Lego Great Ball Contraption Revisited

A Great Ball Contraption loop was assembled on FreeLug booth during LegoWorld 2005. Thanks to a strong ItLug participation it featured 18 modules at most (Italian team had to leave on Monday morning).

The GBC worked during the 6 event days, 7 hours per day. Reliability was very good – except some errant balls of course. At the end, we noticed some gears wear and stains of black paint from soccer balls on many modules but nothing serious. My Monitor module (to be documented here later) showed that about 15 000 balls travelled the loop each day, at an average rate of 0.67 balls per second.
