Joule Thief Flashlight

Our project on utilizing a 9V battery to its fullest potential. We used 4 different setting:
First setting is a dimmer at 35% power
Second setting is a dimmer at 50% power
Third setting is at 100% power or a battery connected straight to the LEDs
Fourth setting is the joule thief that we used after the battery is "so-called" dead
This was just a simple demonstration on how a joule thief is designed to work and is simulated here.
