About Us — Who is Tubelab?

Tubelab is operated by George and Sherri Anderson. We have been operating an electronics design consulting service (G and S programming) for the past 25 years. Our consulting firm started with the microcomputer industry in the mid 70’s designing SS-50 bus boards, and has evolved to embedded system design featuring the Microchip PIC processors and the Motorola HC11 series. I (George) have worked for a large electronics company designing cellular phones and communications equipment for the past 30+ years. Before that, I ran the service department at a large stereo store. I have a bachelors degree in computer engineering and a masters degree in electrical engineering. I currently hold 3 US patents in the communications electronics field. Sherri also worked at the large electronics firm for several years in the test equipment lab. She stopped working full time while we had children at home.
