How many D cells, Larry? Adapting it is as easy as a 3-terminal
regulator IC to make the proper output voltage to match the D cells.
6 cells - 9 volts - LM7809 regulator. Too easy!.....Bolt the
regulator to a little heat sink on the battery case.

Hi Larry,

Actually, I was wrong. It uses 3 "C" cells (not "D" - I just checked),
but you're still correct - a three terminal regulator set for 4.5 volts. I
suppose I could fit a dowel assembly with contacts and bring the
connections out through something reasonably waterproof. The reg would
probably have to be outside, though, as it's likely to throw off a bit of
heat, don't you think?
