This instructable guides you through the steps in building a ceiling-mounted light that controls thousands of addressable RGB LEDs, reacting to sound and creating visually spectacular animations. A project to inspire your night club with sound-reactive lights, or a project to create a soothing ambient light for your study. The possibilities for customization are endless if you can just write a bit of custom arduino code.
This project has been a collaboration with GitHub's @daterdots, and stands on the shoulders of giants like arduino, pjrc, and the fastled community.
The shape of the pendant is defined by the curvature of the LED strips as they are supported at a few places along the axis of the pendant. The top and bottom pendant supports are circular platforms that also house some of the system's embedded electronics. I like the simple cylinder shape we get from having only two support platforms - one at either end of the LED strip, but you can add rings at any point along the pendant's axis to control the curvature of the LEDs.
