Exploring other things...

I guess I'll need some more practise in producing videos, there's still some unclear instructions and a couple of hang-ups in it. I still hope for decent light conditions in my improvised video studio to shoot the how-tos for icosahedron and dodecahedron, with the potential to redo the intro part as well. However, this video gives you an impression how fast models can be build: Only seven minutes show what's happening between the first connection and last connections being made, without time lapse.

How to build a tensegrity cube

I started shooting some instruction videos for The Affordable Tensegrity Toolkit, which will be available via Big Cartel as soon as I finished documenting how to build the Platonic Solids with it. There's certainly room for improvement when it comes to the production quality of the videos, but so far I'm quite happy with the result. Contact me via this blog or via lutz (at) smart-at (dot) net for further information.

For real

Last century, it took months if not years to start a shop. In the 21st century, it took me the better part of an afternoon to do so. I admit, part of requirements is a PayPal account, and it might take some days to verify your details to have it fully activated. But then, unless you have a customer base before you start, you don't necessary expect anything happening in the first hours of operation.

Like a spider in its web, I can sit and wait for the first order to arrive per email. Luckily, this means I can spend my time in other ways. Like producing a how-to for The Affordable Tensegrity Toolkit. The free shop at Big Cartel serves as platform to manage internet sales. I have no idea how many random visitors come across, as all interesting features transform the free shop into paid one, a classical freemium business model. That means I will have to bang my own drum, in the shape of youtube videos.

So far, I offer only the models that can easily be mailed, but feel free to use the contact form of the shop if you're interested in something you see here, or to discuss specific projects. For of all you lucky enough to live in Melbourne, you can have a look and a chat when I'm on the Rose Street Artist's Market in Fitzroy.

PS: I mentioned spiders and their web before - Google has picked up the shop and included in its 'tensegrity' alert.

And that's TATT!

Different times have different toys, different ways to explore constructive creativity. Mechano or Lego come to mind to name some of those amazing influences on the development of creative minds around the globe.

Lego provide the 'atomic' toolkit, solid pieces of matter, stacked together. The Affordable Tensegrity Toolkit brings us closer to the unpredictable nature of quantum mechanics. The regular structure come with a twist, or a wobble, a bit of surprise based on very simple rules of construction. You build atoms, which basically consist of plenty of empty space. The empty space and the lightness of 'solid parts of matter' become apparent in a finished tensegrity structure.

Two tetrahedra with opposing chirality

With six struts, you can build the first platonic solid, the tetrahedron.

Trigonal dypyramid 

With nine struts, a structure with surprising properties emerges. Three tensegrity prisms (or tensuls) stacked on each other form the trigonal dypyramid.

Flattened dypiramid

This structure flattens under pressure and bounces back happily.

Trigonal Prism

The trigonal prism offers less excitement, due to lack of symmetry across its corners. It squeezes down, but doesn't bounce back too spectacular.

Cube

The cube can be build in two ways. Above you see a cube where all the corners rotate in the same direction. The faces appear square, yet while lying on a face the vertical struts 'lean' to the side. With mixed chirality, the struts cross each other orthogonally, yet each face looks rectangular.

Two stacked orthogonal cubes

Of course, it takes 24 elements to stack to cubes together.

Octahedron (view onto triangular face)

Yet it just take 12 struts for the third platonic solid, the octahedron. Its symmetry in combination with elastic tendons provides lots of bounce.

Octahedron (corner view)

Pushing the corner towards each other flattens the model.

Cuboctahedron (view on triangular face)

With 24 struts you can build the cuboctahedron, or Vector Equilibrium. This structure shows the transition from cube to octahedron, and has thus six square and eight trigonal faces.

Cuboctahedron (view on square face)

All of that (and things I haven't thought of) can be constructed with a maximum of 24 toolkit elements. The remaining two platonic solids, icosahedron and dodecahedron, require 30 struts. The simple joining methods allows it to put smaller models together (like the two stacked cubes) to create larger ones.
