Picture of Mini 'Joule Thief'

Well, it isn't really 'mini' because the small toroids I wound didn't work :/ I used a 2n3904 Transistor since that was all I had.
I included a Lego guy comparison to size. Hope you like it! <-- More info on the coil for making a joule thief

i made an itty bitty one :D its really cool, i fit the transistor and stuff IN the torriod, and for anyone who cares, and owns a 3ds, these pictures will show up in 3D on a 3ds's browser!!!!! i just made it, and with not very many windings. AAANNNNDDD... my battery is only at like .9 volts so it works GREAT!!!

I found it in my supply of random junk, but you can make your own with a toroid and wrap it with wire. You can get toroids pretty much anywhere online or from power supplies etc.

It's so cool. The red point on the LEGO minifig hed is the Harry Potter's ray.
