PROJECT DESCRIPTION

The concept emphasizes the aesthetics of a fashion accessory, in this case a small purse, which is handy to carry a phone and a wallet. I put attention on the size, colour combination, material, and design. Other design component was sending a message about caring for our planet, a message that appeals to us in our role as guardians of our dear earth, to be more conscious, accountable, and respectful of our natural environment. A phrase made of letters which were built with 3 mm LED lights. “Because there is no planet B” is placed outside at the front of the purse, lights will be activated by the sound pressure level. Sound pressure level is the result of the pressure variations in the air achieved by the sound waves, and it depends not only on intensity of a sound, but also on the distance to sound source.

The message will be displayed in five lines of text that will turn on in sequence line by line, one at a time. The message is activated by sound to a certain level to a certain distance, the level used to activate lights is the one produced by a person saying “hello” at a distance of around two meters. Once lights are activated, lights will turn on line by line and fade off once all lines are on. This process will be repeated five times until, and during this time the sound sensor is not read. Lights can be activated again once the process is completed and lights are off. The idea behind is that when two people meet and salute each other the message will go on, this could be a nice way to start a conversation about our environment.

This purse could be used anytime, it could be casual or more dressy, depending on how it is accessorized. Brightness of lights is good enough to be seen during daytime.

This purse could be appealing to an environment-friendly person who wants to disseminate this type of message and possibly to anybody. This concept is based on:

Material: this purse is made of alpaca, a natural fibre I am familiar with. I have used this fibre to make scarves, hoods, and sweaters; but this time I am expanding and experimenting by making a purse.

Uniqueness: this purse is easy to make. It requires basic needle skills that most people can do. This is a unique piece that could be made and customized to anyone’s taste.

Convenient: the size has enough space to place a cellphone and a wallet. Although sizes could vary according to personal preferences.

Allied with sustainability and ethics: as a designer, I am trying to select a fibre and/or fabric that is made following ethical protocols, which means a fair treatment of the animal and a fair treatment of the people that produces the material. In this case, it is an artisanal alpaca fibre made in a Peruvian Andean community. This was a hand-made item.

I am conscious and concerned of the side effects of tech wearables on sustainability, in this case using LED lights in my project. As Gurova (2020) states, there may be a negative impact on the environment, such as an increase in energy consumption by using electronics and an increase of e-waste from abandoned devices. On the other side, Gurova concludes that the side effect of tech wearables on sustainability need to be further explored, because wearable is a broad technology and they could have different life cycle processes.

Sustainability is also a very complex concept, especially when the world is changing so fast, and many innovations are arriving that we could not even imagine few years ago. For Fletcher and Grose (2012, p.10), changes in the sustainability process in fashion come more from individual actions than from an international declaration. For example, I agree that being accountable or responsible is a more powerful approach than being sustainable, because it seems more achievable something that depends on us that something that depends on someone else. The message for me is to develop and use electronic wearables in a careful and responsible manner.

PROJECT CONTEXT

Regarding my inspiration sending messages using letters and lights I was inspired by neo-conceptual artist Jenny Holzner (Kemp, 2015, p. 219-220). Her work focused on delivery of words and ideas in public spaces, she used LED as a media to express her writing and political opinion.

I also was inspired by the phrase “Because There is no Planet B” that belongs to an organization of the same name (https://becausetheresnoplanetb.com/) that inspires people to look after our planet. I think this phrase maybe be overused, but I think it is still interesting to use it in my project because it is a short statement that fits on this purse size and it is powerful.

Another inspiration was how to build letters made of 3mm LED lights. I found a YouTube tutorial DIY How to make led letters, that was very handy and help me build letters for this project. During this term, when I worked on my projects I tried not to use the soldering iron, because I had never used it before and hesitated to use it, but in this project I used it a lot.

I was looking for similar projects for inspiration, [see reference], I found handbags with interior lights that activated when the handbag was opened to help user to find items inside the bag. I could not find something similar to what I have in mind.

I found a project that I liked very much after almost completing this project. It was “The Sessile Handbag” by Grace Kim (Hartman, p. 449). After my final critique-presentation I wanted to add interactivity to my project. I was checking different resources and I found a beautiful handbag project in Hartman’s book. I appreciated the artist mix of technology, LED lights in natural shapes, where lights fade on and off, creating a subtle effect. This project is similar in some way to my idea of natural shapes, handmade purse and using LED lights. The difference is in the reason to use light, in my case mine is sending a message.

