adhesive tape or putty or just thrown around without any attacment mechanism.

Electrically, each throwie includes a LightEmittingDiode?, LithiumBattery?, and usually a resistor?. Bound together with a piece of tape, the entire device usually costs less than $1 if the parts are bought in quantity.
