Hello Post

A design/engineering strength I have is my ability to solder. I remember last year I was pretty good at and had a somehwhat steady hand which helped a lot!

An area for growth in the design/engineering field for me would be working with Rhino. I have definitely forgotten some of the skills that I learned in Rhino last year, and need to look back at old work to remember all the tips and tricks when using Rhino to design things.

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

Showing progress photos throughout the process
Having clear, high quality photos of my work
In the descriptions, writing more about what is less obvious in the photos

PCB Idea Design

One design that Sachi and I had was a Christmas tree! We wanted to include 8 LED lights in our design, preferably some of them being different colors. The base of the board would be green, and have one light at the top of the tree (like the star.)

PCB Board

Schematic

This is the design that Sachi and I made for our schematic board. We had some difficulty creating it but learned to always save our progress.

Eagle Design

Sachi and I finished our board and schematic design of a Christmas tree. Here is a screenshot of the final design that will be printed!

Speaker Designs

Favorite Designs:
#2 Cactus design with 2 separate speakers

#10 Snowman design with 2 speakers together

#1 (last page) Smiling box with hat and bowtie with 2 speakers together

Snowman Speaker

The speaker will be in the design of a snowman. It will incorporate both speakers A and B, and will be 11 inches by 4 inches at its widest points. The carrot and hat will be 3D printed, and the eyes will be LED lights. It will have 1 piece of wood in the front (all connected).

Here are some photos of the Rhino design of the snowman, both in 2D and 3D.

Snowman Cardboard Prototype

From prototyping my design with cardboard, I learned that putting together the "box" pieces in the middle between the snowman faces is difficult, and has to be very precise otherwise the snowman will be lopsided when standing up.

As of right now, I think I am going to keep everything the same, but later on in the process, I might make a few changes.

Bread Board

I have finished putting together the breadboard, both with a wire and with Bluetooth.

One technical thing that I learned was that since the small wires are hard to bend once they are placed into the breadboard, it is easier to bend/shape them before and then place it in.

The purpose of breadboarding is to further my skills in using electronics and to also test that all the parts work.

Python Challenge #1

In the first challenge, I created a list which I printed on the right hand side screen, then printed the same list but backwards, so the text appearing on the black screen on the second line was flipped.

PCB Design

This is me and Maya's PCB board design. The first picture is of the schematic, and the second one is digital version of it with the airwires. We added our names in the bottom right hand corner.

Microcontroller

I worked with Maxwell. We made our microcontroller have the lights move across the screen, and tried to make a "V" shape but got stuck and ran out of time.

I worked with Sophie. We made our microcontroller say different words and and made a picture of a flower show up.

Digital Project

I want to program the LED screen to display the time. It will be outside on the bottom right hand of the speaker and will be battery operated. It will have a motion sensor, so if someone is close, the time will show.

Circut Boards

These are two circuit boards. The one on the left is an unsoldered version of the one going in my speaker that I made with Maya. The one on the right is a soldered one that I made with Sachi.

Speaker Enclosure Process

Next, I need to cut out a nose using orange acrylic. I will also add smaller details like eyes and maybe arms.
I think that I will have enough time to finish it in class if I am focused.

Final Speaker

I made a snowman speaker
I am most satisfied with how "clean" the speaker looks
I would maybe want to add a smile or arms to make it look more snowman-like
One lesson that I took away was how to solder.
