detecting the ball itself via reflected light

Across from the light sensor, two studs away, was a silver brick,

Now that is a nice solution, and not one I'd thought of. Not having the silver
brick, I could still use a (non-LEGO! Aaah!) solution of a small pice of
reflective tabe or something. Cool.

If the ball went into the hole, it rolled past a light sensor (old RCX version; is there a new nxt one?). Across from the (...) (18 years ago, 6-Sep-06, to lugnet.robotics)
