Thanks for the input, everyone. I suppose what I'll be trying is to go straight out of one of the 5v sources into the Arduino. Is it possible that this might not be enough power to run two servos? I'd like to avoid the use of a regulator if possible. I am also wondering about the 12v situation, and whether or not that really would burn the chip out prematurely. Reboticon, I know you said you were down to do some experimenting on an Xbox you've got lying around. Wanna see if one of the 5v sources will power an Arduino? Here's a list of power outs on the motherboard: http://img229.imageshack.us/i/4dyu9s2jv2.png/ Let me know what you think. Fennel Rye
Then I ran the 9v end to my arduino, which is currently powering a reciever board from a toy RC car usually operating at 12v.
