4.3 Swatch – Festive Sensor


Kyle Shoesmith – 3177832


Analog Sensor

For my swatch, I decided to expand upon the analog sensor that I created and create a hat that activated based off of pressure. Originally, I wanted to create a propeller hat that activated through a sensor. However, I ended up not being able to get a hold of the materials that I would have needed to not only make it, but to also create it compactly (Adafruit, Conductive Thread, Conductive Fabric, DC Motor). I then decided to account for that by using a hat that was much larger in size so I could store all of the larger components within them: a Santa hat! This hat is able to light up like a Christmas tree whenever you press the sensor on the forehead.

I first attempted to recreate the sensor from before, albeit more compact in order to fit in the hat better.


I then attached the LED bulbs I had to the top of the hat and used copper wire and M/F wires to connect them all. NOTE: Apparently, my copper wire from before wasn’t working because it had a plastic coating on it that I never noticed, so I used sandpaper to shave off the layers on the edges.


I then went and sewed the Arduino Uno into the hat and accounted the length of the hat by adding wire extenders.


Afterwards, I sewed the patch onto the front of the hat and connected the wires and resistors with alligator clips and copper wire.


What’s nice about the hat is that due to its surface, you aren’t able to see the thread appear on the front, so it looks like a completely normal hat at face value.


Afterwards I quickly wrote the code up and Voila! I’m generally happy with the design of the hat and the fact that I was able to make it with the limited supplies at my disposal. I can’t wait to get a hold of better supplies in the future so that I can explore more in the future.

Materials used:

  • Arduino Uno
  • M/M and M/F wires
  • Copper wire
  • Santa Hat
  • LED Bulbs
  • Velostat
  • Felt
  • Thread
  • Jumper Wire
  • Resistors
  • fritzing

 Basic pressure sensor  and the advanced pressure sensor 

  • Description:

This pressure conductive switch is a simple pressure sensor that has been installed into the cotton fabric. The reason I create this piece is I would like to see what will happened if I use this material combine with another materials. Such as while I’m using the pressure sensitive materials, the interaction between two different materials will creates a unique feeling while you press the pressure material button. Although this is very simple to make, I’m also feel very happy to see the result. By the way, the combination of this simple sensor add with another advanced sensor material can make this looks much better.  The reason I made two sensors is because the material I received was too late, I don’t have enough time to make it better, and also I though the first basic pressure sensor is not satisfied for me.    

Materials for the basic pressure sensor 

  • Cotton sheet with different colours: orange, blue, green etc. 
  • Copper wire, conductive wire, cotton wire and cut copper pieces Arduino, circuit playground, wires, sub port. 

Tools & Techniques: List or describe all tools and techniques used to produce the swatch.  


The advanced pressure is made of: 

  • Cotton fabric 
  • Sewing 
  • Pressure material sheet
  • Conductive sheet 
  • Wire
  • plastic tape

The tools I used for both basic and advanced sensors are:  

  • a scissor to cut cotton sheets
  • needles for attaching cotton sheets and wires
  • A laptop for powering up LEDs and copper wire speakers; Arduino coding software to control the Arduino
  • Tools and materials:

Generative Art Final

Artist Statement

This piece was created out of my love for 3D pens, VR, and filters. I wanted people to have the ability to create art wherever they are. I felt that AR, Augmented Reality, was the most apt solution to this. This is due to the wide range of devices that can support AR applications or files. One famous example of this are the filters that we so frequently use on our phones. This entire project would not have been possible without the help and guidance of my friends who pointed me to the necessary resources to make this project possible.

4.3 Capacitive Touch Control Neopixel Jacket

Video: https://youtu.be/4uVq600y3D0

Materials: conductive tape, Paper or non conductive fabric, Conductive fabric, copper pins, Jumper cables, 5V LED neopixel strip, old jacket, 9v Battery


Description: It’s more like a prototype than a swatch, jacket with capacitive touch sensors on the sleeves, touching the capacitive sensors would change the pattern on the LED strip, perfect for Techno events or concerts. Battery connectivity gets loose so for the future I would make sure to have a proper connector for batteries. Would have loved to use Ida fruit instead of Arduino which would have made it more lightweight and more suited for being a proper wearable.

