Restoring and collecting mechanical calculating machines and slide rules. I was abysmal in math at school, but I love those implements.

I can ramble about a few things:

• AI - very new, unconventional, scary, interesting and fascinating in a lot of different ways, mostly in ways most ppl don't really think about
• US Law - I'm european and I'm not a lawyer in any shape or form but Depp v Heard sucked me in and now I have so much knowledge about the US law that it's flowing out of my brain every once in a while
• Computer Science - with varying degrees of proficiency, obv things like software dev, game Dev, stuff like 3d composition, music production, but also some more specific ones like pentesting, some cryptography or scripting.

Fiber arts: popular ones like knitting and crocheting, but I also have a spinning wheel and really enjoy spinning yarn. I used to have a loom, but I didn't really enjoy weaving so I sold it. Lately I've been really in to darning socks and visible mending generally. Fortunately there are tons of fiber arts meetups and online communities so it's easy to find other people who are into any niche area.

I like socks. All kinds. Footie socks, ankle, calf length, knee high, thigh high, stockings... I've only just realized this in the last year or so but now I'm constantly wearing fun socks.

Is your flashlight molded after anyone though?

My brother loves o lights I think they're called, apparently there's like a whole community for just buying and selling this specific type of light so you aren't alone XD for me I love Rubik's cube type puzzles and lightsabers, I've made my own lightsabers and code in my own lights :) I feel like my friends are tired of hearing me talk about it XD

I don't know that it's unique, but I never actually stop modding Skyrim. Wife always asks, "Still modding Skyrim?", and I always answer with some lie like, "Yeah, but I'm finally on the home stretch here."

I have a dozen different hobbies, but I was really into flashlights for a while too. I was into them enough that my wife asked me to stop buying more flashlights and lanterns. I didn't stop though! I only stopped when I finally decided I had scratched that itch, have obtained what I want, and was bored. But now I have great flashlights in both of our cars, in my mom's car, one at each exterior door of the house, one at the garage door, and a few lanterns in the closet. She very much appreciates the fruits of my labors now that I'm finished.

• Photography. Analogue or digital.
• Computing.
• Electronics.
• Music, learning how to play and read sheet music.
• Bushcraft.
• Hockey.
• Pens, collecting stationery.

Lockpicking isn't just for committing crimes! It's a whole hobby! You can't prove that I've ever picked open a lock to get into someone's apartment... Mainly because I still can't get into this damn Abus 72/40, let alone trying someone's front door

If you want something I can talk to you about for hours, get me started on Kerbal Space Program. You know, there's really no "getting good" at KSP, only learning, and for all the planets and moons, there are only like five challenges: Taking off without blowing up, getting to orbit, orbiting the Mün, landing on the Mün, orbiting Minmus, and landing on Duna. Each of those requires a bit more knowledge than the last, and everything after those is just a remix of what you learn from those. To get to orbit, you have to take off successfully. To get to the Mün you have to learn about transfer windows and bi-impulsive transfers. To land on the Mün you need to build a ship capable of getting to and landing on the Mün. To get to Minmus, you need to learn how to match inclinations. To land on Duna you need to learn how to do all of that, but on an interplanetary scale. Everything else–landing on Dres, the Jool 5, returning from Eve–it's all just more advanced versions of those five things.

Of course, there's skill in making these missions as cheap as possible, as low part count as possible, as complicated as possible (see Matt Lowne's YouTube channel), and there are SSTOs to figure out, but ultimately the game itself is about exploring, and to do that you just need to learn those five things. This is just one of many rants I can go on about the game

I race RC cars. 1/10 scale outdoor and 1/28 scale indoor. Both on-road.

I also help run the club that sets up the races.

Pinball machines. And what they say is true, they’re expensive to maintain and nobody only owns 1.

Homebrewing. I have a little brewery setup and a 3 keg kegerator I made out of a fridge. I'm probably going to brew a chocolate porter thisnmorning

Warframe. I've been with the game since it's founding and find it to be a blast. The evolving story as they tried out new things and reworking core mechanics with huge improvements is just something I deeply enjoy.
