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.

I've definitely followed a lot of these different projects, I would love something that would improve my sorting/organization by 50%. Hopefully someone open sources a project at some point and then we can all contribute where we can.

I've been toying with that but it is a lot of work and the initial outlay is probably well beyond what any normal person would be willing to put towards that goal. I've built one that worked remarkably well but it was huge and pretty finicky to keep running. Doing this properly is a $200K and up project for the first one and probably $10K or thereabouts for every one after that first one. Based on V2 (V1 was built of Lego and just a POC) I do have a pretty good idea of where the problems lie (and they likely are not what you think they are) and what to do about them.
