...wanna try Central Florida???
I produced a device to analyze solar radiation, it needed to stay in the
open weather for a week for tests, in August, the ABS case melted, and
the battery pack wrap plastic just broke and shrink as if the temp
inside the case was around 150¡F (65¡C), when I took it back inside, it
needed to cool down for at least 10 min in the air conditioned to be
able to touch the batteries... can you imagine?  No one microchip got
damaged or any problems at all, even with commercial grade it worked
pretty nice, even the data stored at the e2prom was ok. Opening the
case, the smell was some like burned wire insulation. Atmel parts. I
guess I was purely lucky, huh?
