I'd still put a hash choke between the
VBatt and the junction of the two diodes.

I thought you liked hash...

I have a device that says it runs on 6-12 volts dc. I'd like to hook it up
to a car battery, but the alternators on such things exceed 12 volts (and
the battery at its 13.8).

So I should be able to hook a LM7812 and be good to go, right? or would
the 13.8 be too low for regulation. also these devices are going to be run
along some long lengths of wire, so I'll probably stick the regulator next
to the device, rather than near the battery. maybe stick to the lm7809
instead?
