Bellevue WA, USA, A tiny blue/green planet known as Earth.
I am a software engineer with 30 years of professional experience developing software and about 10 years before that as a hobby. I have created schematics, board layouts and prototypes for non-contact profilometers, aero/hydroponic monitoring/control systems and random experiments on my test bench. I love designing/building complex sensor/data collection/control systems.
I used to be very active on DevShed, but I abandoned that site years ago.
