very cool. If you're looking for machines to add, it would be awesome to model a cheap roaster based on a popcorn popper since it is probably less reliable than commercial sample roasters (and might benefit from less trial-and-error). During my undergrad I made an arduino-controlled popcorn popper that connected to the open source artisan software: https://github.com/lukeinator42/coffee-roaster .

100% agree - each roaster is slightly different, with different measurement schemes and other device peculiarities. This makes sharing coffee roasting profiles basically impossible!

I'm also working on letting people upload their roast profiles for training and serving their own models (including a "library" of bean models!).

If I understand this correctly, calling it a "digital model" would be more appropriate. Digital twins require sensor input from a real system as well as the ability to alter the real system, not just prediction.

This is correct.

I overclocked the roaster and now the kitchen is gone: https://i.imgur.com/qRcGm64.png

(Nice work! This is really nifty. I wish I knew more about coffee so I could better understand the dynamics of the controls and how to achieve a perfect roast.)

Yeah, as shown it's just a bunch of models. The real magic happens when this is connected to hardware and we can do things like data assimilation and control.
