    Power Options?

    Hello All ...

    I have started to research into CarPuters. Love the idea .. huge geek here! For researching these forums for the last few hours have have seen that I have 2 mabey 3 options.

    1.) Trunk PC
    2.) Glove Box
    3.) Dash.

    Im vearing away from the dash, so my question is with the first 2 options (trunk and glove) most likely powering and ATX/Mini-ATX motherboard what is ther best way to power them ?

    Inverter, Dc-DC, Etc.
    And with each of those hos does it get wired in?
    Directly to the batter, trunch power etc.

    Any help is greatly appricated!

    Thanks,

    dc2dc, to the battery via a switch and fuse.

    But "best" option is very subjective, you'll get lots of opinions. Does best mean smallest, most efficient, cheapest, most available?

    I you want cheapest, inverter + conventional ATX power supply is good.

    Positive to positive, negative to negative. Switch and fuse the positive. Make sure it's a good fat wire capable of taking the amps.

    O Man!

    Well ... This seems a little out of the scope of my ability .. need to plan this out well ... well the inverter i have has a sig. lighter connection on the end. So I should cut that off and wire those wires (with wires that can handel the V/watts to the batter? Correct ?

    If you open up the cig. adapter, you will see two wires, the one that goes to the very tip of the adapter is your positive, the one that runs to the side contact(s) is your ground. Just run the positive to the + on your battery and the negative either to a solid piece of metal, or to the - on your battery. OR you can even just tap into a fuse at your fusebox for your positive.
