Synthesizers! I like it because it's tactile and immediate, and you're not glued to a screen, but can create fun-sounding beats.

Nowadays there are nice, cheapish groove boxes that are perfect for noodling on the couch. I started with the Novation Circuit Tracks, and also really enjoy the Teenage Engineering EP-133. Not to say that I am any good at this, but it's an enjoyable hobby! Bonus if you are friends who are also into it and you can jam together :)

I was into woodworking, then I got into building fly fishing rods from bamboo.

Fly fishing has been around for a long time. They used to build rods by hand out of bamboo - a specific species of bamboo native to southern China - before factories started making them out of graphite, fiberglass, etc. for cheap.

Modern fly rods are a few hundred bucks. If you try to buy a bamboo rod in a store, they run $2K-$5K. They take a lot of time and meticulous work to build, and the result is a functional work of art.

Woodworking is a ton of fun, and challenging. Bamboo rod making is a niche within a niche, and there are not a whole lot of people who still do it ... mostly retired guys with a lot of time. It's a great tradition, and it's about as far away from computers and technology as I can get.

I didn't even know how to fly fish until I built my first bamboo rod.

Here's a great video showing the process: https://www.youtube.com/watch?v=lfTvRxcTuV0

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, kind and full of interesting insights and hobbies, although perhaps difficult to socialize with, at least until they get to know you're well-meaning too.

These challenges come with the territory. You end up talking to people you'd otherwise never meet in the normal course of your life, and it's neutral at worst and wonderful at best.

Traditional archery.

I started a few years back and have been doing it off and on since. It's challenging but a lot of fun.

I shoot a lot of older style "recurve" bows, but the main style I shoot are horsebows, that is, bows that were historically shot from horseback.

They're very lightweight and you can shoot much more rapidly than you can with a more modern/mechanical recurve or compound. Right now I shoot around 20-25 arrows a minute. Not amazing compared to experienced archers, but a lot of fun.

I have a number of bows, but here are my favorites:

Assyrian: https://www.bogararchery.sk/image/cache/catalog/product/boga... Buryat: (No longer available)

I also shoot an English longbow from time to time.

The horsebows use a technique called "thumb draw" which is very different from the way most bows are shot in the west.

Here's a great YouTube channel if you want to explore getting into it: https://www.youtube.com/@ArminHirmer

I started designing my own clothes. The insight was that I spend 80% money on suits that I wear 2 times a year, and the rest was low quality clothing I actually wore.

I flipped it, and made suits and pants that I could wear everyday.

The fast fashion stores were crap quality, my body is not a template size and I care about fabric and comfort.

The process was to learn how to sketch, to determine fabrics, colors and fit. I made pants that stay comfortable even after I eat food, I made suits that I can wear casually.

I don’t stitch myself, for that I worked with multiple workshops, until I found one that works for me.

Took me about 3 years to reach a point where all my wardrobe is designed by and for me.

There were multiple side effects on my confidence, my life, and the opportunities coming my way.

Despite AI starting to crowd this space, I've been spending all of my free time learning music production (doing it the old fashion way without AI). It's a great mix of technical and creative problem solving. Mostly focusing on dark ambient/cinematic composition, playing around hardware synths (Prophet 6, Subsequent 37, modular / eurorack, Digitone II).

If any one is curious, I put out a single recently (remaster from last year): https://soundcloud.com/vectordust/ion-dunes-1

My main personal goal right now is to release a full length album this year.

Railway preservation (full size, not model). It looks crowded when a steam train is running and the moths gather around. The reality, when the trains are not running, is typically quite different, with a small dedicated group. If a place looks too crowded, pick a smaller museum.

Think of all the jobs that have to be done to run a railway and you will be able to find a museum that does it: heavy maintenance, boiler work, fitting and turning, blacksmithing, woodwork, upholstering, painting, catering, engine driving, fireman, signalling, customer service, ...

It's a great way to meet people, learn new skills and work with physical things.

Animal tracking. I picked it up in college and it has been a real source of joy and a true challenge. It's also something you can do almost anywhere: urban, suburban, rural, out in "the wild."

A lot of people think of it as looking for paw/hoof marks in the mud, but tracking can actually be quite involved, requiring you to understand the environment and ecology as a whole.

For example, tracking birds is outrageously difficult and when I first started out I didn't think it was possible. But the more I learned about birds, their habits (per species), their environment, I started to see signs everywhere. It really got my eyes open and I started seeing the same old places in completely new ways!

And in terms of contributing something, there are all sorts of apps/organization that can help you identify different species and in turn you give them data in the form of pictures, location, etc. I use iNaturalist myself, but there are others.

I'm into innovation in HCI as a hobby, but it does get expensive so I would like to bring in some additional financial support for my unusual builds.

I didn't really plan to build HCI as a hobby, but I have a strong interest in hardware engineering and eventually I wanted to switch back to building things that anyone can physically see.

Years ago I built a hemisphere keyboard and now I've built an LED globe with a viewing portal. I started building visible things again because I had a vision and it's very satisfying to use the result. I spend more time using it now than I did originally building it, although it is definitely a work in progress. I want to build it again for a 2.0 version.

