    Thank you dear ac1D,this is really pretty small. Computer complete enclosure size is 10"x9.5"x2.8" I have hidden this under da car passenger seat.after I have used the USB hub for use the other features.I have bought the USB PC remote controller So that's really easy to power on/off the pc.Use the Intel 1.6Ghz Atom Motheboard because its too small.

    And if you want to use your laptop in car use car power aapter for th laptop :

    I have used 12V DC ATX mini power supply,you can buy it from ebay.
    Here is the link:

    Thanks for these links...i already have a carpc that i built from scratch, i wish i woulda have use the spare laptop i have at home. I know it woulda have worked because i tested out all the software there before anything...i well, i guess for the next car.

    very cool. when i get my license something like this is going in my car :D

    thanx zack247.:) cool cool.try for this.if you want more details i can reply.

    im going to attack a general PSU and see if i can find the parts to make a 12v to ATX converter, if those -12v and -5v werent necessary i could easily do it :P

    im getting a car next year, i have already started getting the parts for this, im gonna try to fit a 15" LCD monitor into it.

    No worries you can try 15" LCD..sure it will works..But try to fix a 12Vdc to ATX converter with your project,because if you use this tiny converter the project will be a pretty and easy to use.
    If you are using 15" LCD i think you should fix a little high wattage 12v to ATX converter.
    here is the link :


    the 15" LCD can be run right off the cars 12v line, i have found the pinouts fro the main control boards power connections, al i need to do now is find some white LEDs or something to replace the backlight bulbs, the inverter never worked on the screen anyway.

    i think i might get a VGA to Composite connector for both the pc and the screen, that way i wouldnt have to route such a thick VGA cable, would that work?

    i also want to know, how many cores does your Atom have?

    What you mean by this my friend?

    I'm just kidding. I've had enough experience with Windows BSOD, though.

    well so long as you have it set up with the right amount of ram and processor power (and maybe the right wattage PSU, these are a real problem), you shouldnt run into it

    Nicely executed project. This is why I love this site.

    Nice work.

    To add gps, use a usb bluetooth dongle.
    I picked one up locale for $5, but they are all over the web

    Then use a bluetooth gps. I have one of these.

    I paid about $35. Charges from car.

    Cool idea.but what is the software for this interface? can track with this interface?

    Back when I used my laptop for nav I had Microsoft streets and trips. I also tried delorme, but it didn't use moving maps at that time. Moving maps are essential for nav in my opinion.

    There are many free options but they generally require you to make your own maps.

    Agree with you we I have to make a GPS map as i wish.But the thing is i also tried Microsoft streets and trips.but there was no Sri Lanka GPS map in this first I have to find the Sri Lanka GPS map.:/

    This might help.

    Thank a lot for your reply.But I looked for that.there is no map for srilanka roads,and no tracking map.I have to find the map from here local shop.But think they won't sell those map without the GPS unit.Because they selling the GPS unit+GPS map.

    Do you know any way to download the GPS map file from car Navigation GPS unit?

    I think these guys can help you better than me.

    So far I haven't found a free alternative to using google maps or a program to download them for you.

    It would be a long process to manually save a large enough area of google maps to be usefull.