The next handbag I will talk about is a waterproof backpack, maybe related to my work in the sense that through an LED screen animations, custom images and text are sent. My project sends one message, a bright environmental message activated by sound pressure through an interactive sensor built-in on the board I am using [Circuit Playground Express]. This backpack has a different concept, it is more to stand out from the crowd and lights go on when connected to power. It seems there is not interactive sensor, besides it appeals to school and travel wearers with room space to carry a laptop.

After delivering my prototype for this final assignment, a project called my attention. It was the TagURIt (Pailes-Friedman, 2016, p. 078), an electronic game of tag that works with proximity sensors. I wanted to add this type of sensor to this project, but I did not have enough time to order it. The idea was that when someone was close to the purse, LED lights will go on. Instead of that, I used sound pressure level, which is affected not only by the strength of a sound but also by its proximity. It was not exactly a proximity sensor, but somehow could detects when a person gets close and say something, a greeting or something else. The tone of the voice can not be that of a whisper, but more a normal tone of voice to a distance of around two metres.

Circuit Diagram

Outside of the handbag:

All letters in a line are connected to a positive (in red), which will be connected to a “pin” in the Circuit Playground Express. All the negatives (in black) will go to a single line that will be connected to a negative “pin” in the Circuit Playground Express board.

Inside of the handbag:

There will be five “pins” in the Circuit Playground Express board for light switches (in red). All negatives (in black) go to a GND “pin”.

Process

The process started building the circuit and making the letters. LED lights were welded to make letters and then letters were stitched on the purse to make words and lines. Letters on each line were connected using conductive thread and steel fibre

The message is going to have five lines made of welded LED lights and lines will light up in sequence starting from the top. Each line will have its own switch and the code will manage time for each switch, so lights turn on in sequence (the first line will go on firsts and the next line few milliseconds later, and so on). Once lights in all lines are on, they will fade down until they go off and the process will start again.

CHALLENGES & SUCCESSES

The most challenging task for me was to use the iron soldering tool to create letters of 3 mm LED’s lights. I used old CDs to make letter patterns. I built 23 letters, each letter has in average 10 LED’s lights, here my husband gave a hand with the soldering.

img_3701-2

The other challenge was the connectivity. I sewed the letters to the purse and connected them with conductive thread to form words. Unfortunately, the connection was weak. Next, I added on top steel fibre, to make the connectivity more stable and stronger. I found my third line “is no” did not light up, besides the intensity of lights were not even and in some cases blinked.

img_4799-2

The next step was to connect the letters soldering them to build words.

img_5012

img_5018

It was a great idea because the connectivity improved, it was not loose anymore, and the intensity of the light was stronger and visible during daytime, exactly what the guest speaker suggested after my final prototype presentation in class. I was concerned about having some wires showing in the outside of the purse, which would not look nice, but it was exactly the opposite. The words connected properly and the arrangement looked like jewellery. See below.

img_5026

I realized that maybe my project did not have interactivity. The interaction I thought of was a manual switch to activate the LED lights, but that was too old fashioned. I thought initially in using a proximity sensor to activate light cycles when a person was close to the purse. Unfortunately, I was using Adafruit’s Circuit Playground Express and this card did not have a proximity sensor on board. Finally, I found the Circuit Playground Express had a built-in microphone with a library that was able to measure sound pressure level. I decided to use the sound pressure level as a digital switch, to activate lights when values went over certain level. To find the level that would be the threshold value for the switch, I used the sound pressure level example that ships with Adafruit’s Circuit Playground Express library and the serial plotter tool in Arduino’s IDE to figure out a value generated by the voice of a person to a distance of around two meters. This value allowed me to develop a switch that was neutral to background noise.

 

NEXT STEPS

I am very happy with the outcome of this project, although there is always room to improve. For example, the connectivity is good, looks nice and the intensity of the light when activated is great, but I am concerned that placing this letter blocks on top of the purse could tangle with a wool sweater, especially a person is wearing a wool sweater that matches the handbag. In the end, I think there are fashion accessories for each occasion, same as shoes for each occasion, there are purses for each occasion. This project could be extended to different items: a canvas bag, a backpack, a top, jacket, there are many possibilities.

E-Textile Alpaca Weaving by Hortensia

cover-assign-55

In this project, I am trying to explore electronic textiles with alpaca fibre through weaving. From the class resources provided to us, I am interested in creating a textile circuit board, which for me is a to do task, I will try to do on coming project. In this assignment, I will present an e-textile prototype that I weaved with a little embroidery on top.

