Module 3

Workshop 1: Bodystorming

The photos below are from the Bodystorming Workshop from Week 11:

Learning about Bodystorming and how we can use it to uncover hidden pain points in a process and develop innovative solutions.

Our prompt involved streamlining the process of finding a specific resource in a large library.

<b>Acting it out:</b> Here I played the role of a librarian helping out a patron simulating a disability (in this case, a visual impairment).

Helping out the patron. This is only the first of different re-enactments we did to discover the best possible way to streamline the process of finding a specific resource for our patron.

<b>What if?</b> <br> Here we wrote down various scenarios that could occur during the checkout process. We also wrote down various design solutions for the physical space within the library.

Workshop 2: Soldering

The photos below are from the Soldering Demo from Week 12:

Clipping the wires onto the ’helping hands’ while we wait for the soldering iron to heat up

Soldering the first wire

Letting it cool before moving onto the next wire

Testing the newly-soldered wires, with the LEDs flashing colours successfully

Learning more about soldering care & use from this Week 12 demo

Activity 1 Research: Back to the Pulse Sensor + Testing the DHT20 Temp/Humidity Sensor

Completed with: Emily Revell

Testing another peer’s Pulse Sensor, making sure that it is covered with a cling wrap to protect it

With the Serial Monitor showing typical/normal numbers for BPM, we figured out then that the issue was not the code, but rather the sensor itself

The DHT20 Temp/Humidity Sensor

In this first test, temperature stayed at 22℃ even as we wrapped our hand around it

In this second test, we continued encountering the same problems, leading to our search of a possible solution: using the DS18B20 Temp Sensor, which is better for skin-contact.

Activity 2 Research: Testing the new DS18B20 Temp Sensor + Connecting to ProtoPie

Completed with: Emily Revell

The new probe sensor we bought from Amazon, which is commonly used in wet or harsh environments, such as aquariums, greenhouses, & soil

Compared to previous sensors we tried, the DS18B20 showed evident rise in temperature. We finally got to see the values reach 30℃ and above.

The ProtoPie Connect-ready version of our Arduino sketch

One of our many attempts of connecting ProtoPie Connect with our prototype on ProtoPie Studio

Checking to see if there was active communication between Connect and Studio

Additional Research or Workshops

Completed with: Emily Revell

My groupmate Emily and I got in the habit of taking close-up photos of our wiring for easy reference. My goal in the future, however, is to get in the habit of creating proper circuit diagrams so that other group members could easily replicate our wirings if needed.

Stripping the wires attached to the DS18B20 Temp Sensor. These wires were much thinner than regular copper wires, and so we had difficulties stripping it without the wires getting frayed.

Installing new libraries on Arduino IDE for our new Temp Sensor

Testing the sensor in extremely cold temperature. If the data that appeared on the Serial Monitor continued to drop down to 0℃, then it is safe to assume that the sensor is recording correct temperatures.

Taping the wires onto the breadboard. Unlike regular copper wires, these ones were not thick enough and would therefore get detached from the breadboard frequently. Our goal was to find a better solution later in the process.

Project 3 Final Prototype

Despite not achieving our desired result, we were still able to put our physical prototype together. With the probe sensor inserted onto the new patch/band on the stuffed animal’s arm, we used our laptop to watch the temperature values change on the Arduino IDE Serial Monitor as testers held/hugged the plush toy.
