Hey, very nice Mark! Warning, watching those little balls go around and around
in a creation of your own can be... very addictive :-)

Nifty. I wouldn't worry at all about having *too much* throughput; since the
overall rate is 1 bps, the modules upstream of yours will just be feeding yours
at a lower than its maximum rate. That's why the standard is written as being
"at least 1 bps". You could always use something like a flip-flop to split the
stream and even have your module feed part of its output back into itself. I
also suspect you could stretch this vertically into an oval by adding treads.

That's a rather coveted design charecteristic - "mil spec" modules tends to be
rather uncommon. One thing I can't see (yes, I went the all the deep links) is
how you keep balls from either being dragged under by the descending pins or
other wise "seal" the bottom so balls don't fall in. Or does the track itself
form the bottom of the input hopper system?

That's very good to hear. Perhaps this will end up in a train unloading module
(one of the tougher kind, due to the requirement to handle large pulses of balls
with high reliability). It's kind of neat to see it set up to feed itself as is,
however. Do you have video?
I can't wait to see more :-).
