Electronics repair and projects

For me it was Badminton. You can start off with cheap $15 rackets and plastic shuttlecocks. Now my racket is $260 and I play with feather shuttlecocks which are about $2 a piece and only last a few rallies.

Instant (analog) photography and collecting pins and buttons. Turns out film is expensive and buying pins are expensive. Started out with friends giving me pins to stick on my bag and now I have close to hundred pins on my pin wall. At least they look pretty rad.

Fountainpens. Started with some cheap Chinese pens. Now I have multiple vintage pens and a Montblanc that I love writing with.

Coffee for sure, never saw myself owning a $300 coffee grinder a few years ago....

Smart phones and headphones aren't exactly cheap but, I have built a bit of an expensive hobby around collecting them lol

Knitting/crocheting and cannabis. Not (always) together. Yarn art to pass the time while sitting with my mom - I start a lot of things and always need new yarn, but I never finish anything. Cannabis because I started making candies for a sick friend and it's pretty easy to get caught up in different strains and what's on sale this week.

Collecting vinyl records. I started 10 years ago when you could get lots of records for 3-5$ per record. Now everyone is crazy about collecting and they can cost 40-50$. Was a great investment if I sell them. But I enjoyed collecting them regardless of value.

Collecting military surplus/old random military shit. Helmets, great coats, radios, a field phone, ww2 machete. Ya get the idea.

Running as soon as I discovered the Runningshowgeeks subreddit.