I had made a capacitive touch wheel for assignment 4.2, I used the same technique to create 3 touchpads using conductive fabric and copper wire.
I brought and 3 pin 5V LED strip and used the adafruit neopixel library for the code
connect the capacitive sensor to the analog-in while the LED goes in 5V,GND and pin.
Sew the LED strip into the jacket, attach the conductive touchpads into the sleeves

Circuit Diagram:


I actually am really Interested in using conductive fabrics. I want to do something with it in fashion. I thought of a brand name too called 3021 Cosmic Couture. I wanted to make something cyberpunk. I was also inspired by the actuator ‘Fibre Optic Poetry’ on KOBAKANT(Link:https://www.kobakant.at/DIY/?p=7031)


The main tools were the home made capacitive sensor using conductive fabric(https://www.kobakant.at/DIY/?p=6607)and the neopixel strip.

I used the adafruit neopixel library for Programming the neopixel strips. It makes controlling neopixels very easy.

  • Swatch Name: DC Motor
  • Feature Image (set this in the righthand column)
  • Group number and names of all Team Members: Group 9, Marquessa, Aimee, Emily, Michael
  • Swatch Type: Actuator
  • Description: For my swatch, I decided to make a DC Motor that is almost entirely 3D Printed.  The motor was made by wrapping magnet wire around a motor core and placing it in a housing.  I did have some issues with the final product that will be addressed in the final foot notes.
  • Materials: PLA, 20 Gauge Magnet Wire, Slices of Aluminum Can, Rare earth magnet
  • Tools & Techniques: 3D Printer, Fusion 360(3D modeling software), soldering iron and wrapping magnet wire
  • 3-5 other images or animated gifs that could include:
  • 1 minute (or less) video that shows the Swatch in use: https://ocadu.techsmithrelay.com/jyPc
  • References/Inspiration: https://www.youtube.com/watch?v=0p2QTE26VOA
  • Additional Notes: When making the motor, I went through 3 different motor core designs before settling on the one that I used for the final model.  The core of the motor works perfectly and can be used as an electromagnet as is shown in the video posted.  However, I did have issues with finding a material that was able to provide power to the core and keep it rotating in the housing.  I tried various materials such as steel wool, aluminum cans, string with tinfoil wrapped around it and pulled tight along the length of the bottom of the core, but I couldn’t find one that would actually work properly.  I believe that if I had some kind of springy steel that would press into the motor core where it is fed power hard enough to keep the motor core in place and the power continuously flowing, but not hard enough to stop the rotation, then that would be ideal, but I could not find any such material in my home or at stores I went to.  Overall, I did have a lot of fun with this project and am going to keep at it in my free time because I think that it would be very cool to get it working properly!

This sad looking Frankenstein cat was meant to be a slightly scarier version of a pin cushion. Since starting this section of Atelier I have re-found my passion for sewing. Because I enjoy more absurd things, I wanted to create sort of a Frankenstein cat in which pins of electricity give it life. Depending on where you would strike a needle through the cat one of its three eyes would light up. Not only would it be an adorable addition to my sewing kit, but it could have also been a fun game of Russian roulette the first time around, before memorising the positions. It is a mix media piece that was inspired by two separate projects I have attempted throughout my trials within this medium.

Creating the Swatch


  • Felting wool
  • Two different thicknesses of string
  • Felt (black and yellow)
  • Stuffing
  • Conductive thread
  • Conductive fabric
  • Thin steel wire
  • 3 coloured LEDs
  • 9V Block battery

outline of circuit

image_2020-12-12_015954As you put a needle through one of the CPs onto the Felt layer the circuit of the specific LED will connect to the ground thus turning on that specific LED.

creating swatch


Here you can see a couple of the steps outlined before the final product.

  1. First the plush base must be made where a sphere is made and stuffed. On top of this sphere the rest of the swatch will be built.
  2. After completing the sphere the conductive fabric should be sewn on it. Remember to leave a slab of fabric hanging since this will be connected to the “ground” of the LEDs
  3. Cover up the conductive fabric with felt in order to make sure the next bits of conductive fabric will not directly connect to it.
  4. Using a felting needle create a small sphere which will serve as the head of the cat and a good place to stab the LEDs in.
    1. IMPORTANT!!! I made a mistake here, a better strategy to approach this would be connecting the head to the ground of the LEDs so, I recommend having the centre of the head filled with conductive material that goes through the body to the ground. This will not only stabilise the body but it will also not tangle the wires or result in unwanted overlaps.
  5. Proceed to connect individual legs of the LEDs to different patches of conductive tape as shown in the picture. Do this with conductive thread. Leave dangling bits at the bottom in order for it to be easier to connect them to a battery.
  6. After completing these and setting the + and – sides of the LEDs focus on customising your Frankenstein cat or dubious creature and enjoy a little voodoo creature you can poke and trigger.

further notes

Unfortunately as it can be seen in the video, the sensor did not work as well as I would have hoped. I had received materials like conductive thread very late and rushed my wiring in order to complete this sensor by today. Unfortunately my initial design technique and approach were not efficient so, likely, a lot of my LED wires got tangled and resulted in them not even turning on. Only one LED remained powerful enough to shine through thankfully allowing me tho demonstrate the potential of this sensor.

