hello i dont know if here the true place to ask for help anyway ,
i made shading device that moves two ways firstly it folds to half which will be half void and other solid secondly the center of the shape move up and down with sun high angle i want to work it with dynamo and i do not know how , because i'm beginner
its looks as diamond-shaped   
so " rotating_angle " should move for 0 degree when its 6 am
to make the right half goes behind the left half .
and " rotating_angle2 " moves with x axis between 6-10 am
for example if its 7 am the angle will be 30 degree , and if its 8 am the angle will be 40 degree .
