Would love to know if anyone has a reproducible sorting machine. Like schematics and/or parts list for a hopper and feeder and all the other parts. The most recent one in this list looks amazing but doesn’t share the actual specifics of the design. Daniel’s one from a few years ago (also linked in the list) is also great but it’s made out of Lego, using more Lego than my kids have to sort. Probably just a little too indulgent for my needs.
