im going to agree with both dongulus and bored at work.
i liked the power supply design videos. the way he lays everything out, tells why he chose what he did, then throws it all out the damn window and starts over, lol. i like things where they talk about design. WHY things are put where they are. i know (some) theory. theory can be learned anywhere. why/how things are done in the real world, especially by someone whos btdt and knows his shit, i find interesting.
otoh, everyone has different learning styles. i like daves videos, there are tons of ppl with electronics videos out there, some, i just cannot watch. different ppl will explain things in different ways, just the same as different ppl understand things in different ways. you need to find someone who explains things in a similar way to how you understand things or the videos (or books, or lectures, ect..) are not going to be as effective at best, or completely useless at worst for you.
