Project Concept

After seeing Clement's very cool presentation, we started looking into Kirigami patterns and noticed that many of them include a book fold.

Template and instructions for this model can be found here:https://ullagami.com/how-to.php

Since this type of design includes and open/closed or on/off state, it seemed like it would be fairly straightforward to turn one into a switch or even use the Kirigami model as a switch/lamp combo where the lamp would be off when closed and on when opened.

Project Process

We started by making one of Ullagami's simple templates to understand the basics of how these models work.

Then we looked at our lamp example and made a template based on that.

While it was satisfying to be able to approximately replicate a design, we didn't love the results. It looked too simple and uniform. Taking a cue from Frank Lloyd Wright's elegant sense of proportion, we made some adjustments on a new template and model.

Questions for Jb and Daniel: Since motion will be involved in operating this project, is is possible to capture the kinetic energy of each fold and use that to power a light source? Even if it was just for a second, that would be pretty cool. Would size make a difference? Could we get more power if the model was quite large, 6' x 3' for example? Update: Exploring a self powering light is not going to be possible in this workshop, however, here are a couple of interesting examples.

Went in to office hours to learn how to use the Thing Lab's Silhouette Cameo cutting machine. I was hoping that this machine would be able to replicate the things a person can do, but faster and with more accuracy. It may be able to do that, but our first attempts did not produce that result. On the other hand, we discovered that it can easily and quickly do something that would be difficult and slow for a person to do. It can cut very fine shapes with no over cuts.

At this point we could spend out time trying to make the machine do what we originally wanted (same thing we can do only better and faster) or we can explore things we can do with the tiny accurate cuts the machine can do, but we can't. Since there is no explicitly defined outcome for this project, it seems like more fun to experiment with ways to use tons of tiny cuts.

  • Paper folds really well along perforated lines. Perhaps this is a way to make an origami model more flexible and more easily articulated?
  • Multiple parallel cuts allow paper to stretch.
  • Cuts may open up when activated with a bi-layer.
  • What could stippling do that is different than perforation?

Question for Bonnie, Daniel and Jb: Do you know of any papers, resources (or places we may want to look for them) that could help us speed up or thinking about what various types of cutting patterns can achieve?

Brooke succeeded in making a switch out of copper fabric that will turn our light on with capacitive touch.

Our original plan was to activate the lamp by opening and closing it as a hinge, but now that capacitive touch is an option, we'd like to incorporate that into our project. We've decided to connect 4 kirigami models to make a 360 degree structure, and operate it with a series of origami models that change the color of light through capacitive touch.

New template that includes cutting pattern for the exterior edge. Tabs (outlined in blue) will be folded inside to allow 4 models to be connected together. Update: the cutting pattern (blue outlines) is not structurally sound and would cause the model to fall apart. We're opting for using a straight diagonals line along each edge to create an overall diamond shape.

Arduino & Capacitive Touch

Our Project also used capacitive touch as the controller for the lamp. We had three models all made from different materials that were all copper based. The turtle was made from copper mesh, the elephant was made from copper tissue foil, and the lotus was made from copper polyester taffeta.

We also used a neopixel strip for the light source.
