ART-net is awesome.


Raspberry Pi 3 + Touchscreen

Distro based on the QLC+ image (raspbian jessie)

QLC+ XServer less build that renders directly in GL buffers for performance

H801 based clients (ESP8266)

Arduino based firmware that implements ART-net

Temporary setup with QLC+

Connect to "metalights" WLAN


Set ARTnet universe to 3
