There are many different articles and videos to be found online that will teach you how to build a Joule Thief circuit and power LEDs off of dead batteries.

A joule thief is incredibly useful for squeezing the last bits of energy from supposedly dead batteries.

Today I am showing you how to make a very simple joule thief. A joule thief has many applications, the best gadget that I made with was a "Water Powered.

Step-by-step run through of how a Joule Thief circuit works. Includes how all the parts, the 1.5 volt AA battery, the resistor, the transistor and the ferrite core with its two coils of wire work together to build up energy in a magnetic field which then collapses to produce enough voltage and current to light an LED (Light Emitting Diode.) This...
