figured id post a schematic for my psu in case anybody wanted to try to make it. not sure what the amperage output is. voltage is from 3-13 or something. i dont recall where the scribbles came from but theyre in pen so i couldnt remove them
www.stores.ebay.com/Zet-Biz prices seem pretty fair
http://sales.stonetek.org/index.htm seems to be cheaper though :\ demmit....
EDIT: Fixed link by things ;)
