I've done that with commercial-grade PICs. Frozen them to -20C and
dunked them in boiling water. Meh, it's a hobby. They stop working
but come back to life within the graded temperature range. That's with
simple timing test s/w running. You'd want to be careful with current
ratings and capabilities at the extremes and not have something super-
critical relying on the PIC or, in Rikard's case, the LM317
