The globes themselves are made from styrofoam cups and bowls stuck to- gether with a combination of solvent free adhesives. I read somewhere that you can produce cyanide by melting the foam with the wrong glue, so I guess you have to be a bit careful! There is a history of using styrofoam and even cups to create ‘artworks’ – thanks internet for reminding me how hard it is to do anything original! – there is a page of works here . I made a hole in each cup using a hollow punch, glued them to- gether and then pushed through a Ws2812 pixel through each one, around 80 pixels in each globe (there are a few slightly different shapes)
Each globe has a Raspberry Pi in it with a wi dongle and a usb soundcard. I am running the Satellite CCRMA image – the image is raspbian based with some op- timisations for use of audio as well as including Pure Data and Nodejs, both of which I used for this project. I’ve got mixed feelings about using the Pi for this kind of thing – its amazing that it works but it was a slightly painful development process
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
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.
