Might as well link the Technology Connections video already.
Yes, it's an 18 minutes video on a 1950s toaster, you can thank me later.

It's Technology Connections.
It's always worth it. Because
His video on the wok induction heater had so much sass
"What was once an impossibility is now a reality"
S-trap / P-trap (Eg in sinks and toilets)
And zip ties 👍
Pretty much anything with an interplay of water and air pressure fascinates me. Someone else mentioned siphons. I'll mention diving bells and bongs.
Sharpening stones.
you need an edge so many times in your life. When you're using scissors, slicing veggies, pruning trees, harvesting mushrooms, posting online, mowing grass, carving wood, cutting roots, trimming nails, scraping stoves/ovens, shaving, digging, trimming, pealing whatever.
There are so many dumb fancy arse awful tools that butcher edges and work in one specific case. No! For millenia people have been grinding edges, it is not difficult to learn it just takes practice.
Modern manufacturing means we can enjoy extremely consistent stones in well characterised grades. Go use some, and enjoy how much less effort life requires when everything that cuts, cuts easily.
So what should I look for when buying a sharpening stone? I was planning to buy one to sharpen the knives we have at home, but not sure what I should get and where to get one for a decent price.
you usually work up grits. In general for edges that should end shaving sharp (e.g. kitchen, whirling) below 1k is rough work, profiling work, 1k or so is basic small chip repair etc, 3k is standard sharpen, and higher is polishing wank. You get what you pay for in general: cheap stones need soaking, the wear out fast (needing truing). Shapton makes some great splash and go stones.
However, there is one cheap 2 sided diamond stone that is actually quality. The sharpal one. Be aware diamond cuts extremely fast (good and bad), it doesn't need truing or soaking. I recommend if you're getting one stone get that. Learn proper bur minimisation technique and that'll cover chip repair and get your knives sharp enough to cut seethrough sheets of tomato.
If you feel fancy add 1 micron stropping compound and a sheet of balsa wood to strop on.
On that topic, if you are in a squeeze and don't have a sharpening stone in the kitchen, you can use the bottom rim of a ceramic mug to sharpen a kitchen knife
Wheels are pretty cool
Vaccines.
They just taste so damn good
That's hardly low tech, especially not the newer ones.
Lathes. You spin a thing and cut it, which sounds unimpressive, but from there you can bootstrap to pretty much all modern technology.
Or, alternatively, you can bootstrap into a fine red mist as you get stuck to it and violently flung about
Lathes rule
Yes, when bootstrapping, tuck in your bootstraps.
To add a bit of detail, it comes down to circles being nice, simple geometric objects, and an assembly of metal with contact points being capable of way more accuracy than you'd first expect.
Bootstrapping the first lathe is harder; most likely some historical elite master craftsman was able to make one freehand, and future ones derived from it. We still have the one Vaucanson made that way, although it sounds like it was a one-off. David Gingery wrote a book on the topic, but he still assumes you have a power drill and a ready-made threaded rod.
Manual can openers are better than electric can openers
Especially the kind that uncrimps the can instead of cuts it.
String/rope. With a couple of knots, loops and tension you can make a lot of things with it.
Knives.
About as low tech as it gets, even for modern knives that are pretty high tech in how they're made.
But it's entirely possible for a person to make a knife with nothing but tools they can make by hand, with no need for anything other than rocks as tools. I've done it, and it isn't like I'm some kind of super genius.
You can make slightly more high tech tools if you want, and make metal knives. The caveat to that is that you have to know how to identify sources for the metal in the first place, unlike stone tools where you can figure it out by banging rocks together until you find some that make sharp edges. But making an oven that can turn out low-grade materials is realistic for a single person to do.
But a knife, in its essence is just an inclined plane done to a very fine degree. Doesn't get any more low tech than that. Mind you, there's plenty of complexity involved in all of the basic machines like inclined planes, but that's more about understanding them than using them or making them.
Knives are mankind's most important tool. They were among our first tools, and it can be argued that they were our first manufactured tools. And we still use them regularly. Some of us use them every day, multiple times a day.
That's a lasting technology in every degree of refinement.
