(...) When you do pointer arithmatic, you work in increments of what the pointer points to. So if you have a pointer to an int, as in the above example, when you add one to it, you actually make it point to the next int, not the next byte or word. (...)

Just a suggestion but you could mount a Hall effect sensor somewhere near a rotating rounded part on the cage and glue a small piece of magnet to the rounded part.