Overall I am proud of my creation, I think it turned out good at least design wise having both the obscurity as well as the cuteness desired. I would have really liked to have been able to fix my circuit. I had tested it prior to adding the LED and I was certain it will work until I reached the head. In the future, in order to fix this error, I will make the centre of the head a grounded piece and make sure I connect the base for all LEDs prior to connecting them individually. In addition I will also have a thicker layer in between the ground conductive piece and the separate ones on top. This will provide the space I need to comfortably stitch conductive thread without fearing that it will touch the lower layer. While there were many errors in my design this offered me the opportunity to understand how I can incorporate a  small battery in my creation and also understand better how to take advantage of my materials.

Unfortunately now it is merely a regular yet eccentric pin cushion, I hope I will be able to create this piece again and potentially add an additional pressure sensor to it that would make some sound or keep track of the needles added.

4.3 Crafting Swatches: Analog Sensor – LDR/LED Glove Sensor

Materials: LED Light (Blue), Ldr Sensor, Wiring, Alligator clips, Resistors (10kΩ, 220kΩ), Leather Glove.

Tools: Scissors, Sewing Needle. Electrical Tape.


A wearable glove that activates an LED when there is not a light source provided on the ldr sensor). I decided to use a basic work glove for testing. I extended the wiring with extensions provided by the arduino kit and used alligator clips on the led to ensure the connectivity would still be intact.  The swatch is usable under the context of visibility for the wearer if they are in a lightless environment. In my opinion, if the light source was a bright LED with a higher voltage, or a modified LED with a 3v lithium battery, it would be very applicable for wearers who are in outdoor environments such as camping in the woods (using the light to help guide through terrain or assistance with building a tent).


  1. Create a circuit with the arduino kit and breadboard. The circuit I used was from this link (https://create.arduino.cc/projecthub/tarantula3/using-an-ldr-sensor-with-arduino-807b1c ) . Test for connectivity.screen-shot-2020-12-09-at-6-13-36-pm


2. Pierce the glove with holes for proper application of the LDR sensor and LED.



3. Insert LDR and LED and connect through appropriate wiring.


4. Test Swatch.

Arduino Code/Circuit Diagram



Influence: Speaker actuator/Neoprene Sensor

sp img_3496



Influence:I used the design of both the neoprene sensor and and the fabric speaker actuator for this assignment, due to learning about the circuitry of amplifying the fabric speaker and applying the circuitry in a completely analog format with the use of fabric (in this case leather instead of neoprene).

Tools/Technique:  I conducted more online research to find an analog process that would activate with pressure but instead came across a Light Dependent Resistor (LDR), which is an analog sensor that detects any light source. I figured that with closing the hand for activation it would be a more creative process of activating the LED switch. I found a code and circuit diagram that uses the LDR sensor to activate a LED when there is no light present and tested the circuit. I then punctured holes in the glove and placed the wiring into the glove. I checked beforehand to make sure the circuitry was functioning and applied extra wiring for the user to wear the glove for testing and the end result as you can see  was a success.

Belt Accessory: Night Walk

Watch Video of Finished Work (56 Seconds)
Swatch Type: Digital Switch

Since it is a final project of Experiment four, so I wanted to create a better version of the textile and technique compare to the last assignment; I was focused on the design and creating polished work because I wanted to do more than making the workable sensor. The final piece is a hand-made product with hand sewing technique.

Belt Accessory: Night Walk, is a wearable belt that purposely made for jogging at the night time, but I also care on the asset and cloth design.  My idea started with the thought of the danger of jogging during night time because there could be an accident since it is dark outside. I thought it would be wonderful to create Digital switches for Lilypad LEDs that work in different situations; the first situation is when people are wearing cloth, and the second situation is when people hit by somewhere. Lighting up the led will help passenger and driver to recognize you, and soft push button switch will let you and others identify your danger because it will turn on when you hit by somewhere or lying down. I created pleats on the cloth so I can diffuse the LED by using a backlighting technique.

Additional Note:

What is Working?

  • Hand Sewing; I was able to create a polish work with hand sewing.
  • All the switches
  • Circuits; Getting familiar with materials: conductive thread and copper tape, helped me to create a complicated circuit diagram. Making circuit got much more challenging than last time because of the pleat design of the cloth.

What is not Working?

