There are a number of component-level voltage regulators that would do the
trick nicely, if someone in your house is handy with a soldering iron.
Beyond that there plenty of pre-packaged DC/DC voltage converters. A wire to
each side of the battery, and the other side has regulated +5vdc. "dc
voltage converter" as a google phrase reveals plenty, a search of some
surplus sites (www.alltronics.com for example) would probably yeild more.
