Hello Jordan,
Thanks a lot for the tip! This is an amazinly simple and effective way to
serialize a ball flow. According to my experiments, there is a little thing to
add to your explanations: the narrow ramp level must be sufficiently lower than
the base of the wide ramp, or ball arcs can still build up.

| (...) Thank Rafe Donahue, actually. I learned about it from a math/statistics-based presentation about GBC modules he gave at BrickWorld 2007. If he didn't discover the technique himself, he at least documented it. :) I haven't seen a lot of modules (...) (16 years ago, 8-Jul-08, to lugnet.robotics)

| GBC module creators tend to independently reinvent the same hopper solutions used in factories. Some of them shake, many of them have an agitator spinning inside it to loosen the pieces, but the simplest just use gravity and a change of direction. (...)
