Jim Weir

Jim has been teaching in the CA Community College system since 1971, first at Miramar College in the Aircraft Inspection and Maintenance dept., and since 1981 in the Electronics and Mechatronics program at Sierra College. He is currently the Vice President and Membership Chair for the Sierra College Faculty Association.  

He attended Grossmont Community College and graduated from San Diego State University in 1967 with a degree in Physics, Mathematics and Aerospace Studies. When not teaching, he finds time to run his aviation electronics manufacturing company, write a monthly column for a national aviation magazine, teach student pilots, inspect aircraft for airworthiness, keep the orchard trimmed, plant the garden, and take the airplane up for the occasional pleasure flight.

Prior to his academic career, he worked on the space program (Apollo, Surveyor, and Viking) and put himself through school as a mechanic for Pacific Southwest Airlines (PSA).  

Jim lives in Grass Valley on a couple of acres of garden and orchard with Gail (also a flight instructor and consummate web guru),  Katie (the Sheltie), Ollie (the Lhasa Apso), and Charly and Gnarly (the pound brother kitties and world-class ratters).

Mike Robinson

A self-described full-time electronics hobbyist, part-time teacher and some-time professional technician, Mike Robinson was born and raised in Northern California. With qualifications largely based on experience, he's been a part-time instructor at Sierra College since 1985.

Mike's interest in electronics blossomed when he enrolled at Sierra College to learn to troubleshoot the devices he was busy building. The hobby became a vocation. He has worked for a diverse group of electronics-industry employers in positions that include assembly, board test, final system test, engineering aide, PCB designer, design draftsperson and project engineer.


Mike has more than three decades of real-life technical experience, almost a quarter century of teaching experience, follows a practice of only teaching classes to which that prior real-life experience applies, knows what it's like to work a full-time job and go to night school and tries to express the excitement of teaching his hobby.
