Nipkow disk can´t draw high resolution pictures because that need microscopic holes or house size disks mainly uses 50,100,200,400 horizontal res.

one trick still can give 2X more without extra holes using blue and red led   

i also testing quarter shutter what have every hole to disk 4 holes what is little smaller if disks are 1/2 then shutter uses 3/8 inches  every 4 holes are almost 

same line but first have perfect fits disk hole if first hole what fits and last what not very fit line error be X then first be 0% X fourth be 100% X second be 1/3% X third

be 2/3% X in  theory that be create 4X more horizontal pixels and shutter need to be faster to disk i think 125-150 but that is wild guess but that all be now only 

hypotheses
