wire red and black up to a 12volt wall wart power supply.
you can use less than 12volt wall wart, but you will have a lower speed

The wall wart is the adapter pack that most electronics have.They have a great switchable one
at Radio Shack for cheap.

Yah, sure you can use a 12v battery. Look in your junk electronics stuff for this. look on the power supply for 12v or close to under that. Nothing over 12v.
