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.
The third one requires some explanation, but it's very reliable.
GBC modules that jam when too many balls arrive are always trying to funnel many
balls into a narrow output chute. If two balls arrive side by side, they block
each other from entering the chute, and any subsequent balls pile up in the
hopper and eventually overflow.
The solution is to change the direction the balls are heading once they enter
the hopper.
Make your hopper a wide ramp that slopes toward a second, narrow
one-ball-at-a-time ramp that is placed 90 degrees (perpendicular) to the wide
ramp. The incoming balls will roll en masse into the narrow chute on its long
side; they will no longer be trying to roll into the narrow chute one at a time
from its upper end. This arrangement can still overflow its hopper if the lower
end of the chute isn't dealing with the balls fast enough, but it won't jam --
the first ramp is too wide.
Moving 1x1 plates with just gravity won't be as easy as soccer balls unless the
ramps are pretty steep, but I think you can pull it off. You could still use a
tank tread as the narrow "chute"; you just need to have the hopper dump the
plates onto it sideways instead of from the end.

| (...) 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 (...) (16 years ago, 4-Jul-08, to lugnet.robotics)

| Maybe a look into actual GBC designs and their approaches to transportation might prove useful (?).
