Happiness Tube


Great for dancing the night away!!!

Happiness studies show that colour and light contribute to overall happiness, looking at it, playing with it, sharing your happiness display with everyone who sees you, will increase everyone’s happiness!


Colour tweaking Mode:  In this mode the wearer can play with knobs of colour control.

Happiness Colour Wave Mode: In this mode the colours cycle through a perpetual wave of changing rainbow.

In a future version I would swap out the Arduino L for something smaller.




Hearthrob Ring ver1.1

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?


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 portable or a wearable?

The questions addressed were, what interface is easy in a basic portable, what should it do, how to create value from minimal interaction with a wearable electronic device?


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

For this accessory, I used the pulse sensor as input and LED as output. How personal or intimate are body indications (i.e. heart rate, pulse rate, breathing patterns) ?

Can these be shared with friends and family? What do these human biological fingerprints convey?


Arduino UNO + Pulse sensor+LEDs/Neo Pixel

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 shaped 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 seperate library had to be added to the code.

Social Signal

Social Signal
 is a low-tech wearable, that can be manually adjusted to
tell others how receptive one is to conversation. Reading others can often
be hard, and this device takes some of the load off of social interactions.

Red light? They’re busy and you leave them alone.
Yellow light? They can talk, but only if it’s important.
Green light? Good to go! Let’s have a chat about whatever.


The following gallery shows both early conceptual sketches emerging
from an in class brainstorm, as well as both faulty and correct circuits.

This project was very rewarding, in that it was the first time I used
proto-board to make something somewhat finished. Going to Creatron
and collecting parts (like the dip-switch) was something I hadn’t done
in this kind of context, and seeing it all come together was exciting.

One valuable lesson I learned, is to be SURE the circuit is correct before
soldering everything together. I did an initial test and made and assumption,
and ended up having to tear it all apart and resolver everything. (see close up image below)


THE Laser Hat

THE Laser Hat

by Bijun Chen


The laser hat is a hat that can fire laser beam. It is activated by a special resistor ring. The idea came from miner hats, and the laser remotes used for presentations. It could be used as a cool cat toy, or a pointer to presentation, or a Halloween custom.

This video meant to be a gif. It gives an idea of how it works and how powerful it is! Inside the hat, I have a carefully hidden circuit, including a laser moudle, a tiny battery pack, and an open switch which can be turned on and off by the ring. No wire can be seen from outside of the hat, the only thing shows is the front of the laser.


The hat is simple but it has much potentials. It’s the first project I have made that requested by many people telling me “I WANT ONE”! For next generation, I’ll make the on and off switch controlled by Bluetooth over the phone.

Some Reference:


VJ Glasses


I came up with this idea of vj glasses What separates my glasses from the others out there, is that mine use an external mic which make my glasses sound reactive  This project uses cheap and easy to gain parts to allow you to create a one of a kind fancy dress party piece. These glasses do not obstruct your vision any more than the original shutter shades. Even with the glasses on turned on, no glare from the LEDs can be seen as LEDs are on the outer layer.









for this i use neopixel LED Ring which is an addressable ring. i make it animate in a sound reactive way so that when ever it get some sound it create some patterns on it.

Cycle Signals

Marcelo and I both like to cycle quite a bit but in a city like Toronto that can be quite dangerous at times. There’s traffic coming from all directions and the hand signals can be misleading and also for a novice biker like myself hard to actually do.


We instead created a bike helmet that would indicate where we would like to turn as well as when we would be stopping by simply nodding your head in the direction you’d like to turn. We used the NeoPixel ring as our means of communication and an accelerometer mounted on top of a helmet as the input.



Background Research:

According to the Toronto Police, over 500 cyclists were involved in collisions between June and September of this year alone, which is about 4-5 collisions a day.The assumption we do make is that most accidents might happen at night or during low visibility. We wanted to try and understand this problem a bit better and suggest a simple solution. After a bit of digging around, we found a Kickstarter project which is looking into the same problem called “Lumos“.

We created a simple code which uses the NeoPixel library to indicate left and right in green, red for stop and blue for on and we even did a quick test of it outside.

Smarter Than Me

by Sara Gazzaz and Mahsa Karimi

Link to Device One: https://github.com/saragazz/TempRing.git

Link to Device Two: https://github.com/masakarimi/SMARTER-THAN-ME-

Smarter Than Me are two notification devices that are triggered according to specific sensors.
First device is a ring that is attached to a temperature sensor and according to the surrounding temperature it’s colors vary from dark blue to bright red.
Second device is a jewelry attached to winter gloves. This smart device is a notification system which triggers if it enters a previously set location by the wearer.


Device one includes a Neopixel light that is attached to an Arduino and a temperature sensor. Temperature sensor acts as an input and according to the value captured the color of the Neo pixel light changes. The device is coded in such that it maps low temperature to a darker blue light, high temperature to a bright red, and the in-between values are mapped accordingly to different hues of red or blue.

Device two includes a Neopixel ring that is attached to a photon. Connected to IFTTT, if the current location of the device matches the previously set location by the wearer, the Neopixel turns on. Such action works as a notification system.
