Ujjayi Layer

dsc07906

Ujjayi breathing is a breathing technique employed in a variety of Taoist and Yoga practices. In relation to Yoga, it is sometimes called “the ocean breath”. Typically translated as “victorious breath”. Ujjayi Pranayama is a balancing and calming breath which increases oxygenation and builds internal body heat.

Using a stretch sensor along the bottom of the rig cage to acquire breathing information, lines of lights are activated as the wearer breaths, deeper breaths activate lights further down the chain.  This is a melding of body as display and body sensing assignments into a version 2 of both.

Here the display is taken into the realm of self monitoring of ones own breath as a source of meditation, encouraging long deep breathing or Ujjayi breath.

The Happiness Tube, has been adapted and updated to work with a stretch sensor, and now uses the Lilypad instead of the Arduino Leonardo. The piece is now made from a Duvet Cover and Satin with soft pocket for neopixel battery pack. The inside functional layer combines the stretch sensor belt into an inner shirt that contains all wiring through conductive thread.

VJ GLASSES

Being a VJ I always thing that during my VJ jobs no one actually looks on VJ what is the good way to attract more people so that people can see apart from a DJ there is a DJ too which is also playing an important role in creating an immersive environment within audiovisual art. So I decided to design some gear for myself as identity gear where I will be wearing that gear as an icon or as a trademark or for a remembrance. So I chose to design a VJ glasses.

VJ glasses are one of its kind sound reactive led glasses which is based on the idea of a sound equalizer the way how sound equalizer react according to music. So I decide to create sound responsive equalizer with the help of neopixle led ring

INITIAL DESIGN:

Initial design is based on a plastic based normal sun glasses I bought it from cheap market where I uses led neopixle on its  and mic

Reasoning / Why remake?

I chose this project for a few reasons. Firstly, it was fun! Although it’s somewhat tacky and not something I would wear, it’s nice to have the tactile sensation of something small I can hold in my hands. It’s also something that I felt I could realistically do — something that my skill sets were suited to and would yield good results. Finally, I was never satisfied with the original, yet the idea had stayed with me ever since the first brainstorming exercise. I continue to think about it even today, and would like to eventually make some kind of produced multiple out of it. That continued interest made it seem like an ideal project to continue.

 

 

Wearability

Pendants are obviously quite easy to wear — simply add a string or chain and place around neck. Although the second iteration aligns more strongly with the original goal, I perceive it as less wearable than the original. This is because the original was cheating in a sense: the string was actually wire, and the battery back was in a pocket, leaving only the LED to be housed in the pendant. The second iteration features the battery and all connections embedded within the assembly, requiring it to be quite big. While it’s fun and works well, I can’t really imagine anybody wearing it except for possibly young girls. An important question was raised in critique, about if I had considered my target market but I admit I’ve done little market research / thought little about industry. However, I did get excited earlier in the semester, and purchased the domain name www.blingalingaling.com

Perhaps I can produce some silly low end jewelry for kids, or the strange adults who celebrate the aesthetic. Japan? Comic Con?

 

 

 

Material Choice / Design Influence

The initial goal for the second iteration was intended as a dramatic shift, changing the name (“Pears”), using twin reed switches (a great suggestion from Professor Hartman), and including audio + NeoPixels. I purchased a number of supplies to attempt this goal, but ended up struggling to find a design that could house all components and deliver enough voltage for the piezo buzzer. Given the limited time I decided to stay close to the original project, and therefore stayed with a 3D print / LED based project.

The pink PLA plastic was chosen somewhat randomly, as were the blue LEDs which had recently showed up in an Ali Express order I had placed. The aesthetic took little from consciously from external sources, except for image searches of ‘hearts’ and ‘pears’. The design influence owes much to those providing tutorials online for Fusion 360, as it was only watching those videos that gave me the skills to produce the models.

 

 

Changes 

Changes were drastic and include a complete redesign of the circuit and enclosure. Whereas the original featured a single 10mm LED, v2 includes 26 blue 5mm LEDs. The second iteration also sees a switch to a LIPO battery (yay, green!). The most important change (despite increasing the form factor) is the new functionality of the two items ‘completing’ each other to produce a result, whereas the original was more of a simulation. This sees the original conceptual fulfilled.

Evaluation of Prototype

As noted earlier, the second iteration became less functional as a day to day wearable — largely due to the significant increase in size. It’s also somewhat tacky and isn’t something many people would likely want to wear. Despite these realities, I’m quite happy with the prototype, and see it as showing much promise as a proof of concept. Anecdotally, fellow students have been delighted with the simple mechanism, and I’ve been proud to show it faculty, friends and peers. Advice given in critique about possibly avoiding representation (heart / pears) in future iterations was well noted, and I plan to follow through on the advice.

