Geometric Motion Lamp

This is our project making a Geometric Motion Lamp.

Project Constraints

This sheet consists of constraints and requirements for this specific project. We have to meet all of these to complete our project correctly.

Geometric Motion Lamp Prototype

This is my Geometric Lamp prototype. To get to the point, we have practiced making cardboard cubes to get better at measuring and accounting material thickness. We are also practicing Single Point Perspective Sketching so that we drew up a plan that we knew would meet constraints, and then we made it.

LED Prototype

After making my first prototype, I used the laser cutter and cut out pp0even polygons for a second prototype. Based on the screenshot to the right, all of my polygons comfortably fit onto the 12x12 piece of plywood. I used the Solid works0/ program to layout my shape for the laser printer and get all my dimensions exact. My shape, a dodecahedron, is very interesting looking. It is not a shape normally found in nature. It also contains all 16 LEDs and uses all colors of the rainbow! My Led patterns include a waterfall effect, a swirl effect, and a reverse waterfall effect. My code tells my arduino when to blink on and off to make my pattern. (It is listed below) Because of the 12 flat sides, this object is freestanding and can be rotated to the preferred side for viewing the LEDs. In my design, I only used 11 polygon shapes so my electronics are easily accessible from the bottom. All of my electronics fit cozily in my design. One of the challenges I faced while making this prototype was an Led. As you can see in the video, that front Led is not working. It turned out the Led was almost burnt out, on the final product I will make sure all my LEDs are bright! Another improvement I will make, is the wiring. The inside looks like rainbow spaghetti soup!

Determining the Joint Angles

In this benchmark, we worked on using math to perfectly sand our lamps. This allows them to fit together with glue perfectly.

Sanding and Dry Fitting

After making my joint to the specific degrees, I used the belt sander to sand the edges of my dodecahedron. Then, I dry fitted my pieces together with tape to make sure they fit.

Installing Copper Tape

In this benchmark, I carefully placed copper tape where my LEDs will be soldered.

Wiring LEDs

After installing my copper tape, I soldered down the shorter leg of each LED and connected all the copper tape by black wire. This created a circuit for the LEDs to run properly.

Hole For Cord

I used a band saw to cut a corner from one of the already chipped pieces. The hole will allow my cord to connect from my electronic to a power source.

Arduino Location

The Arduino is plugged into the breadboard, which has a sticky side. I attached the bread board to one of the pieces of my shape.

Glue Your Lamp Together

I used wood glue and tape to piece together my dodechahedron! It fits nicely with only a small gap.

STEAM Learning within this project

S

The science aspect relates to circuits, and the way the arduino connects with the wires to the LEDs. We also previously know that each of our lights emits different wavelengths of light to produce color.

T

Technology was a big part of this project, this lamp would not have been finished without these technologies: we used paper cutters, hot glue, the laser cutter, and cardboard. We used different plat forms to format our final pieces. First, we measured and perfected our pieces in Solidworks, then uploaded it to Inkscape. We cut out our final pieces with the Glowforge.

E

We included the Engineering Design process in making our lamps. The first step in the procedure is the project brief. We spent some time accepting our constraints. Next, we conducted research by practicing material thickness and angles. Then, we built cardboard prototypes of our designs and constructed our code. After being evaluated, we started producing the final pieces.

A

Art plays a big role in making a substantial design. We had to practice single point perspective with our shapes, but my shape could not be found from a single angle, so I ended up sketching my figure. Going forwards, I am going to paint my shape to give it more of a geometric feel.

M

This project is very dependent on math. We had to calculate the material thickness, angle to assemble, size of LEDs, and make sure it was all inside a 12"x12" piece of plywood.

Constraints

These constraints demonstrate what our final lamp should consist of.

Freestanding

My object can stand without wobbling because of its flat bottom. All of my shape's sides are flat besides the ones with the LEDs.

Interesting Geometric Design

My design is very unique. It holds the shape of a soccer ball.

Use between 8 and 16 LEDs

I used all 16 LEDs on my shape. There are 6 on the top, and two on the upper part of each of the sides.

Constructed on a 12" x 12" piece of plywood

I did not need to re-cut or use any more pieces of plywood than provided.

All electronics fit inside of your design

My design does fit all of my electronics, with room. My cord fits uncomfortably through a hole, which was cut from the band saw.

All electronics are easily accessible

I can stick my hand inside of my design to fix any of my electronics if necessary. I have already had to re-solder an LED.

