There's a number of ways to count the balls that I've seen (mechanical, using a
light sensor, and in one case timing the whgole loop by using the "steel"
dragons egg from the Harry Potter set:

But I don't think I've seen anything displaying them on the computer (instead of
the RCX or NXT). Come to think of it, since the NXT can communicate to the PC
via BT (Bluetooth), it should be possible to have a NXT-based GBC module that
counts balls, using BT to communicate them to a PC for display. Actually, you
could also have a NXT-based counter that communicates with a different NXT-based
switching module, so if a section of the GBC stops working (no balls coming
through) it signals the upstream switching module to shut down that branch
automatically. Or "pages" a human who's wearing an NXT on their hip to come and
fix things, etc.

| (...) The idea of displaying the ball count on the "big screen" is for show reasons. Of course it's easier to display it on the RCX or NXT, but it's not easy to read for a crowd of childrens :-) I also thought of using seven-segments LED digits (...)

| Scusate il titolo ambiguo :-) Ho una piccola scheda di interfaccia per PC che si può usare ad esempio per collegare i sensori Lego al computer. Se qualcuno ha un portatile che gli avanza, possiamo usarlo per contare le palline del GBC e mostrare il (...) (18 years ago, 7-Feb-07, to lugnet.org.it.itlug)
