my cheap ass salvaged speakers. I got them from a friend who got them from her father who got them from a school janitor who got them from a school that was throwing them out. Each of those step did some “repair”, until they got to me and my roommate, and we undid every previous “repair”. we are still using them

Possibly my dingy. It’s a eighties fibreglass boat. I’d feel super comfortable swapping any part of the rig and doing light repairs on sail or hul. Although, if the mast broke or the hull was badly damaged I would probably have to let it go ):

Also, on the topic of boats. That one isn’t my boat, but I somewhat frequently sail a stjärnbåt, a type of smaller wooden boat. There we have a real ship of Theseus situation, I think there’s no part of that boat we couldn’t repair.

Do they stink? Like, old vacuums got stink like the shit they’ve been sucking up for years. How do you fix that?

I don’t have it anymore (sadly), but for a while I owned a Hitachi TX200 projector.

All of the fans were standard PC fans and easily replaceable. The polarization filters came on little extra modules, you could take them out, replace them and realign them easily. The service menu had an option to shift the pixels for each individual LCD to counteract for pixel-drift and you were also able to calibrate the colors for multiple zones. It’s a great projector and can run for many years with a few replacement parts.

Sadly, it was only 720p and Hitachi never made a higher-resolution model. :(

Guitars. I have more than enough, but I still cant resist a good deal on a dirty, old, neglected vintage guitar. Clean it up, fix up any problems, re-string it, play it for a while, and sell it. But if it’s better than something I’ve already got, then I’ll keep it and sell the old one.

I’m slowly building and improving my stable, without spending much money at all. It means my guitars probably won’t say Martin, or Taylor, or Gibson, or Fender, but they’ll all be excellent guitars anyway.

I’m also good with dryers. There isn’t anything on a dryer I can’t fix. They can almost be a Ship of Theseus situation.

Probably hand planes, I can easily keep those going for decades myself.

Some of my furniture I guess, I’ve already rebuilt the bookshelf that fell apart.

My oven (AEG/Electrux)

And my Volvo V70, 25 years old and only minor and wearable parts replaced.

I have a reusable bag. I repaired the seams at least 6 times.
I really love the bag, I got it from CES about 7 years ago. And even it’s an evil entity now, it is hands down the best reusable shopping bag I own.

My Thinkpad:

Me.
A lot has and continues to go wrong, but mostly self-repairing. At some point some failure will be unrecoverable, but hopefully that’s a long time in the future.

An even better answer might be my cats. The small number of repairs that need professional assistance are cheaper than the same issues would be for myself. However I don’t expect them to last as long, unfortunately. Even though I got them very nearly brand new a few years ago.

3d printer. Just wish I didn’t have to do it so often.

My Rancilio Silvia espresso machine. Easy to take apart and replace anything. Parts are readily available from many sources. Also, my BMW 3 series, but I’m a BMW tech, so I better be able to fix anything on it. But it’s 14 years old and is like working on a horse cart compared to the current ones. Luckily BMW are designed to be able to fix anything on them, unlike most other brands. Don’t even get me started on Tesla, what absolute junk.

I’m pretty good at repairing computers, but please don’t tell my friends and family.

everything i own is repairable because i end up buying decade worth of equipment.
