Paul's reader idea sounds fine. I have a super simple idea, how about a 3D-printed
guide with a geared hand crank and a bracket for attaching a mobile phone looking down at
the
tape running through the guide below it. Then set it to record video and crank away at a
steady rate. The crank has a meter or moving widget to add additional means of tracking.
At a later stage some video processing could read the pattern from the video. There would
undoubtedly be a python library for that. It would capture the label and other
labelling nicely too.
That could certainly be done. Not that 9 photocells is all that hard, though. I'm
not sure if the Python code for this exists but it can't be all that hard to write.
I think I saw something similar for a card reader: feed the card, position it under a
camera, take a photo, repeat.
