Ask HN: Any interesting niche hobbies?

483 points by e-topy ↗ HN
I'm looking for something novel and interesting, that isn't absolutely crowded that I could meaningfully contribute to.

In 2022 I was toying around with OpenAI's RL Gym, right when the first non-instruct GPT3 model came out. I was thinking about getting into ML a lot more, but hesitated. Before that it was 3D printers, mechanical keyboards, drones, etc. All of these have exploded, and while they are still very interesting, I do love my Browns and manage Prusas for my local hackerspace, they have just, for the lack of a better term, industrialized. I'm also now in a position where I have time and money for it, not like when I was 15 and rating Ender motherboard upgrades I knew I'd never buy.

Right now I'm making a chess engine, but that's already a solved problem. There's also biohacking, and while designing chips to go into my body is really interesting, I only have one, and don't want to push it too far. One promising idea is a kind of 'Personal Computer 2', where people try to innovate HCI, and while I really like that and do have some research ideas, I'd like to explore a bit more before delving deep into it.

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!

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.

I'm on the other side of this, in that I attend a lot of these.

I made a big effort about 12 years ago to go to a bunch of these (like three meetups a week and trying out a variety of different meetups), but now I mostly stick to a couple of them as I don't have as much time or energy for it anymore. But I've met most of my current friends through those meetups.

Find one you like and keep showing up until you're a regular, and get to know people slowly, and if they like you they start inviting you to things outside of the meetup, and then eventually you end up being friends.

I've done this with three different groups over the years and despite naturally being shy and an introvert I've ended up making friends at each one.

At the height of me doing this (like ten years ago), it got to the point where I'd go about my daily life and about once every other month I'd run into random people I've met at meetups also out and about. Like go out to dinner and spot someone I knew from a meetup also showing up to the same place, or run into them shopping at a Best Buy or something.

Meetups where you do a shared activity seems to be the best, like hikes or movies (+ dinner afterwards) or board games, since you can always focus on the activity if you don't feel like being social, and you have that activity you can always talk about as a subject.

> 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.

How have you handled this in past meetups?

Be courteous, kind, don't accept invites, tell them you're not interested if they're making unwanted advances, and treat them as humans. If they seem receptive and able to handle constructive feedback, tell them what sticks out to you, otherwise just ignore it and move on.

Basically the same way you handle the exact same situation outside of organizing meetups, but maybe a bit extra on the friendly-and-try-to-not-traumatize-people-who-might-be-trying side of things.

`embedding-shape` answered it better than I could have, but I will add: I "ban" people from meetups who are overall bad for the group.

E.g. people who register to take up a (free) spot and then don't show up after multiple reminders, people who are especially rude to somebody fragile, even people who are unconstructively / loudly negative (picture the equivalent of walking into an auditorium of 800+ people, picking up the microphone on stage to yell "this meetup sucks!" then walking out).

This policy is controversial and I'm always trying to find the balance between being as welcoming as possible to people who aren't neurotypical or are going through a hard time and need the social interaction (e.g. me, multiple times in my life)... and people who just come off as jerks and are a net negative to the group.

I'm in multiple groups myself and I always measure myself by whether my showing up that day was a net positive, neutral or a net negative. If the latter, I don't belong there... at least not until I fix whatever was wrong.

What are the meetup themes? What brings the interesting people in?
I organise events as well and I'm wondering if you ever charged for them. I used to do them for free but so many people signed up and didn't attend later that it was hard to put numbers to book a venue to meet. How did you solve this?
i would do free venues only. usually restaurants are free because you consume food. if that is not an option, it depends on the cost. i have seen events where people were asked to contribute something when they arrive. you can usually announce the cost of the venue and ask everyone to contribute appropriately. if you fall short then next time ask people to contribute more. or keep a running tally during the event until the venue cost is met. from my personal feeling, if it costs more than $1-2 per person the venue is too expensive. find a cheaper one.

I use Blood on the Clocktower to do this, it's a social deduction game (that's just not randomly accusing each other) so it gets everyone talking easily
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".
Sounds like a really cool idea. How do you organize the meetup and promote it to people if it ends up being random people? Do you set it up on meetup.com and have a theme at the minimum?

I've been to a lot of meetups and it's definitely hit or miss and obviously depends on the sociability of the people that show up. The better ones I've attended are generally ones where people aren't trying to network for work purposes and are there literally to just socialize. The networking ones I find very dull as it's people just talking shop and career and if you've nothing to offer them on the career front, they move on quickly.

Write explicit rules about dogs. Many "weirdos" just like their boundaries and basic hygiene. It is hard to socialize, over barking contest and rar dog humpimg your leg.

It will save both sides a lot of time.

> 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.

Yep, thats me.

We all find different people weird. You just need to find the weirdos you vibe with.
What locations do you recommend to emulate this? Coffee shops / libraries / your home?
Have you done any write ups about how best to go about doing something like this?

I'd love to organize something like this in my local community but somehow am not sure where or how to start really.

In German speaking areas there's an app called Spontacts where one can advertise any sorts of events and people can sign up. Like MeetUp but free and it actually works. Lots of people offer board games, walks, brunch. I got into it recently advertising spontaneous ping pong get togethers. Met some really cool people so far.

Thanks for unlocking a new anxiety for me.

Similarly, I did group therapy for a few years, and found it highly and profoundly rewarding.

