We used a recycled stepper motor from an old printer as the motion source, attaching a CD clip to it so that we could make the CDs rotate at a stable velocity. The CDs were completed with a sticked paper with classical and brand-new phenakistoscope patterns.
By synchronizing the strobe frequency of a white led stripe with the motor rotation, we accomplish the image-in-motion effect on the eye.
We used an Arduino nano for the overall control of the pots, the motor, the leds…. and you can download the full code here:
