    Ok I am ready to start designing my own carpc :) Have a few Q's

    Thanks to reading many of the posts that are on the forum here I am now conviced that this is what I want to do.

    What I want to start with is the following:

    1. In dash monitor - Alreay have it
    2. Motherboard - Not sure the best way to go. I see many with the small miniITX boards so I am leaning that way since it will have the on board s-video out and audio built in. What is a cost effective miniITX or microATX board that would have built in s-video, audio, etc?

    - I do not want the system to take forever to boot up. I am not sure if windows or linux is my best option yet. I was thinking about the following IDE -> Compact Flash adaptor for the OS. The link is: If I am reading this right I could load linux and the needed programs on the CF and use the harddrive only to house mp3's, video files, etc. Will this work? Would this make the shutdown process a non-issue since there is no harddrive involved in the boot process?

    3. I would be interested in going to a touchscreen monitor when I can afford it. Does it really make that much difference or is using a remote easy enough? I really do not want this to make driving harder rather more enjoyable.

    4. What is the best way to power the above board in the vehicle? I see many homebrew supplies as well as some commercial.

    5. What is the best software from a navigation standpoint? I do not want anyone to ever have to see the windows or linux interface but rather I would like the system to boot and go directly to a very easy to see and use interface. (I am looking at Media Engine, DashPC, or Carpc software...any recommendations?)

    Sorry to have such newbie questions but I can not afford to spend, spend, spend just to find out that I need to change stuff. (Although some things will change as I gain experience I am sure)

    Thanks in advance for your assistance,

    the ide to cf adapter seems nice and it does work but from what i know they wont have that long of a life
    cf cards only have a certain tolerance for writes. after a bunch of writes to the disk it wont be usable
    having your pagefile on the cf card would kill it pretty quick id assume

    Best thing to do is treat the CF card like a CD-ROM. Make it read only so you don't kill it prematurely with a bunch of unecessary writes. Any writing should be sent to the HD.

    well the program, I just used the mediaengine. I mean it gets the job done for now, I have have the startup load up a shortcut of it..simple enough.

    you can try teh EPIA-M 10000 ? (1 gig) boards.

    Yes you need touchscreen, I couldnt imagine using a mouse or anything else while im driving. But I've noticed its just impossible to use an onscreen keyboard to type stuff in -- working on that.

    powering, I just got an opus and called it a day.
    Mine needs to be updated.

    True Touchscreen or Touchscreen overlay?

    Thanks for the replys. I have noticed that you can purchase a True Touchscreen from DS Customs for around $400 or if you have your own monitor you can purchase the overlay for much less.

    What do I need to look for in a screen so that I can see it during the day? I really would be ****ed if I spent the money on a screen, mounted it in the dash, and found out it was usless during the day.

    Is there any advantage for one over the other? Is the touchscreen overlay soft or hard? (Since if you push on most LCD screens they get distored and I am afraid that would harm the screen.

    Also what mother board would I need to run the basics such as mp3, divx, maybe streets?. (miniITX)

    Finally if using the overlay will it distor the screen? (In case I am playing a movie?

    EPIA M series is a good choice and they are cheap...
    Watch for the new Nehmia core available in a couple of day

    GAIN monitor with VGA are a good choice... (DScustom)

    TM serie (composite only) are also giving really good result for the price (digitalww)

    the overlay is a hard glass window.

    You can touch your tft with the touchscreen
    Epia M9000, lili 7" vga&touch & 2xTM-7002S compo, camera with reversed image, 2.5" 60 GB, 256Mb DDR, Opus 90W, GPS usb... AND MEDIACRUISER of course!

    earthlcds sells high bright lcds...but they are pricey.

    I have seen one in person and this one was $1000 had a mechanical brighness rheostat...half bright was good enough for inside.

    mine is a DSTN, and a bit dim...mostly due to glare, and the fact the screen is not pointed at the angle...

    I haven't tested my TFT yet.
