Fibonacci512 is a giant, beautiful, sound-reactive 320mm disc with 512 SK9822 2020 HDR RGB LEDs surface mounted in a Fibonacci distribution.

Fibonacci512 is a giant, beautiful, sound-reactive 320mm circular disc with 512 RGB LEDs surface mounted in a Fibonacci distribution. Swirling and pulsing like a colorful galaxy, it's mesmerizing to …

It consists of 512 SK9822-EC20 2020 HDR RGB LEDs, arranged into a circular Fermat's spiral pattern.

I have created several LED art pieces in Fibonacci patterns. They are all very labor intensive to create, and so are fairly expensive and limited in quantity. I wanted to come up with a Fibonacci layout that was at least slightly easier to create, and therefore more affordable.

I have RGB LEDs in just about every form they come: strips, strings, rings, discs, etc. The LEDs on most discs are arranged in very regular rings. Fibonacci512 is different. The LEDs are arranged in a Fibonacci distribution. The makes the layout very organic and seemingly messy. But with the proper animation, spiral patterns emerge with spectacular results.

It's controlled via a Pixelblaze controller and includes a Sensor Expansion Board that makes it sound-reactive. It includes patterns that can pulse along to the beat of your favorite music.

Each of the 512 SK9822-EC20 2020 HDR RGB LEDs has its own decoupling capacitor built in. The top and bottom of the PCB are large 5V and GND planes, to allow for the large amount of current required by the 512 LEDs. The PCB is split into four separate data lines to allow for higher frame rates when driven by a microcontroller that supports the FastLED library's parallel output, such as ESP8266, ESP32, Teensy, etc. The max theoretical frame rate with four way parallel output is ~260 FPS. Each of the four data lines has a separate four-pin headers provided for 5V, Data In (to the section), Data Out (from the previous section) and GND. The last Data Out pin can be used to connect to even more LEDs. There are also small jumper solder pads that can be bridged to drive the whole panel with a single pin (max ~65 FPS), or two pins (max 130 FPS).

Amazing Light Art Piece

I love this piece of art. It's mesmerizing to watch all the different patterns. The animations are super fluid and the default settings are spot on for my environment (small bedroom/office with natural light coming in from two windows).

The only thing I would change about this would be to make the keyhole a little larger to accommodate my preferred wall mounting (Hangman Gold Bear Claw Hangers).

I'm super impressed and enamored with this piece of art!
