Strength and Growth
I think I am generally pretty comfortable with the process of coming up with a design. Normally, I'm pretty happy with my designs.
I only have basic knowledge of the electrical engineering we're gonna do in this class.
Commitments
I want to take pictures throughout the process rather than finishing and then trying to take progress pictures
I want to keep my page organized
I want to write good descriptions that I can look back on
We chose this design (top right), a silhouette of our friend group, because it's both creative and unique to us. It also has more meaning than just a cool-looking shape and is something that will remain relevant and special for many years.
Description of what you made
We made a circuit board in the shape of four people. The silhouette comes from a photo of our group of friends (Christopher, Cillian, Charlie, Jake in order). We traced an image in Rhino and imported the outline into Fusion. The circuit board will have 4 lights in parallel, 1 for each person. Each light has its own switch, so we can illuminate different combinations of people. This is all connected to a coin cell battery.
Who worked on this project
Christopher and Cillian
One or more things you will remember about printed circuit board design.
I will remember to have lights in parallel when you can, so that each can be the same brightness. I will also remember that you can make your circuit board any shape by importing a Rhino file into Fusion.
Main takeaways from feedback:
The organic shape of an airpod might be hard to print
I would only be able to use one speaker if I only made one airpod, maybe make two
some design ideas: volume control, stand for the airpod, lights
Design Sketch 2
Reflection:
Why do you believe this is an excellent design to design and build?
I think this is a great design because its creative, its a challenge, and its a design that I am going to be happy with when I am finished.
How are you challenging your current skill set?
I have never really used the 3D printer so its going to be a major challenge to figure out how to use the software and print such organic shapes in a way that actually works. I have also never worked with such organic shapes in Rhino or other 3D modeling softwares.
Model Progress 9/28
At this point I have the screw holes and the place to mount the speaker and I also figured out how to give the model thickness. It's pretty much ready to print. Just need to figure out the final size I want.
Next steps
Finalize dimensions (including thickness and speaker choice)
Make speaker mount in Rhino
Minimize supports and test print
Notes:
Use Milliput to smooth 3D print

What is your idea?
My idea is a 3D printed oversized airpod. The speaker and all electronics will be inside the airpod. The speaker will emit sound at the same place where a normal airpod emits sound. I will add a volume nob and a charging hole to the outside.
What did you learn from your prototype?
From my prototype I learned that I might need to make my airpod a little larger to fit all of the electronics. Through making the prototype I also learned where I should but volume nob and charging port.
Does your design need modifications?
I needed to make the design a little larger. I might have to add an additional support piece or slightly change the location of volume nob and charging port.
Amplifier Circuit - Breadboard
Is there something about the circuit you understand now that you've spent time prototyping it?
I now understand how each component is necessary to make the whole circuit function properly.
Name one part that is a complete mystery to you. Look it up on Google or Generative AI. What does it say the function of that part is?
How does a potentiometer control sound?
Google AI overview: A potentiometer controls sound by acting as an adjustable voltage divider, which regulates the amount of electrical signal sent to an amplifier. It has a resistive track and a movable wiper that changes the resistance in the circuit as the knob is turned, allowing you to increase or decrease the signal's strength, and thus the volume.
