A little hack
Ever since I had my observatory built, I always was worried to misplace or even lose the remote control of my Baader-Planetarium dome. So now it was time for another little hack. I created a 3D design of an adjustable wall-mounted holder for the IR remote control and uploaded it to Thingiverse.
I printed it and attached it to the wall in my observatory. Now I always know where to find my remote and with the cables attached to it I can even send key-strokes using an attached Raspberry Pi. Of course, this Raspberry can receive MQTT commands which makes the connection between my smart home and my observatory dome.