Design whistle sequences to get dolphins to respond in ways that will help you figure out their meaning. A few multi-million $ projects could use that, such as Google, Baidu, and SDRP.

Someone needs to solve barbecue. The entire industry is based on feel and experience. Why can't a beginner replicate Franklin's brisket by following a recipe online?

It's probably because the main measuring instrument (a probe thermometer) doesn't provide any feedback about fat rendering, moisture, etc. Plus, every brisket cut has different fat ratios and thickness, which means a recipe can't guarantee identical inputs like bread baking. I'd love for someone to throw some over the top engineering & experimentation at this.

If chess is a solved problem, think about skating to where the puck is going to be, an interest area a bit further away from relatively easier verifiability such as coding, math, and hard sciences.

Do you have any interest in digital humanities? Knowledge work where verification is still important but not as black-and-white as does the math check out, does the code run.

Do you have any interest in family history or genealogy?

My strange hobby was going on what I called "leak walks".

I lived in a town where on any sunny day I could go for a walk and be almost guaranteed to spot a water mains leak I hadn't seen before, which I'd then report and see how long it would be before it was fixed.

The record was over a year for one of them.

( Yes, it was a Thames Water area. )

Hang gliding. It's good if you are in an area with some hills and consistent winds. There are maybe a dozen well-established launch sites around the U.S. Sadly, I broke down my glider around 2001 -- and did a post-mortem on it to discover it had a minor dent in it.

Recommendation -- don't stall the glider at heights between 10 and 25 feet from the ground. Also, avoid barbed wire fences.

Nowadays, apart from stockpicking as a value investor, I use LLMs to develop AIs that don’t use backpropagation and that support continuous learning.

There's a surprisingly high number of people in my extended social circle who picked up archery as a sport.

It's actually a complex discipline with a huge range of bows and projectiles to choose from, each having unique characteristics you have to train for.

Training using VR equipment is picking up steam, as typically you need a sizeable amount of real estate to practice when the weather is bad.

Bellringing, specifically change ringing. It’s a type of church bell ringing that is rather algorithmic in nature. Tends to attract mathy types. Religion not required or expected!

If you have English-style tower bells near you, it's worth checking out, even if only to listen.

I view hobbies as something that I derive value or pleasure from. I do not approach them from the perspective of “meaningfully contributing”. IMO, that sounds more like compensation for career dissatisfaction. I’m not being critical. I just recommend choosing hobbies that you derive value and meaning from, regardless of what the world may think of it. For example, a friend of mine, with high pressure tech management job, quilts in the evening. He says it helps him relax. Doesn’t matter if anyone likes what he does or wants to buy it. As for myself, now that I’m retired I delve into a number of areas, just for me, and absolutely have no interest in sharing them or being recognized for what I do. Good luck on your quest.

Hydrophonic farming at home. You can play with sensors (acidity, humidity etc), LED lighting (frequencies, intensity, etc), vision processing (maybe throw in some AI buzzword here) to keep track of your plants and do some decision making.

Bonus: You get to eat the stuff you grow :)

You might look into applying RL in the domain of low cost robotics and drones. That would draw on some of your past experience but applied to a domain (robotics) which I perceive is seeing renewed interest.

I used to play Pokémon cards competitively. It was fun going to local tournaments and flying with friends for Regional tournaments. I stopped to focus on night school, and I want to pick it back up with the card legality change happening Friday.

Pokémon Champions just came out, so I might give up cards for the video game. We'll see.

> that isn't absolutely crowded

I'm sure there are field that should be absolutely crowded but where you can do something meaningful.

If I had free time, I would write an app to learn foreign languages I'm interested in. I'm pretty sure that there are good apps, but I tried a few ones, and none really fit my needs.

There are also software that I use a lot, like transcribe! which works well, but that I could see how to improve.

So as others mentioned, do something that you would be interested in.

After binging on youtube, I am working on learning to do leatherwork, small stuff at first like making your own wallet etc.

I decided to run for congressional representative.

You mention chess, Chessboxing is an interesting niche hobby where you play both chess and boxing.

I play chess but not chessboxing but hey, you asked for some interesting niche hobbies!

It seems that what you do is mostly related to computers within the niche hobbies but what if you can do something else too?

> Right now I'm making a chess engine, but that's already a solved problem

Not everything should be done for the end-result, sometimes its the process which matters, there was a great hackernews post about it (https://ergosphere.blog/posts/the-machines-are-fine/)

If you want something niche, perhaps make some portal-2 mods or make more efficient versions of using GlaDOS TTS within browser etc. (this is just something that I want to be honest, but I feel like it can be a niche hobby in its regards seeing your interests)

Let me know if you want more ideas and have fun and have a nice day man!

I had a route around San Francisco that I would visit, and all the places on the route were where there were good blackberry bushes. I’d take a bucket. Around Golden Gate Park and the Inner Sunset mostly, heading down into the Forest Hills area as well. I did that for a few years. Would pick up some plums along the way as well.

Now on the other side of the Bay I have a couple spots, not as dense a network. About an hour away there are masses.
