Introduction: 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!

AAANNNNDDD... my battery is only at like .9 volts so it works GREAT!!!

haha thats nice, I was going to make a smaller one but I didn't have any wire >.<

lol i was using this as a nightlight and my battery picke a perfect tome to blow up all over it >_<

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.

ya its good, i like it.

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

yeah i know, I use to be a big fan of harry potter!
