Congrats on your build.
I've also built a camera, with the BGA/sensor mounted directly on my board, with good old CHMT36VA. With a double-sided PCB this was pushing the limits of both OSHPark manufacturing process and PCB/chip alignment during pick & place. Initially my yield was around 50% :-/
And the sunlight issues were instant and horrible problem. Unlike your aluminum casing, initially, my was SLA printed - transparent across the spectrum. Including the camera box. Regardless of what I've tried (for example, two layers - metallic coating and pure black paint that telescope enthusiast are using), I couldn't get rid of some level of sunlight effects.
Regretfully, had to shelf this project :-/. AI started exploding and playing with camera designs suddenly became less of a focus.
- davekeck 3y agoSounds like our projects have a lot in common. I had my boards made in China but the yield was also not great (~80%). I had to repair a lot of them after they arrived, but from what I learned I think I could get close to a 100% yield if I do another run. The sun sure is pervasive! My early enclosures were 3D printed too and had the same problem. I've had the same thoughts about AI many times while making this camera... making anything today that doesn't involve AI feels a little crazy.
