Hello Post!

Design/engineering strength: One strength I have in engineering is being able to adapt if my idea doesn't turn out the way I want.

Design/engineering area for growth: An area for growth I have is managing my time better and planning when I need to be done with each step.

Three things I want to commit to in the documentation:

I commit to describing each step in detail
I commit to keeping my page up-to-date and organized
I commit to taking clear and in-focus progress pictures

PCB Ideas:

The idea my group decided on for our PCB is a sheriff badge. We plan to make each point of the star light up and put a pin on the back to create a badge. We chose this design after we found out the board could be a pin, and we thought it would be fun to make.

PCB Board

PCB Reflection

Marcel was my partner in this project and we made a sheriff's badge. One thing I will remember about printed circuit board design is that the schematic doesn't have to match or be the same shape as the board design.

Sketch Ideas

Speaker Idea Sketches

My three favorite speakers that I drew are all easy to take place and are not too complicated design-wise. I chose these because it will leave me more time to add electronic features like lights, and maybe more colors as well.

Post-it Feedback

Most of my feedback was to add lights to my speaker and to add more electronic features to make it more unique. I will keep this in mind while designing my speaker.

Phase 2 Drawing

I believe this design is simple enough for me to complete but also will help me grow while designing the interior. I don't have that much experience working with circuits and I think this design will help me achieve my growth goals. I am challenging my current skill set by adding features like LEDs and a volume knob. I will also be challenging my skill set by painting some parts individually to focus on the visual part of my speaker.

Modeled Enclosure Design

This is my modeled enclosure design for my speaker.

Cardboard Prototype

This is my cardboard prototype for my speaker. My idea is to make my speaker a boombox and from my prototype I learned the dimensions of my design. I need to modify the width of my design on rhino.

Amp Circuit on Breadboard

After prototyping my circuit, I now understand how accurate each piece has to be for it to be able to function. One part that is a mystery to me is the ferrite beads/emf choke. I looked it up and it filters high frequency noise energy and dissipates the noise energy in the form of heat. It's function is to improve PCB's power quality.

Amp PCB design and schematic

I worked with Nalin on this project and I learned that it doesn't matter what order each part is in on the board as long as they are connected correctly in the schematic.

Completed/Soldered First Shaped PCB Project

I worked with Marcel on this project and the original idea was to create a sheriff's badge where each point of the star can light up. I think our board turned out well even though I would have liked it to be a little smaller to make it more realistic.

Final Digital Project Documentation

Github Link!

For my digital project I made a microphone connected to LEDs so that when music plays, the speaker will light up depending on the volume. During this process, I learned how to change the color of my LEDs, but it was challenging to code and understand which parts to change.

Final Amplifier Documentation

The goal for my amplifier was to create a mini boombox that could sit on my desk. I am most satisfied with my digital project because I worked hard on it and liked how it turned out. If I were to start over, I would have ensured each measurement was precise before laser cutting, because I wasted a lot of time recutting my wood. This semester, I got comfortable using the laser cutter and I believe I would still remember how to use it in 2 years.
