No, no entropy change between us, we are pretty much of the same
understanding I imagine. - but you may or may not be altering
SolarWind's :-).
I noted that you said "thermos" BUT that he said "EVEN an airtight
lunchbox should do ..."

So I addressed where he had got to and was going.

You are of course correct about the thermos technically being a
technically superior solution.It also has limitations which may or may
not outweigh the gains compared to other alternatives.

As I and others had noted, if you place the board in a sealed sub
container you can then (probably) more easily control the RH of this
smaller container. Both heating the container and/or  dehumidifying it
with eg a Peltier cooler were suggested as alternatives.
