What do you want to make? Its making your own board from prefabricated components and chips thats relatively simple. You simply buy the components and solder them together and there are even services that will assemble them for you if you give them the plans. If you want to make the components like the integrated circuits themselves at anything close to a modern level thats much more expensive and difficult and I only know of a few people doing it by themselves like this guy. https://www.youtube.com/watch?v=IS5ycm7VfXg
I am not making anything.
I was just wanting to better understand the process.
Wow I want that guy in my Tribe when society completes its breakdown.
