I'm curious as to how non-space rated parts will do in unpressurized altitudes (partial vacuum) like that. I would think any entrapped gas would want to expand and perhaps blow device apart.
Noted! Also bookmarked the 1-Wire discussion since we're using Maxim DS18B20's for interior and exterior temperature sensors. They only go down to -55°C so the exterior sensor will probably bottom out on the way up (should be about -70°C between 11 and 20 km altitude) but then it should warm up again in the stratosphere.
