Fibonacci64 Nano is a tiny, beautiful 33mm circular disc with 64 SK6805-EC15 1.5mm RGB LEDs surface mounted in a Fibonacci layout.
It consists of 64 SK6805-EC15 1.5mm 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. 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.
The SK6805-EC15 each only consume a maximum of 15mA, and that's at 100% brightness, solid white color. That's only 960 mA for all 64 combined. They are still very bright, and I usually only run them at about 25% brightness. They're perfect for wearables, powered with LiPo batteries.
It has solder pads on the back that match the pinout of the QT Py by Adafruit, or XIAO by Seeed. It can be used by any microcontroller via the 5V, GND, and Data In pins. It also has a Data Out pad, for connecting more LEDs on the same data pin.
Three of the four mounting holes are surrounded by capacitive touch compatible pads. They're connected to the A0-A2 pads/pins on the QT Py footprint. The SAMD21 QT Py supports capacitive touch on these pins.
The open case is built with 3mm black LED acrylic diffuser and back plates, black nylon M2 standoffs, and M2 screws. Available as kit or fully-assembled.
Options available to purchase for additional amount:
The "Fully Assembled" option requires, but does not include, a USB-C cable and power source (USB port, AC power adapter, battery pack, etc).
If the "Fully Assembled" option is not chosen, these parts are not included, but are required to assemble and use:
