I'm not offended, Tony. I'm paying for the $35 of instructions 'cause I don't have the electrical knowledge you do or the time to become an expert. My Dad had a 1st class radio license and he designed a $300 transformer/computer mainframe interface that Westinghouse was charging the power company he worked for $5000. I mentally kick myself in the butt everytime I think about times he wanted to impart this kind of knowledge to me when I was a youngster and I always had something "better" to do. I'm paying for it now.
