Interactive Persistence of Vision Globe @raspberry_pi #piday #raspberrypi
This is a fun project from a mechanical engineering group at the University of Leeds. They even have a Nintendo simulator that can run through it! Very cool.
Four of us spent 15 weeks building an interactive globe from the ground up based around a Raspberry Pi dev board and a Xilinx Spartan 6 FPGA. The globe was build from entirely surface mount components and all the electronics (apart from the RasPi) were designed by us as part of the project. The Raspberry Pi is mounted at the centre of the display. It is then connected to the FPGA chip via its HDMI output, which is then decoded and converted into RGB data. The image is then scaled down to fit on the display.
The Raspberry Pi is controlled via an iPhone application that we wrote which connects via a Wi-Pi module. The Pi is setup as a router allowing multiple iOS devices to connect at the same time. There is a second Wi-Pi module which connects to eduroam for internet access.
We setup EmulationStation to run on the pi allowing games such as Mario to be played. We also created several applications our own, such as a photo builder app which allows photo collages to be put together and displayed. There is also a weather application.
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.
