This website is incredible if you are the type of person who LOVES knowing how things work. The link I posted is to his mechanical watch post, but go to his archive and look through his other content. Every topic is filled with a series of interactive elements that REALLY shows you how something works. I think his internal combustion engine post is awesome as well. If you like this kind of thing and want to support it, he has a patreon too.

This blog is incredible:

There aren’t many articles, but the ones that exist have been crafted with EXTREME attention to detail and DELIGHTFULLY interactive animations. I would recommend the mechanical watch and internal combustion engine posts specifically to start. If you like knowing how things work, this guys blog scratches that itch better than like, anything else I have found for the specific things he makes posts about. Have fun, be prepared to kill a few hours.
