Week16 Wildcard

This week I played with folding.

The course Geometric Folding Algorithms: Linkages, Origami, Polyhedra is fun. I was attracted by the folding below and decided to try.

I use vinylcutter to make crease lines, and then fold along them. At first I wanted to make crease lines on both side for mountain and valley, but it was almost mission impossible to adjust the positions. Finally I made both mountain and valley crease lines on single side. It was a bit difficult to fold along the valley crease lines but still doable.

Fold along the crease lines from outter to inner, and the paper will curl as step#2 below. After finished all creases lines, push a part of the circle through the hole then you will get result as step#3.

I tried with different size & different width and got results as below:

No idea why the photos in the course can be so flat, but mine were so curly. Anyway, I like it. I decided to make multiple pieces, wrap them with LED stripes, and put them into a transparent jar, to make the lamp body of my final project.

I will use LED stripes instead of a single LED later. And I want to create the jar by myself.

I did the model design by Fusion360.

I used inspect -> draft analysis to check the model, and found I cannot create it with 1 or 2 pieces, because of the under cutter.

It can be done by 3 pieces, each for 2 surfaces.

I wanted to make the pieces by composites. I use epoxy with net fabric and use a water bottle as the model for prototype.

The result was not good. It was not transparent enough.

In the reginal review, Rico and Ted suggested me to check Justine Testado’s work. Using tape to protect the paper for crease lines, and then brush resin on the paper. It seems great. I will try this to make the composite paper with LEDs in the resin, then fold it, put it into a mold and add more resin. And thus I suppose to have a nice lamp.

I also tried the folding with squares, and found it very interesting, that it has two stable status. So I decided to use it as an on-off switch for lights:

Paper is too fragile, and I tried with plastic sheet from document cover. However, it didn’t work either, as it tended to be flat and can hardly stay foldered.

I might try with thin aluminum sheet later.

Embroidery

This week I also played with embroidery. We use brother SE1800 sewing and embroidery machine.

It was important to make the cloth as tight as a drum in the frame. Otherwise, the thread might get messy and it might even break the needle.

I use the built-in font to make my name tag.

Then I use Turtlestitch to write code for stitch.

The result can be exported as dst file and be used by the Brother embroidery machine.

I created a mobius circle. Not quite sure why it warned too long and will get clamped. I will check and fix this problem later.
