My name is Ava Dornseif and I am a current sophmore!
My design/engineering strength is passion and dedication to my projects and being willing to put in work to make it turn out the way I want to! An area for growth is being able to adapt and change a design if something isn't working and being innovative during the process of building a project if it needs improvement.
When documenting my work, I want to commit to keeping my site organized and easy to follow, posting good pictures, and adding extra detail to make it look nice and distinguish different elements.

My partner is Fernanda!
Our current design for our PCB is a soda bottle! Our plan is to have the outline of the circuit in the shape of a Coke bottle and place our 12 LEDs around the rings. We also want to come up with a name for a soda brand that is specific to us and silk screen it on the top.

When making this circuit, I learned how to read a schematic and what each of the symbols mean in the diagram. I saw the real-life benefit of a parallel vs series circuit, as a parallel circuit increases the voltage and brightness of the LEDs, while the opposite happens if you have multiple LEDs in a series circuit. I also learned that the circuit outline had to be made as one continuous line on Rhino in order to become the dimensions of the circuit board.

Fernanda and I created a soda bottle circuit, and here is the finished design, complete with all of the parts soldered onto the board!

Here is the first step in the process of building a speaker: ideation. These are a few of my favorite design ideas!
September 15, 2022
My speaker is going to be a hand of cards with an ace, king, queen, jack, and ten, which is also a royal flush. I'm going to build the front card as the box that holds the speakers and add wooden pieces behind it to represent the other cards and add acrylic over the little design embellishments on the corners. I chose this design because I wanted to do an object for my speaker and thought this was a cool concept, plus it would be simple yet a put-together piece that hopefully won't be overly time-consuming because I would like to complete it during this semester's class.

Here is my Rhino model! I am going to cut out the wood with the flat outlines, but I designed the pieces it so that all of the sections involved in the box fit together like a puzzle and don't require any glue.

Here is my cardboard model! The actual wood will have thickness so the edges won't stick out and the heart in the middle was turned upside-down, but I am really happy with how it looks!
From my prototype, I learned that the dimensions for the speakers have to be exact, as I had to change the locations of the cut-outs on the front so that the speakers could fit into the box.
I am considering adding some engravings or more acrylic to the pieces than I currently have to give it more decoration, and I still need to decide if I want to incorporate my digital project into the speaker.

This is my completed circuit on the breadboard!
The most important thing I learned through this process was the different parts of a speaker and how the amp works. Through assembling the circuit, I was able to see all of the different portions and undestand how they contribute to make it play sound.
Another little thing I learned was the importance of good connections between pieces. When one of the components would come loose/not be fully attached to the board or the wires were in the wrong place, the entire circuit wouldn't work.
I see the purpose of breadboarding to be initial assembly and testing the circuit before permanently soldering the connections together so that you can make adjustments in the beginning and make sure everything works correctly.

Here is the completed PCB for my amplifier, which Marisa and I made! The viewer is looking at a simple circuit board that contains all of the parts that went onto the breadboard. The silk screening has the different card suits to match my speaker design, and it will be printed in red to match the acrylic I am planning to add!

Here is the board before I add my soldered pieces!

Here is my finished circuit board - it's ready to go into the speaker and play music!

Here is the process I went through to build and assemble my speaker!
December 8, 2022
Progress report: I've assembled the main base and attached the speaker to it, now I need to finish attaching the cards to each other and add some minor details. My plan is to come in outside of class to cram and do the digital project for homework.
I decided to change the design from my original because Mr. Kleindolph told me that the it looked visually heavy on the left, so I took his advice and spread the cards out on both sides to balance the design.
December 14, 2022
I made a deck of cards! The hand is a royal flush, and the speakers are in the ace while the rest of the cards are fanned out behind it.
I am most satisfied with the details of it and the engravings because they were so much fun to make and add some flair to the enclosure.
If I were to start over, I would change some minor things. I would have tried to design for more tension between my edges so they held together better without glue, added a cutout for the on-off switch so it can be accessed more easily, and changed the color of the heart on the front becasuse it blends in with the speakers a little bit.
A lesson from this to take to other projects is flexibility and changing/adapting as I create. I made a lot of adjustments, both creative and technical, as I was building, which I am proud of because this was one of the things I said I could improve on in the beginning of the semester.

The challenge was to create some code that would generate 10 random numbers from 0 to 100 and hav the program print out the highest and lowest numbers. The solution was to import the random module and code for a list of 10 random numbers from 0 to 100. I also wanted the computer to print the list of random numbers, which was optional. I coded for the list's max, or highest number, and min, or lowest number, to be printed as well.

I worked with Quincy today, and we programmed four quadrants on the neopixel grid to show a specific color and light up at different speeds.

I worked with Atticus today, and we programmed the microcontroller with different combinations of words and images, ending with a scrolling image of the poop emoji :)

My idea involves the OLED screen on the Feather M4 Express. I want to keep it simple but stay on the theme of my speaker, so my plan would be to code little playing card jokes/puns and pictures of the card suits to scroll across the screen. I have to see my speaker design allows me to plant it in somewhere, but I would also be fine to not attach it altogether.

Here is my digital project! I kept it very simple and just coded my OLED screen to flip through card game phrases.
