    New shutdown controller - software

    This is a solution everybody can do I think .
    I wrote this prog to shutdown/hibernate your computer when you short pin 4 and 8 on the comport. There are instructions in the zip file.
    Use it as much as you want and tell me if I should add something or do something different.

    Works great!!! I was thinking that if you could some how have the serial port send out another signal a little bit after the shutdown occurs that could control a relay that could turn off an inverter. That would be a kick *** program for all of us with inverters. Nice work.

    Take a relay that is triggered by the 12V of your power supply and by the ACC line from your car, you have to put a diode in between, and feed the Inverter/PSU thru it. And set the motherboard BIOS to startup after powerloss.

    This is a very good function. I am running my carputer on EPIA-TC10000 and it has onboard dc-dc with two pin 12V output. Maybe this could control the relay?

    I'm assuming you couldn't use this if you have a GPS already on the com port? or can it co-exist with other equipment?

    CRCinAU, it wont work to have it on the same comport, but there´s mostly 2 comports on every motherboards, you just need a cable for it, no need for an extra card or something, check in your motherboard manual

    Updated shutdown controller:

    Shutdown Controller

    It will now pause winamp and turn off your screen when you short Pin 4 - 8.

    I use it like this:

    When I turn off my car it will pause winamp and turn off my screen but leave my computer running for 10 min, if I get back before 10 min it will directly unpause winamp and turn on my screen.
