Hugh: thanks for the suggestions. Probably a mechanical alignment problem. Didn't think to just run one channel and use the encoder as a counter (though I had the encoder set up in SW as 1x), will detail student to run experiment tonight. Don't have a 100 count new encoder wheel around; not even sure if they make one small enough to go on the backshaft of a BaneBots...
is OPB625 reflective? looks transmissive to me. Was considering Optek 720s...
I'm seeing if we can find the parts to do a homebuilt Hall Effect on perf board tonight; just want to cobble something together so that programmers can get their feedback loop working, then take the time to determine what's reliable and swap it out closer to bag day. Will post what we do for interim, and what we end up with.
Programming is easy. Sensors are hard
