As Electronics for this Project I selected an Arduino Nano clone and a DS3231 RTC module. Quite handy to have box full of modules at hand.

I also reprinted the front grey frame part. I am much more satisfied with this now. The surface finish is better. I just changed the Filament - no extra rework. Here you can see the new frame with the test pole. The finale version of the pole will include a box for the electronics an the base.

Also need to finish the wiring of the LED which is only ~80% made in this picture
