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!

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.
