Model Rocket Igniter Control
thingiverse
I built this rocket igniter control box for model rocketry, a project I'm excited to share with my kids. Growing up, I had an absolute blast with model rockets and I want the same experience for them. Unfortunately, most of my childhood equipment has disappeared over time, so I'm starting from scratch. Fortunately, I have access to a 3D printer, which allows me to save on costs. My goal was to create something that looks impressive and functions flawlessly. To give it a realistic feel, the igniter box is designed to resemble something you might find in a space program. It features a functional key that must be turned to operate. To launch a rocket, simply push the lever forward, and get ready for liftoff! The control box runs on two 18650 lithium batteries. When I was younger, I discovered that using more power resulted in better-performing igniters, faster launches, and even allowed me to reuse spent igniter wires by folding them in half and inserting them into rocket engines. This project is ongoing, but here are some features I plan to include: When connecting the leads to the igniter, a beeper will sound, alerting you that everything is connected correctly. For added safety, if the key is inserted while connecting the leads, it will lock out until the key and leads are removed and restarted. The buzzer will change from a rapid beep to a steady buzz when the key is armed after the leads have been connected.
