I built a dual axis laser pointer setup to play with my cat but she looks at the servo's too often because they're so noisy. I was wondering if I could use memory wire to control the laser pointer since it would be quieter. Now I'm wondering if these stepper motors might be a better alternative, maybe a third one against some sort of a spring loaded harness. Either way very cool, would be interesting to see if a third motor might have helped rather than relying on gravity and good behavior of the chalk pen.