Honestly, kind of mind blowing even thinking of them as a technology, they're so ubiquitous. I use a knife a minimum of 10 times a day, and that's just in the kitchen, not including opening mail, packages, small medical stuff, and a ton more uses. Holy shit, where would we be without those inclined edges?
Awesome comment to read at 430 in the morning. Thank you
Do vinyl records count? I really like that they make beautiful noise from a simple electromechanical process.
There are some records which are "threaded" backwards, in that you start at the center and work out rather than start at the edge and work in. This is not standard, automatic turntables might not be able to handle this, but the reason they do this is because of the effect above. You can get greater dynamic range near the outside of the disc, and you probably want greater dynamic range near the end of the recording as the music reaches a climax. Consider Ravel's Bolero, which is one long crescendo.
INDOOR PLUMBING
I live in an apartment complex. The thought of having to share an outhouse (more than 1 if lucky) with hundreds of strangers TERRIFIES ME. And/or use chamberpots. FUCK NO
A BLESSED ETERNAL AFTERLIFE OF BLISS FOR ALL HUMANS WHO CONTRIBUTED TO INDOOR PLUMBING SCIENCE 😩
Bicycle
Rock.
Dice.
Rope or really any cordage. Can't begin to tell you how handy learning 7-10ish knots has come, plus lashings
I was always terrible with knots growing up. My father spent far too much time trying to teach me a basic trucker's hitch and sadly never got to see me really "get it". Then, when my own son was in Cub Scouts and supposed to learn some basic knots, something just clicked in my mind and I took an interest. The bowline was the gateway knot for me and learning that led me to finally apply myself to the trucker's hitch. Just such a useful pair for tying up a load. I can understand why my father really wanted me to learn it.
Now, I keep a length of paracord on my desk and will fiddle with it, practicing knots whenever I'm doing something that leaves my hands free. And ya, having a basic set of knots down is just damned handy.
Books
I like to get all up in my snuggie. Get a little weird.
Siphons
Automatic (mechanical) wristwatches.
I love the idea of a truly symbiotic relationship between a thoughtfully and carefully designed mechanism and a human. I walk around and live my life, and by doing so, I give it the kinetic energy it needs to keep its mainspring wound, and in return it tells me what time it is. Always. Without fail. I just have to tweak the time if it starts to get too far off, but that’s barely even an imposition. After a good long while, it’s prudent to have them serviced, but if you’re not observing any problems, it’s generally perfectly fine, and will keep ticking along as long as you wear it regularly.
Rice cookers. It's super low tech but works great to cook perfect rice.
Axes, I have four and I will get another next year.
I have a hatchet for small tasks, a midsized axe for cutting small trees down and chopping, a Pulaski for landscaping/ digging tasks and I have a splitting axe/maul for splitting rounds.
There is something incredibly rewarding and fun about swinging an axe.
I bought a can opener years back that doesn't cut the can, instead it separates the lid from the can with no sharp edges. It's dumb but I love it.
Hand tool woodworking. It's amazing what you can make without a single electron. Its also amazing to feel the tools, the resistance and subtle vibrations as you use them. Like an extension of your own body. I love chiseling, especially large mortises. Hearing that sharp, deep thud, and seeing it sink in as it bites into the wood is so satisfying. Especially when using metal hammers, they are so responsive.
I love sawing, especially when relaxed and working at a slow pace, seeing all the sawdust fly out with each stroke. Sawing isn't fun when working on difficult pieces of wood, when working in a relaxed manner with softwood, the hoarse sounds of the saw starts to sound like purring and it begins to cut exceptionally well.
I love the finish of handplanes, so smooth it becomes water resistant.
Overall very spiritual and relaxing (as relaxing as you allow it to be at least)
Waterwheels. Thousands of years old but still an essential part of our energy system.
Wood working ? Whoever craftsman who first makes a stringed-instrument, compared to a piano an acoustic guitar is a relatively simple instrument and it gives me endless joy even without company or electricity.
Dumb TVs. I love the option to turn it into a pseudo-smart TV with just a streaming stick. But, I'm always okay with a TV that just has the ports for basic things.
