Needed: a sensor component


#1

The most fun thing that I’d like to see added to the TT repertoire is a sensor, so
it would be possible to sort balls into red and blue, for example. The sensor
would have to be in keeping with the spirit of the device, of course, so the
sorting couldn’t really be by color; but how about magnetism? Instead of
red and blue balls which are slightly magnetic, how about yellow and green
balls which have the same weight and diameter. I’m sure there must be an
suitable pair of ferrous and nonferrous alloys with the same weight.

I was thinking about something like that. Ever played Manufactoria? You could make things significantly more challenging with 4 colors of balls. Thanks or the idea, Dave!
