Newbie with slight problems getting started...

**Shamingo** · 02-10-2006, 09:25 AM

So I am very new to this forum, and to the actual construction of a CarPC system, yet I have been reading up on these since I saw Dashwerks' Dash PC over 4 years ago. I own a 2003 Mazda 6s. I just ordered the following items:
Vehicle Point of Load DC-DC Converter 15 Watt (For the screen I thought)
Extra Monitor Power Cable
Lilliput 7" VGA Touchscreen 619GL
512MB of Kingston Hyper-X DDR 400 Memory
Seagate 250gb sata hd
A prebuilt carpc from Caseoutlet.com consisting of this:
Travla C158A-M1DC (It said it could wire directly into my car)
VIA EPIA SP13000
Compact Flash Drive (I wanted to boot off a CF card)

I know how I am going to run everything and how it will be setup within the car, I know what OS I am going to use and what frontend. I don't have any clue how to power it all though. I would imagine that the built in powersuppy in the carpc I bought is a M1, I have heard this is a good supply. Was I wrong in buying the P.O.L. converter for my LCD? Please help me configure the power of this pc properly, I'm desperate.

Thank you for your help in advance

Dargue, be nice man!
I can answer this for you Sir, don't mind Darque:
Here ya go:
You have a couple options for your Lilliput. It should come with a cigarette lighter with the infamous egg-shaped voltage regulator. These are known to flake out, however. Some people have been using their 'egg' for a long time with no problems.
That POL PSU isn't a converter of any sort. It merely provides clean, consistent power. You don't have to convert DC to DC.
If you purchased the Opus POL unit, then it can be set to provide 12v for your screen, so long as it uses less than 1.25amps, as that's all the 12v power it can provide. Check the specificiations of your Lilliput.
The Carnetix POL unit only provides 5v output, so if this is the unit you have, you're SOL for powering your screen with it.

Have you read the FAQ on power supplies? If so, okay. If not, go to the FAQ Emporium and check out the FAQ on power supplies. Actually, click on the link in my signature to go to a FAQ to the FAQ's with several links explaining power supplies.

What you need to do is calculate how much power your setup will consume. Again, there is a FAQ in there that discusses this.

Once you know how much power you need, take a look at the Opus power supplies. You probably need one of those, you just need to know how big of one to get.
