FDM 3d printing is still a wild-west and there are plenty of avenues to explore. Not sure what else to say about that other than as someone with daily and close personal proximity to the 'industry' that cropped up I am well aware that there is plenty of work to be done by enthusiasts and niche-people.

Engineering and machinery is still a place full of exploration if you have the chops. If you don't have them yet then there is plenty of topics within that domain to explore; you'll never run out of things to learn there.

My 0.02c : learn to disregard the crowds and focus on your own work. Just because people are doing something you used to do doesn't mean they have anywhere near the depth of understanding and 'freedom of movement' as you do as a 'resident expert'.

also : the fact that no one is doing something may be a signal; crowds form for a reason. Very few hobbyist bomb-squad folk and rabid-racoon-caregivers, get what I mean?

the GPT3 models didn't keep you from learning about ML. The industry didn't push you from keyboard and printers. You did these things.

If you're trying to lead an entirely one-off human life with total uniqueness from other people then all I could suggest is hallucinogens , but personally I think that the goal of just being unique for the sake of being unique is ludicrous.

Just find enjoyment, that's the goal for me at least.

There's a lot of legacy / retro coding out there that despite the output being used by anywhere from hundreds, to thousands to even millions of end-users, it still involves small tight night communities per project, sometimes they overlap somewhat. I've mentioned it before, if you follow people reverse engineering Shockwave, you will note that they are all on the same communities to capture as much wisdom from others as possible. In niche reverse engineering communities, the smallest thing can be a life changer.

My hobby is organizing in-person meetups for random people to get together, chat and make friends. Barely structured, if at all. I've found this rewarding and ended up making friends this way. You have to accept that 5-15% of the people who would show up to something like this are genuine weirdos you probably don't want to be around. And another 10% at any given meetup are autistic or neuro-divergent but well-meaning…

Between the genuine weirdos, the autistic and/or the neuro-divergent, is there anyone left, really? Do the "normies" genuinely exist? Happy-go-lucky, knows a bit about everything but doesn't nerd out on anything, picks up every conversation subject and listens and holds their own in a manner that is just right? I am genuinely curious about the existence of these "superhumans".

Not sure if you were looking only for indoor hobbies, but I picked up Kiteboarding recently, and it is the most outrageously fun thing I've ever done.

It's like being a kid and jumping off the house with a bedsheet, except it works. Most mistakes are laughed off by splashing in the water. I'm 3 years in and I can jump 7-10m then fly like a bird for 5-10 seconds without consequences.

Even as a beginner, sailing around or just feeling a kite pull you around is such a blast. Keep in mind it's really difficult and pretty much requires 10-20 hours of private lessons.

Not sure if it is niche, but focused on one South Asian music genre -- been working on this personal project to compile, and collect resources from reliable sources along with mapping lineages of people. Also, I archive a lot of music for this genre from different sources before it vanishes from internet!

https://www.qavvali.com/

EDIT: I have one more page but that is not in navigation yet for people not familiar with the genre. The site is still work in progress -- if you have any feedback, please do leave it here, on the website if you can. The content curation is the most tedious part! https://www.qavvali.com/tradition/

I am trying to build microphone capsules in my garage. Trying to go below 14dB (Primo EM272 level), under 1". It is difficult but rewarding. I do not expect any financial benefits from it, even if I make it under 10mm, because it is very time-consuming. Big players already have massive factories doing 10,000x of what I am doing.

This is the most niche tech-related hobby I have currently.

There are many many of these socially-skilled normies. But, by virtue of being socially skilled, most have already pretty much filled up their social capacity and don't tend to show up at the kind of venues dedicated to helping under-socialized people meet up.

I’m obsessed with powerlifting. Not only because big numbers get bigger but also the physical changes that occur with a healthy dose of lifting each week. It’s also easy to track lifting stats and there are tons of analysis tools out there if data analysis is something you enjoy. Also, I’m trying to learn guitar - right now following the Justinguitar.com lessons

+1 on this - powerlifting is great due to 1) Rapid, specific initial progress, 2) Highly structured programming (e.g., RPE based), 3) Focus on strength vs. aesthetics is a great way to be more holistic about health & performance, 4) Forcing function on all downstream decisions (diet, sleep, alcohol). Adding +15 lbs on your deadlift can become strong motivation to drive discipline, 5) Drives the importance of recovery/rest on long term progress

If you like music and technology - there's a massive world of possibilities out there (e.g., software based music production, tone.js, music programming with Strudel).

If you have more money - 1) DJing/mixing on vinyl + record digging, 2) Modular synthesis (your wallet will hate you your soul will love you)

I’m a paraglider pilot and powered paraglider recently. Totally recommended, you get to connect with nature in a meaningful way. Also people who practice this kind of sports are nice. From a tech perspective there are a lot of data generated on each flight you can create your own way to capture that data or use already existing apps.
