I've seen some RE efforts for the MFT mount yes, I have not yet tried hooking up a logic analyzer to mine though.
The official raspberry pi 5" screen v2 is portrait orientation (720x1280). The one I'm using now is from waveshare and is 1024x600, so landscape orientation so I can have the video stream fully hardware accelerated.

Maybe it works at the commands at the top here: https://leste.maemo.org/User:Sicelo/Snippets
I guess your issue is that the USB port isn't in host mode so the USB device won't get recognized. This force-enables it, because the n900 never had proper OTG support

and switched back to my generic PLA roll and it prints perfectly again. I also got a filament dryer today so maybe that'll help

yeah a K2. It's only doing this with two rolls of filament though.
I have one roll of random PLA and one of hyper PLA that work perfectly. And I have two rolls now that do this, also one generic PLA and this blue one is a roll of Hyper PLA straight from the sealed package

It's a bit ironic that the audio is crap when talking about the new audio stuff for FOSDEM but that's what you get for ad-hoc plugging in another microphone and not setting the levels.

Got the full-color YUV preview pipeline working in Megapixels 2, Should help a lot on the platforms where getting bayer-encoded camera streams is not working. This means postprocessing isn't really possible but it's better than nothing. Here running with an UVC webcam for testing.

Here's postprocessd from #megapixels applying lens distortion and vignetting correction (the wrong values to make it more visible when testing)
