You need to zoom in sometimes. When you're editing (on a twenty something inch monitor) you perhaps don't appreciate how difficult it is to see what you're talking about. At 2:59 you're talking about the zener, very difficult to see on a tablet or phone. At 4:47 you finally think to look at the voltage rails with the 'scope. At last! Here we are at part six and some steps that should have been in part one are finally appearing. At 5:17 it would be nice to hear what the size of the ripple actually is. We need to hear the peak and ripple voltages e.g. "That's peaking at six point nine Volts with seven hundred milli Volts of ripple below that. The ripple is at one hundred and twenty Hertz." At 7:15 you should have been zoomed in by a factor of three, just at 7:58 your thumbs and forefingers inadvertently show what should be the full screen. 7:38, that's not dew (a weather phenomenon) that's condensation.
