Anand Agarwal's edx course on electronics made me finally get some understanding of the topic after years of struggling over Horrowitz/Hill and the like. Was also free back in the day.
I self-studied his book "Foundations of Analog and Digital Circuits" a few years ago and really enjoyed it. Very accessible.
I also tried to self-study Art of Electronics first but it's not really friendly to beginners. Been revisiting it though recently, in the context of the accompanying lab course.
That's a damn good book and course, from what I've read and taken of it. I'd like to go back and complete it to refresh some knowledge and learn a lot of new things.
