Grad Celebration Hat
DESCRIPTION

I worked on the integration assignment.
I chose to make a grad cap as my wearable as that sparks joy for me. This year I will be graduating and completing my undergraduate degree in computer science. I will be the first woman in my family to graduate from post secondary. To celebrate this I wanted to create a project that would both allow me to wear and show off my learning to the celebration and also have a memento from the celebration.
I wanted to have confetti, music and lights as well as sound and the tassel as my input (photo interrupter). These mappings work well because celebrations have noise and a tassel is an important part of a grad cap. I also think music is a big joyful part of celebrations.
I included the Dino as I love Rex and also based on the German PHD hats (DOKTORHUT) I wanted the hat to be able to hold special mementos for the student which for me was the Dino that I learned to make at the makerspace.
A description of why I chose to do this project
Transcript:
A few years ago, I was stepping out of high school, excited about what was next. I had no idea where this journey would take me, but I knew one thing for sure—I was ready for adventure and ready to make every moment count. I have had countless graduations throughout the years (kindergarten, elementary school and highschool)but the next one is special! I will be the first woman in my family to attend and graduate from post secondary! This year I will graduate from university, my cousin from highschool, my brother from elementary school and my other cousin from kindergarten!
University came with its own set of challenges and surprises. I dove into this experience with excitement, meeting new people, and learning tons. I attended events, volunteered and participated in clubs. I got to take many classes I was interested in and learned a lot!
And now I only have one semester left before my convocation!
The hat itself is a nod to my journey. The base of the hat is made from my actual grad cap from highschool. In honor of my university’s awesome Dino mascot rex, I created this little guy inside my grad cap which I learned to solder in the maker space. Placing the tassel activates the rick roll is as a nod to an assignment I had that said we should be able to rick roll each other using our musical device. The foam beads represent the joy I am feeling about graduation and the wonderful time I have had at the university of calgary. And lastly the led lights and sound sensor are because graduation is a time to be loud and celebrate and makes the cap a perfect accessory to wear to a celebration!
The cap is a reminder of all the moments that made this journey so special—and a little bit of fun, of course! It's a symbol of the work I've put in, the creativity I’ve embraced, and the exciting next steps.
Every time the fan goes on, the beads jump for joy. It is a perfect decoration for when you are not wearing the hat and a wonderful reminder of a joyous day.
University life has been full of challenges and triumphs. I havelearned, grown, and made memories I’ll cherish forever. And now, just four months away from graduation, I can’t help but smile thinking about how far I’ve come and this interactive grad cap is a perfect way to visualize that joy.

Concept Development + Final Artifact
Materials Used:
Components
- Arduino Uno
- Resistors and jumper wires
- Speaker
- Motor with fan attachment
- sound sensor (ky037)
- photo interrupter
- WS2812B Led strip
- Breadboard
Other materials
- 4 5x7 frames (plastic not glass for weight)
- foam beads (also tried fake snow and glitter but
preferred
- 3d printed "rex" dinosaur and soldered board for led eyes
in the Schulich Maker space
- yarn
- hot glue
- tulle
- black fabric
- black paper
- glitter paper
- power bank
- grad cap (from my grade 12 graduation)
- tassel
- cardboard box
- 2 faber casttel water pots (but can use other items to place motor and hide it)
How It Works:
1. The sound sensor controls the lights flashing between green and red when the threshold is reached. This works great with music and also conversations as the lights dance to the beat
2. attach the tassel and prepare for a surprise song (I currently have it set to rick roll lol).
3. Additionally set it on the table and attach the tassel to see a beautiful surprise of dancing beads after being rick rolled which makes for a perfect keepsake and display item reminding you of your joyous graduation.

I got the idea to include the confetti in a container instead of launching it after advice from Lora (it may not be joyful to have confetti everywhere messy lol and also harder to do it again and again). While in Costco I saw some beautiful decorations which had automatic snow globes in them. I searched how I could do this and found YouTube ideas that used fans to blow glitter or foam and decide it would be a perfect way to include confetti in a non messy and continuously usable way.
