- paper
- copper tape

Week 10 Assignment
1) Finish your heating circuit
2) Construct at least 2 test heating elements.
3) Measure their resistance, then use Ohm’s law to determine the proper power source. Test them with your thermochromic swatches and heat circuit.
4) Construct a mini-project that reveals an embedded message, pattern, or behavior using thermochromic ink.
Week 9 – Anna Garbier
A trio of vellum speakers
Each speaker in the set includes a copper tape coil and a 10 Ohm resistor on vellum. The coil shapes vary from triangle, to square, to pentagon. All emit intelligible sound.
Click to watch the speaker in action.
A fourth swatch made with a longer coil on .4mm birch plywood needs some debugging (no sound yet).
Week 9 – Zhenyuan Shi
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.
Week 9 – Youchun Zhang
For this week’s speaker assignment, I tried different combinations – conductive tape with cardstock paper, conductive tape with soft paper, and conductive thread with muslin fabric. It took me a while to figure out that I need to use the insulating tape to cover one end of the conductive tape. It was also harder than I thought to keep the tape as close as possible but not to touch each other. But the process was really fun.

Paper Speakers
This week’s assignment consisted in making different swatches of speakers using soft materials. In my case, I used paper and conductive nylon. The test went pretty well and they work great! I also tested drawing shapes using conductive marker, but it didn’t work at all. Conductive marker is slightly unreliable when is used in long and complex shapes.
Materials:
- Paper
- Conductive Nylon

Week 9 – Erica
I chose to use conductive threads and sewing machine with the 3 swatches and picked a fabric that matches with the metallic conductive threads. Sewing the threads close to each other was harder than I thought, but it was good to get some practice.

Here are my 3 speaker swatches:
The first one is made of conductive threads and embroidery cloth. I tried to use sewing thread to fix the conductive material on the cloth. And for the second one, I wanted to use conductive tapes and wood to create a pattern different from the spiral. As for the third one, it is similar to the woven speaker. I wrapped the yarn on the embroidery frame first and then embedded the conductive thread in it.
