Many thanks to @petewill for his work and inspiration.
I will post final pictures when ready.

@petewill I already build the wooden box, and i have all electronic parts. I do wait for threaded rod, threaded Insert, Ball Bearing to arrive from china. I just finish today the shield that will hold arduino, testing lcd screen (i have a different version then you have, less pin's and no need for resistors). I will try to convert your schetch latter to V2 (still need to make an gateway for V2). If successful i will post the code.
