Showerthoughts

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts:

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. No politics
    • If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
    • A good place for politics is c/politicaldiscussion
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct and the TOS

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.

Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

Long. Printers are pretty complicated machines, because they have to work with a natural product that shrinks, expands, folds, rolls itself up and sticks to other pieces of paper. I once heard a printer engineer explain that they use small puffs of air to lift the paper, but because there's also heat involved in the printing process that the paper sometimes rolls itself up or expands which causes jams etc. And I'm sure there's more going on.

Which isn't to say that HP aren't bastards.

If we shoot for a much more primitive printer, we’re pretty close.

Something that uses a pen or quill to draw on an unmoving sheet of paper. Kind of like how CNC routers are set up. The gantry moves along the full length and width of the paper.

After that, you can print everything outside the electronics and the quill. Right?

That's just a plotter. Replace the extruder nozzle with a pen and you're there.

Paper shrinks and expands? What?

[–] [email protected] 20 points 1 year ago (1 children)

Everything shrinks and expands as you heat/cool it. It's called physics and it's a fucking mess. The more you learn the weirder it gets 😵‍💫

[–] [email protected] 2 points 1 year ago

God damn physics some much for the immaculate plan. Why did god invent physics anyway?

not until the existence of 4D printer, that can print a 3D printer

[–] [email protected] 8 points 1 year ago (3 children)

But wouldn't that mean that you already have a 3d printer that can print a 2d printer? As the 4th "D" is time?

[–] [email protected] 15 points 1 year ago (4 children)

The fourth D is right beside you, even if you can’t see it. It penetrates you everywhere.

[–] [email protected] 8 points 1 year ago

The D was inside you the whole time.

That's why your organs leak out from your ana and kata

[–] robdor 2 points 1 year ago

Oh wow I must be an expert in 5D then, 6D on special occasions.

[–] [email protected] 1 points 1 year ago

It penetrates you everywhere.

Kinky.

There are actually a bunch of theoretical spatial dimensions, including 4th. Check out the HYPERCUBE!

Holy shit dude that is absolutely unhinged, very glad I saw it. I'll never be the same

Schizophrenia on display.

Imma 4th deez nuts down ur throat!

[–] [email protected] 16 points 1 year ago

You can already 3d print a plotter, which is close.

Likely not for a long time.

3D printers aren't a magic make anything tool. They are a versatile and useful addition to our toolboxes.

You could likely print a lot of the parts now. Unfortunately, it would be the "vitamins" that would catch you out. Circuit boards are possible, but difficult. Silicon chips are currently impossible. Print heads would be almost impossible to print too.

Instead, I would expect someone to come up with a more general "auto fabricator". A combination of tools combined with robotics, and a standard set of "vitamin" components. Such a system is perfectly feasible (though not that soon) and could go from raw materials to a functional 2D printer. It could also make a kitchen blender, a new lamp, or whatever you decided you wanted (within reason).

An interesting take is the book series of the bobbyiverse, starting with "We are legion, we are bob". They play around with the limits of 3D printing, and how to go beyond them.

Tl;Dr 3D printers are awesome, but not a "do everything" tool.

*Silicon. Silicone is a kind of rubber.

[–] [email protected] 1 points 1 year ago

Damn autocorrect ducking up my messages. Thanks for the heads up.

[–] [email protected] 4 points 1 year ago* (last edited 1 year ago)

It is possible right now. OP didn't say an electrical printer, it is 100% doable on old mechanical printing model.

[–] [email protected] 3 points 1 year ago

Inkjet print heads are MEMS, so the answer would be until we can 3D print those.

[–] [email protected] 2 points 1 year ago* (last edited 1 year ago)

You can start here: https://hackaday.io/project/176931-hp-printer-cartridge-control-module/details

HP printers are conceptually quite simple devices, the printer just moves the cartridge and the paper. The cartridge does all the actual printing. So you reverse engineer the pinout on the cartridge and you can make your 3d printer do normal printing. That's also how those little handheld cube printers work.

We are not too far from self-replicating machines controlled by AI. They will be built with a simple purpose: find resources and replicate.

Imagine a world with people trying to eliminate such machines, while machines learn new ways to get around any restrictions.

Ah the Hartz-Timor Swarm.

[–] [email protected] 5 points 1 year ago

I was thinking of paperclips.

[–] [email protected] 2 points 1 year ago

What do you mean by not too far? Because I can see A LOT of issues which cannot be solved easily. Even with maximum wishful thinking and a lot of handwaving that's not something that's possible even by a long shot.

Or do you mean not too far, like within the next 1000 years? Cause yeah I could believe that.

Also AI doesn't mean general intelligence, so not intelligence like human intelligence. Don't be fooled by the PR and hype going around, LLMs aren't general intelligence.
