Not really sure, because my bubbles prevent me from understanding how many other people are interested in certain things outside them. I guess the closest thing I could thing of is my interest / work in certain subsets of retro computing that I don’t typically see from other hobbyists. I play around with retro telecom and networking stuff and designed (but haven’t yet built sadly) a user mode X.25 stack (along with a kernel version on Windows) and am working on a plan for some ISDN stuff for a custom “PBX” to bridge some old H.320 phones with modern WebRTC stuff. If I ever finish those, there’s a few other “retro” stuff I’d like to look into. I also play with more modern stuff, mostly imagining implementing an 802.11 controller (hopefully a 802.11bb one when released) and a custom DOCSIS modem. Part of my problem with a lot of this stuff (and why I imagine I don’t see a lot of people doing it) is 1. I generally need a lot of expensive equipment to be able to designed labs for this stuff that I can’t always immediately (or ever) afford and 2. It requires knowledge from several separate and often complex fields. Also it’s a lot of work and time to invest in a niche interest solely out of curiosity.
