I am trying to design an auto pilot for flying four line kites and I need a way to spool and unspool measured amounts of line/cord. I was thinking of passing the lines through an aluminum block about 75mm long that has 4 holes drilled in it--one for each of the 4 lines--with some sort of optical sensor aimed at each of the 4 lines. The lines would have marks every 25mm.
I am having trouble finding the optical sensor. I looked at the gesture sensor and it is nice that it can detect the direction of motion but it looks like its "read" time is pretty slow--likely too slow for 1mm wide marks zipping by at 25mm increments.
Any suggestions for a higher speed sensor for counting in either direction? (Line being reeled in or fed out).
Thank you in advance for any help.
