LED Globe

-Welcome-

The purpose of the LED Globe is to build a 3D POV system that can project text and images to the audience. To do this, We have 90 LEDs mounted onto a ring that spins fast enough to fool the eyes and display an image that the eye can see. The LED globe will be controlled via bluetooth and will have the ability to display images sent through commands from the bluetooth device.

The goal of this project is to design a persistence of vision spinning LED Globe, which uses a combination of phi phenomenon and beta movement. The LEDs will be mounted on a ring like structure, which will be spun at a certain angular velocity. The series of LEDs will be controlled by a microcontroller, which will be programmed to individually turn on and off the LEDs at a certain time in space to give the illusion of an image, which seems to be suspended in midair in the shape of a globe. The LED globe will be interfaced with Bluetooth technology so that a user can input a text or image and have it displayed on the LED globe.
