Default Article about a portable PC that runs on 12v?

I saw something in the last year or two about building a PC that runs
entirely on 12V and with low power consumption. Does anyone know
where I can find that article or website?



Oh you can roll your own quite easily. Go to http://www.mini-box.com
and put together a combination of case, system board, and power supply.
You'll need to add memory and disk to it, as well. I'm currently using
an Intel system board (D945GCLF2) which comes with a dual core Atom 330
processor soldered on. I'm running my on 110VAC but it's quite a
capable system board and I wouldn't hesitate to try to build a 12VDC
system around it.

Of course you can roll your own switchmode psu from 12 volts to whatever
votage a laptop requires. That would be easiest. I've made a couple from
a circuit in the Aussie magazine "Silicon Chip" a year or so back and
they have worked well. The output can be varied from 12 volts to about
20 volts at up to 3 amps with no problems. I used mine to run a laptop
to drive my telescope in the field from a car battery supply.
