So you got to recharge the external battery EXTERNALLY after power
What's wrong with that? Trickle-charge the battery and ride the

A voltage regulator, converter, and a few filters will give you a
constant supply. It will last longer, and it's a lot cheaper in
Actually, this is a project of mine that's been on the back burner for
now. I'd like to add a network interface for remote controls, some
checking, and test modes, but would have to incorporate an embedded

Being that I've never messed with such, any suggestions as far as a
processor to start with? It doesn't necessarily have to be a

I know it's not a BSD-related question, but I figured I'd ask anyway.
This is another approach that seems like it would be practical:
Use deep cycle car batteries, trickle charge with solar panels.
If a desktop computer can run on square wave generated by
dc/ac converter, use that as a power backup system, It would
have to have some kind of switching system to detect main
power drop and switch to the backup system.
Perhaps someone would be willing to, with engineering expertise
put together servers that would work on laptop batteries, like a
laptop. I do have one machine that has Yellow Dog linux (Mac
Powerbook 3400c) that runs 24/7 as my backup DNS server.
