I'm attempting to build a coffee bean distributor that can exactly measure out beans into a cup for my morning espresso.
It's really an excuse to get started with things like hardware, 3D printing, and embedded development - I've never done anything in that world before, and its been really exciting to get into! I've just started, so hopefully I'll have a better update next month.
Counting the beans, or by weight? (Or I suppose you could 3D scan each bean as it goes past to measure volume for extra credit)
I won't be getting extra credit! My plan right now is to go by weight, and my first attempt is going to have beans in a hopper, moved by an auger that slows down as it approaches the target weight ( ideally moving a bean at a time at the end, to get within a bean of the goal (ideally).
That sounds fun! Very cool project.
By weight, or by bean? heh
