Read More…Fibonacci32 is a beautiful 50mm circular disc with 34 WS2812B-Mini 3535 RGB LEDs surface mounted in a Fibonacci layout.
I decided to include 34 LEDs since it's a number in the Fibonacci sequence, only 2 away from 32, and there was room on the 50mm PCB. I'm calling it Fibonacci32 so that it fits in with the rest of the series.
Includes only the printed circuit board with LEDs, does not include parts that are required to assemble and run it (microcontroller, power supply, wires, etc). See below for recommended parts.
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 34 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 34 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.
