## Description

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.

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 more LEDs.

**Case**

The open case is built with 3mm black LED acrylic diffuser, black nylon M3 standoffs, black metal M3 screws, and acrylic back plate with wall mounting hole. Available as kit or fully-assembled.

**Specifications**

- Size: 3.39 x 3.39 x .063 inch (86 x 86 x 1.6 mm)
- 2 layer printed circuit board
- FR4 substrate
- Black SMOBC (solder mask over bare copper)
- HASL (Hot Air Solder Leveling) Finish
- Designed in the USA

**Parts**

Options available to purchase for additional amount:

- Diffuser: 3mm black LED acrylic 90mm circle.
- Open Case Kit: diffuser, M3 black nylon standoffs, M3 black metal screws, and acrylic back plate with wall mounting hole.
- Fully Assembled: diffuser, open case, and assembled [Adafruit QT Py SAMD21 controller](https://www.adafruit.com/product/4600).

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):
  - Any of my [LED controllers](https://www.tindie.com/stores/jasoncoon/items/) will work.
  - [Pixelblaze](https://www.bhencke.com/pixelblaze) by [ElectroMage](https://electromage.com)
- Power supply, or run off of USB power from microcontroller.
- Wires, connectors, crimp tool, etc.
- Soldering iron, solder, etc.

Parts I use in my builds:

- [Adafruit QT Py SAMD21 controller](https://www.adafruit.com/product/4600).
- USB power from microcontroller, with [FastLED's power management](https://github.com/FastLED/FastLED/wiki/Power-notes#managing-power-in-fastled) to limit the maximum brightness and keep total current draw under 2A.
