I've tried the no motor thing, but gave up after I could'nt get it to work. The
pulling the ball to the side was one of the first things that I tried, but there
are too many things that were uncontrollable. For instance, the direction the
metal 'poles' of the ball are facing effects the distance from which the magnet
will pull on it. Once you can get the ball to be pulled every time, getting it
pulled far enough for a light sensor to read it without it getting stuck to the
magnet is the next challenge.
I'm satisfied with my design- it works and I'm afraid it will stop working if I
change it. :-)
