    Post Newbie with a starting project

    Hellow.
    I want to share with you guy an idea for bulding a pc car with the parts that I want, the pc is going to be based on linux probebly moblin, didnt test it yet.
    The motherboard isn't the main thing here, all the connection is my start point and I have to understand how to connect so her the part I ask you, please, help me.

    Power to the computer:
    An DC-to-DC: http://www.mini-box.com/M4-ATX

    Screen:
    http://www.cartft.com/catalog/il/894 (or someyhing else better that you suggest)

    that the main parts.
    with other little things for make it more nice.


    the first question for this thread is how I get power to the LCD.
    so I was searching and thinking...
    If I get a molex splitter 1-to-2 and I take the 12v+ and GND , make it a DC make connector and plug it to the screen.
    Is it OK??? will it work??? what DC connector match??(2.1mm or 2.5mm)
    the screen power is: 11-24V so if I plug the 12 its suppos to work.

    http://cgi.ebay.com/2-Molex-4-pin-po...QQcmdZViewItem (molex splitter)

    http://cgi.ebay.com/8x-2.5mm-DC-Male...30136001r31029 (DC connector to screen)


    Im just to making sure that Im getting the info right for a succesfule project

    If I didnt wright enough, tell me I try to give more so you can help me in the best way.

    Thank... really!

    Easier solution:
    Since the monitor has a built-in regulator (it accepts 11-24vDC), just wire the LCD to the car's electrical on an ignition-controlled line.
    When the ignition is hot, the LCD will be on, unless you turn the LCD off, of course.

    There will be times (such as during engine crank) when the voltage drops below the minimum required for the LCD. IT will power off during those times, but they are short lived.
    Have you looked in the FAQ yet?
    How about the Wiki?

    first of all, thank you.
    now I can go forward with the questions...

    How do I connect the DC-to-DC to my car?
    Do I connect it directly to battery and do I need a fuse, if so what kind of fuse and where to put it?

    Is it an easier way for me not cabling the battery directly and find the power on the back of the car panel?

    They come with a manual. Read it.
    Hell, you can read the manual before you purchase the PSU, so you can know what you're dealing with.

    Do I connect it directly to battery and do I need a fuse, if so what kind of fuse and where to put it?
    Yes and yes.
    ANYTHING that is connected to the battery should be fused as close to the battery as possible. That's standard safety practice.

    Is it an easier way for me not cabling the battery directly and find the power on the back of the car panel?
    Not really.

    This will do the work? if so, how do I put it between the car battery and the DC-to-DC controller?
    (Whats the difference between an ATM fuse and an ATC fuse?)

    Another question:
    If I want to add a wheel so I could control the volume or scroll up\down the menu,
    How do I add it?

    Is it OK to use the Fusion Brain for it? (and to add features as I like)

    thank you very much =] !!
    Its help me understand what is it possible to me to do on the car and what are my limitations.
