Instead of disposable plastic razors (Schick, Gilette, etc.) I recommend getting a safety razor and a big pack of blades (I use Merkur). You will save yourself thousands of dollars over the course of a lifetime - and avoid generating a ton of waste. Maintenance is pretty much just cleaning the razor with vinegar every few weeks. https://en.wikipedia.org/wiki/Safety_razor If you have the time/desire for it, a straight…

I've been using the same rechargeable Wahl clippers for about a decade and only shave with a razor on rare occasions because the clippers get close enough for most situations.

It's also possible to repair them to some extent. I've taken the body apart to clean it out, and it seems like it'd be easy enough to replace the battery.

I've repaired multiple gas stoves for people. The SiC element which heats up to ignite the gas fails over time. My neighbors were just replacing their stove every time this happened until I showed them how to do it.

Could I ask for some more info, I think I might be having the same issue?

PSA if you're thinking of repairing appliances that run on mains power supply:

A lot of you might be comfortable tinkering with breadboards or Arduinos and hobbyist electronics, but mains electricity can be lethal. Please consider hiring a professional electrician before you start replacing failing components or power cables if you're unsure about what you're doing.

Stay safe :)

Our 65" Samsung faded out (blue/purple). Just needed to replace the white back-light LEDs. $60 in parts. About 1h labour (mine).

How much time spent diagnosing the problem, researching the fix, and finding the right part? Also, what about the time spent learning all the info and knowledge necessary to be able to do the above? There is always more to the cost equation than immediately obvious.

The skills you learn doing it once make every subsequent repair quick and fairly easy. I've repaired multiple TVs at this point.

Earlier quoted context omitted.

Is that a relatively easy project for an average homeowner?

I’ve done it. It’s not a big job, but the issues I ran into were: 1. You need a specific and large socket wrench. (A big adjustable wrench wouldn’t work because the head was recessed.) 2. Mine was really stuck in there, so it took a lot of torque to get it loose. Had to get someone else to hold the water heater in place while I pulled on the wrench. 3. My water heater was up in the attic underneath the angled roof, a…

> 3. My water heater was up in the attic underneath the angled roof, and there wasn’t enough clearance to get the new one in. Got kind of sketchy tilting the water heater over so I could get it inserted.

I'm starting to think this is the real reason I pay people to fix things for me (if I don't do it myself). YouTube makes most fixable things pretty easy. It's the climbing over/under the house, getting in hard to reach places, etc... that makes a repair a pain.

I've dabbled in this a lot, and I don't consider myself a very handy person. Cell phones are much more repairable than they seem. You can replace screens, batteries, USB ports, antennas, etc. A new battery and factory reset makes it seem completely new. Laptops can often be repaired or upgraded, especially earlier MacBooks or current Dells. I've upgraded my old (2014?) MacBook pro and used it for daily use for years.…

I recently came across a free 2012 quad core Mac mini that ran, but kept failing to update to the latest OS it should support. Turned out to be a bad stick of RAM, pulled that out, popped in a cheap SATA 1TB ssd and used open core legacy patcher to bring it up to MacOS Monterey. Now it’s my home server/docker/VM runner. Hope I can get a few more years out of it although Ventura support through open core seems unlikely.

Admittedly, it took quite a while to diagnose the problems and get everything updated, but I consider that stuff a hobby.

Some relatively simple things I've repaired around our apartment. Not all of these people would replace, but they might call a professional when it's quicker and cheaper to DIY:

* Top-loading washing machine. If it spins really loudly, or stops spinning, pop off the front panel and check the belt. Ours had just slipped off. Just make sure you get it really tight when reattaching--I had to redo it a couple times until it stayed on. As a bonus, I found a bunch of clothes that had fallen inside, including my wife's favorite skirt :-)

* iPhone battery replacement. Just bought the iFixit toolkit and followed their guide, it was pretty simple. Extended the life of my 6s+ another year (so far).

* Clothes repairs are pretty simple. I've patched some pretty big holes in jeans with new fabric which is a bit more involved, but things like sewing buttons back on or patching small holes is really simple, just look up mending stitches online. If you don't have the right color of thread, you can use hidden stitches, or go for a kintsugi approach and make the mending visible which can be pretty stylish.

* Stove burner covers -- these literally pop out and are (usually) dishwasher safe.

* Dishwasher cleaning -- this isn't hard, but can be pretty gross if it hasn't been done in awhile. Look up a youtube video, take all the parts out and thoroughly scrub everywhere you can, then run a cycle with a couple dishwasher cleaning tabs. Night and day cleaning difference for old dishwashers.

Nice. I admittedly move to Linux when I upgrade these old macs.

A friend once got an old PowerPC iMac off eBay, and it perfectly ran Ubuntu 12.04 IIRC.

He set it up as a remote testbed for PPC benchmarking, since the Mars rovers use the same generation of PPC processors.

Oh, my holiday altercation with Kitchenaid brand stand mixers.

We have a Kitchenaid mixer. It came with aluminum whisks and dough hooks, which don't dishwash. So I splurged on a 150 dollar set of stainless steel upgrades. They arrived, and I test fit them - they attached! And being the wise, old, fool that I am, I discarded the original attachments in a ceremony over jack daniels laced eggnog.

So then, Christmas Eve, we go to attach them and whip up a bunch of dough to make puff pastry, which is how one might make a raspberry turnover. Alas, the little attachments are barely too small to reach the bowl! And so everything is asunder, a bowl of un-kneaded dough.

Fortunately we live in a country that really rewards consumerism, and so 75 minutes later on Christmas Eve itself, I was back from the store with a replacement Kitchenaid, the 'Artisan' series, which I wisely spent a brief moment verifying would double my sunk-cost fallacy in 150 dollar attachments.

I hop into the shower, and my wife starts kneading the 6 cups of dough. Our ceiling fan wafts air in from the kitchen, which generally ends a shower prematurely for wont of sprinting to confectionary delights. This time, I spelled a burning motor. A moment later, my hands were feeling the motor casing for heat: blistering hot! Of course, being an infrastructure engineer for the public cloud, I instantly knew that this was 'bad' and turned the device off quickly.

"Ahah!" I declared victory with a sardonic undertone, "This mixer voids the warranty for more than two cups of flour, with the speed above 'low', for any dough kneading!"

Well, we ended up going back to the Kitchenaid professional. It's got a speed control issue and needs a new controller board. The gearbox often breaks little gear bits off and also requires repair on these. And many of the newer models have a plastic cases that warps under extreme heat - some describe this as a safety design feature to protect the metal gears, and others say its a cheaper component and unintentional downgrade. Either way, the parts are user accessible and replaceable. People who rely on these devices will apparently keep extra parts in anticipation of their failure, to carry on with minimal downtime.

And yes, there is another box of 150 dollar attachments somewhere in the mail, to replace the aluminum ones I brazenly tossed into the recycling bin. And yes, I lost the packaging for the ones too-small. So my friend gets a set for his artisan I confirmed he randomly owns sheepishly, and I get the original functionality back; I end up with exactly what I had, plus also a lesson hard-earned, for the low cost of 300 dollars. There is no age limit on feeling dumb :D Happy Holidays

Sometimes the item is thrown away before it breaks. I was handed a 24 inch smart tv and told “nothing wrong with it, still works”. I dont think it is worth fixing everything that breaks, but maybe 30% of broken items by my estimate are easily repaired.
