Shout-outs to David Rios, Addison and Yony for helping!

Unofficial final presentation of our audio project during our ICM class, we invited classmates to try our "sound installation” piece.

Unofficial final presentation of our audio project during our ICM class, we invited classmates to try our "sound installation” piece.

For this project, we pursued something that was more hands-on and closer to a physical computing class project. Viewers are invited to squish the colorful silicon objects, which will play a sound on the connected laptop.

The components of this project include: 8 unique shapes made of silicon, with 8 force sensitive sensors attached, each wire wrapped to connect to a longer wire in order to connect to the breadboard, a borrowed and overdue Arduino nano, and a laptop running the P5 code that will play the sounds (also one red LED light for my sanity, which you can see next to the Nano in the video below).

Making the Silicon Shapes

We had a lot of help from Addison, who taught Effy, who in turn taught me the secrets of mixing silicon.

For our silicon shapes we used silicon graded 00-30 on the Shore hardness scale, which gave the bounce we wanted when pressed down on lightly.

Step 1: Mixing the silicon

To make the silicon mix, it comes in two bottles labelled Part A and Part B. The ratio for the mix is 50:50. For our small circle shape, we used about 12 grams each, for a total of 24 grams.

Step 2: Adding color

To dye the silicon to the desired color, only a little bit of dye is necessary. Mix well!

Effy had sorted out all the colors first in Illustrator. For the color palette of this project, we went with less saturated, pastel colors.

Step 3: Vacuum chamber

After the mixing is complete, place it into the vacuum chamber, adjust the valves, and watch carefully for the silicon mix to start bubbling. Once the bubbles subside, then it’s ready to be poured.
