Do you have a Radio Shack store in your area?
you will need:
1 ea 7806 voltage regulator (part# 1392008)
2 ea 1uF tantalum capacitor (# 272-1434 )
1 ea heatsink grease ( # 276-1372 )
1 ea heatsink ( # 176-1368 )
once you get those parts I will explain how to hook everything up
note: I am an electrical genius, i can do it, and it will take me a lot of time explaining it to you in words, the easy way is to draw you an electrical schematic, but I can't do that on here, and I'm not going to go to all the trouble explaining it when your too cheap or lazy to visit a Radio Shack and not buy the parts that's needed, the parts are cheap, costing less than $10 to $15
