Thanks John. I am an Electrical Engineer by degree but have been in management for many years so I haven't done hands on EE design in some time. I worked in many capacities from DC controls design to Lithium Ion systems going back farther than I want to admit. Off subject but its odd how a person's career goes way off the reservation over time. I eventually got into ASRS systems (automatic storage and retrieval) and now I am in management and project management of global systems in the petrochemical industry . Life, career and single father got me off track on my KR2 and I am now at a point that allows me to refocus on it. So, I am relearning and learning all things KR. I am still balancing the father thing as well as career but at a better place. So, I have lots o dumb questions to ask.
