Great Ball Counter

A counter made of 7-segment-displays that is easy to ready. Additionally it features a gauge showing the current ball flow (0 .. 60 bps) as well as a semaphore indicating if still balls are coming (white circle signal up) or no balls have been seen for more than 35 s (red square signal up).
