I've worn many hats. Electronics tech in USMC. Electronic security and fire detection. CCTV tech. Blacksmith. Electronic access and traffic control systems. Now I'm not worth a plug nickle trying to dodge kidney stones. Old enough to know the difference between 'gee' and 'haw'. Tried to get the nieces and nephews into arduino and r pi, which only led to me getting a new hobby. Oh, almost forgot, I do some weaving and woodwork when possible, too.
