Introduction: Mini 'Joule Thief'

About: “Let the future tell the truth, and evaluate each one according to his work and accomplishments. The present is theirs; the future, for which I have really worked, is mine.” Nikola Tesla

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!

    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.
