After twelve days of data collection, the performance looks quite good.

Not unexpectedly, the ovenization yields different behaviour than both
rasPi models, which are very similar to the point that I needed about
two months of data to start using different control parameters for them.
The Tinkerboard is not very far off, but enough so I needed to
immediately account for it.  The main problem at the moment is that the
zero-TC temperature point is just beyond the first thermal threshold
hardwired into the kernel for the TinkerBoard, so I can't keep the
temperature high enough.  As TinkerBoard is still just in it's (standard
rasPi) case and not wrapped and boxed up which makes it more susceptible
to sudden changes in ambient and maybe also need higher temperatures
overall.  Not sure when I get around to try if wrapping things is
helpful or not, though.


Regards,
Achim.
