Edit: so it turns out that every hobby can be expensive if you do it long enough.
Also I love how you talk about your hobby as some addicts.
Electronics / microcontrollers.
Took just a few months to go from, “I can make a wifi connected weather station for like $20 in components!?” to “oscilloscopes cost how much?”
Has there already grown a noteworthy Arduino/ESP Community on Lemmy?
There are quite a few but none are super active.
I would love to read about this $20 weather station! Do you maybe have a link?
Mine is pretty basic but is built on the shoulders of giants. Also that $20 was from pre-pandemic / pre-chip shortage prices. I’m guessing it’s more like $35 now, or maybe high $20s from ali express.
I use Home Assistant for home automation. It has a now official addon called ESPHome for easily configuring esp devices and adding them to Home Assistant.
I bought some cheap dev boards off amazon and thankfully they worked an esp8266 microcontroller with IC2 headers and a microusb port already onboard a bmp280 that measures temp, humidity, and barometric pressure a lux sensor with a plastic dome over the top I soldered them together on a prototyping boardAll the components were supported by esphome, so I just needed to write the device config and then flash the devboard via esphome (in a web browser) over the built in usb.
I 3d printed a housing for it, but you can also buy boxes. It needs airflow but also needs to stay dry. You can use a spray sealant to help avoid corrosion from ambient humidity. I skipped that step because I want to see how quickly it becomes problematic… and I should probably check on that.
Just an fyi bmp280 is not real temperature but an estimation based on air pressure.
Self-hosting apps / homelab
Getting used enterprise gear is not prohibitively expensive, but the electric bills balloon very quickly.
I currently bought an old desktop from a friend that I use as my Homeserver.
- I bought 3 HDDs for storage
- I rent a VPS
- I rented Proton to host mail for my domain, but switched to netcup groupware because that sucked.
- Some domains
- Electricity
Wow I thought it was way more.
One time costs: ~500€ Monthly costs: ~15€ Plus electricity, but I have solar. I assume it’s about 150€/year
But I’m a cheap selfhosted, but eventually, I will have a huge ass Enterprise Level Rack in my basement.
Coffee.
I blame James Hoffman entirely.
Within a year I went from:
Drinking instant coffee at home, but really enjoying “proper coffee”
To
Buying a cafetiere (~£15) + preground coffee
To
Buying a Nespresso (~£60 on offer) + pods
To
Buying a budget espresso machine (~£120) + preground coffee
To
Wasting my money on a cheap manual coffee grinder (~£50) + beans
To
Immediately replacing it with an entry level Sage grinder (~£170)
To
Buying an entry Level “proper” espresso machine (~£700)
It took me a good 2-3 weeks of practicing and dialling in before pulling a good shot of coffee that I’d actually want to drink, but by that point it was also about learning a new skill, learning how different aspects of the process affect the end result and learning how to make all sorts of different espresso-based drinks.
My girlfriend thought I was nuts at first, but a year or so later even she agrees it was worth the investment. I still for the life of me can’t get the hang of latte art though.
The problem is now though that I’m a waaaay more critical of coffee from coffee shops, because I spent a long time making bad coffee whilst learning!
Espresso is the line I won’t let myself cross (and I don’t have the counter space lol), but the $350 for the Kinu M47 was hard to swallow.
Plus side, it’s also a great espresso grinder if I do ever eventually head down that road.
Growing cannabis (legal here in Canada)
…anyone can grow weed. Growing GOOD weed is an art.
I unintentionally grow weed because I made some tincture for grandma.
Now it just grows on my garden and I can’t get rid of it.
2000 into my fully automated hydroponic weed factory. Another 500 to make my nutrient solutions from scratch. Mind you that 500 dollars when making from scratch likely last 20 years of crops. It does make a good 1.5 pounds of dry weed every 3 to 4 months with the for legal plants allowed in Canada. I barely smoke so give nearly all away.
