I do various things, but my current project is Project 54/74, where I'm trying to photograph, annotate, and turn into schematics the integrated circuit dies of every 54- and 74- series logic chip I can get my hands on. See the data at project5474.org. I don't monetize my videos, but I have a Patreon page where you can help me with supplies and equipment at https://www.patreon.com/user?u=3190442
