I revisited an old hobby, emulating niche systems. I got an Acorn emulator with Risc OS 5 and some development tools, and I wrote a snake game in BBC BASIC and a calculator in pure ARM assembly, both of which are new to me. It was a blast.

I play rhythm games. Like a lot. Maybe to many?

Longboarding is a hobby I picked up a few years ago and it’s a ton of fun. Just riding along you feel like you’re floating over the pavement and the feeling is addicting. You can get e-boards if you’re not into pushing but I haven’t gone down that road yet since they seem heavier and more expensive. Also, most of them you can’t push and you have to rely on your battery and motor so if you run out m, you’re stuck. Some companies like the one I bought my board from (Bustin) make hybrid boards but they’re pricey.

Code golf on the cgcc stack exchange. I don't do it too often, but the community is pretty small and when I see a good one I can't stop thinking about it.

Brickfilming! I make films with Lego using stop motion animation. Takes a lot of patience and my perfectionism is my worst enemy, but it's super rewarding, and there's a really cool community online around it. And yes, my profile picture is from my most recent Brickfilm!

I guess blacksmithing would be considered niche? Not doing it very regular. But once every view months.

I'm really into calligraphy and snowboarding. Luckily there's a snowboarding presence here on lemmy, but I have not the time to start a calligraphy one.

Yarn dyeing started as a hobby and turned into my job quite quickly :)

It's fun and satisfying to see the colours evolve on yarn and how the colours act differently depending on the fibre blend you're dyeing.

I collect plushies/stuffed animals (to the point where I'm running out of room for more) and I've played Tabletop RPG games like Pathfinder, Shadowrun and GURPS for a good few years.
