We’ve all seen geodesic domes in one form or another, whether as a modern experiment, as housing from a bygone era, or perhaps as a gigantic structure in Orlando (technically a geodesic sphere). Jon Bumstead apparently wasn’t satisfied with current dome options, and instead created his own, integrating elements from programmable LED tables to make it interactive.
The resulting build is quite spectacular. Each triangular section able to be lit up with an RGB LED, and further information is output to five MIDI signals in order to produce sound. This means that up to five people can play the dome as an instrument simultaneously. If that wasn’t enough, the Arduino Uno-based dome is programmed to play a version of Simon or Pong, and can be set up to display a light show!
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
