A lot of pictures and full menu map And MS paint wiring diagrams (1st camera) https://github.com/jdc-cunningham/pi-zero-hq-cam/tree/master...

Another good link https://www.youtube.com/watch?v=6QQx0G5MR3k Trying to find this one where a guy made a sensor stack from scratch it wasn't great like 1 MP but still amazing This one open source USB 3 camera damn! https://www.circuitvalley.com/2022/06/pensource-usb-c-indust...
Breaking Taps had a video not long ago covering his efforts to design and fab his own image sensor, though it didn't work and it wouldn't have been anywhere near 1MP even if it had.

Nice work! What's the boot time like? I didn't see it in your Medium page.
I use systemd to run main.py let me time it real quick.
Edit: I was off, it's 40 seconds when the intro animation starts playing.
This is why the camera spends most of its time in the home screen state until you're ready to take a photo which is when the live pass through plays or while recording a video (allows you to change focus/aperture while filming). That also conserves power since it has the highest current draw while recording/showing a live preview.
The official forums are surprisingly devoid of anyone trying this, which is not super encouraging.
I'd really like to experiment in doing some underwater VR180 photo/videography, I promise to share the results if anyone has any useful pointers (not strictly rPi related, but other platforms are even less promising. Happy for any unexpected hints tho!)
(Sorry for the barely-on-topic (if not outright offtopic)) but this is a rare chance to tap into HN's hive mind on this particular issue due to a Pi-camera related thread on the front page.
I just really wish Raspberry Pi would come out with a truly HQ camera with a full frame 35mm sensor, or at least an APS-C sensor. I'd pay $1000-1500 for it, just to have something as good as a full frame camera but programmable and hackable. I would love to build a full frame mirrorless camera that runs my own UI. I'm pretty sure I could code a much more advanced UI than Sony or Canon. Their current HQ camera is more…
As I understand things, the Pi has a single lane of CSI at maybe 1.5 Gbps. That's enough for 1080p video, it's not enough for 4k video.
A high-end smartphone, on the other hand, has more like 5 Gbps of bandwidth to the camera, and the processing power needed to deal with that much data. But the device cost is 10x what an RPi costs, so they can afford it.
Did anyone have any luck capturing stereoscopic videos at any meaningful quality? This used to be only possible with the Pi Compute module (unobtainium for a very long time) but the Pi5 finally exposes both camera ports.... while also dropping hardware encoding, which is likely to be a huge roadblock since I doubt there's enough CPU power + bandwidth to compress 2 4K streams at 60fps in realtime and store it. And I'd…
But the software has a ways to go, it seems. I wonder if a potential CM5 would be able to stream the two video feeds better than the CM4.

It's slow haha. Faster on the Pi Zero 2 with bookworm. I think it's 20-30 seconds. I use systemd to run main.py let me time it real quick.

The best hardware option currently is StereoPi: https://stereopi.com But the software has a ways to go, it seems. I wonder if a potential CM5 would be able to stream the two video feeds better than the CM4.
I had read and promptly forgotten about StereoPi, I'll give it another look now that CM4s are no longer impossible to get.
Regarding CM5... who knows (Probably you? :-) ) but given the loss of hardware encoding I'm keeping my expectations low for video at any decent resolution and framerate (unfortunately a 2x2064x2208x60fps video is close to 1.5 GB per second, and at 72fps (which should really be a minimum) it's 2GB/sec, hardly the realm of software encoding, unless I want to bring an Epyc/Threadripper underwater and somehow power it from a battery.)

Try alpine to slim it down?
