Fibonacci64 Goggle Lens: 50mm disc w/ 64 RGB LEDs
Sold by Evil Genius Labs
$32.00
No tax for United States [change]
The 50mm diameter is perfect for mounting in the lenses of costume goggles!
Please note that for the goggle build you will need to ORDER TWO 50mm Fibonacci64 Lenses! The goggles are NOT INCLUDED, but available from Adafruit here: https://learn.adafruit.com/kaleidoscope-eyes-neopixel-led-goggles-trinket-gemma
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. 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.
The four mounting holes are surrounded by capacitive touch compatible pads. They're connected to the A0-A3 pads/pins on the QT Py footprint. The SAMD21 QT Py supports capacitive touch on these pins.
