I wanted a model rocket launch controller that looked the part, so I designed one. Using Fusion 360 it was not that difficult. The design features a key style power switch with a DC voltmeter to show battery power, a toggle arming switch, continuity indicator light for proper connection to your igniter, and finally a light-up arcade button to as the firing switch.
