Ok, try not to laugh at me...

We have several "real" environmental chambers here... but we have been known
to just take stuff outside and test it on the picnic table when all the
chambers are busy. We don't get much control over the temperature though.
Right now (in northeast Ohio) we can test outside at about 90F. If we wanted
warmer we could put the test article inside a car on a sunny day with the
windows up. If we wait about 7 months we'll have the 0F or colder. The hot
and cold is cheap (in fact it's free), you just have to wait for it to come
around. This is not usually practical for most people, although it has
worked out nicely for me a few times.
