We have a chain of stores locally that sells loads of things, all at 1UK 
pound. Most interesting lately were some mobile telephone chargers 
intended for use in a car.They contained a complete switching regulator 
- already set to 5V and capable of delivering a few hundred milliAmps 
from anything up to about 20V in.

I just took out the small circuit board and shoved the whole thing on my 
robot. Now I dont have to be careful to avoid touching an extremely hot 
regulator and the current drawn from the battery pack is a quarter of 
the processor board current - I could hardly ask for more.
