    Lightbulb Powering Touch Screen from 12V rails on PSU

    Hi
    I have just purchased a liliput 619GL-70NP/C/T touch screen:
    http://www.allcam.biz/catalog/produc...products_id=99

    I have done some research and powering it from my M4-ATX PSU seems like the best option. The only thing is, I don't know how :S.

    I know that I need to hook it up to the yellow and black wires, but if you look at the link, there is a cigarette lighter power cable and a wall power cable.


    Do I need to use any of these power cables? If so, do I just cut into the wire and hook it up to the PSU? and if it's the cigarette light power cable, what side of the 'Power Filter' do I cut?

    Thanks in advanced
    JM

    My educated guess of what I must do is:
    1) Use the cigarette lighter power cable.
    2) Cut the wire between the 'Power Filter and cigarette lighter plug.
    3) Try and find which wire is positive and which is negative (hopefully someone can tell me ) and attach the positive to the yellow wire on PSU and negative to black wire on PSU.
    4) Turn on computer and pray.

    lol, solved my own question.
    You do use the cigarette lighter cable. The middle part is the +12V and the out part is the ground. So I just hooked them up as I said above and wala. It powers as I turn on my PC .
