Giday everybody,
Hoping the collective mind of this forum can steer me in the right direction.
As the heading says, is been years since i did this,(TAFE).
Objective: looking to fire 2 LPG fuelled bird scare cannons using leftover car parts.
Parts: 1 DIS ignition module (that I have piggy backed on another motor and had sparking),
2 LS1 style coils (coil on plug), to fire cannons.
DIS supplies constant +12V and a switched ground. And the LS1 coils need +5V to trigger.
My thoughts so far; see .png below.
sorry, just seen that this sketch is old. Ignore the part marked DIS, and every thing after the 7474 chip
My question is am I heading in the right direction with the wiring of 7474 (or similar) so as to 1/2 the original clock streem, and alternate the o/p, you know,fire 1,fire 2,fire 1,fire 2,etc.....
