Happened again, close to 3m periodicty. worker2 in experiment "Temperature Test 3" Attached is the OD data. stirring and ir led reference looked fine during that time, too.

Occurred again in worker2. - restarted stirring twice. No effect. - tried reducing the IR intensity (maybe the opamp was saturated) - no effect. - relative IR seemed stable (and...
Current theory is that is caused by CO2 bubbles. - noise occurs after a period of a hours => critical amount of CO2 produced to form into bubbles. Also seemed...
Solutions: - allow for more oxygen transfer - slower stirring RPM to not trap small bubbles in middle
variance seems to rise near the peak of growth and immediately after Below is log-scale of rolling OD-mean vs OD-variance Scatter plot of the relationship is pretty strong, which suggests...
Another one:
ORRR a local persistant cache of this data...
this sounds like it is related to #252
