5:55 Notice the ferrite bead on the big beefy diode. (Which Dave actually pointed out later. Just scribbliong down thoughts as the video goes along.) Might have something to do with ringing from when the diode switches. A novel replacement for snubber caps?
23:55 I don't like the placement of that crystal. Seems like an IDC connector might apply pressure to it. Would be easy to move it a couple of mm in the other direction, methinks.
27:10 Not digging what your LED lights are doing for the videos, I must say. Maybe you can diffuse the LED strip somehow?
32:52 Sexy spring loaded knobs, eh? Ms EEVBlog: "How COULD you do that to me? What does that scope have that I don't?"
35:10 Does that flat flex split and go both to the LCD and secondary button board?
