Dear Warren and Mark,
I have hacked together a very simple setup with the transistor circuit
and the opened Thunderbolt case (not its own case, but the front lid of
my outer case opened). The CPU fan was placed about 2" away, only
blowing indirectly into the case..
The results are simply ama
Dear Mark, Warren, Arnold,Bob and Charles,
Thank you all for the interesting responses. I am most interested about
the implemented temperature control in Lady Heather:
I see that there is a setpoint to be entered via 't'+'t', but I am
uncertain about the function of it. From the heather.cpp i
Hi
I see a degree or more over the weekend sitting on the bench. With some effort
that can be brought down to a half degree or so.
The real question is weather you see the "signature" of the temperature showing
up in the EFC plot. To be precise do you see the signature of the lab
temperature,
Using Lady Heather's temperature controller (fan+cardboard box+solid state
relay+baffling and thermal mass to taste) I get around +/- 3 millidegree
temperature control when the AC/furnace is not running and +/- 20 millidegrees
with them cycling. Long term temperature average is down in the te

I am just wondering, if I should rather worry more about high

slow variation can be compensated by the control loop while for
quick changes, the loop is just too slow :)
This has been discussed quite a bit on the
Hi Achim,
I have very stable thermal conditions in my house. The temperature
indicated by the box (internal sensor) does stay stable within 50 mK/d
when the sun is not shining with very slow ripple. On sunny days the
in-box temperature does climb up by about 350 to 450 mK (less then 100
mK/h) and
Hi list,
as my Thunderbolt is now nicely cooking for a few weeks now, I am
wondering what a typically achievable ambient temperature
stability/variation is in your setups.
Of course, a more stable environment is better, but currently I am
struggling to achieve more than +-0.5 K variation on t