Your light design must convey a principle of motion

I used many colors to portray the motion in my shape. I used red, orange, yellow, green, blue, and white.

Rotates through 3 light patterns

My design has three light patterns that repeat three times. The first pattern is a waterfall, the second is a spiral, and the third is a reverse waterfall.

Physics Speaker Project

Today we were introduced our sound amplification project.

These are our project constraints.

This sheet acts like a guide for the progression of the project.

Dimensions

Our designs must be 150 cubic inches, this drawing demonstrates the volume and dimensions of the design. The length of my design is 8 inches. The height is 4.5 inches and the width is 4 inches. Overall, the volume is 144 inches.

After brainstorming more, my design changed!

Link to my presentation:

Because of the pandemic Covid-19, we have not been able to continue our normal school routine. If we were in school, we would be building the prototypes of our speakers out of cardboard. Eventually, we would build them out of wood then testing them. We have been continuing our projects from home, which is why we are building on CAD and not making prototypes. We will still have our teachers revise our projects to the most minor detail in the CAD designs. The more we review our designs and rebuild them, the better they will be when they are printed. This setback in creating our designs has a bright side. Staying at home has forced us to become familiar with TinkerCAD which will be helpful in the future.

Some corrections that were given to me were; pull the phone holder up more so the speaker does not flush out the sound the wrong way, and move the phone holder back so the corners aren't cut off.

Constraints

For this project, like any of our other projects, we were given constraints for our designs. In this specific project, we were given 7 constraints. This project would have been crafted from wood if we were at school. But because of Covid-19, we are at home continuing this project. We have been using TinkerCAD to construct our designs, and they will be 3D printed based on those models.

  1. You must complete and document each phase of the engineering design process.

      • Each stage of the engineering process (Brief, Research, Idea Development, 3D Prototyping, Evaluation and Testing and Production) are being recorded here as we move further into the project.

  2. Your speaker must be designed with a client in mind (You will give your speaker to your client in the end).

      • I am going to give my completed speaker to my Dad on Father's day. With all the time we have in quarantine, my Dad has been building shelves and frames for the house. I will give him the speaker as an addition to his "building station".

  3. It must be designed to hold a specific phone model while charging, with the charging port built in.

      • Our teacher decided it was best to modify this constraint. We are no longer required to have a charging port built in, because it is too hard to add on the CAD model we are using.

  4. It must amplify sound by at least 150% as measured 2' in front of the speaker.

      • For this constraint we would take a sound sensor and measure the amplified sound 2 feet from the speaker. Again, due to restrictions from the curtesy of Covid-19, we will not be able to test this constraint.

  5. Craftsmanship of your final product needs to be store quality.

      • I used the plane and align setting on the CAD software we are using to make my design as even as it possibly could be. My teacher has approved my design and I believe it is ready to be printed.

  6. The phone holder must allow the case of the phone to fit.

      • My dad's phone model is an iPhone X. The dimensions of his phone are 2 3/8" in length, 1/2" wide, and 5 3/4" tall. I made the phone holder 3" long, 3/4" wide, and 2 1/2" deep.

  7. Your final design must be made with 150 cubic inches of material or less.

      • Overall, my design is 81.39 cubic inches.


STEAM

S

In this project we had to relate physics with creating our speakers. We had to find the best way to amplify our sound by 150%. We talked about how sound waves bounce to reach the focal point. The focal point would be 2 feet away and it would be measured by a sound sensor.

T

Because of Covid-19, we have a setback in the technology portion. We are no longer creating our designs out of wood, but we are 3D printing them. Because the software Solid works is not available on certain computers, we are using TinkerCAD. TinkerCAD has helped each of us create our designs.

E

Engineering has been involved through the engineering design process. Brief, Research, Idea Development, 3D Prototyping, Evaluation and Testing, and Production. For our prototypes, our teachers have been reviewing our designs over the CAD software. It has comedown to the smallest measurement to make our final designs. We have been documenting the procedure on our google sites.

A

Art was the first part of this project. All of us had to come up with a unique design for our speaker, which was not on the internet. For the 3D printer filament, we are allowed to pick colors. So the printed design will have a colorful skin.

M

For this project, one of our constraints was to not have our volume over 150 cubic inches. We had to calculate the volume of each piece of the speaker and subtract what was dead space. For my project, I had to calculate the volume of a dodecahedron, rectangular prism, and two cones. I then subtracted the volume of the rectangular prism and of the 2 cones from the dodecahedron. To find these numbers, we had to do some measuring.
