A few photos of my progress to-date on an electronics bay build for an L3 attempt this Spring (COVID-19 permitting). The rocket is an Ultimate Wildman, so I have tons of room.
View showing the back side of sled, showing GoPro Hero9 and two-part battery pack that snugs-up against the sled, housing two LiPOs. PCB on bulkhead is simply there to wire up to the terminal blocks for primary and redundant charges for the main parachute.
Better view of top bulkhead. Epoxy is securing the terminal blocks (they're soldered into the PCB, but...) and also covering the wires soldered here that come from the terminal blocks on the electronics bay PCB. I'm using large Rocket Junkies charge canisters for the main parachute deployment.
Bottom half of the electronics bay main PCB. 3W 1.6Ω resistors with pulse rating are used as a "just in case" protection for altimeter outputs.
Bulkhead for the drogue side of the electronics bay. I designed these charge canisters and had them fabricated. They can hold a LOT of BP.
Window for GoPro camera has been epoxied around its perimeter. Finally I can justify the band clamp I bought!
Inside view of the electronics bay coupler showing the retention ring for the window assembly.
Last, but not least... the tracker mount for the nosecone. I gotta find this bird!
