Joule Thief - LED driver - 3 volts

 This circuit can drive 100mA or more on a LED string, in a double duty cycle, due the diodes adding the two collector signals of the vibrator. If the diodes are low voltages (schottky) , this circuit could be able to use 1,5v batteries. The led blinking won't be visible due the high frequency.
