You should post this in the mechanical engineering community. This is amazingly well done. We love this sort of stuff.

Thank you for sharing. I’ve studying everything included in these notes, I understand it all. And in the years that I did study this, not one of my excise books of notepads was nearly as detailed. I’d ‘look up the slides’ or ‘google it’..

These are beautiful and way more than just mildly interesting.

That is very impressive! I really like the detail view of the gauge indicator

This is so cool!

And it seems to ge written with a fountain pen. The times where people could write properly, beautifully, and made things to last.

I kind of regret being born in such a wasting consumption focused society...
