I found a nice low-cost enclosure that's the size of a very small bar of soap, but the 3 x AAA batteries take up 80% of the space!

(It looks better than the photo, especially in black).

I had to make a paper PCB model just to double-check, since everything is so tight.

The prefect temperature probe for a summer bbq! Great work. You could consider using a lower output voltage LDO, say 2.85V. As you aren't sampling your thermistors ratiometrically, and assume 3.3V is constant. When the LDO goes into dropout your thermistor readings will be slightly off.

I find this project very interesting. Could you please put some reference to that device you call calibrator? I would like to take a look at the manuals to learn more about its uses?

That is working quite nicely. It is rewarding to take a low cost approach and still get great results. Well done!
