--I power my laptop from a 12v to 117ac converter, using the laptops
home power supply. Rat Shack has them for 29 bucks. Simple and you can
keep the battery charged as well!

** Please do NOT cross-post messages to multiple mailing lists on the

What you need is a DC-to-DC converter. You can sometimes find one that
will suit your needs or build your own, using a filament transformer. It
is a low frequency oscillator stepped up to whatever voltage you need,
then rectified and filtered. Good luck.
