  • Mounting computer in a trunk

    Are there any issues to be aware of when running DVI and USB cables over a distance of, say, 12 or 15 feet from a trunk installed computer to a monitor in the dash?

    Run the signal cables down one side of the car and power cables down the other side to minimize the possibility of EMI.
    Some say that high-quality cables are better than cheapie ones. Some use cheapie cables with no problems. Be prepared to try different cables for the best results.
    Have you looked in the FAQ yet?
    How about the Wiki?

      Your monitor will function just fine if you stay at or under 15 ft. For other devices, however, at that kind of length you'll need a powered hub on the other end. The max length of a USB cable is 5m (for full speed devices) or 3m (for low speed devices) - USB devices won't get enough power if you go longer than that without a powered hub on the other end.

          Is there a common equation for voltage and current drop over a wire length?

            There is an equation, yes. V = (25 x I x L) / CM
            This site explains it: http://www.stealth316.com/2-wire-resistance.htm
            It also has a handy calculator for voltage drop.