It's much more structured, with a facilitator to help reduce the possibility of dangerous behaviours. It forced me to confront aspects of myself I otherwise might never have. It also (I think) gave me greater insight into what might be behind people's public faces.

I can confirm that this is a great hobby. I did a weekly meet up, man, nearly 20 years ago, which was at the same time and place every week, and we (me and the core clique which consolidated within a month) advertised it on Twitter, which was niche enough at the time that you’d get a bunch of interesting weirdos showing up.

It’s how I met my wife, how I met a whole bunch of people who still feature in my life decades on, how businesses got started, and so much came out of it for everyone involved. It probably helped that we did it over beer and burgers, as one was a social lubricant and the other robbed people of an excuse to leave early. Plus afterwards it transformed into poker back at my place, which was how I really got to know people fast.

Talking to strangers is fun - as is figuring out which strangers will like which other weirdos you’ve got to know and buddy them up.

My hobby is also going to the pub.

Same, i do the same.. it helps me learn new things, make friends.
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.

My brother-in-law did a lot of hang gliding, and was part of a big community that did.

That community had a tendency to walk around - if they could walk around - in casts for a large part of their life.

He also ended up having a heart attack mid-glide, which was no fun at all. (He survived it, though!)

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?

https://vibegenealogy.ai/p/the-genealogical-research-assista...

The use of AI assistants in genealogy is interesting. There seems to be a lot of activity in that area
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 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.
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.

(comment deleted)
HCI innovation is definitely an interesting hobby - anything you can share or point me towards?
> 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 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.

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.

I want to hear more
That's pretty neat, and we should talk. In my household we are currently producing about 75% of our clothing, mostly out of a desire to avoid using fabrics that generate a lot of microplastic waste + observing that newer clothes/fabrics wear out quickly.
How did you start out? Was it through local classes?
No classes. I was probably hyper aware of how my body reacts to clothing.

For example, the waist of almost every pant became uncomfortable when I sat down after eating food.

The area below arm pits and close to thighs was always tight. The length of pants was always long for the waist.

- To determine my taste, I looked at various styles of women clothing (on Pinterest).

Then for the models I found most attractive, I imagined what would the clothes they have put on look like if they were men. That led me to the realisation that I like formal aesthetic, reserved and subtle colors.

Everything else was experimental

Hey, I looked you up online and ... you dress real well! Congratulations!
OK, fairly specific question - how did You get to that pants silouhete? It seems from the pics You went for something like a straight leg plus some extra room and fairly fitted waist / butt. Is that a response to a trend (oversized work clothes seem to be the thing these past few years), or is there some practical reason too (mainly for the extra room in the leg shape)?
Two reasons: 1. My thighs are bigger than usual for my waist size, so I adapted. 2. Indians (Bharat) have a culture of wearing lose clothes, and I also like lose clothes. They are more comfortable.

The waist is fitted, but with elastic bands on the side for added comfort (my belly gets bigger during evening, when I sit down and after I eat).

hell yeah, I have tailed my T-shirts before but nothing else, making my own sound like a nice challenge.

How do you source materials? I'm usually very picky about the material, especially if it touches my skin, and usually the heavier the better. The best T-shirts I ever owned was a military surplus made from organic cotton, and was more than twice the weight of my other T-shirts, but I couldn't find anything like it anywhere.

This is super cool. I also find it hard to the right fit for me so I usually end up at a tailor or wear baggy clothes(which are in trend) however the comfort of having the clothes fit you right and you feeling really good about is missing and fast fashion sucks too lot of poorly designed clothes and cheap materials that becomes generic quite fast.

Kudos for living this lifestyle, those pants look really sick..

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

This is very cool. Thank you. ...and that video is a pill-quality destressor. thanks again.
I love how every hobby has its inner nested hobbies and you can seemingly go infinitely deep.

I got back into making electronic music a while ago, and you can dig in deeper by getting into hardware synthesizers. And go deeper by getting into hardware modular synths. And go deeper by building modules from kits. And go deeper by learning electronics and designing your own modules.

It's like a big branching tech tree or tech graph.

With fishing, you can get into fly fishing. And when that's too easy, you start tying flies, or maybe tenkara, or, I guess in your case, making fly rods.

I love it.

> If you try to buy a bamboo rod in a store, they run $2K-$5K.

I got a bunch of cane[0] rods off eBay for relatively cheap[2] (but that was ~2010.) Sadly my fishing activities were strongly curtailed around 2012[1] (due to a family divorce) but I'm hoping to get back to it one day.

When I did get a chance to use them, they were much nicer (to me) than my companion's fancy new rods (even if the bend when fighting a fish was absolutely terrifying.)

[0] I'm not sure if there's any bamboo ones - it's been a while since I've seen them due to [1]

[2] Inspired, as many people are, by Chris Yates.

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. )

If it is a Thames Water area, you are lucky if the leak is only water...
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.

Only problem is this really depends on where you live. There is a nice museum 45 minutes from me - far enough that it is hard to get there for a quick evening after work...
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 can play with sensors (acidity, humidity etc)

Can you share some useful sensors? Any good pH sensor that can work for some period of time without manual maintenance (cleaning the probes etc)?

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.

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.

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 :)

Oh yeah I've made some designs for a custom Eurorack style synth, but I quickly realized how expensive it would be to make a full rack. A synth scales exponentially, to get even some usefulness requires getting a lot of modules. Maybe one day.
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.

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 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.

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