Hi Dan -
If the voltage is noncritical enough to accept 5.1v instead of 4.7v, perhaps
just a resistive voltage divider would get you through the weekend, or, if
the load current varies quite a bit, a series of plane old diodes, allowing
for the difference in voltage drop between silicon and germanium, might
accomplish the task, or foot that matter, three nominal "!.5" volt batteries
would get you pretty close. It all depends on how important the contest is.

Dan,
RadShak used to sell 5v Zeners. Might check that out.
