random motion gearbox
i have been exploring wast of creating a random motion from a gearbox, i need this for a segment of a kinetic work i have been doing for some time now. random motion seems somewhat difficult to achieve so i came to the conclusion of using magnets! the gearbox i am working on at the moment works by orbiting one magnet around the other, the central magnet spins the output shaft while the orbiting magnet performs many rotations around the central magnet tugging it to different positions giving an almost random movement (patterns can be found). i was wondering if there were other maybe more effective methods of achieving random patterns of movement without the use of electronics.
