    odd project... a backpack computer

    hi all, i am thinking of doing a project for a friend of mine, they want to have a computer installed in a backpack, powered by a battery so that they can record video with it.

    the system will be:
    little valley mobo
    opus 120
    a 160gb sata 2.5" hard drive
    no monitor
    some kind of small camera and mic (yet to be determined)

    with a setup that small, what kind of 12v batteries should i be looking at? i need for it to be able to run for about 3 to 4 hours per charge while still being as light as possible.

    sorry for the lack of details, the planning phase has just begun.

    thanks,
    David

    Question:

    Why wouldn't you just use a laptop setup?

    Get one of the newer, smaller units and most of your issues seem to be worked out except battery life...............and you can us eit to veiw or edit the video later in the hotel or wherever you are.

    Or get a HDD or DVD camcorder, a remote pencil camera and a couple spare batteries would seem another sensible way to go.

    Just wondering.

    On a laptop, the monitor (and backlight) uses most of the battery. With the lid closed (appears you want a hidden camera setup and will not be monitored) you should get a lot more than 3 hours.
    My opinion is my own.

    i had thought of the laptop idea, but i figured it would get too hot in the bag (mine always get really hot in there after only a few minutes) so i thought a well ventilated case would be better. how hot can a laptop usually get before damaging it? also, what would a decent small video capture device for a laptop be?

    thanks for any suggestions,
    david

    you could always add a vent fan if you where really worried abotu it id say take a backpack build a box inside of it with a vent out the top so that you get fresh air

    it be WAY easier than doign the computer
