  • idea on temp/direction/gas

    In my parents van(2000 doge caravan)they have a overhead unit that displays: temp/direction,current mpg,how many miles left on the tank,and i tihnk one other. I have also(sry cant find any of course)have seen these little screen that display temp and diretion(n,e,s,w) and threr just little screen and wondering if a could get a little screen mount it some where(gauge bezel)and the some how send current direction/ temp. There are endless possibilites such as sending(headlight on/off,door locks locked/unlocked)and so on and so forth. just wandering if anybody think this might be possible to have this and running realtime no delay.

    It is possible to have the temperature show up on a computer...easily with a thermo couple or interfacing a temperature probe with said computer. Keep in mind that you will need software/graphic interface to get the appropriate screen...anything is possible with enough money and time

      Hook up an LCD character display to the parallel port; there's various sizes of displays, and plenty of drivers that support them. If there's a spare temperature sensor input on the mobo, you can connect a thermistor to that http://www.k7v.com/probe.shtml.
      If you need more inputs, or to read voltages, the Labjack USB box has 8 analog inputs http://www.labjack.com for around $100.
