Ease The Pressure by Trish

 

As the pandemic has left us working from home we find the fatigue of sitting on our desks behind our screens all day. For my prototype I have designed a device a to help ease the pressure on ones elbows while they work. I used Expanded Polyethylene also known as EPE Foam because of its flexibility, compressible and shockaborbing properties as the the main part of the prototype. Sandwiched inside the EPE foam is a conductive (aluminum foil) and resistive (velostat) materials to create a pressure sensor that lights up the Adafruit Circuit Playground Express .

Hello: The Social Distance Greetings by Trish

‘Social Distance’ has become the new buzz word of the decade not being able to hug, shake hands or even stand too close. For this prototype I have tried to redefine how people can say hello to each other in interesting ways borrowing ideas from the Black Panther movie and the pandemic greetings.

1.The Wakanda Hello

Description

The Wakanda Hello is a pair of gloves that uses conductive materials to light an LED to signal that someone is gesturing hello. This prototype is a body gesture of one crossing hands on the chest, it has two coins attached to a pair of gym gloves that when they come into contact an LED lights up.

As we have changed the way in which we now say hello due to the pandemic the Wakanda Hello makes for a fun way for people to greet each other. The connection is simple and straightforward and could also be an interesting way to say hello to people even over video calls.

Materials and Parts
Gym Gloves
Double Sided Tape
Alligator Clips
Full Size Breadboard
Arduino Nano 33 IoT
Jumper Wires
LilyPad Tri-Color LED

USB cable
Coins

Discussion

This prototype was quite interesting to work on, some of the challenges I faced was finding materials I could work with but managed to improvise with what I have. As a future iteration I would hope to make the connection less bulky and with less wires which would get tangled up during testing, as well as add different light modes to indicate someone’s mood. Some of the things that worked was the gesture was quite seamless and the idea of using coins as the conductive material was fun to work with.

2.The Elbow Hello

Description

The elbow greeting has become the new normal in an effort to help reduce the spread of the Coronavirus. The Elbow Hello is a prototype I made using a pair of old socks for the stretch material, its worn just below the elbow and has a social switch. I used aluminum foil as the conductive material that lights up an LED when someone’s elbow bumps with someone else to complete the circuit.

Double Sided Tape

Aluminum foil  

Discussion

This prototype was a bit difficult to work with especially when making the prototype it required some improvisation with materials and alot of try and error. The finishing wasn’t very clean but it worked well in terms of interactivity, I would like to further explore a less bulky iteration with no wires hanging loosely.

3.The Mask Hello

Description

For this third prototype I used a mask as it has now become a part of our daily outfits whenever we go outside. The idea for this was to have LEDs create a smiley face at the front of someone’s mask to signal a hello when the LEDs light up. I made a button switch in between the masks lining using felt and aluminum foil so when the two pads of the button come into contact the LEDs light up.

Discussion

Some of the challenges I face in this prototype was figuring out what would be the best connection for the switch, initially I had thought of a contact switch but the design didn’t quite work out when it came to execution. The second challenge I faced especially not having conductive thread was connecting the LEDs but I managed to improvise with a conductive wire. Overall the prototype came out well and it was a great learning experience seeing what worked and what needed to be improved.

Music Festival Headband by Trish

PROJECT DESCRIPTION

During these uncertain times of the pandemic we find ourselves looking back and longing to go out for social gatherings. For my prototype I decided to design a headband that lights up to the beat of the music. Its use is not limited to music festivals can be worn at house parties and other events that involve music.

The music festival headband is a wearable device that is designed to light up the world of the user the idea is to capture the attention of the people that surround the user. The headband has a sound sensor that captures the beats of the music to light up the LEDs insync with the music, when the music is off the headband doesn’t light up.

The device consists of 8 different colour LEDs connected to an arduino nano on a breadboard and also has a  microphone sound sensor module that detects the sound of the music. The wires are wrapped around the frame of the headband and covered with ribbons so as not to be visible. As we are limited to make use of the supplies we have at home I covered up the long hanging wires with black ribbon so as to mimic or give the illusion of someone’s hair as a next iteration I would like to explore less bulky electronics so as to keep the design compact.

Some of the challenges I faced while designing the headband was figuring out how to place the LEDs especially because I didn’t have any conductive thread but eventually improvised with wires. The full sized breadboard was also very bulky so I packed it in my fanny pack so that its not seen for when someone is moving around although it is not a long term solution but for a prototype it worked well. From Clint Zeagler work “Where to wear it” he mentions that a wearable for sensing can be worn on the head.

PROJECT CONTEXT

ORPHE ONE are a pair of shoes that emits lights and sounds in sync with the wearer’s every foot movement whether a step or a jump. Equipped with full-color LED soles and high-precision motion sensor technology, the revolutionary performance of this smart shoes is sure to capture the eye of the audience. The shoes can be linked, customized and controlled using an app. The shoes are interesting because they can literally help someone communicate their feelings without having to say a word.

As my projects is an accessory I’ll mention the Joule it is made as a piece of jewelry.  Joule has a heart rate monitor that helps one to achieve the best result for their workout, by providing the heart rate information while they are working out. It also tracks the calories burnt not only when one is exercising, but also accounts for the missing 90% daily caloric expenditure. Even though it doesn’t light up it is still. a very useful wearable and a compact and discreet on at that.

Having gone hiking with the Energizer headlamp I must say in terms of convenience of having a headlamp is great but in terms of comfort it wasn’t the best experience. Some of the features include. VisionGuard protects vision by gradually increasing light intensity. Low battery indicator. IPX4 water resistant and shatterproof lens construction. Latest LED technology and patented optics, delivering exceptional vision, up to 15X brighter than standard LED technology. 6 Modes High, Low, Flood, Red, Red Flashing, Green. Features LED Technology.
