Expressive Wearable: Joyce Yu



The concept I have come up with is the expression of anxiety and feeling overwhelmed caused by loud surrounding noise through an interchangeable circuit, which in this case is a scarf. When I was in high school a few years ago, I encountered many people who had a hard time dealing with stress from loud noises of the environment their in. I also found that they had a hard time expressing this issue and letting people be aware of this problem which is why I wanted to create a wearable that would alert others about the noise volume.


My objective and goal of this assignment was to program the circuit to graph sound when the switch is on. When I first tested it out and experimented with different codes, I found it very interesting how the number of LED lights on the CPX correlated to the sounds of its surroundings. So, I thought that this is a great way to bring light on the impact noise has on someone’s mood in a way that is convenient for the wearer. I have also incorporated pieces of Velcro which makes it simple to take on and off- an important element when looking at the practical factors of wearable technology. I also put a lot of thought into creating something that is interchangeable because certain items of clothing may not be able to be worn annually.

  • CPX
  • Conductive Thread
  • conductive Fabric
  • Needle
  • Thread
  • Felt
  • Mini-USB
  • Velcro
  • Scarf



After coding the circuit to turn on to react to surrounding noise, I transferred the file onto the CPX USB file and tested it out with alligator clips. Then, I threaded conducting thread into a needle and wrapped it around the A3 pin (Power) and sewed it into the felt fabric following the circuit diagram.



Additionally, I cut two small rectangles and two narrow strips of conducting fabric and sewed that onto the top of the CPX with one strip vertically. Then, I followed the same process but with the Ground pin but sewed the last narrow strip vertically so that the two pieces slip into each other and stay put without having to physically keep the circuit closed. After, I took normal thread and sewed it along the other pins to secure the CPX onto the felt. Then, I cut the top portion of the whole circuit, folded it, and sewed it along the bottom where the mini-USB would go through with normal thread.


Finally, I cut the remaining pieces of felt around the circuit once more and placed Velcro around it. The opposite pieces of the Velcro were then pressed onto the circuit and put on the scarf.

Reflection and next step:

Overall, this assignment was very fun and after seeing the end result, I was very satisfied with the outcome because I have never done anything remotely close to coding and working with circuits. In the beginning, I was pretty confused with how to carry out my idea because sometimes troubleshooting did not work but after experimenting many times on the Make Code platform, I was able to successfully make the CPX do what I intended it to do. One thing I hope to do better in the future is getting a better understanding of how to program the circuit into doing more specific things and applying different colours. Finally, I think it looks pretty well put together and I am happy with the idea I came up with because I was able to use past observations to make a wearable that is relevant to many people.
