Still trying to attach a GPS for my car computer.

It has a Special function.It can display a vehicle current running details of Vehicle Engine details like ( Engine RPM,acceleration,Engine temperature,Water temperature,errors and troubles in engine,etc)

And If you are a doing Motor Sports or if you have any custom ECU in your car like GEMS,Motec,AEM,Greddy Racing ECU' can easily connect with your ECU through the USB or RS232 and can Tune your ECU as you want.Because you want anymore your LAPTOP or other PC.If can attach like this PC in your Car really can have a nice easy time. :)

    The hardest part is to install it properly hidden in your car!
    Nice instructables, I was planning on doing this soon. I was planning on using an laptop, as I had no idea there was special case/powersupply for car!

    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?

    Not Windows!! You'll crash!!!

    What you mean by this my friend?
