It's not just the weird contrived queries getting worse-than-useless artificial "intelligence" summaries. One of my kids just did a google search for something they actually wanted to find, and got AI nonsense. This "oh it's only contrived queries" line from Google doesn't convince me. There's a lot of ambiguity in normal speech, and fine judgment of ambiguity is not the strong suit of an LLM.

Nothing says "this is a reputable company to do business with" like several paragraphs of lorem ipsum on the front page. /s

mcdanlj,
@mcdanlj@social.makerforums.info avatar

@xarvos @kaia Well, the first paragraph is from immediately before "[do]lorem ipsum" in Cicero's De finibus dolorum et malorum from which lorem ipsum was borrowed, and the second is a later sentence from which some of the garbage text of lorem ipsum was borrowed. So you could say it's not exactly lorem ipsum. 😀 But despite the brilliant loose translation here provided, I do suspect that in practice it was intended as placeholder text.

Designed and some aquarium hose couplers because I refuse to pay €20 for a little chunk of plastic. There is no way this can go wrong right? Right? 😂

@andy_warb This is where the machining hobby comes in handy. I've made quite a few barbed fittings from aluminum on the lathe. 😀

My local bike shop guy heard about my quixotic quest to adapt a 40 spoke Sturmey Archer hub to a 36 spoke rim with machined adapter plates, and give me another hub to play with.

It looked nice on the outside, but it did not make the expected ratcheting sound that a freewheeling hub should make when spun. It also did not work correctly.

I thought maybe it would just be full of gummed up grease inside so I poured a bunch of paint thinner in there and let it sit, but that did not fix it, so I disassembled it and found it to be extremely crusty, rusty, and gunky inside.

I'm going to try to make it work again, even though this hub still won't work on my bike because it's drilled for 28 spokes lol. It just seems fun to see if I can clean it up and fix it.

@zackstern @MLE_online Do be aware what metal you use it on, though. Joe Pie recently did a video showing what evapo-rust can do to high-carbon steel, and the stains on my cast iron mill table from a few inadvertent drops long ago are persistent.

mcdanlj,
@mcdanlj@social.makerforums.info avatar

@zackstern @MLE_online The problem is called carbon migration or carbon surfacing. Here's the video:

The evapo-rust FAQ describes this:

@zackstern @MLE_online Fully submerge it, and pull it out to check every half hour to an hour. If you see a dark film, wipe it off while it is still wet.

If you partially submerge a part, it will remove oxide to bare metal at the air interface, where it will the readily oxidize again, and then the chelating agent will again strip the rust, and so on; it is a form of electrochemical etching I guess...

@zackstern @MLE_online Yeah, me too! Fortunately when I did that it wasn't a precision part. 😅

As I caught myself considering whether to manufacture 1:3 scale tubular cam locks for smol computer panels I decided that my 12yo self would be confused but happy about how this phase of my life unfolded.

I told my friend the other day that I feel a bit post-singularity in the sense that ~three years ago I left a straight-forward career and at the same time the world went sideways so I have ~no ability to predict what will happen even next year.

Surprisingly, I'm mostly OK with it. 🤷

mcdanlj,
@mcdanlj@social.makerforums.info avatar

@trevorflowers That's an interesting engineering challenge... Instead of trying to scale everything equally, you could do 1-3 pins that are larger than ⅓ size. I'd think that trying to make springs for roughly 1mm wide pins could be one of the real challenges of a 1:3 scale tubular lock...

My partner has put over 800 miles on her new plug in hybrid, and she still has over half of the original tank of gas from the dealership.

PHEVs are seriously the best of both worlds if you're not ready to take the leap to a fully electric vehicle.

mcdanlj,
@mcdanlj@social.makerforums.info avatar

@kwf @phpete Also, modern gas is much more stable than gas from 50 years ago, I've read.

mcdanlj,
@mcdanlj@social.makerforums.info avatar

@kwf Other that the clogged EGR valve/cooler combo endemic to the series, our Gen2 Chevy Volt has been wonderful. I think we're closing in on 170K miles, and much of our driving is electric. It's not as efficient as it once was, so as it ages, the percentage of gas miles has gone up over electric miles. We used to get about 50 electric miles before switching to gas; now it's more like 35.

Sadly, nothing shipping today has the electric range that the Volt had when we bought it. ☹

1.0 is being prepared! Integrated workbench, and a lot, lot more... https://yorik.uncreated.net/blog/2024-007-freecad-news-21

@yorik This part in particular intrigued me:

The renaming and the conversion table system offer new possibilities: It's now possible to not only use default names like Edge4 or Face6, but also custom names like TopFace. Although this is not yet used by FreeCAD tools, it offers very interesting possibilities, where subcomponents could be referenced not by their order in a list, but by more meaningful characteristics. This might lead to very interesting developments in the future.

Right now, as far as I know, semantic toplogical naming has been the province of CadQuery, which, though very interesting, is explicitly code-based. Bringing semantic topological naming to would be awesome!

mcdanlj,
@mcdanlj@social.makerforums.info avatar

@yorik Imagine if you selected the face with the Z-most centroid, and then replaced it with a vertical hexagonal prism or even with a dodecahedron, the design intent would carry through!

I could imagine an example workflow where you select a face to sketch on, and if the face matches any of the semantic topological names at that point in the workflow (e.g. top-most, left-most, rear-most...) in the sketch you have a checkbox (or radio buttons including "none", I guess, if the names are defined such that more than one semantic name is possible) to attach the sketch semantically.

I'd imagine the same selection options for the entry panels for Part Design operations like "pad" and "pocket" alongside existing options.

Of course, I'd imagine those names would also show up in the general attachment editor.

Just musing aloud. I imagine more experience with the TNP mitigation in place will show more where this would be convenient.

mcdanlj,
@mcdanlj@social.makerforums.info avatar

@yorik So many amazing possibilities!

I could imagine a some-modifier-select bringing up a context menu in which you choose what of all possible semantics you desire to express the intent of your selection. 🤔

Just one of these schematics is correct. Can you see why?

So I've got this empty concrete pad on the side of my house.

It used to have a rotted out 12x24' shed on it, but I demolished that last fall and figured I could do something better... 🧵

@kwf I bought a Bosch 8 amp proper SDS+ hammer drill and it made a world of difference. It cost the same as two days of renting it...

mcdanlj,
@mcdanlj@social.makerforums.info avatar

@kwf Here's another unexpected benefit: I needed to drive nails overhead, up into old, dried treated lumber. I couldn't manage to do it swinging a hammer. I put an impact socket into the Bosch, put it over the nail heads in hammer-but-don't-twist mode, and drove those nails in about 2 seconds flat.

I don't use it much, but when I need it, it sure comes in clutch.
