I loved the Opamps video. Can you please make one covering PLL (phase lock loop), VCO & stuff?
As mentioned above, have you checked out the w2aew youtube channel?
If found it really good, well organized and explained electronics basics.
Now, this is purely my opinion; Dave's bragging and conversational style is very entertaining
and can be informational/informative as well, but for education w2aew just works better ...