  • Stability of Battery holder.
  • Creating Robust Circuit; I used Copper tape and conductive thread. However, I learned that making a circuit with conductive thread is much stronger than using mainly copper tape. However, the Copper tape is a convenience to users.
  • Placement of the soft push button; Originally, soft push button was to warn or notify the danger to themselves or passenger by making the LEDs to turn on when the user hit by somewhere. However, based on the experiment, since conductive fabrics size are too small, so the button would not working unless you hit the specific spot. Moreover, When I fall on the ground, other people cannot see the LED because my body covers LED. Therefore, if I am creating this project again, I will create shoulder strap, and attach the led on there, so LED can emit its light when the user falls on the ground during the emergency.

Tip* Putting copper tape on the joint part of the circuit with conductive thread can make a more robust circuit.

4.3 Crafting Electronic Swatches

By: Sana Yasamani 3180650, Serena Seow 3167001, Khrystyna Gandabura 3178285,

Swatch #1:

Sana Yasamani Khiabani, 3180650s, Swatch: The Light-Up Pathways

I further improved upon a sensor I did previously for this swatch, for I truly did want to try out more things in regards to LEDs. It mainly is a Capacitive Sensor. 

Essentially what this Swatch does, is that it is a series of tinfoil, felt, wool, and wires, all connected in different pathways and branches, to have the end result of lighting up an LED. There are different areas to do it, whether within the wool or upon the tinfoil, but at the end as long as two of the wires connect to the conductive sectors, the LED shall light up. 

It’s incredibly layered, with a base part of tinfoil connecting to the LED, a mid part of felt,  an upper part of tinfoil branching around to connect to everywhere the branches are placed, and a final layer of felt at the top, with wool in the places necessary. 

The techniques and tools used shall be represented within the materials section, but overall the most important part is to have tape when things get messy, in order to stay organized. 

Inspired by: https://arduinogetstarted.com/tutorials/arduino-button-led




  • Felt
  • Tinfoil
  • Conductive Wool
  • An LED
  • 4 MtoM wires
  • Arduino UNO


Process Part 1: Half tinfoil, felt, and wires ready. Place all layers beside each other properly. 

Process Part 2: Place the Felt layer, and then the Wire connector layer above the LED layer. 

Process Part 3: Place the final Felt layer with the woolen layer.

Touch Lamp is a mini lamp I created working from my original touch sensor, using the human touch as a capacitor. I decided to use a mini paper origami ball to act as the lamp cover, to give it a softer glow, as opposed to the hard white LED, and used copper tape to fit it all onto a sheet of paper.

Swatch #3,

Khrystyna Gandabura, 3178285, Swatch: Cotton Cloud

For this project, I wanted to experiment with different kinds of fabrics; Taking 4.2 to completion I wanted to experiment with the lights and shading that cotton would create. How can a fabrics and electronics interact within each other.

To create this cloud I used the push button with and LED lights. Created a code, that when the button switch is pressed colours in the cloud change. As well as I added some magnets that hold the light in place. After all the wires with LED are coded I shaped a cloud out of cotton and placed the lights into the cloud; as well as hid all the extra wires under the box.

Heart push sensor


Group 14  Christina Chen
Swatch type  Digital switch
Description  This is a digital switch that works through pushing the heart. There is a sponge on the inside with a hole through it. There is a layer of conductive copper tape on both sides. So when the heart is pressed, the copper tape gets closer together.

Needle and thread, copper tape, fabric, scissors and/or knife, sponge

Tools and techniques
Building off of 4.2 where I made analog fabric pressure sensors, I decided to try something similar where pressure is applied. I saw a digital switch soft push button using foam which looked like it would produce better results when it came to applying pressure. So first I tried this method with a scrap of knit material to see how it would react. (https://vimeo.com/488800742

When it came to actually putting the heart together, first I cut out the heart shaped fabrics with a knife. I laid out copper tape on the inside. Then I used the knife to make the sponge thinner, and scissors to cut the sponge into a shape that would fit inside the fabric. Next I poked a hole inside the sponge with a knife, making sure the hole would be in an area above the copper tape area. Then I sewed the heart together using needle and thread.

The sponge needed to be significantly smaller than the size of the fabric because it needed to be sewed together with breathing room. If it is put together too tightly the switch will not work.

Video  https://ocadu.techsmithrelay.com/cuUD
Reference  https://www.instructables.com/Three-Fabric-Buttons/ 

Notes  This switch differs from the original because the original is meant to be three push buttons. I used the concept of pushing however the materials are slightly different as well. For one, the original uses neoprene while I used cotton. I also substituted conductive fabric for copper tape and foam for sponge. Also the shape is different and my sewing skills are significantly worse.
