For my final, I decided to explore projection mapping, and link it with the soft circuit that I learned in this class.

For future iterations, I want to improve the interface and make it fit better with the paper structure. I also want to make the paper structure into a bigger scale so the installation will be more immersive.

For this week’s assignment, at first I was trying to sew the SMA as a thread to see how it works. But soon it got tangled and started breaking. After that I took the SMA out and sewed it on to a kind of fabric which will have a nice wrap while being pulled. In the beginning I used to much thread to sew the SMA onto the fabric that when it is heated it didn’t have enough space to move. Then I cut out some thread, it started working. I used a pressure sensor which is connected to the analog input on Arduino and mapped the analog output according to that.

For this week’s assignment, since the material we are given are electricity and thermochromic ink, I came up with the idea of creating a project related to global warming to raise awareness of people’s use of electricity.

In order to have a more better graphic quality, I chose to apply ink with screen printing. Here are the illustrations I created for the screen printing process:

During the process, I realized it is very hard to mix thermochromic ink with screenprinting paint. It required a lot of thermochromic pigment to actually mix with the screenprinting paint. Here is the screen-printed illustration that I have:

After that, I created the circuit for it using copper conductive thread and fabric:

When the circuit is connected to electricity, the ice-cube under the penguin will fade away and the penguin will become redder:

For this week’s assignment, I created two fabric speaks and one on vinyl. The two fabric speakers are of the same material. I changed the tightness of the coil to see how the sound will change accordingly.

I build the AT Tiny circuit with conductive thread on fabric.

1. Switch connecting to Arduino:

I used a switch to turn on/off a LED.

2. Sensor for Arduino:

I created a pressure sensor to dim up/down the LED connected.

And here is the code for the sensor:

3. Midterm idea:

For my final project, I want to create a 3D paper bird lamp, so when you pull its tail up, the light would turn on, and then when the tail is down, the light will turn off.

Here is a paper prototype of it without a tail. And here is the design plan for the tail and how it is going to integrate with the circuit:

For this week, I created a node for battery with felt and conductive thread, then I made a node for LED with paper and copper tape.

Then I created three nodes(two kinds), the first two with felt and buttons, then one with wires, paper clip, and conductive fabric.
