Here's what I'd like to do but do not know how:
When a line goes from unpowered to powered, I want to briefly connect two leads (as to mimic a momentary pushbutton) and then have them disconnected.
Actual scenario is this:
I'm going to rig my PB Superflash to be supplied by my 14.4V li-ion battery using a 3 pin voltage regulator to 3V. When I supply power to the Superflash, I want it to automatically turn on. In order to this, I'd have to simulate a push of its momentary pushbutton. I will solder directly to the pushbutton contacts but need the timer circuit or whatever mechanism to simulate the press.
How would this be done? Schematic?
