    This is JUST a delayed turn off.
    What sort of a delay Turn Off will this provide ? I'm looking for maybe 5 minutes. I have a CarPC made from an Atom based Thin Client PC equipped with an SSD. I have it connected directly to the 12v via an Auto Relay as in the picture and it works well but I would like to set it up with a Delay Shut Down of maybe 5 mins so that, if I went into a petrol station, turning off the ignition would leave the unit powered up long enough for me to get back to the car with the PC still on.

    For such long delays you'd need a FET.

    Have a look at's OFF After Delay Switch by Mosfet.
    The written understand difficult is, but IMO the prick is made a cross.
