I've got two questions.
A) can you recommend a quality power adapter? I'm thinking maybe just buy a laptop style this time around.
B) Currently when you change your I value in the PID it drops that sum to zero and you have to rebuild the value. How difficult would it be to prevent that? In the past I would manually change the B value every so often so that the cook wouldnt have to go through a cycle to see where your new settings land. I think if this could be done it would making tuning your pit a little easier. Thoughts?
If you mean a switching power supply when you say "laptop style", I had lots of weird problems when using one of those. I have seen comments by others saying the same thing.
