im wright about first version what i made Nipkow disk that are just testing version  to shutter idea with 4 holes made old CD and screen 1,5X1,5 inch 

screen area and motor. but if i build future real display like thing then screen get magnification and 90 degree rotation then i can use VGA signals to input 

i´think about shutter idea if that works maybe works also duple 

questions what i need to find answers by testing

are my shutter idea works ? how in details ?

motors speeds ?  led plink frequents ? how long is vertical lines in one frequents ?

are every hole or least half can use individual led i think like if made 256 holes disk can that use all holes 1 led  and how long vertical lines can that disk give ?

and can ardunino run that all 256 led calculation ? are there be possible  also 1024 pixel vertical line ? like you see i have lots of work to do in week.
