One design strength I have Is the ability to make up creative ideas and execute them. An area of growth is that I often struggle to revise those ideas as I often become very attached to the original premise. I want to commit to giving clear, interesting, and concise descriptions for my documentation as Learn to work with circuits.
These are the three sketches that I did for a potential PCB with my partner Lauryn Lacap. Because I was sick The day we did this, I did not see my partner's sketches, nor decide on the best design among them. That said out of these my favorite is the hand. The design was inspired by a specific show I loved as a kid and I thought it would be nice to pay it tribute.
We choose the hand from the six sketches after looking at both of our sketches. My partners are below
This is the schematic for me and Lauryns PCB. We had some initial issues with Fusion and the efficiency of the original design. However, with some effort, we were able to fix our project and make it functional. Aside from the oddity of the black background, the design pushed to electrical components fine indicating the company will be able to make the design without any issues.
The following images are the circuit schematic, the circuit board visual, and the 3d model of the electrical components, in that order.
These are the ten sketches I did to plan for the eventual construction of my amplifier. Out of these my favorite were the museum display (4) the chromatic box (2) and the half moon (10) simply because I like how they look
I received feedback on my ideas on these post it's. There were a majority of the class preferred the half moon design which i'll consider in my final decision but I also like both other designs . I didn't receive much feedback other than one person who disliked the face n the moon which was intended to be creepy.
This is the final sketch of my amplifier. It's an alteration of my original Moon-man design, and in my opinion, it's much better in my opinion from an appearance perspective and far more achievable from a time perspective
This is the rhino design for my design. I may need to make some changes in the future, but it's, for the most part, complete.
This is my cardboard model. While it's not perfect and could use some tweaks, it's dimensionally accurate, which is the point, and it gave me a good sense of how I needed to construct the final project. It's worth noting that I've chosen to relocate the speakers from the eyes to the sides of the amplifier, though that isn't reflected in the model
My completed bread Board
this is the complete breadboard for my speakers. Though it took a bit of tweaking (and two blown capacitors), it is now fully functional. I will have to re-organize the circuit on the PCB to make it smaller to suit my box, but that's a pretty minor change. After prototyping The breadboard and having several issues with getting the speakers to work, I realized the potential difficulty I might encounter in the future with soldering the actual circuit as a small mistake could mean restarting. An element that I didn't fully understand in terms of function was the voltage regulator. According to Google, a voltage regulator helps maintain a fixed voltage output and keeps the amount at an acceptable level for all the other components.
My PCB design
This is my PCB design, I worked with Kaeylyn to create this design with each of us building aproximately half the schematic. During this project I gained a better understanding of fusion for if I use this program in the future.
Circuit Board
The assignment wasn't posted on Blackaud when I started soldering so this is the earliest image of my board.
My shaped PCB
This Is my complete and soldered PCB. The LEDs are a bit dimmer than I was expecting, but other than that, it turned out extremely well. It's worth noting that the light is on in this picture, but it's somewhat difficult to tell from the photo. Thanks to my partner Lauryn for working with me through the design process. In terms of design, it's exactly like the original plan which was a hand with an LED on the base of every finger finger and a button.
My Digital project design
For my digital project, I plan to make use of the Three buttons on the side of the microcontroller and make rock paper sisters. I'll use the extra wood from my enclosure to laser-cut the RPS and attach it to the side.
My compleated PCB with bluetooth.
This is my completely soldered circuit It's as if now fully functional and can play music from my phone
My Completed Amplifier and Enclosure
The intention of my speaker was to balance the difficulty of assembly with aesthetic appeal which I think I succeeded at. Out of all of my projects, this Is the thing I'm most proud of. if were to re-start this project I would have made the entire thing larger making the press-fit and the wiring easier to work with. While I learned a lot of extremely helpful things this semester the most important was probably persistence, and learning to run with something imperfect.
