Death Star Brought to Life Through Persistence of Vision #piday #raspberrypi @Raspberry_Pi
Students at the School of Electronic and Electrical Engineering program at the University of Leeds developed a POV Globe modeled after Death Star. We’ve shared about this before, but here’s how they did it. From makerflux:
As well as giving the illusion of a miniature Death Star, the globe can be programmed to project many different images using a raspberry Pi that is mounted in the centre of a transparent sphere. The Raspberry Pi sends signals to a ring of RGB LEDs that are rotated at high-speed (300 rpm)…Because of the speed of rotation and the Raspberry Pi’s ability to change the colours of the LEDs very quickly, our brains interpret the projection of light on the surface of the sphere as a solid image. The whole thing can be controlled wirelessly via an iPad…
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
