Anyone know where I can find a 12VDC to ATX power supply? The old MBs

are

pretty easy with only +-12VDC and +-5VDC but the ATX ones are more
complicated. And with 5 or 6 socket seven 300MHz -ish machines lying

around,

that is what I'd rather use.

Seen some plans on the web for conversions but most seemed very

non-robust.

I just had a thought, what about an old second hand notebook computer.

I

don't know what type of A/D interface you would use (pcmcia?).  Since

most of

these have a DC 12v portable power supply that would aid in

instillation.

Also the notebook could be easily removeable for ground review and

software

upgrade.  Plus, you might use it for other flight software on the ground
(logs, W/B, etc.)

Actually I have a IBM Thinkpad 365X, 100 MHz pentium, 40MB ram, 1Gig HD.
Actually my project is twofold - I need to be able to datalog serial (air
fuel ratio) in vs. sound card in (RPM) for one aspect, and play MP3s as
another :)

I just picked up an ATX motherboard with a 500MHz K6-2, with everyting
including sound, video, ethernet, USB, game port, et al built in which is
smaller than the notebook. For about $25 with shipping. So I was more
interested in the moment at using that instead of the thinkpad, which has a
bad sound card and no floppy or CD.

Nice thing about IBM thinkpads is that they will run happily off 12 - 15VDC
with no car adapter (just fab a plug adapter).
