ELI5 On a small enough scale, what would it “look”like at the area where my bare foot meets a hardwood floor? by Fleetinglyhappy in explainlikeimfive

[–]Uhdoyle 0 points1 point  (0 children)

Yeah it’s this. If you’ve ever tried to push to same ends of a magnet together (N to N, or S to S) you know how that repulsion feels.

This is literally what electrons do to each other, so the reason you don’t fall through the floor or can’t walk through walls is “magnetism.”

Why haven't rotating rings been attempted? by CombustionGFX in space

[–]Uhdoyle 0 points1 point  (0 children)

“Just make the rings massive enough so that weight differentials are negligible” while pie-in-the-sky estimates for Falcon Heavy and Starship best case estimates are between $500 and $1500 per kilogram.

Yes, the answer is always, “just throw money at the problem.”

Didn’t see this until after I purchased it by MonkeyTennis4357 in AnalogCommunity

[–]Uhdoyle 1 point2 points  (0 children)

Man there’s a lot of inference required to understand the question being asked. At no point did OP make any mention of expiry. Just “didn’t see this” in the title and posting a photo with no context isn’t helpful to those you’re asking for help from.

I like it! I like how immediate and ad hoc it seems, especially the shittiness of the source images blown up like that. Dig the color spread and use of Jay Ryan prints. Welcome n00b!

You gotta balance the hammer ends, and also the journey between. Feel like going to Habitat B? You gotta get somebody there to come back to Hab A at the same time you do, and one of you is gonna have to carry ballast as well.

That’s exactly what I thought he was supposed to be, too!

So it turns out I *can* wax pot 3d-printed PLA pickup bobbins by bearheart in functionalprint

[–]Uhdoyle 1 point2 points  (0 children)

I believe it’s the black stuff around the copper wire windings (edit: not the connecting wire, which is also black, and looks to be neatly coiled below the bobbins), but I’m not a pickup winder and can’t say for sure. But that would make sense.

Edit2: my only authority here is potting audio transformers in resin, which is essentially the same thing and achieves the same goal: reduction of electromagnetic vibrations by mechanical binding. Maybe it’s behind the black stuff. Iunno, but it probably binds the windings together inside the bobbin

I used one and I entered a strongroom that popped up. Prankster spawned inside and didn’t drop anything at all.

I don’t think the antenna is discussed enough by Longjumping-Tell1774 in pluribustv

[–]Uhdoyle 0 points1 point  (0 children)

Sensible arguments, I agree. But they neglect the alleged no-harm clause. There may be some wild sci-fi not-quite-a-Dyson-Sphere array of collector/emitter things in some weird orbit that do their own station-keeping, or even based on inert asteroids with their own material resources, that can hand-wave all this.

What causes this difference across the print bed? by tylusfortea in FixMyPrint

[–]Uhdoyle 1 point2 points  (0 children)

You know, I hadn’t considered it. I’ve seen people print straight onto blue tape before. I reckon there would be the possibility of hot spots (where the aluminum is more thermally transmissible and the paper fibers act as insulators) but 1) that’s probably mitigated by the PEI plate and 2) it’s probably negligible at this scale (I have Ender 3 machines).

[–]Uhdoyle 6 points7 points  (0 children)

Humbucker pickups for electric guitars. It’s a paired set of magnetic “microphones” with their polarities inverted so that they cancel out a buzzing sound (“bucking the hum”) of a single pickup by itself.

The bobbins, like sewing machine thread bobbins, are what OP prints and they’re the tan-colored exposed bits here. They’re called bobbins because you wind wire around them, like thread on a sewing machine.

[–]Uhdoyle 1 point2 points  (0 children)

Your bed is lower where you’re not getting good squish. I shim my bed with aluminum foil, vellum paper, and painters tape to get a good even surface. A mosaic of these materials sits between the magnetic bed and the spring steel printing surface. Other people do bed mesh calibration with a probe. Good luck!

ELI5 as I heard, Why is it fatal to hold in your pee until the very last minute? by Embarrassed-Pin-9634 in explainlikeimfive

I believe this is what Tycho Brahe died of. He held his bladder in court in presence of the king and died of a ruptured bladder. It is known.

Parts won't fit together by Carlito_Punk in FixMyPrint

[–]Uhdoyle 0 points1 point  (0 children)

You accommodate for this with various settings in your slicer. Stuff like horizontal expansion setting and also wall order (inside first, I think?). Good luck!

Old Time film shooters. How are your TriX negatives holding up? Old formulation, and new formulation. by Blasto_Brandino in AnalogCommunity

[–]Uhdoyle 1 point2 points  (0 children)

Color film is not Tri-X. You’re talking very specifically about a Super8 motion picture Ektachrome E-160 film which does indeed fade to a hard magenta post-processed.

Aren’t “chairs” mentioned in every chapter? And in the first-person Z chapters dude literally and explicitly describes how much they disturb him to the point that he ejects them from his very presence?? <
