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.


  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


  • 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


  • Mega Arduino: $0 - provided
  • Electrical Tape: $8.99 (w/out shipping fee) [1]
  • Insulated Copper Wires: $14.01 (w/out shipping) [2]
  • Stepper Motor[17hs13-0404s]: $0 - provided
  • Hot glue: $0 - provided
  • Soldering Tools: $0 - provided
  • 3D Printing material and 3D Printer: $0 - provided
  • AA batteries: $12.68 [3]
  • Battery holder: $0.99 [4]
  • LED strips x3: $24.95 x (5 - 2) = $74.85 [5] (we are buying 5 to get the discount and then reselling two, any additional fees excluding shipping fees may come out of our own expenses)

Total: $111.52
