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
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.
