Complete circuit RESET

[Demon]

The purpose of this circuit is to provide sufficient time for the PICs and LCDs to make a complete reset once powered down and back up.

seems an awful lot of circuitry to achieve not a lot, would it not be easier to turn it off, count to 3 turn it on again :D

for all that work i would expect at least a single button on/off facility

[Demon]

Yeah, that would work, but I thought this was cool with the delay. :D

And I've never touched a 555 or 7404, so it was a learning experience.

I like this idea

Where would a load go on this circuit (LCDs and other PICs)?

[richard]

Anywhere off the mosfet drain or the regulator, it's just a switch
