My nephew just got a Nintendo Wii and a wireless sensor bar to go with it (longer, wider range). It eats through AA batteries pretty quickly though. Anyone know how to make dummy AA batteries connected to an AC adapter so they won't have to worry about replacing the batteries in it all the time? I've found something just like this from Sony: http://store.sony.com/webapp/wcs/sto...tNumber=ACLS5K but the "batteries" are side-by-side instead of end-to-end like they are in this wireless sensor bar. The sensor bar takes four AA batteries.