On the next version(s) I will put aside representation, focus on reducing size (through surface mount components / manufacturing) and enhanced functionality (more interesting interaction / possibly audio).

Laser Hat 2.0

 

“Eye damage from a pocket laser is unlikely, but could be possible under certain conditions. Red laser pointers that are “properly labeled” in the 3-5 mW range have not caused eye damage — no retinal damage has been reported — but there are very real concerns. One is pointers not manufactured to federal specifications. There are reports that green lasers, improperly imported to the U.S., far exceed safety limits.”

I am remaking experiment 4: Body As Display. The old one I made has a ring switch, I loved the concept but I found that it does not work well as the way I wanted it to be: the fabric in the hat keeps getting in the way and made the controlling of the system very difficult. For the experiment 6: wear your own, I didn’t change the concept the hat, the only thing I changed is the way of the switch, from a very physical switch to a digital and wireless switch; the Bluetooth on phone switch. Nowadays people have everything on their phones, and I think making the switch on the phone could make it more fun, and it could be something people can actually use in their everyday life.

Some Inspirations

My criteria for wearability was to be small, light weight, good looking, not too expensive, and ideally only works well when it is a wearable, and can not easily be replaced by a normal object.

It preforms well for wearability. It is easy to hide everything inside and in pockets because it is a hat and it has a lot of hidden spaces. I wore it for couple hours, and the problems I encountered were firstly the Arduino chip was a bit of heavy; secondly the laser pointer got off from the desired position. Other than these I think the hat serves well as it’s purpose.

I did not change anything about material choice and design influence.

Signal | Bike Alarm and Sign Indicator

Even though Toronto can be considered quite adapted for bikes, commuting surrounded by cars can be quite challenging. Both of us commute everyday to school, and we believe that one of the hardest thing for bikers is to signalize to cars which direction we are heading to. As part of one of our assignments at OCAD we decided to develop a display system that would help us alert the cars around us of our actions.

FIRST ITERATION

We are on different levels of biking, I have been biking for a while not but Leon has just started biking, for him it is really hard to bike without both hands on the handle, so we came up with a solution that uses an accelerometer to detect your head movement to trigger different states of the display that indicates which way you’re going to.

If head is straight it will show blue light, indicating you’re going forward. If you lean forward it turns red indicating you’re about to stop. If turn your head either left or right the light turns green to the side your head is turning too.

img_7036img_7035img_7039img_7038

 

Even though this solution helps beginners as it doesn’t need you to move your hand to click a button or switch for example, it is not very practical. During some early testing we realized that turning your head around is a very common action when you’re biking so sometimes the lights would trigger even though we were just biking straight. The other downside is that moving your head while you’re turning or even stoping can diminish your vision. So we decided to improve it.

 

SECOND ITERATION

For our second iteration we decided to use two buttons as triggers, one for left and one for right and if you want to stop, you just need to press both. Instead of attaching the display to the head, Signal is now part of the bike frame. We also decided to use LED strips for this iteration as it is much clear to indicate direction with it.

To create the case we used acrylic and wood to make a box that sits perfectly on the rear rack of the bike. The LED strip goes around the outside of the box, the acrylic is used to cover it and dime the light. All the electronics are inside of the box.

ALARM

Another huge problem that every biker faces is the increasing numbers of bike thefts. To solve that issue we used the same PCB, wiring and accelerometer from the previous iteration and added a speaker. We wrote a code detect shaking and trigger the alarm. If the alarm goes off in order to deactivate the biker need to press a sequence code using the two buttons on the front. After deactivated Signal goes into biking mode which you can use to sign your directions.

Hot & Cold is a notification device in a form of a headband that is triggered according to the surrounding temperature. The hairband includes a temperature sensor and a Neopixel LED that colors vary from dark blue to bright red according to the surrounding temperature.

Hot & Cold was what we decided to work on remaking from the first prototype of “SMARTER THAN ME” which was a piece of accessory in the form of a ring bracelet that also used a Neopixel LED in exactly the same way to show a range of colors depending on the temperature.

We are both into fashion and wanted to explore designing a piece that met our criteria in order for us to be able to wear it on fancy occasions.

Looking at our common interests, aesthetics played a big part in what we personally thought would make a valuable piece of accessory.

We also wanted it to be lightweight, comfortable, and contained.

Materials Used:

Felt
Thread
Wire Flower Petals
Velcro
Buttons
Arduino Micro
Coin Cell Batteries
Coin Cell Battery Holders
Prototype Board
Wires
Silicon Wires
Temperature Sensor
Neo Pixel LED
Electric Tape

We redesigned it in the form of a headband because we thought it was interesting to experiment with as a headpiece that we wanted to be able to wear in the future.

In the above left picture showing the prototype of “SMARTER THAN ME”, the ring was extended in a braided chain that acted as a bracelet and also connected to the breadboard which holds the Arduino, sensor, and portable power supply.

