    I am working on Hypercube version of the R2 using an Arduino Board. It is pretty much complete and I just have to clean up the documentation on the Forum. I had to isolate the GND on the thermister and am using the two thermister hots on the downtown board to connect to my Arduino board. Using the common GND was not a good idea and it degrades the temp regulation. Partsbuilt.com is going to make a downtown board with a jumper on it to allow the isolation of the GND and use the two hots.

    It is the code I am using. No other code I tried worked on every function. The PID tuning was a problem until I used this code.
