For my project, I am building a high voltage model rocket launch controller designed to be safer, more intentional and way cooler then the basic ones sold for $50 dollars. The goal is to make a controller that uses multiple safety steps before ignition can happen, including a key switch, flip- cover, continuity led, warning buzzer, momentary safety button, and a large red launch button. The schematic is built around a safety path. The key switch acts as the first lockout, making nobody random can use it. The wiring was most important due to needing to prove continuity by sending a small enough current not to set off the ignitor. after that, it was a series of setting roadblocks for the current, and allowing the full power to go through on all safeties were off. In overview, most controllers send about 2 amps due to that being only what is needed to set off the ignitor. Mine sends 6 amps practically exploding the ignitor getting a better rocket launch.
