A while back this list discussed a benchtop
multiple voltage supply.? I am a
farm kid who likes gadgets and am frustrated by all the individual voltage
adapters I need to plug into the cig lighter, so I am looking for something to
probably hardwire into a rig that will supply these various voltages.
?
Right now I use PDA (5v 2A), Panasonic Laptop CF27 (10.8 V
at 1? Amp) and GPS 12 v at an Amp.? I would also like to have a small diode
protected backup battery, so that when I start the engine the GPS won¡¯t
drop out.? Both the laptop and PDA
have bats in them, so I¡¯m not too worried about them.? I¡¯ve used several separate devices,
but none is very satisfactory, and the 5V deal is now supplied by 12v to 110v
inverter, then through a wall wart back down to 5V ¨C well, it works and
better than the variable voltage converters that I¡¯ve let the smoke out
of for one reason or another.?
?
I see several voltage converters, but nothing that fits the
whole bill, by itself.
?
Anyway, I guess I could build something, but I¡¯m
really a mechanical guy not an electronics guy ¨C but am kinda an electronics wannabe.? Any suggestions ¨C volunteers?
