I made a simple ignition system using two 18650 batteries and a few other switches. It’s dead simple, which is good for safety. You just have to insert and turn a key, turn on the toggle switch, and then press and hold the button to launch. I’ll be honest here: I did NOT need to spend as much time on this as I did. I spent a good couple of days looking for and sourcing the nicest-feeling most authoritative switches possible. That being said, this box is an absolute joy to use. every click and press has an excellent tactile feel and makes the process of launching a rocket that much more enjoyable. Miles better than jamming a paperclip into Estes’s little 3V ignitor system 😛
