Maybe you should aim for something more precise, such as forums about microchips, or keyboards, or soundsystems (there has to be great ressources about those, I have friends who build their own to throw big raves), etc.. I started getting into microbiology and chemistry as I started brewing beer (I'm just here because my roommate is a webdev and I'm interested in entrepreneurship, I can't remember how to code a loop in python and couldn't tell you the difference between AC and DC), and there's nothing great specifically about those sciences. However there are great forums (facebook groups and subreddits in particular, with a good mod team they can be great platforms) for brewing (both professional and home-scale), growing mushrooms, theory behind drug synthesis/purification, and probably a lot more stuff I barely know about.
