What I want to do or know
I've seen some of the really great work by @cristoforetti and the #webvalley group -- which I was lucky enough to help a bit on -- to build a version of our spectrometry kits around the camera from a Raspberry Pi mini computer board.
On a hardware basis, this'd hopefully be as simple as gluing the Raspberry Pi camera ($40 with the Pi Zero version board on Adafruit) in place of the webcam that comes with the kit, shown above.
Raspberry Pi cameras can have auto exposure/gain compensation shut off, and a specific shutter speed manually set. This could do a lot to improve #exposure-calibration, perhaps adding to work by @stoft on #gain-correction.
Has anyone tried that?

Getting the software running could be harder -- the Raspberry Pi isn't like a USB webcam, and if you're using it with a monitor & mouse, I'm not sure the camera would show up like a USB camera in a browser.
Note: see possible solution with V4L2 library, below in comments!
Aside from uploading it as a still image, what more easier, simpler ways are there to use a Raspberry Pi-based camera using the live web interface at https://spectralworkbench.org/capture ?
