I have been increasingly interested in an automatic LEGO sorting machine. I buy $1000's of loose pieces and large sets. Often times the sorting takes way more time than I want to put into it though.
So far the best I have come up with is a variable sized screen method. Similar to Box 4 Blox. It still takes a good deal of time to really bulk sort bricks though. I've considered that maybe there are ways to vibrate the screens to speed up the process of them dropping through to lower sizes.
Anyone have ideas for new creative ways to mechanically sort into categories like: small bricks, large bricks, small plates, large plates, tiles, panels, studs, technic pieces, misc small parts?
I will post some pics of my crude sorting screens
