I'm looking for make a rotary encoder or an incremental encoder. I
bought a IR transmitter receiver from sparkfundotcom.
I was hoping to use it to detect black and white transitions on a black
and white vinyl decal. But it really didnt work. The problem is that
the lines are pretty small. They are about .070 wide/thick. .070"
black line, .070" white line, .070" black line, etc. I was thinking of
getting the the QRB1134 phototransistor detector kit but it has to be
at least .250 inches wide/thick.
It is found here.

I have to get something that can see smaller lines. The transition
lines (black to white) would be travelling pretty fast so resolution is
critical. Do you have any suggestions on something I can buy to see
these lines? I sure would appreciate any input that you might have.
Please be specific. If you don't want to post, please send me an email
at [email protected] so we can talk further.
Thanks alot,
Todd
