This barely qualifies as a hobby, but at some point I decided to learn how to count in binary on my fingers. It’s handy if you need to hold a number in your head for a bit and can’t write things down, or to count past 10 visually on your fingers for somebody. There are probably YouTube videos on it. I literally can’t remember where I learned, but I practiced a lot when bored in church. It’s relatively non-disruptive and practicing can eat a decent amount of time.

0 materials. Just takes time. Literally free.
I’ve heard church frowns upon non-binary people. But I had no idea they convert people to binary counting.
I did the same when Masahiro Sakurai explained how to do so when revealing Byleth for Smash Bros. Ultimate. It’s come in handy a few times when needing to count things out, and honestly can be a fun exercise for dexterity to just count to 31 on each hand.
