555 solution
from what i get from your problem, I think a simple monostable set up of a 555 timer may save the problem. The time delay is easily calculated with the formula: time constant = C1 * R1, a time constant is the amount of time a capacitor takes to charge something like 63.2% of the remaining charge. A 555 triggers at 2/3 of vcc (with a 9v power to chip itll trigger when capacitor is at 6 volts) adjust it like you need...
If youre not a techno-peasant or anything, sorry, im just a student in electronics so i try to explain it in simplest term, i hope that helps.
