Mc Lighting (the multi-client lighting gadget) is a very cheap internet-controllable lighting solution based on the famous ESP8266 microcontroller and WS2811/2812 led strips. It features a self-hosted responsive web-interface, a REST-API and a websocket connector.

Because of it's open architecture and APIs it's easy to build new clients for different platforms (iOS, Android, Windows Universal Apps, Siri/Cortana integration, ...).

## The Hardware

The project ist based on the famous ESP8266 microcontroller and WD2811/WS2812 LED strips. There are many variations of the ESP chip out there, but I chose the NodeMCU dev board, because it's powered by micro USB and has a voltage converter included to power the ESP which uses 3.3V.
A standalone ESP8266 or a Adafruit Huzzah should work too.

The RGB LED strips are also available in many different flavours as strip or as standalone LEDs and can easily be chained.
