Thread: Can anyone help me with a time-delay circuit?

Hi all, was wondering if anyone can help me with a time-delay circuit, at least I think that is what I need.
I want to be able to power my Asus eeepc from a cig lighter adapter, from the ignition key (which is what I have already done at the moment)
but I want to be able to momentarily cut the power for about 10-15-secs when I turn the ignition off, so that after 10-15secs the power is restored to the eeepc. Any ideas welcome.
