HELLO POST :)

A design/engineering strength I have is my capabilities with Rhino. Ever since freshman year I have really enjoyed 3D modeling my work before creating a physical version. I love to take on new challenges creatively and I am hoping to use that this semester in analog and digital.

An area for growth in the design/engineering field for me would be everything coding related. So far i have never truly understood it and i really hope to change that mindset. The problem for me is that whenever i believe i have the basics down, something new is always to be learned or added.

Three things I would like to commit to my documentation process are:

High quality photos of my work and progress
informative but concise headers alongside my images
As many steps of the ideation process as possible to show the work i put in

PCB Ideation

Idea #1: For our PCB we wanted to recreate a picture of Shaquille O'Neal's face. For the LEDs our hope was to replace the eyes and nose with four individual lights. Additionally, we want the other details of the face to be silkscreened. As far as colors go, we haven't completely figured out what we want to do. Most likely however, the background will be some shade of brown and the LEDs might be red or green.

Idea #2: As a backup idea, we used the same basketball theme and design a shoe inspired by Air Jordan 1s. In the event that we do use this design the LEDs will have a red color and be placed in parallel.

PCB Board Design & Schematic

PCB Board

During this process I learned how hard it is to add curves to Eagle. It took numerous attempts to limit the amount of points and individual lines. In the end we had to understand that the board is not going to look exactly like the figure we originally wanted. Additionally, our group attempted to silkscreen but due to the board's small size we could not fit anything else besides the circuit.

PCB Schematic

While coming up with the schematic I learned the hard way that once you import the schematic to the board, the wires will always immediately seem tangled. Also, I figured out along the way that it is best to make the schematic as simple and possible and then move around the pieces later once they are uploaded to the board.

Amplifier Ideation Sketches

10 Sketches

These were drawn in class inspired by the prompts given.

Other Sketches

These ideas were drawn in addition to the first 10.

Phase 2 Design Drawing

The reason why I chose these measurements is because I wanted the enclosure to be big enough for the sound but small enough so the speakers could stand out.

The enclosure itself is a simple box so I wanted the details to stand out.

Overall, I chose the cow design because I believe that it is simple enough that I can make changes as I go. However, the idea is different and new so I will have fun working on it.

3D Enclosure Model

Cardboard Enclosure Model

Breadboard

I was successful in finishing my breadboard! My sound works but I have to keep my finger down on the audio jack for the best audio quality.

Python Partner Challenge

My partner, Elli, and I completed challenge #1 of the python coding problems. The challenge was to print a list of names and then find a way to print them in reverse order. To solve this challenge, we wrote a list of names in alphabetical order. Then we proceeded to change to order by using the "sort" command and "reverse" command which has a "true" condition.

AMP PCB Design with Sophie

This is a screen shot of our schematic. We used the original design but took away the switch since the battery will be able to turn the amp on and off.

This image is a screen shot of our PCB board. We additionally add a silk screen image of a cow and deleted the former "lick tiger" and "analog and digital" images.

Microcontroller Coding Challenge with Elli

We completed challenge 3 which had the LED bounce back and forth on the x-axis in a loop. We additionally added to our code that the LED would switch colors every space.

I worked with Elli on this coding project.

Microcontroller Image with Lance

We coded the micro controller to have a picture scroll across the screen and then have some text show up afterward.

I worked with Lance on the project.

Unsoldered Circuit Board

Digital Project

My idea for the digital project is to code a screen to say "moooo" across the screen followed by a picture of a cow. I imagine it working by using similar code from my microcontroller and customizing it to fit my previous description. The only device that I need will be the microcontroller and I have planned an opening for it to fit in my amplifier enclosure.

"Finished" PBC

I worked with Max on this project. The shape of the PCB is the face of Shaq O'Neal. The soldering portion of this project is not completed but I have begun to solder resisters and LEDs into place.

Soldered Amp Circuit

This is my soldered amp circuit. I made it very simple without a volume button or a switch.

Enclosure Build Process

The next step I need to take is figures out how to fix the magnets on the back and keep them from falling down.

To complete my project by the end of the semester I am planning on working on my amplifier after school.

Final Project Completed!

This is an amplifier in the shape of a cow with a screen that says moo. I am most satisfied with the 3D printed legs and the small acrylic pieces I cut out.

If I had to start over I would fix the back. I used hinges so I could have access to the back of the enclosure. However, it left a huge gap that I would like to change.

A lesson form class that I will be taking with me is how to solder better. Since I had to re-solder my PCB I spent a lot of time working on becoming quicker and more efficient.
