Suppose the satellite is a geo-stationary at 40± thousand kilometers
orbit (is that right?), and that during 2 hours (in every 24) it will be
into the earth's shadow, chilling somehow, and suddenly it heats like
hell again during another 22 hours, not counting some occasional shading
from the moon. Ok, there are reflective foil radiators and temperature
protectors, but it is *not* a nice 78¡F all the time.  Build a metal
box, protect it externally with everything you can think about
temperature reflectors and thermal isolation, install it inside a 600¡C
stove, how long it will need to reach 250¡C inside? PIC16F84A industrial
temp is -40¡C to +85¡C, what is the mil spec temp?  As support reading:
