I designed these centerpieces for a recent wedding. Each assembly consists of a small 4" screen that is connected to a small motor at the base of the unit. The screen displays a looped video and is able to rotate 360 degrees.
The base houses the motor, motor driver, a single board computer, battery pack and several other small components to run the unit.
The housing itself was 3D printed and all electrical components consisted of off the shelf parts.
