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.
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
Great post OP!
PLANTS, LOTS OF THEM
Selfhosting media
Started out with a raspberry pi several years ago. Got my feet wet with entry level, beginner friendly NAS prebuilds. Hunted for recycled computer parts. Now searching for and actively acquiring enterprise gear that is making a massive dent in my wallet.
Data hoarding and self-hosting every service under the sun.
I will buy a Ubiquiti edge router to move away from the consumer grade network gear, turned into just one more $500 server to complete my homelab cluster. Oh who am I kidding the homelab is never “complete”.
My grandma got me 3 ducklings in 2019 for no reason. 3 ducks don’t cost very much. The issue is, that she unlocked a passion. I now have 12 ducks. I want more, but I don’t have the money or space.
selfhosting/homelab. Originally started just using retired gaming PC parts to build a server. All it cost was the power to run the system. Years later and with more things/content I have, I just added a 5x 18tb hard drives and 3x 8tb. Just the 5 18tb drives was like $1500.
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?”
