Hi All, This is an on-going project that do not have a clear finish date. Most of it is think through aside the connections for the Battery & Ignitor extension. (most probably banana plugs) Not being a programmer myself, here is a few iteration of the firmware... Some milling of the box faceplate... I created a GitHub for the code and it's not 100% clean at the moment so sorry about it. DiaLFonZo/RocketLauncher To make wiring a bit easier, i've made a PCB as well but i made a mistake in the mounting hole dimensions. It doesn't fit the box pegs but i will find a solution.
