Synthesizers! I like it because it's tactile and immediate, and you're not glued to a screen, but can create fun-sounding beats.
Nowadays there are nice, cheapish groove boxes that are perfect for noodling on the couch. I started with the Novation Circuit Tracks, and also really enjoy the Teenage Engineering EP-133. Not to say that I am any good at this, but it's an enjoyable hobby! Bonus if you are friends who are also into it and you can jam together :)
Go to modular meets, music instrument expos like Superbooth, dj sets and live concerts.
I met all my best friends this way, everybody is a record collector, beat maker or techno producer.
Record conventions are also fun, after couple of occasions you will realize how small the scene is.
Deep in the Eurorack rabbit hole myself. Trying to avoid anything that has a screen and anything that requires a computer to interact with. Patching cables and twiddling knobs is great fun. Sometimes it even sounds good xD
Oh yeah I've made some designs for a custom Eurorack style synth, but I quickly realized how expensive it would be to make a full rack.
A synth scales exponentially, to get even some usefulness requires getting a lot of modules. Maybe one day.
