What a joule thief is and how to make a joule thief to run an LED off of a dead battery, or a zombie battery. The zombies in this video will sound strangely familiar to anyone familiar with Minecraft. This uses a NTE123AP transistor, a 820 ohm resistor, an LED, a toroid ferrite core wrapped with 30 gauge and 26 gauge wire coils, and a breadboard.\r \r See also my How a Joule Thief Works video here:\r \r \r For how to make a joule thief power a comp fluorescent light (CFL) watch How to Make Joule Thief Light a CFL - Jeannas Light:\r \r \r For all sorts of measurements and demonstrations of my joule thief powering a CFL watch Fun with Joule Thief Powering a CFL:\r \r \r Zombie battery animations done using Blender 2.63.\r \r Follow me on Twitter:\r \r \r
