Acrylic cubes made from frosted acrylic illuminated by a single ws2812b led arranged on a string controlled by an ESP8266 with webservice to easily find it on the network.
Challenge: moodlight (any iot device) and smartphone app/web service - to find and control it.
Solution: custom rgb cubes lighted by ws2812b leds that look awesome and that can be easily controlled through a web interface provided by an ESP8266.
The solution Felix came up with one day - to find the cubes on our your network - is to simply code a web service that the lamp (ESP8266) connects to and sends its local IP.
You can then simply go to web service from your browser or phone and
it will redirect you to the lamps local IP.
For rgbcubes and software we use the Unlicense which essentially sets all code and other content into public domain because we have more important things to do than dealing with licensing - like hacking on other cool projects.