Three year prior, harvested a crop down right before going to Mexico for three month trip. Was still some shoots barely growing so for shits and giggles I turn the lights back to 22 hours per day to see if they would go back to the veg state. Have camera so can watch it remotely. Shit starts fully growing like a new plant. Anyhow COVID puts a wrinkle in my return. Ended up in Mexico for 18 months. Over that time, thing kept growing like nuts. Automation on water replacement and nutrient injection along with pH monitoring. Became sort of a how long can this thing go with near zero human intervention. Had only to send my brother in law in three times to cut it down and refill my nutrient injectors from solutions I made before leaving.
Knitting. Super cheap to start, you can pick up a set of needles and some acrylic yarn for under $20. But when you start getting into nice yarns and bigger pieces, you are spending hundreds of dollars on yarn alone for a blanket or a sweater. And you want nice needles in all sizes as well as all types (double pointed, regular and circular)… more hundreds of dollars.
Moral of the story is if a friend knits you something with nice yarn, please appreciate it. Lots of effort and thought went into it.
Just started crocheting, and I’m just holding myself back from buying all the yarn, it’s gonna get bad
My mom knits and she spends way more time unraveling thrift store finds to salvage the yarn than she does actually knitting stuff.
I bought myself a raspberry pi for my birthday a few years ago.
I now have thousands of dollars in hardware sitting in a server rack in my office. Whoops.
A single 1TB drive should be enough for my Plex server, I said.
123TB isn’t enough, I need more 18TB hard drives, I said.
Running.
Was supposed to be the cheapest way to get exercise. You can do it right from your front door, no gym subscriptions, no specialized equipment (some people will tell you you don’t even need shoes), and it’s far and away the best time-value exercise I’ve ever found. You can get away with like 20 minutes 3-4 times a week and be doing great.
Well, turns out I love running and I love distance running so I’m now putting up enough miles to need new shoes 2-3 times a year, a nice Garmin smart watch and heart rate monitor to track my progress, sign-ups for several long-distance races each year, shorts, socks, you get the picture.
Could I do it cheaper? Yeah. But at the end of the day it’s a hobby and I like it
You realize it’s an addiction when you intend to do 5k. Realize after that Strava didn’t work properly on your watch and then you end up doing a second 5k because the first 5k didn’t count.
Finish marathon
Legs on fire
Garmin says you only ran 25.6 miles
Have to run another half mile at race pace (so you don’t ruin your stats) to make sure you get credit for a marathon
I was running for a couple of years , and my knee started to give me problems.
I went to an orthopedic Dr, and his advice was to take up swimming and if I wanted to keep running that I should hold on to his business card because someone needed to pay for his kids’ college.
I stopped running soon after and avoided surgery for a decade, but it still caught up with me. Knees are definitely cheap with for-profit healthcare.
For me it is maybe camping.
I just tested my new sleeping bag - under 0.5kg rated to -5°C. And realised that I bought/ replaced lots of gear to higher quality gear over few years.
Camp stoves and fuel! I can buy a lot of bic lighters and cheap metal camping mugs for the cost of a dang Jetboil stove and fuel.
Board games. Things get expensive once you start collecting
Coffee. I’m in a coffee producing country. It could be as cheap as grabbing a bag from the coffee institute (really good and cheap), a cloth filter and call it a day. Instead, I’m on my second espresso machine, fourth grinder, second portafilter set, and have all the doodads to make it just how I like it.
I needed a new saucepan.
I’ve now replaced half my kitchen.
Watercolor.
Children play with $5 palettes. Apparently I pay $20 for a single color tube.
Gardening.
Containers are surprisingly expensive. And you need a lot of soil to fill them, which gets expensive too. Then it’s impossible to only buy the seeds you need, when there are so many cool varieties…
This is not the first post where I feel it but I love it so much that we have a lot of people on Lemmy that can talk about things not related to computers!
It’s a toss up between cooking and home networking for me.
Cooking because it started off as just finding neat recipes and giving them a shot to now experimenting with new techniques and harder to procure ingredients. My pantry looks like a mini spice market and keeping them fresh is its own hassle. Plus needing all the gear gets expensive!
I also got really into home networking during the start of the pandemic. I went from having a simple off the shelf mesh network to a full network rack in my basement serving some high end access points and cat6 drops in every room. Now I have a pretty secure iot stack that’s separate from my main vlan and one devoted to my work computer.
