Geometric lamp

I made a geometric lamp and made a "T". My lamp is freestanding because as you can see in the video it stands up by itself. My lamp is a interesting shape because the top of the "T" is uneven to the bottom. My lamp meets the 8-16 LED's constraint because my lamps has 12 LED's. It used to have 16 but i changed it. My light patterns show motion because it goes in different orders to go from one end to the other repeatedly. My lamp has 3 patterns as you can also see in the video. The video also conveys it being accessible to the wires. When doing the planning of my designs i made a 12x12 square on graph paper and mad a sketch of my lamp.

My code:

int led2=2 ;

int led4=4;

int led6=6;

int led8=8;

int led10=10;

int led12=12;

int led3=3 ;

int led5=5;

int led11=11;

int led13=13;

- STEAM CONNECTION

Science

We used wave length of light with the LEDs. We used arduino to code and while using the arduinos we transferred energy. We created a circuit with the copper. When the energy flows through the circuit it transfers energy into the light .

Tech

I used technology by using machines and we used electronics to code. One of the machines we used was the laser cutter. I coded the light to show movement and repetition of three patterns.

Engineering

I used the engineering design process to create my geometric lamp. To start I had a project brief to understand my constraints. I then researched and practiced assembling materials. I then built a prototype to see what I can make better for the final. After my evaluation of my design I practiced coding . After all that I was able to make a final lamp .

Art

The art design process is very much the same compared to the engineering design process. We used our creativity to think of a design . We sketched the design. we also did a 3D perspective of the drawing . We also sketched the drawing to figure out if our lamp would fit in the 12'' x 12'' constraint.

Math

For math we figured out our angles. I did not have to figure out my angles because of the shape that I chose I got all 90 degree angles. I also had to calculate the thickness of the material to see how long I needed other pieces to be based on the thickness of certain pieces. I also had to make sure I fit our lamp in 12''x 12 '' plywood.

SOUND AMPLIFICATION SPEAKER

Eleanor Sanders (1).pdf

Project Brief

In this project we will be making a homemade speaker that amplifies the sound by 150%. The constraints are, you must complete and document each phase of the engineering design process. Your speaker must be designed with a client in mind(you will give your speaker to your client at the end). It must be designed to hold a specific phone model while charging, with the charging port built in. It must amplify sound by at least 150% as measured 2' in front of the speaker. Craftsmanship of your final product needs to be store quality. Your final design must be made with 150 cubic inches of material or less.

- Research: Homemade Speakers

Design research was originally primarily research for just the design of an item, but research is to look up within the process of design or research-based design practice. This is to get an idea of what you want to do or how to do it. I searched up " Homemade wood speaker that amplifies sound by 200%," and I found pictures that I am really interested in. Research is not only searching the internet to look at articles about how to make certain designs or look at pictures. When researching you can also look at videos. When searching for videos for my homemade D.I.Y. speaker I searched into the search engine " Homemade speakers with wood." This is the videos I watched when searching for videos:

- Physics of Sound Amplification

Sound can be amplified in a number of ways. One is by providing more energy. Sound can also be amplified by an electronic system by making circuits. Sound can also be increased by funneling it into the ear. Physics of sound is very important for my homemade wooden speaker project because knowing the science behind sound helps create a design for my speaker that can amplify sound pretty well.

- DIGITAL PROTOTYPE

JPLV0869.MP4

The reason I had to make a prototype online instead of physically making it is because there was a virus spreading called the Corona virus. Therefore we were out of school doing work from home.

The purpose of designing and testing is so our final product can be perfect and batter than the prototypes. So we test and keep rebuilding till it is perfect. We evaluate so we can get feedback for what we need to improve.

Usually we would present our prototypes at school, but since the virus caused schools across the world to close we present our designs digitally.

I need to change:

- my measurements so my speaker can meet the requirements of 150 cubic inches

- Improvements to Speaker

I changed the design because how I designed my speaker they can watch a video without holding it, and before the part that amplifies the sound was off to the side. Therefore they wouldn't be able to hear as well. So I changed it to where my audience of my speaker could hear the sound better.

- HOW STEAM CONNECTS

SCIENCE:

This project contains science because of the physics of sound. One example is by providing more energy. Sound can also be amplified by an electronic system by making circuits. Sound can also be increased by funneling it into the ear.

TECHNOLOGY:

Technology means "machinery and equipment developed from the application of scientific knowledge." Technology is incorporated in this project because it is a piece of equipment that does action through scientific knowledge. When amplifying the sound there is scientific knowledge needed to accomplish that. I also used tinker cad which is a website , to build a prototype of my speaker. I also 3D printed the speaker.

Engineering:

Engineering is apart of this project because I used the engineering design process to create my speaker. To start I had a project brief to understand my constraints. I then researched and practiced drawing and making my speaker. I then built a prototype digitally to see what I can make better for the final. After my evaluation of my design I remodeled my speaker . After all that I was able to make a final Speaker that amplifies the sound of a iPhone 6s.

Art:

I used art in this project although the art design process is very much the same compared to the engineering design process. I used my creativity and great thinking to sketch my design. I also did a 3D perspective of the Speaker .

Math:

I used math in this project so much. I had to find the volume of the entire speaker, and because of my design it was a lot. I had to find the volume of my trapezoidal prism. Then the volume of the base of the speaker. Then subtract the volume of the space i cut out so that the speaker can hold the phone. In all my volume was 95.875 cubic inches squared.

- Constraint Check

For M first constraint, I had to document each phase of the design process in our google site. The phases of the design process are: Brief, Research, Idea Development, 3D Prototyping, Evaluation and Testing and Production, and as shown above I have documented all of of the 8 phases.
Our second constraint was that our speaker must be designed with a client in mind. I built my speaker for my older sister. I am really excited to give it to her on her birthday, May.11.
Our third constraint has been exempt from the project
The forth constraint was that the phone speaker had to be able to amplify sound 150% as measured from 2 feet in front of the speaker. However we cant measure the sound because the sound amplifier measure was at the school and because of the disease i told you about above we had to start doing school work from home.
The fifth constraint was that our design needs to be store quality. My CAD file is wonderful and was approved by my teacher for being good to go.
The sixth constraint is that it must be designed for a specific person with a specific phone. I built mine for a iPhone 6s. It is 3 1/2" long and 5" inches tall, and a 1/2" wide.
My design had to use less than 150 cubic inches of material and I made sure of that. At first it was over the constraint then i got advice from my teacher and when i fixed the problem i fixed it now the volume is 150 cubic inches.
The final constraint that was added late was that it must be within 6.5”x6.5”x6.5”. My design’s dimensions are 5”x5”x6”.
