Hello Post!
A Design/Engineering strength that I have is having a thorough ideation process. I love coming up with different designs so that I can come up with the best idea and work up to my full creativity.
An area for growth is my understanding of coding. I only have very little experience and would like to expand my knowledge on the works of coding.
3 Commitments in my documentation of my work
Providing clear and high quality photos of my work
Writing concise, descriptive, and easy to understand headers that go along with my photos
Staying on top of my documentation process/being sure that I have posted and am up to date
We decided to go with the strawberry design because we thought that it had an easier shape to make and import from Rhino. We are still working through our ideas on how to go about the strawberry design but we were going to have each of the seeds be the lights. We would also silk screen the stem part of the strawberry on and of course use a red circuit board.
I worked with Sofia, and together we decided on a strawberry shaped circuit board. We made the leaves with silkscreen, put the battery on the back, and put the LEDs where the seeds would be. Something that I would like to remember about this process and carry into future projects is patience and persistance. Some parts of this project brought challenges and some problems but my partner and I were able to work around them.
Out of the three designs that I circled, I really like my idea of the stain glass window and I will most likely go through with. My only concern is that you will be able to see all the components inside, as my plan is to have the stain glass part be different colored acrylic. Another concern is getting the pieces of acrylic to stay together and hold up the speakers.

Boom Box Speaker Design
The materials that I was thinking of using was wood for the main structure of the box and then using acrylic for the small buttons and designs.
I am a little uncertain on where my opening will be so that I can access the mechanics on the inside of my speaker. I also wanted to make it so that the handle could rotate a little.
Cardboard Prototype of boom box
The two holes in the front of my prototype are where my speakers will be placed. At the top is a handle that I hope to make to rotate and be able to pick up my speaker from. I still have to work out where exactly I want all my buttons and little add ons to go, so that it resembles a boom box more. When I do get my materials and build my speaker, I will use acrylic and cut out small shapes to add onto my speaker to be like small buttons and switches.
Circuit Breadboard
Here is an image of my circuit board that connected to two speakers and to my computer to then play music through those speakers. Something that I learned while making this was patience and being sure to check over the tutorial and making sure I have followed all the steps. Although about the circuit itself I learned more about the connectivity of all the components of the circuit in order for it to work.
Here are images of the schematic and the board that me and my partner, Lizzi, worked on together. We were able to divide up the work because any time someone was working on the computer the other partner was helping them by showing them where the connections went and helped them through the process. That way we were able to reach the 10 minimum contributions. Something new that I learned more about is how important each small connection is and how if one small mistake is made the board may not be able to work. I realize now the necessity of patience and taking each step slowly.
Me and my partner today, November 2, we tried the temperature senor and we were able to detect the temperature of our fingers. I put my hands on my cold water bottle and brandon tried to make his hands as hot as he could by rubbing them together.
Microcontroller code testing
Me and my partner were able to test out some of the codes and here is one example of the scrolling text and image.
Microcontroller Challenge
My partner and I were able to do one of the challenges, which was getting the API data and displaying the temperature in San Francisco on the screen.
Digital Project Design
For my digital project, I want to have something simple and effective. So I would like to have the time displayed on a small screen on the microcontroller. This would be showing through my entire speaker design so that the time is shown on the front of my speaker design. My hope is that it would blend in with my other buttons and designs of the boom box.
Amplifier
This is what my amplified looks like before any of the pieces were soldered on. My original one that I made with my partner had some missing connections, so this is one given to me by Mr. Klinedolf.
Shaped PCB Project
I made this strawberry shaped PCB with my partner Sofia. The LEDs light up reoresenting the little seeds of a strawberry, although one of them is dimmer/doesn't work as well.
Soldered Amplifier Circuit
While making my amp circuit, I got better at soldering and problem-solving. I also have a little bit better of an understanding of how the circuit board works.
Build Documentation
I was able to cut the pieces of wood, that would make up my enclosure. Unfortunately, I ran out of time and couldn't put them together.
This is an image of the peices laid out how it would have been put together. The last steps to complete my speaker would be to make my digital project, and make the metal handle on the top.
Reflection Questions
I was in the process of making a boom box speaker and I am most satisfied with the way that my speakers sound. And I am also proud of the way that I constructed my circuit board.
Something that I am most satisfied with this semester is the way that I was able to learn new skills and become more knowledgeable about electronics.
if I were to start over, I would have made my pieces press fit and been more efficient with my time by preparing my rhino file better when I was creating my prototype.
Lastly a lesson that I learned was to go with the flow of the project. To also not let dilemmas and problems set you back. I also improved my skills in soldering and collaboration.
