Like the stirring PID isn't stabilizing to its target value.

I had a bunch of jobs running for an experiment, but then I accidentally connected the 5V pin to the GND pin, which killed the Pi. Upon reboot, all the...

So this is interesting. I was seeing some very wonky temperature inferences in one of the pioreactors: very noisy, very unstable: Even the inference coefficients looks unusual: p=-0.008, q=-0.101, when...

When I rotate the vial, the OD signal can vary ~2%. This is a potential problem in #199. Why is there _any_ variation when rotating the vial? - changes in...

Probably the od_blank number is the most important number in the entire protocol. How can we improve it? - [ ] have users innoculate with "enough" sample s.t. the blank...

turbidity / OD signal / optics

Our Kalman Filter is non stationary, and so we should feel okay scaling our matrices as the experiment progresses. One important parameter is the observation noise covariance. For example, at...

Ex: I had a comment beside the KF parameters, ``` [growth_rate_kalman] acc_std=0.2 obs_std=3.0 # ↑ smooths growth rate od_std=0.001 rate_std=2.5 # ↑ more responsive growth rate ``` but this isn't...

If the OD signal looks like this, then likely the LED driver output is saturated and we are basically seeing the 5V rail noise. You can test this by running...
