Final(ish) design

I made a record player speaker. I am most satistfied with my soldering, since this was the first time I have done it. But at the same time, I wish I had a bit more experience with it so that I could do if faster. Lesson learned: better time management!!

Circuit Board

Soldered PCB circuit board

Circuit Board

Unsoldered PCB circuit board design

Digital project

My idea is to have an OLED screen on my speaker that will have scrolling messages when the speaker is on. So it will use the OLED screen and be used in my speaker design.

Scrolling screen

Partner: Angelina

scrolling screen

Made a message scroll across the screen

Code

Partnered with Bruno

Microcontroller

Code turns on a singular light in the middle of the microcontroller

Board design

This is the board design, which is going to be what the final PCB looks like. Lance and I chose to write "New Manhattan" because that is our friend Catalina's Philz order

Schematic

This is the schematic, which shows all of the connections and different wires. This reminds me more of what you see when you are breadboarding.

Challenge

Write a list of numbers in reverse order

Solution

My_list=[1,3,5,7,9]

my_list.sort(reverse=True)

print(my_list)

Breadboard

(Not complete yet)

One thing I learned was attention to detail while breadboarding because if you skip one aspect, the entire thing won't work

The purpose of breadboarding is to make sure that all your parts work and to test speakers before putting it all together on the circuit board.

Cardboard prototype

I learned through making this that having one slanted side would not work, and be too complicated, so I had to make the whole thing with 90˚ angles, and implemented that change in my rhino file as well

Design in Rhino

Here is the main skeleton of the design in Rhino, there are a few things missing, but this is the overall shape of the speaker

Side/interior view

All the circuits and wires will be in the slanted part of the design, not in the main box

Top view

On the top part there will be a sound adjuster, an LED screen, and the on/off button

I chose this design because I thought that it was a simple enough design that I can finish it, but it also is shaped like a record player, which means that it isn't just a regular box, it also has some interesting aspects to it. So simple enough design that I think I will be able to finish it in time, but also not too simple.

First 4 ideas

three favorite sketches: the record player, the house design, and tv idea

6 more ideas

Schematic

In doing the schematic I learned how to set up parallel circuits and the way that you attach resistors to make sure that the lights don't burn out too quickly

Board

With the board design I learned to make sure that the shape wasn't in two pieces, and got to see how the airwires redraw themselves to make the quickest path from battery to resistor to led, which was really cool

Ideation for Circuit

Amelia and Maya

Design/Engineering Strength:

My main strength will be to put in effort to learn how to make circuits through collaboration and asking questions when I am confused

Design/Engineering Area of Growth:

My area of growth for this class is since I never got to do the circuits component of my lamp in freshman year, this will be my first experience learning how to make circuits, so I will have to learn everything fomr scratch

3 things I commit to doing in my design documentation:

Take clear pictures
Make sure that my pictures capture all aspects of the design
Write thorough descriptions and talk about my design process
