Avast!!!! Lighting 200 LEDs on a single AA battery using the modified Fuji Joule Thief circuit. The battery, which is old and nearly dead, will not even light 1 single led by itself. A new AA battery will not light one of these leds alone. More to come when I get the time.
More on Overunitydotcom in the Joule Thief topic.
