Ok after a little research on the 555 ci timer iIcame up with a couple things,
one, I will most likely be wiring the timer in a monostable, or one shot circuit.
two, it will need to run on nor more then 15v so a voltage regulator will be needed
last, I will really be needed help while figuring this out
I found a schematic used to delay voltage to a relay to trigger another circuit.(attached, the middle schematic about voltage remaining off for set delay)
I quickly made this circuit to figure it out it worked flawlessly, my time of 7 seconds was accurate and the 18 volts I had running through it went from zero to 18 after exactly 7 seconds. upon attempting to add Leds where i needed them ( master power and ready to fire indicator) the circuit began to malfunction. I also found that trying to substitute the relay control with what i needed would not work.
What i am asking is how would i modify this to achieve my above statement for an air cannon controller.
