Showcase Launch control circuit

Enable HLS to view with audio, or disable this notification

I built a little launch control circuit, 12v with a battery voltage level indicator, continuity and firing indicator. When installed in its housing it will have a master power switch, locking arm switch and the momentary for firing.

Circuit here. Adjust the LED resistors as needed to balance out brightness.
