People over the years have indeed added motors to their Rondinax machines. The typical motors seem to have been canibalized from chicken broilers. The problem is: One does not want a continuous movement but a jerky one to make sure that the flows are "random". The joy of the Rondinax is also its portability and small size and both of these get tossed out with a motor unless one makes something like a platform and a geared knob that allows the Ronidax to also be used "manual".
