Homebrew PCBs

YES...
there are temperature limits for all the components......
My interest here was in the shear fact that there did exist temperature 
measurement
circuits using diodes and transistors.....
and
for my real world application of 350 F  toner transfer I'll stick to 
rep-rap thermistors
which more than perform well enough for my purposes.

But the diode idea intrigued me.... simple enough... for other low temp 
applications.
