This is Joule Thief made using a two part ferrite noise supression filter.  The Joule Thief is wound up on one half shell and a secondary coil is wound on the second.  When placed together a step up transformer is made.  I show the device powering two blinking LED and a solar waving motor.  The power source is a tiny solar panel from a solar waving toy.  The modified Joule Thief (blocking oscillator) circuit is the same as found in my 'Penny Oscillator'.
  This is where to get the ferrite core:
