EE living and working in San Francisco. Areas of interest include sensors, circuit analysis, modeling and simulation, digital, embedded, motor control, power, solar. What else? Jim Williams was and is a big inspiration to me and I know own a bunch of vintage HP instrumentation, although the only one I regularly use is a Fluke Kelvin-Varley divider. I own 3 HP RPN calculators and use at least one of them daily.
