I am an electronics hobbyist. I have 5 years hobbyist experience in Arduino, and another 10 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 factories in my city moved North to Mainland China.
So I quitted my electronics engineering career for good, though I still enjoy playing electronics as a hobby.
