Build yourself a quick and cheap backup power supply for charging!

This is a quick, easy, and cheap way to get decent power for charging your R/C batteries. It's just an Xbox 360 supply with the wires gathered into +12V, GND, and jumping the sense/5V wires together (to turn on the supply). Best of all Xbox 360 (or laptop or monitor) supplies are all over the place for cheap after the main units die!
I just shot and uploaded this in one take just after hacking the wires together. In review, I notice that the PS voltage was going under 12V, from the rated 12.3V, so I wonder if that made it limit it's power output. It's still a very useful PS for this application. I plan on cleaning up the connector end to prevent shorting and such too.
