Tutorial on Schematics and PCB Layout?

[Prototype]

I don't know if you have covered this, I haven't seen it, but I was hoping you could do a tutorial on schematics and PCB layouts. Maybe walk through a printed copy of a schematic and go over the meaning of symbols and their importance, and how they all link together?

Some of this will be covered in the Power Supply Project I'm currently doing. I think Chris Gammell has a fair amount of this on his channel Contextual Electronics: https://www.youtube.com/user/contextualelectronic

I think that this is a common place.
