Project Overview

We are attempting to create a spinning LED display capable of displaying 3D objects from all directions on a cylindrical shape. Our display can include basic shapes such as cubes, tetrahedrons, and spheres. Finally, our display will be able to animate such shapes.

Objectives

1. Design a mechanically robust device that will house the components including Arduino, batteries, and LEDs.
2. Position each component so the device is capable of displaying basic 3D objects on a cylindrical volume
3. Develop an algorithm to control when each LED turns on and off during the display cycle

Challenges

• Having a mechanical design that has a center of mass around the axis of rotation
• Mount the device on a motor
• Build a device so the wires are not entangled while device is spinning
• Wire connections do not break while device is spinning
• Ensure that device spins at constant rate
• Determine ideal rpm for device for visual display
• Mounting battery and Arduino on the spinning portion of the device
• Mounting Frame unto the motor
