Super Power JOULE THIEF

Joule thief is a minimalist Armstrong, self-oscillating voltage booster that is small, low-cost, and easy to build, no needs many materials to make it. I made this because i need to power up something in emergency situations. It can kept in a pocket, bag, and any places. This Joule thief can powering the 12volts LED with one botton cell battery! Its amazing! You can powering up any DC device with this, like Radio, Remote control, LED, Motor, and ANYTHING!”
