Here's a Youtube channel with similar content. https://www.youtube.com/user/thang010146/videos

I found it a while ago while deep in "related" videos, it's one of the few channels I'm subscribed too. As I understand it, he's retired with a doctorate in mechanical engineering, and just likes making little mechanisms in Inventor.

"507 Mechanical Movements"

If it wasn't for the 1800s date after this title, I would have thought it to be a proposal for an additional HTTP status code.

I still search the web by curiosity, turns out 507 already exists for WebDAV, and it means "Insufficient storage".

507: Insufficient storage, mechanical movement of disk required

Sounds like a great catch-all euphemism for human error. AKA the computer received faulty input from the keyboard/mouse movement.

'Layer 8 error' is a good one for that, based off the OSI 7-layer network model.

The date just made me think it would be about watch/clock movements... which is a somewhat closer guess.

This has been here before (not surprisingly) I used it as a way to get better at mechanical CAD, building the movements as models and then trying to animate them. It was quite instructive.

These are beautiful. It's a shame that the underlying drawing library is proprietary, though. Many animations are missing, and I'd love to contribute. Number 36 looks like it would have been fun.

Might be fun to animate one of the escapement gear images and include a pendulum. The tri-bevel-gear assemblies are useful for generating counter-rotating prop assemblies for propellers, drone blades in a gimbal, or ceiling fans by fixing a pair of middle gears to a hollow shaft and driving one of the other two. That's also an interesting mental exercise in topology since initially you're taught c cc c cc c when asked what is the direction of rotation for a particular gear in a series on a flat surface but here you must rotate the surface in mental space and analyze the results to determine direction from an outside perspective.

Yeah it's too bad most of the animations are absent. 5 out of 7 I clicked had no animation.

Start with the thumbnail view. If the thumbnail is in color, it has an animation.

A fascinating book. I have a paper copy published by Watchmaker Publishing and available on Amazon [1]. The drawings in the book are the original edchings, not re-drawn and coloured as on the web site.

It would be awesome if the original drawings could be reincorporated. I imagine once the animations are made, it would take a little additional work to decompose the original image into components that the animator could use. This way, designer/graphic artists (who don't know how to animate) could contribute to this!

Folks whom like this might also be interested in the Ashley Book of Knots (ABoK).

Since it should be public domain, here's a pdf magnet url:

It would be nice to have some toy-set for kids with this.

Or some nice svg templates that can be easily laser-cut...

And/or stl files for 3D printing...

Meccano?

I guess I'm not going to be productive today. stares in fascination

It would be really graet to see this combined with https://www.youtube.com/watch?v=DfznnKUwywQ

This is fantastic. Reminds me of the better part of a morning I spent at the beginning of the summer at the Boston Science Museum, where, in a dark, neglected corner of the basement, they have a very old display with motorized versions of many of these mechanisms. I think I was the only person there the whole time.

There's a lot of buzz about "learn-to-code" movements, but people are generally just as illiterate about mechanics, electronics, and other basic science. I think we may have covered 5% of these mechanisms in one unit of my HS freshman science class.

We do a terrible job teaching science in the US...

I actually don't think that's true.

Sure, our curriculum doesn't cover each of these mechanics. But they do cover the basic properties of levers, pendulums, pulleys, gears, cams, chains/belts, levers, etc. Every single one of these mechanisms is a recombination of those ideas. I would argue that for fields that don't actually require designing or building mechanical objects, an understanding of what the primitives are is enough.

The analogous features in computer science would be things like functions, values, loops, etc, that it's certainly possible to understand without being a good programmer. You can know (at a high level) what sausage is made of, without actually being a sausage-maker.

Maybe I just had some substandard science curriculum. We got pretty much the 10000, or 100000 foot view of most topics.

I think the bigger problem is that US education is so overwhelmingly aligned with teaching to what is on the SAT. There are a hundred basic life skills that are scandalously neglected in favor of pushing everybody up to calculus (ignoring a lot of the geometry and trig that is useful to know if you end up working in trades) and finely tuning our abilities to churn out five paragraph SAT essays. Shop and Home-ec classes have been slashed. Everybody should be able to bake a cake, hem a pair of pants, balance a checkbook, change their oil, replace a lawn-mower belt, understand a loan agreement or lease, hang a shelf, etc.

The title reminds me a lot of the Elektor series of electronics books from the 80s - "301 circuits - practical circuits for the home constructor".

Probably mostly familiar to Europeans....

Elektor, Omni, and Playboy. The last one was a bit repetitive.

(... repetitive? Your Honor, totally unintended.)
