Fibonacci128 is a beautiful 86mm circular disc with 128 WS2812B-Mini 3535 RGB LEDs surface mounted in a Fibonacci layout.
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. Fibonacci64 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.
Each of the 128 WS2812B-Mini 3535 RGB LEDs has its own decoupling capacitor built in to reduce noise. The top and bottom of the PCB are large 5V and GND planes, to allow for the large amount of current required by the 128 LEDs. Two separate three-pin headers are provided. One for 5V, Data In, and GND, and the other for 5V, Data Out, and GND. The Data Out pin can be used to connect to even more LEDs.
The open case is built with 3mm black LED acrylic diffuser, black nylon M3 standoffs, black metal M3 screws, and 3D printed back plate with wall mounting hole. Available as kit or fully-assembled.