Prototype Development

Below the sketch of the weaving sample.

img_2168

I did a loose simple weaving using two alpaca color wool: beige and light gray, I used a broken branch as a “loom”.

img_8472

I embroidered a flower button in yellow and for the receptacle I used Peruvian natural cotton. I tried to find some nice colour combinations.

img_8576

Below it is the final piece, the idea was to try to see how to create an e-textile using alpaca. I do not want lights compete with the weave, my goal is to enhance the beauty of the weave with the light. Later I could use this approach and weave lights in an outfit, like an alpaca poncho for example.

img_8509

I used three set of white fairy lights and weaved them with the wool, I did this because the fairy light cord colour matched the alpaca wool color, light gray, in colour and size.

Small LED’s did not compete with the weave on the flower button and the tone of the yellow LED lights matched quite nicely. I would have preferred using Lilypad LED’s, because they are sewable and easier to use, but I did not like the look, they covered the embroidered part that I wanted to show. The option was to use simple LED lights, that fitted inside the embroidered flower button that matched the textile texture. When weaving the fairy light sets, I left the flower lights on before removing the batteries, that helped me guide the distance between lights (see below).

img_2155

img_2100

There are two fade effects, one going from high to low and the other from low to high. Two sets of fairy LED lights have one effect and the other the reverse effect.

img_2162

img_2107

Each led light on the button flower has an individual connection positive and negative because I wanted to turn them on and off in a sequence, as you could appreciate on the picture below and the YouTube video.

img_2154

img_2159

img_2228

I am happy with the e-textile outcome. It would be interesting to try it on an outfit like a poncho or cape. Although I did not try on alpaca fabric, I think this type of lights will work well too.

My reflection about this project are, I found I need to improve how to connect the LED lights to the circuit. It was a little hard to connect the ten LED lights individually to the circuit, in a small space like the button flower. My idea is to use a printed circuit using conductive paint on a piece of neoprene, having the lights installed before the whole piece is sewed behind the back of the flower, having LED lights legs long enough so they can go through small holes in the weave.

Incorporating fairy lights into the weave went smoothly. Additionally, the color of the string matched the colour of the weave, light gray, and the size and colour of the lights was a good complement to the weave piece.

It was interesting to get started with e-textiles. I feel I still have a lot to learn and this is a field I would like to explore. I watched the links and resources provided to us in the course web site, the ones that called my attention were the E-Textile specifically the “Experimental Weaving” at the Unstable Design Lab, University of Colorado. I also liked the “Handwoven White Led Display and Hand Embroidered” at Studio subTela and the “Dear Data Project”.

I enjoyed the key speaker Laura Devendorf at the Symposium for Computational Fabrication 2019 (“Fabricating (Smart) Textiles – Computational Design, Craft, and Radical Possibility”). It was very inspiring to me. She uses design as a mean to critique design and does research on how technology shapes relationship to the world around us, more specifically how fabrication shapes our relationship with material. Super interesting.

Prototype 4: Materials as Sensors

Weight-Sensitive Canvas Bag


Key Image

img_1260


Description

I embroidered this tote bag using alpaca yarn, my favourite fibre.

img_1803

bolsa

In this project the canvas bag lights sewed at the front of the canvas bag indicate the weight being carried inside the bag. There is a scale of lights depending on the weight placed inside. The first light turns on to indicate there is something in the bag, the second light will turn on when more weight is added, and the third light indicates the maximum weight has been reached.

Sensor was made with two layers of aluminum foil separated by a layer of velostat. I glued aluminum foil to velostat in the four corners on each side and covered this with a sleeve made of non-conductive fabric. Sensor’s input goes through pin A2 and output to LED lights goes through pins A1, A3 and A7.

The sensor is placed at the bottom of the canvas bag, so when some weight is placed on the bag and a person lifts it, LED lights will go on depending on the weight of the bag.

How-To

wa4_step01 Step 1
Cut a piece of velostat and two pieces of aluminum foil. Fold aluminum foil to match the size of the velostat, leaving a narrow tip out for connectors.
wa4_step02 Step 2
Aluminum foil was glued to each side of the velostat in the four corners, so glue does interfere with flow of electricity between the two layers of aluminum foil.
wa4_step04 Step 3
Sensor is covered with non-conductive fabric to isolate the sensor and avoid short circuits. Fabric is thick, so it provides some cushion too. Fabric is stitched on the sides to make a sleeve that will cover the sensor.
wa4_step03 Step 4
Next is to fix the Circuit Playground Express and connect LED lights. I used both conductive and non-conductive thread.
wa4_step05 Step 5
The Circuit Playground Express board is stitched at the top of the bag using non-conductive thread.

