Intro Post

An Engineering Strength: I am good at finishing work on time and really committing to my work! Once I start something I tend to get pretty involved with it and will continue until I finish to the best of my ability.

An Area for Growth: I think this semester I have two areas I would like to work on. The first is coding. Freshman year I found coding quite confusing so I would like to be able to better understand it this year. The other area is attention to measurements. Sometimes I make small mistakes that can mess up the final product, so I want to pay extra to the small details.

Things to Remember When Documenting Work:

Remember that the audience does not know the assignment.
Take pictures with good lighting and clear backgrounds
Make sure to document the whole process (even the mistakes

PCB Design

For our PCB design Angelina and I decided to make a decorated birthday cake. The plan is to use LEDs for the birthday candles and to screenprint the rest of the design into the circuit board.

Final Board (in progress, problem with silkscreen)

I learned how to be patient when encountering problems.

Schematic

I relearned what a parallel circuit is and how to read schematics

Top Right Retro Design

Tree

Roller Skate

more detailed drawing of enclosure

I decided to go with a relatively simple shape to allow for my pretty beginner level building skills and to preserve sound quality. I also thought I would be more likely to display and use something in my room if it was relatively simplistic. I decided to go with a more retro inspired shape and nature-y vinyl patterns along with a sun and a moon to make my time of day display.

Rhino Model

Modeling this helped me figure out some of the issues with my design. I was able to better see the dimensions, especially with the box inside.

Cardboard Model

I think I need to

In Progress Circuit

I definitely learned a lot from breadboarding! I had forgotten a lot of what we learned about electronics in Freshman year. One example of something I learned was the importance of capacitors in smooth audio for amplifiers. From my understanding breadboarding to a way to prototype and test your circuit before committing to soldering

Partner Challenge

Bruno and I did challenge #1 (making and reversing a list) in class! To do this we labeled our list mylist, and then applied reverse to that name using the reverse command. Then we used the print command to print our list.

Board

Schematic

This is our schematic and board design for our PCB where I will build my circuit for my speaker. Ella and I did not change much, except getting rid of the switch. The schematic show the parts as symbols and the board show the digital replication of the PCB, with our silkscreen of a cow.

MicroController Activity

Tabitha and I were planning on making a rainbow by coding 7 loops of color to run across our board, but we got stuck and ran out of time so we only made a red loop.

I worked with Mira! We displayed an image of a flower on our screen and displayed both scrolling and still text. This is our code for scrolling text that reads "have a nice day"

Sketch of Digital Project

I am planning on using a screen and having it display a different "have a good day" message depending on the time of day. I am also planning on adding sun and moon graphics. I will need to connect to a clock and code the messages to correspond to the time.

Unsoldered Amplifier Board

Finished Speaker Circut

In progress speaker

What do you need to no next?

I need to screw in my speakers and glue on the front and back piece

What's your plan to complete this by the end of the semester?

I am planning on coming in on friday after school to finish up.

Finished Speaker

What did you make?

My speaker is fairly simple. It is a box-like form with wood engraving.

Thinking about the work you created, what are you most satisfied with this semester?

I am most satified with the circut. I had to redo my PCB and I am proud that I was able to make it work!

If you were to start over, knowing what you know, what would I do differently?

I would try to better understand coding and put a bit more attention towards my rhino design.

What is a lesson from this class that you will take with you and use in future projects?

I think perservence. There were a lot of thing I had to redo, but all that repition ultimtly made my project better.
