Vibrating pixel mirror

This object translates vibration into visual output through a grid of mirrored disks. It is configured similarly to an LED display but instead of LEDs turning off and on, the mirrors can be activated to distort the reflected image. This final prototype, reflects a great deal of experimentation with material and construction. There is further potential for expanding the concept to a larger scale. A larger grid of these “pixels” would allow for more complex animations and could also incorporate sound and movement-reactive features for a more immersive and engaging experience.

The transitions between these parts are facilitated by additional pieces of laser cut acrylic.

The vibe motors are routed to the Arduino Uno through two 75HC595 Shift registers. The wiring diagram for this along with some basic sample code can be found here:
