12v mobo
Looking for all in one mobo's that run off 12v adapters

Ok, this may seem obvious to some, but not to me. How/where would one find all-in-one motherboards that run off of a 12v adapter(or 19 as with the IO) so that no bulky ps is needed? Everytime I get a great idea about making some small computer/appliance or sticking an LCD screen and computer somewhere neat I run up with the problem of the ps and where to put it and how to power it. I've tried searching for "laptop motherboards" but cant seem to get through the list of laptop sellers and repairers(sp?). Any ideas?

Your right, very pricey. What about a supply of the boards like the one in the IO or other appliance. They seem cheap and can acomodate everything a computer needs, hdd,monitor,periphials. Theses cant be that expensive can they? The fact that they can run off of an adapter without a big power supply unit is the real attraction.

inx3us: If you don't mind pricy ($150), here is another solution.

http://www.tri-m.com/products/tri-m_engineering/v104.html

We use the high efficiency version of these at work. They work very well. They package very nicely since they can bolted directly to the PC/104 stack.

If you want cheap, keep an eye out on the surplus sites. I've found power modules from laptops fo less than $20. You may also find something like this:

http://www.mpja.com/product.asp?product=11543+PS

This particular one isn't too useful for a car since it nedds a 48v input. Every now and then a 12v input version is listed at MPJA.

Electronics run on smoke, if you let the smoke out they won't work

Check out the Easy-Now computer. I think it fills the bill nicely. If you take the guts out of the thing, you end up with a very small box, with an internal 3 1/2" hard drive, 2 IDE ports ATA66, 1 sdram slot, five USB ports, 56k modem/HPNA LAN device, 10/100 LAN port, SIS 530 chipset, sound, external 18v power supply. It'll run an AMD k62+450 at 550 or higher. You could make this thing into pratically any sort of custom-built computer. Don't know if any more are available ...I bought three for $78 each.

CKBONE, is that power supply using a std. connector like the IO uses or some sort of proprietary connector like the Netier? (the plug from the adapter into the unit) The point being I'd like to get this thing into my car.

The EasyNow does use a proprietary connector but it can be changed. The power supply is 12 volts, 5 amps.

One thing to remember, The car 12vdc line is very noisey and hostile to some electronics without some kind of quality filtering/voltage clamping.
Electric door locks and the likes generate voltage spikes when activated. That could be real hard on the Mobo,disk drive, etc.

Check http://www.dashpc.com for some good info re: car-powered computers. It's quite an elegant setup, really.

I had seen dashpc b4 and forgot all about it. That is a fine set up. I think I now realize what I'm looking for. I found a carmp3 site and the guy there had used a laptop power supply to run his mobo and HDD and stuff. They're small, take car voltage and have regulated outputs. There was even the pinouts for all the voltages. Heres a link /http://www.mattman.com/mp3/43w_dc.htm It looks like the solution for my mobile computing needs.

inx3us,

Ever get your car pc set up? Any problems with the LCD and hot weather? Especially direct sunlight?

I got one of these off EBAY... http://www.dansdata.com/bookpcblack.htm
It has tv out so I can use std auto tv's, like the ones that are coming in mini vans these days. The board is MATX form factor. The power supply is the big problem. I am firm that I want to use a DC/DC converter instead of a DC to AC converter like the "cartricity" adapter. It kinda defeats the purpose of a nice small computer and screen and then have the cheesy looking wall plug sticking into an adapter running out of the lighter. When done I want the mobo concealed, the DVD smartly stuck in somewhere and the power built in just like any other car appliance.
