Built my first computer circa 1978 by hand-wiring a 6502, ROM, RAM, some buttons, and some LEDs. EEPROM programming used a motorcycle battery controlled by a 555 in one-shot mode and tiny DIP switches to specify address and data values. Used this computer to automate a credit card cutting machine at the company I worked for. Been hooked ever since, and even got to share my interests with others for a while when I taught night classes at the University of Washington.

Current interests include (but are not even remotely limited to):

• ARM-based embedded applications (from bare-metal Cortex-M to Linux-powered Cortex-A)
• Renewable and Smart Energy, such as the SunSpec Common Smart Inverter Protocol (CSIP) (I'm a member of several SunSpec working groups), solar power, LED lighting, etc.
• Combating the divisiveness currently engulfing the world by being as helpful as possible and encouraging others to do the same
• Helping rescue animals and pushing for no-kill animal shelters
• Studying and applying Agile and Lean management techniques
• Creating interesting Android apps (though still in early stages with this one)
• Writing of all kinds from technical to fiction
• Chess, especially striving to not let kids embarrass me in tournaments (limited success here)
• Vintage computing (yes, I still have 6502s in my house)
• Networking (the computer kind, though I also like the human variant)
