airman00, Im not initially planning on using 4.8v battery power. Im using 4.8v of wall power. Basically im looking at setting this thing up on my breadboard and programming the servos to 0 and then hacking them. After I get this plus some basic programming done to test things out, I was going to solder things up and get the 6v nimh battery as the tut suggests. But for now I was just going to get a wall-wart power supply hook it to this power regulator kit from sparkfun, and put it on my breadboard. Like I said above, Im a noob in these things, but shouldnt this give a steady 4.8v of power to both the servos and the MC since its getting a constant supply of power from the wall plug?
