DomeStar is a PVC dome built with Teensy microcontrollers at the top, and a lot of LED strands running down the sides of the dome.
DomeStar is a beautiful, fully-interactive, spherical LED installation housed inside a PVC dome. One part installation, one part chill out space, one part high-energy dance floor. DomeStar invites guests to dance their blinkin’ faces off, then to lie down and look up as the complex visualizations warp, twist, shatter and throb around them, enveloping partygoers in a comforting aura of complex energy.
These LED strips are fun and glowy. There are 32 RGB LEDs per meter, and you can control each LED individually! Yes, that’s right, this is the digitally-addressable type of LED strip. You can set the color of each LED’s red, green and blue component with 7-bit PWM precision (so 21-bit color per pixel). The LEDs are controlled by shift-registers that are chained up down the strip so you can shorten or lengthen the strip. Only 2 digital output pins are required to send data down. The PWM is built into each chip so once you set the color you can stop talking to the strip and it will continue to PWM all the LEDs for you.
