Description

Aureole is a programmable LED disc consisting of 24 arms each made up of 21 RGB LEDs. Powered by an Arduino ESP8266 and Canvas Cast. Animations can be streamed over Wifi/USB or programmed directed on the Arduino.

Details

An unusual shaped display is great for creating different types of animations, patterns and designs. Here are just a few, make sure to check my Instagram (Motus Art) where I post more animations regularly.

I build this display with a graphic equalizer in mind. The 24 arms of LEDs to display 24 bands of frequency ranges with falloff, changing colours, patterns, whatever you can think of to bring music to life.
The audio processing (FFT) is done on the computer playing the music in JavaScript using the WebAudio API, animated and sent to Aureole.

A realtime visual feed of Cryptocurrency trading. Green=buy, Red=sell. The length and speed of each trade indicates its size & priority. Kraken provides the realtime trading data WebSockets, JavaScript listens for trades and then animates them to Aureole. The white spinner indicates the feed connection is open and brings some life.