My LED Basket Handbag

proto3-cover

My Prototype 3: Digital Switches for Embodied Interactions My LED Basket Bag

I decided to use a basket bag to experiment the prototype of three switchers which are activated through the use of LEDs. There are two body environment switches such when someone hold the basket bag handles and fairy lights become activated, and when the bag is opened a switch located at the bottom of the bag activate LEDs place inside the bag. The other category I can call clothing gesture because the bag has a button that helps to lock up safely through a loop, then when bag is close with the loop LED’s light are activate by a switch
img_0871

Circuit Diagram

We have three circuits for the digital switches –red, blue and yellow, each of them representing a set of lights, the yellow representing a set of fairy lights– and three circuits to power the LED lights. Pins D2, D3 and D4 are used for the digital switches and ports D11, D12 and D13 are used to power the LED lights. Of course, this diagram is a simplified version, because the wiring inside the handbag depended on space and positions of switches and LED lights (we use sets of light for every switch and the wiring had to satisfy these requirements).
prototype3

Here detailed hand made diagram of the wiring for each switch.
handdiagram

Arduino Source Code
Code can be found in GitHub (see here).

Description

A. Handle: Body/Environmental Switch

When a person holds the handbag by the handle, the handle will be illuminated with a strip of fairy lights. When the user releases the handle, the light will go off.
The switch was made using copper adhesive tape, which is wired to an board mounted on a using flexible wire. To make the bridge I used copper tape and a red cloth where I adhered the tape and when I hold the handle with this cloth the bridge activated the circuit and switch then lights were on. The Arduino card and all the connection were place inside the basket bag.

Discussion

Overall, all the switches worked well, although there are some reflections which are applicable to all three switches because they use similar materials and have similar connectivity. First, I do not like the connections are so visible, I would like to something more subtle, but I am still learning and prefer to be more comfortable with connections that the appearance for now, but this look bother me
About the wiring and switches can be further refined, copper tape is easy to manipulate plus its flexibility helped me to attach to a surface such the basket which is hard but not enough to keep stick in place, sometimes the tape didn’t stick well and if I moved the basket so much the connectivity could get lost and stop working, maybe using conductive fabric could be a better option.
Another point perhaps is the use of a full-size breadboard and the Arduino Nano 33 IOT
This bord is large and with the battery connected are heavy to place inside the bag. Maybe using the Adafruit’s Circuit Playground Express would have been better, but I think using the Arduino Nano to make this prototype is probably fine, but it is good I can realize about what I like and what I do not like to make better choices for my final work.

B. Button Up: Clothing/Gestures Switch

The handbag is “locked” with a loop and a button. When a person closes and locks the handbag by placing the loop around the button, two LEDs at the centre exterior surface of the handbag will go on. When a person opens the handbag by releasing the loop around the button, the exterior light will go off. The connections were using copper tape and stranded wire cover with silicone because was very thin and flexible. The switch was located along the loop then when the bag was button up the contact between the button and loop activated the switch and LEDs were on.

img_0989

img_0992

Discussion

These reflections are almost the same I stated above on the handle switch, all the switchers used similar materials and have similar connections. First, I do not like the connections are so visible, I would have preferred something more subtle, but I am still learning and prefer to be more comfortable with connections than the appearance for now, but the look still bothers me.
About the wiring and switches, they can be further refined. Copper tape is easy to manipulate and its flexibility helped when attaching to the basket surface. However, the continuous movement of the bag caused the tape to move and, in some cases, detach from the basket surface, which caused loose connectivity. Again, definitely using conductive fabric could be a better option.
Another point perhaps is the use of a full-size breadboard and the Arduino Nano 33 IOT. That plus the battery was large and heavy to place inside the bag. Maybe using Adafruit’s Circuit Playground Express would have been a better alternative. I also need to do more research about the wireless options available in the Arduino Nano, which may help reduce some wiring. I am happy with the outcome, but not so much with the visible connections.
In terms of usability, I think it would be better to reverse this switch. The idea is that if a handbag is unattended and somebody opens it, a LED light will go on as some kind of alert. I would also like to add a sound, but that required to a speaker to the configuration which I still do not have. Another option would be to send a message to a device (a phone), but that would require an application listening.