Similarly, in the “HOT AND COLD” headband the flower which is the newer version of the ring is also extended with a braided chain that is connected to the prototype board which holds the rest of the components needed for it to work.

HOW IT’S MADE?

We hooked up all the wiring that was needed on to the prototype board and securely soldered it on.

We then connected 2 coin cell batteries to the prototype board in series in order for us to add the Voltage so we can have a sum of 6V.

We then contained everything in a pouch that we stitched using grey felt and thread.
The silicon wires that connected the Neo Pixel to the prototype came out through the edge of the pouch.

We covered them again by braiding three colored threads over the wires.

We chose silicon wires because they are flexible and light and can resist any bends better than other types of wires.

We attached Pink, Blue wired petals around the Neo Pixel that created our flower which was the main visual part of our accessory.

We chose Blue, Red, and Grey as our color scheme. Blue and red are to represent the warm and cool colors that we used to appear in the Neo Pixel. We decided to use grey as a complementary color that would blend in.

The reason we chose wired flowers was to be able to position them in any way on our hair and close the flower if we wanted to dim the light.

On the pouch we cut out a square of the felt that exposed the batteries for easily exchanging them later if they wear out. We covered that area with a piece of felt and attached it using velcro for easy access.

This whole pouch went into a black cotton head band. Again, the flower and extended silicon wire were left out to attach to our hair using bobby pins.

We secured the pouch inside the head band with black buttons.

Below are videos showing how we braided the silicon wires.

 

We are very proud of the piece that we think is beautiful, unique and meets our criteria.

We actually planned out a way that we could both share it so that we can both enjoy wearing it at occasions that were special to us. In the future we plan on making more for our loved ones as gifts!

Heartthrob Ring

Accessories and jewelry is an integral part of human décor. It’s been an identity cornerstone, a defining factor, something that we treasure and recognize ourselves with. Traditional precious metals such as gold, silver and platinum adorn our day to day lives in many fine ways.

But what makes something precious to us? What is of value to us? What do we treasure?

Concept

As an exploration into the future world of personal accessories, I worked on constructing a ring, that would have personal value to the wearer which is born out of though rather than what it is made of, its monetary value or traditional aesthetics.

I think that all these aspects, namely, aesthetics, monetary value concerned with materials and their use will be challenged in the coming years.

What goes into making something a wearable?

A few questions addressed during the development process were, what interface is easy in a basic wearable, what should it do, how to create value from minimal interaction with a wearable electronic device?

STAGE I

Exploration using a pulse sensor (input) and LED (output)

For this accessory, I used the pulse sensor as input and LED as output.

A few questions that were addressed during this process were. How personal or intimate are body bio indications (i.e. heart rate, pulse rate, breathing patterns)? Can these be shared with friends and family? What do they convey?

The initial idea was a design for a couple band , where the pulse rate of the wearer was sent through a Adafruit Feather HUZZAH ESP8266 to the Huzzah set in their partners ring. This would trigger the LEDs in the ring and make them blink to the pulse rate of their partner.

adafruit_products_2821_iso_demo_01_ORIG.jpg

The initial exploration with hardware was very basic and was meant to evolve the idea from paper to physical working components, this was done using a Arduino UNO, Pulse sensor and LEDs/Neo Pixels setup.

Arduino UNO + Pulse sensor + LEDs/Neo Pixels

The pulse sensor was set up using an Arduino UNO board the output was in the form of two LEDs. One LED was set to blink to the pulse reading of the sensor and the other was set to fade. This gave a lasting hue to the light produced within the ring.

Product Design

Two designs were explored for the ring product. The first was a two LED set where the LEDs were wrapped and shaped with the help of masking tape. The second was a single Neo Pixel ring where the electrodes were made of brass wire and were an extension of the ring band, the connecting wires were soldered on to the brass electrodes.

In the case of the Neo Pixel, a separate library had to be added to the code.

STAGE II

During this stage, all the hardware was made hands free. The electronic components were taped to the wrist. The pulse sensor was attached to the back of the Arduino UNO board, this was then strapped to the wrist with tape. The placement of the pulse sensor on the wrist at a certain position was a critical factor for it to function properly.

A pack of 3*1.5V battery pack was used power this system. The battery pack was also taped to the wrist.

STAGE III

At Stage II, the hardware and electronics components were large in size. To reduce the size of the components, the board used at Stage III was the Arduino Lilipad. This is a relatively flat slim and small board often used with textile wearables.

The adjustable wrist strap that was constructed out of Neoprene fabric, where all the electronic components were embedded.

The power source for this wearable version is a 3.7V LiPo battery.

The visual impact of the LEDs in the ring were toned down, so that they were only viewable by the wearer mostly or someone standing in close proximity to the wearer.
