OK, I've been looking through the forums for a few hours now and haven't found a direct answer to my situation, so I'm just asking it....
My setup is going to be small form atx mobo w/ celeron 800 (onboard vga, sound, etc) with 1 HDD, 1 DVD-rom, and a 15" touchpanel LCD (overkill? I know. :) ). Correct me if I'm wrong, but i'm looking at drawing about 120-130W max power w/ LCD. The problem is my intensions of this setup. I want it to design it to that I can easily take the entired setup (which will be in one box. think laptop, only cheaper & with touchscreen) out of my car and put it in a friend's or gf's car for roadtrips and such. So that leaves out the option for pulling power straight from the battery and *hopefully* those big@$$ 300w inverters. My concern is the stability of the cigarette lighter connection since we're talking about using multiple cars for power. I don't want to hop in my friends car and have the fuses blow. That's happened before and he's wasn't happy.
If you are trying to go on the cheap, with the functionality of a laptop, features of a laptop, with power consumtion like a laptop; then you best bet is going to be..... A laptop.
$200 for an ITX mobo,
$100 for power solution
$200 for drives(dvd+HD)
$400 for a LCD
$150 in assorted crap that your going to need (adapters etc)
So far we are sitting at over a grand, and for that price you can get a laptop.
Get the amount of cash to spend on the project, and then plan from there.
If you like me and are using equiptment lying around then i recommend a ATX dc-dc(opus or similar) power supply as a worthwile investment (if you don't blow it up). If your a bit of a DIY dude then I should point out the flyback modification to a conventional ATX power supply. Do a search for flyback and you'll find a bit of info.
hope this helps some
if you use the inverter you'll need to connect it to the battery directly, thats the problem I ran into so beware
you can get inverters that connect through the cigarette lighter.. my current configuration is just that. I have a 300W power inverter hardwired into the cigarette lighter.... works fine... I haven't blown any fuses at all... but I agree w/ SOBIL, if your going to build a carpc then build a carpc, if you want something portable that won't blow fuses get a laptop.
My config is setup to be mobile, sort of, I can get my system in and out of my car easily, but I can't mount it into just anybodies car due to limitations around power and the way I mount my system.
Get a laptop for portability, build a car pc if its just your car... another suggestion... take your car on road trips!!
I found this website while searching the forum. Car computer complete setup with screen for under $600.00. You should get a datalux touchscreen off ebay for about $175.00. I also seen you can get most of this stuff from ebay but I like the convenience of being able to order everything from one place. I bought an fm modulator from this guy and it came pretty quick and I am satisfied. I am going after the this computer next. I want to upgrade my system. Anyway here is the link. Web LinkI just thought I would share this find. I have seen in posted other places in the forum but no one seemed to no how the service was so I gave it a shot and it was pretty good. :D
Do a search for Espresso and Cuppuchino PCs. You will be pleased.
Thanks for the input. I like nighthunter's link. But unfortunately the listed specs are the items that I have in my possession. And I've only spent around US $250 max (including monitor)! So I'm pretty proud of that. You're right, if i can't do it, i'll just run it to the battery, but i know most ppl don't like taking my car on road trips (i'll post pics when i install over xmas vacation. you'll see why :) ). hmmm....decisions, decisions, decisions. Again, thanks for the feedback.
isn't this a tablet pc basically?
