Launching a model rocket can be as simple as connecting 2 wires to a drill battery, but it doesn't look cool, and you must be close to the rocket itself because of the wires. Instead of doing that, I made a rocket launch terminal in a rugged waterproof case which communicates with a small rocket launcher using LoRa. The rocket is ignited using supercapacitors so that the whole system can be powered using a small 9V battery!
