OctaLight is a DIY project. It consists of an led strip wired in an octagon shape with a cross in the middle of it. It is powered by a NodeMCU chip with WiFi capabilities. Through implementation of a simple HTTP server, the light reacts to GET requests. It can be controlled via the in-built web control panel and has Google Smarthome support (see the library docs for details).
Required libraries:

| blacks=[int] | Number of black phases between flashes. | |||
| mode=[random | random_spectrum | order] |
The ordering mode of the colors. |

Pixel zero is situated at the controller and the outer pixels (red) range counterclockwise back to it. From there the inner pixels (green) form a bow. Not all the strips can be connected directly: There has to be a cable connection to connect the two inner strands (black-green).
