Hello I need help,
Trying to make a propane oxygen machine gun for a Halloween project and need help with the cycling board.
I need a switch two 12dc solenoids and one 12v motorcycle coil on and off at various rates.
Is there anything out there that is currently available already made?
Is there an easy circuit using a 555 timer?
I need the solenoids to open first and on the next cycle I need the coil fire.
I need to change the cycle rate and duty cycle of the pulse driving the solenoids and coil .
..Attached is a simple diagram
Any help would be welcomed
