Just want to call attention to the small youtube channel "TheStuffMade".
A number of good videos that would be of interest to the advanced beginner/intermediate hobbyist.
For instance, there's a nice video on reducing the noise one of those cheap switching 30V10A power supplies that I haven't seen anyone else do.
The one's I've watched are very well done and contain a lot of good nuggets of EE practice.
