The project was originally launched a few years ago by a MEng student group consisting of Thomas Carpenter, Oliver Peel, Adam Clarkson, and Laurence Bird, with supervision from Craig Evans. It makes use of a ring of RGB LEDs, rotating on an axis at 300rpm, to display an image.
A Raspberry Pi sits within the rotating build, offering HDMI connectivity to allow images to be sent to the LEDs through a decoder.
Images can be sent to the globe from any smart device, allowing the engineer to display a map with their own chosen coordinates, visual temperature readings, etc. This makes the globe useful for marketing and education and entertainment.
