== Idea ==
We have a shelf with 3D print and other demo projects. It got a bit messy over the time and it would be nice to make it cleaner and more beautiful so we can impress our visitors ;-)

Adrian and Chris started already to add the old touch PC to the shelf to control our  home assistant devices. 

Plan is to add some control-able LED lights and control for other stuff in the shelf (3D Print marble run, digital cube etc.). 

* two parts for 3D prints with LED lights
* one part "Terrarium" for small animals build out of electronical parts
* one part for blinky LED circuits
* drawer: one part of moving stuff
* 3 x drawer for sticker and co. 

=== Details ===
Multiple ESP Home + WLED + Relais for controlling on/off stuff + WS2811 stripes powered by 5V power supply. 

The solution should be able to be controlled by Home Assistant, but will have also a manual mode (like switches for enabling/disabling the moving topics) etc.  

More to come...
