Hello,
I have a circut that I found on this forum, that I don't want to keep powered up, rather I'd like the power to be switched on via the same switch that triggers the timer delay. I thought that if I introduced a 50ms delay to powering up the 555-2 and that if the Frequency of the 555-1 clock is high enough, then the circuit would still generate a 'random' delay anyays due to the hopefully insconsistent (tolerance) behaviour of a capacitor in serises with a resistor used to delay the power of 555-2 by 50msec or so. I was thinking at 3.9K resistor and a 4.47uF capacitor to ground the LM555-2 for 50-60msec.
Is that a possible route?
The circuit:

Basically I'd like the ON/Off switch to trigger the random delay without a momentary-on switch, hence only one shot at it until powered off manually.
Thanks,
Mihai
