MachinePix Weekly #11

A full-size Gundam mecha, and an evolutionary biology explanation for why they don't really make sense

Some last minute changes and a postponement of this weeks interview, but Ill have something exciting for you next week

The most popular post last week was a full-scale Gundam model at a Japanese amusement park. As always, the entire weeks breakdown is below the interview.

Im always looking for interesting people to interview, have anyone in mind?


The Week in Review

Prosthetic makeup and masks use several discrete parts, usually made of latex foam, to allow a range of movement and expressions. This was a motion test and you can see the commercial results here.

The Singapore LRT website lists this feature as smart glass, which isnt very helpful. A follower pointed out that its likely Polymer Dispersed Liquid Crystal (PDLC) glass, one of the two ways to implement switchable glass (featured in another popular @MachinePix post).

I learned that the fountains these balls are installed in have a technical name, Kugel Fountains, and then I was disappointed to learn that kugel is just German for ball. Fun fact: these balls do not float (they are denser than water)they are supported by hydroplaning.

A great example of a very scoped, very useful implementation of Augmented Reality. @MachinePix has also posted another, more macabre example.

This weeks most popular post. Huge mechas dont really make sense on Earth because they run into the same challenge as huge animals: mass increases cubically as muscle power (or hydraulic power in the case of a mech) increases by a factor of two. This is kind of like a biological analog of the Tyranny of the Rocket Equation. At some size, the support structure is too heavy for to move.

That said, who caresI want to see the Gundam.


Ive been practicing with the CNC embroidery machine, and its a more complicated than I would have thought. Partially because working with compliant material like textiles is challenging, and partially because the tools to digitally define patterns are not well maintained. Curiously, Linus Torvaldscreator of Linuxis the author of an open source embroidery machine file converter.
