New altimeter mounting is ready now. Complete re-design that makes all the MMAS nonsense completely redundant. The MMAS mounted avionics were a neat idea but just didn't come out as nicely as I would have liked. Too many compromises to fit the available space of the 29mm tubes. I didn't like the venting, I didn't like the arming method, and I had my doubts about the strength of the altimeter mount.
I've designed a custom circuit board that mounts my Raven 4, an Eggfinder MiniWifi switch, and a battery. This all goes into a 3D printed housing that will mount to the inner wall of the body tube. Everything is self-contained including the charge wells. The e-matches are going to connect with molex mini-ft jr connectors so that I don't have to fiddle with screw connections or anything like that in the field. I can load this whole module separate from the rocket, then pre-flight will just consist of mounting in the rocket and connecting the e-matches. Arm on the pad with the wifi, and woosh goes the rocket.
