Very cool. The vibration feeder reminds me of the time when I was building assembly lines, those feeders were always tricky to get right, even when feeding only a single type of part. We had bowl feeders, which feed and singulate simultaneously but that would be hard to do in Lego and impossible for multiple unknown part varieties.
