From blue to green

The controller charging station like it very much and me
also looks good.
There may be one or two controllers are loaded.
At the bottom of the station is a 360 ° light ring
mounted.
Depending on the charge status of the ring either blue glows (Loads) Green (loaded)
Unfortunately, there is no on / off switch, so constantly has the plug
be drawn

Cool: whichever Cotroller loaded Leudet the ring only in the respective 180 ° field of geadenen Controller's
