Ok, so I can use a 9v battery then, right?
Yes... kind of.

The little PP3 9V batteries don't last long though, as they have very little capacity, and with a linear regulator they last even less time.

If you want it to last a while you should be looking into other power sources, like Lithium Ion / Lithium Polymer, and switching (buck / boost) regulators.

A typical PP3 has only 565 mAh, whereas your normal AA battery has 1800-2600 mAh.

the receiver work  
4 AAA one diode makes 5.3 volts and will keep you from hooking the battery's wrong  smiley-lol
