This is a remix of the adafruit "On Air Sign for Twitch"

I wanted to print the original one, but my printer is to small... So I've decided to remix it. Just made it a bit smaller, merged the "on air" plate with the front, changed the screw mounts (I've used 6 M3 screws 20mm) and added a hole to the side for an external 5V power supply.

Inside works an Wemos D1 Mini with Wifi, I can set the color of the WS2812B leds by using MQTT protocol (which integrates perfectly in my smart home system).
