Hello BigAl1 - I've been following your progress on the HVAC controller with great enthusiasm. A buddy of mine has a startup that massively speeds up the development of hardware devices through a software assisted design process. The company has a platform that automates the design, manufacture and assembly PCBs. He is mostly targeting IoT types of devices that makers of Rasberry Pi and Arduino people are doing. I mentioned your project to him and he is interested if his company can assist this and maybe future projects. His name is Tim Kay(
www.timkay.com). Would you be interested in talking with him.
Thanks,
