Considering adding camera support to Typica. Right now I have a camera mounted to the sightglass which is intended to feed into a separate box that processes the image and drives a 4-20mA current loop indicating the degree of roast, but if I cut out the separate box I could throw a lot more processing at that and probably expand the output range.

One trick here is that I'm tainted from having access to the proprietary code on that external box. Anything I did would be a rewrite since I don't like Python, but I can't un-see the domain expertise from the original code.
If I did this, I'd also want to add an on/off switch since there's a light and a fan attached to the camera that would always be on otherwise.
The other trick is that it's possible that code I wrote here would be of absolutely no use to anybody else at all. That camera I have is a prototype that I'm pretty sure hasn't been turned into a product yet.
