## Description

<iframe width="560" height="315" src="https://www.youtube.com/embed/RU-QcP_9QEI?si=eJNQzuFhY1w3gvNQ" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe>

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 WS2812C-2020 each only consume a maximum of 5mA, and that's at 100% brightness, solid white color.  That's only 320 mA for all 64 combined. They are still very bright, and I usually only run them at about 25% brightness.

It has solder pads on the back that match the pinout of the [QT Py by Adafruit](https://www.adafruit.com/?q=qt+py), or [XIAO by Seeed](https://www.seeedstudio.com/catalogsearch/result/?q=xiao). 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.

The six mounting holes are surrounded by capacitive touch compatible pads. They're connected to the A0-A3, A6 & A7 pads/pins on the QT Py footprint. The SAMD21 QT Py supports capacitive touch on these pins.

** Case Options **

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.

**Specifications**

- Size: 5.83 x 5.65 x .063 inch (148mm x 143.5mm x 1.6 mm)
- 2 layer printed circuit board
- FR4 substrate
- Black SMOBC (solder mask over bare copper)
- HASL (Hot Air Solder Leveling)
- Designed and assembled in the US by Evil Genius Labs

**Parts**

Options available to purchase for additional amount:

- Diffuser: 3mm black LED acrylic flower.
- Open Case Kit: diffuser, back plate with wall mounting hole, M2 black nylon standoffs, M2 black metal screws.
- Fully Assembled: diffuser, open case, and assembled [QT Py by Adafruit](https://www.adafruit.com/product/4600) controller.

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:

- Microcontroller (Arduino, ESP8266, ESP32, etc)
- Wires, connectors, crimp tool, etc.
- Soldering iron, solder, etc.

Parts I used in my builds:

- [QT Py by Adafruit](https://www.adafruit.com/product/4600)(https://electromage.com)
- [Chemcast Black LED Acrylic](https://www.tapplastics.com/product/plastics/cut_to_size_plastic/black_led_sheet/668)
