I have successfully moved my project to the garage!  And it works. 

I wrote software for the Raspberry Pi to log temperatures and status from the teensy uC.  I have uploaded my current revisions of Teensy and the Python code I am using the Raspberry Pi.  The teensy is currently set up on an with a hard interrupt every 60 seconds and transmits temperatures, output of the scale at the bottom of the freezer and general status to the RPi for logging.  The teensy is currently programmed to turn on the freezer for five minutes out of every 20 minutes.  This is a 25% PWM cycle and is working like a charm.

I placed a carboy filled with water in the freezer and I am using the temperatures recorded to model the system.  In my next update I will add details on the mathematical model of the system and the values I have calculated.
