Hi,
just discovered some fabulous free electronics courses from MIT in the US.
https://www.edx.org/course?search_query=electronicsRun as part of the EDX project. these are the same courses that MIT runs for its undergraduate programs. Free if you don't want a certificate at the end... $99 if you do....
Perfect for a beginner like me, I understand at least the early stuff.
cheers
Gary
