I am an electronics hobbyist. I have 5 years hobbyist experience in Arduino, and another 5 years in Raspberry Pi.
I have a rusty diploma in electronics engineering from Hong Kong Technical College. After graduation, I worked in the local electronics industry as a technician, but not for that many years, because all the electronics manufacturing plants in my city moved up to mainland China.
So I left my electronics engineering career for good, though I still enjoy playing electronics as a hobby.
