Model Rocket Launch Controller - Dual Circuit

Model Rocket Launch Controller – Dual Circuit, Key-Armed System This project is a purpose-built model rocket launch controller designed to provide safe, reliable ignition for single or dual rocket launches using commercially available igniters. The controller is powered by an internal 12 V lithium-ion battery protected by a 7.5 A inline fuse, providing ample current for short-duration ignition while maintaining electrical safety. The system supports one or two simultaneous launches via two independent ignition output circuits, allowing either individual or dual ignition from a single controller. Each ignition circuit is controlled by its own LED-illuminated safety switch, enabling the operator to positively enable or disable each launch channel independently. This provides an additional layer of control and prevents accidental ignition of an unintended circuit. Each circuit has been tested and can deliver 7 amps of current to the igniter. Each output circuit is also equipped with a ded
