I'm in the process of building this based on your instructables. First, I just wanted to say thank you for putting this together with the amount of detail that you did.
I have a question though. If I built this with an interchangeable power cord so that I could plug it into a 240V outlet or a 120V outlet would I have to change any of the internals or any of the PID settings for it to function? I realize that it will have half the power, I'm just hoping that I can use the same controller with multiple input voltages.
Thanks for the help,
