Ideally using a 556 chip I'm trying to setup a circuit that:
a) when circuit is powered on it triggers a one-shot pulse on the 556's A side.
b) when the same circuit looses power the 556's B side is triggered.
Circuit voltage should be 5 Vdc (optionally 12 Vdc) and pulse length should be adjustable (1-15 seconds).
