Electrical Engineer for 19 yrs. I do power designs, microcontroller designs as well as Arduino designs. I engage in personal projects for things I can't buy. My prior life was an electronics technician. I am also a home machinist. I also collect HP and Tektronix test equipment that I restore. I also have an account with the LTSpice users group @ Yahoo.