Material used in this prototype

Breadboard
Adhesive copper tape

I use practically the same material for all the three switches, but here instead of fairy light I used LEDs

C. LED’s Inside Basket Bag: Clothing Gestures

When a person opens the handbag, a set of lights will go on to illuminate the interior of the handbag. When the handbag is closed, the set of lights inside will go off.
It is always handy to have light inside a handbag if the owner is looking for something inside. The circuit in this prototype was build in a similar way than the other two switchers. Here the switch is placed at the bottom of the handbag, then when the handbag opens the upper and bottom part of the handbag activates the switcher. The copper tape makes contact and LEDs go on.

img_0988

img_0950

Discussion

Overall, the switch worked well, similar reflections that I made for the previous prototypes applied here too. There is also room for improvement, my big take here is to use conductive fabric and a smaller board like Adafruit’s Circuit Playground Express.

LED Heart Alpaca Bracelet by Hortensia Reyes

LED Heart Alpaca Bracelet by Hortensia

Description

I love alpaca fibre, is soft, light, breathable and hypoallergenic. I weaved this bracelet while trying to learn how to weave. I love textile jewelry because wearing them are very comfortable, I made a necklace of alpaca fibre too.

img_0575

Now I tried to incorporated lights to this bracelet to see how it looks.

In this project I used fairy light strip and shaped as a heart, I sewed these light on top with regular thread of the bracelet. The “heart” lights fade following a heartbeat and inside the “heart” there are three groups of blinking sewable LED lights. The LED lights blink at three different rates: slow, medium and fast blinking. The piece represents a beating, sparkling heart –a sign of love– and lighting is applied on top of an alpaca bracelet but I sewed these lights under the bracelet, then light come through the textile, I want to have a subtle light, not so intense. I like how the light were show all together.

The fairy light strip and each group of LED lights have its own connection to the Arduino Nano 33 IoT board. Each connection uses a different port on the Arduino board for the positive, that way the program can apply the corresponding effects and blinking or fading rates. The Arduino code combines the fading and blinking basic examples, but uses proportional refresh rates for fading and blinking, since multiples delays did not produce the desired effect (delays accumulate and fading and blinking became all too slow).

The piece is quite light, around 100g, which meets the weight wearability criteria for the wrist by Clint Zeagler’s video (Zeagler, 2018), which specifies under 0.5lb for this part of the body.

Since I started testing the circuits using the Arduino Nano 33 IoT, I learnt the final result did not meet the portability criteria to be strictly wearable. Perhaps the Arduino Nano 33 IoT was not the best board selection, because it has been designed to be used on a breadboard or a socket, not precisely a sewable board. I know the Adafruit’s “Circuit Playground Express” would have been a much better option, since it does not have pins and it has holes that can be used to be sewed on a piece of fabric. This board could have been powered with two 3V coin batteries, which would have been enough for low power lights like the ones I used, and this would have met the portability criteria for wearability. The most important for me doing this prototype was learnt how to do the connectivity, build circuits and try to use the Nano 33 IOT which I never used in my life.

Circuit Diagram

Below the circuit diagram. As you can see, there are three sets of LED lights inside the heart, this was made with the fairy light strip. Each set of LED lights as well as the fairy light strip have their own red wire (positive), which connects to a different port in the Arduino board, that way they can get different effects each.

Each red wire line does not touch each other, also red and black wires do not touch. We are using a USB portable charger showed on the diagram below to power this project, but for this project to be wearable we would probably have to use a set of coin batteries.

Context

“Light-up LED Cuff / Bracelet With Magnetic Switch (e-textile)” (Dawson, 2017)
When I started with this project, I tried to find simple guidelines to understand how to connect and sew conductive thread to integrate into my textile (weaving). I found this helpful website, easy to follow and with clear directions, maybe too easy to understand because it was a project for primary school students, but it was good for my first prototype. I watched the video tutorial that help me on doing my sewing with the conductive thread. I recommend this to anybody who is pretty new on e-wearability.

“Making a Face Mask with ANIMATIONS!!” (Nedforge, 2020)
This was the design that inspired me for this project. Although I did not do a face mask and did not use the LED Matrix, which was built with individual addressable LED strips, this was an interesting project. I did not know the LED Matrix and the supporting software existed. On the down side, welding was required for this project and I do not have a soldering iron yet. The idea of light animation inspired me to use sewable lights in my bracelet. Maybe in my next project I could use a LED Matrix to create more light animations.
“Actualizer: LED Bracelets” (Actua Canada, 2016)
This was the terrible animation, because although was a simple project like the the first example “Light -Up Led Cuff” the explanation was not clear, the video helps but the explanation was unclear, the design was very sloppy and there is not a list of the material needed to make this project. I think is because the first example was address to school students the demonstration, video, photos and list of materials was clear like a lesson for students in the classroom which could be used for a school teacher to do this project in class.
