Circuit I built into my transmitter to allow me to time shots fired.

Overall Layout of Circuit. Circuit uses 3 555 timing chips and a few logic 7400 chips, After a shot is fired bow or stern, the cicuit will flash a red LED to let me know I fired that specific cannon, when timing is completed, a buzzer will go off letting me know it is ok to fire again.

Main timing circuit board and logic chips, you can see the LED, in the left corner and the buzzer in the right corner.

Lights are visible when timing of curcuit is activated, buzzer will go off when LED goes out.

Resistors in back of TX to allow for delay time inbetween shots to be tuned.
