This video seems a bit lacking in information. Very cool to see the actual innards of the diode, but it feels like a quick picture and 2 sentence description could cover the same amount of information.

But then how would you be served 3-10 ads?

Not sure I agree. The extra time and listening to him gave me some ideas on how the parts are used, and made. He talked about the materials and explained it in different ways. It's awesome to see what people are interested in.

This video also includes a look at cross-sections of resistors, inductors, capacitors, and standard diodes too!

I’m surprised he still has fingerprints after all that sanding - impressive!

Really neat, thanks for posting. Good example of cracking open the literal black box of these various electronics components to see what's inside

a transparent belt-sander would be handy

I also noticed he doesn't use gloves :)

Fun video, but one note: You should always use sandpaper as if someone else is paying for it. It gums up faster than you think, and if your "250 grit" sandpaper is full of tiny particles that wore off and is now acting more like 1000 grit, it just means more wasted hours for you. It's fairly cheap stuff, so don't forget to change it often - certainly more often than seen in this video.

This is particularly important at the initial state where you're eroding down to a level - when you're just going through grits smoothing it matters somewhat less.
