Phone Holder
Phone Holder
This was our first project where we had a projected user. We were assigned to choose a client, study their desk & behavior, and then designed the perfect phone holder for them. I created a simple design that could hold any phone, keys, and miscellaneous desk objects.
Scrap Wood
Scrap Wood
For this project, we were allowed to make whatever we wanted, although it had to be made from the scrap wood in the back of the classroom. I decided to create a Harry Potter and Astrology inspired lamp. It took me roughly a month to construct.
Exterior
The exterior was painted with dark green paint from Lowes.
Light
The light I installed was bought from Ikea.
Reverse Engineering
Reverse Engineering
This project was introduced after Spring break and we were told to split into pairs. Then, we chose mystery gifts to be assigned to our toy. Afterwards, we got started with taking the toy apart. The goal of the project was to get the toy to work properly again.

20190821_151558.mp4Prototyping
We started this project by prototyping our hinges with styrofoam a wooden dowels. I created up to 6 prototypes until I got to the perfect design. Then, I 3D printed my hinges using the program TinkerCAD.
Creating
We next started to construct our box. Using biscuits and wood glue, we connected our 2x4s. Before I assembled my box, used our class's CNC to carve my name into the front panel.
Finishing & Installing hinges.
I came to MakerSpace on Saturday to stain my box and apply my hinges. By monday, it was complete and ready for touch-ups and small adjustments.
Moire Kinetic Sculpture
Moire Kinetic Sculpture
Moire_Kinetic_Sculpture.pdfProject Brief
Project Brief
For this project, we are creating a moire kinetic sculpture. We had to include two independently rotating moires, it has to be gear driven, have 6 or more color changing leds, 3 or more motion patterns, 3 or more led patterns, have professional level craftsmanship, and it has to all be within the materials budget. For the honeycomb sheet, we had to complete different benchmarks and get each of them stamped.
final_5d93f089ba54b60013b59082_650944.mp4Creating a Gear Box
In our first benchmark, we had to build a simple gear box that had the parent gear rotating twice as fast as the child gear. To do this, the child gear has to be twice the side of the parent gear. I counted the gear pegs to see the size of the parent gear, and then I multiplied it by two. My parent gear had 16 pegs and my child gear has 32 pegs.RGB_LED.mp4RGB LED
I searched online for RGB LED coding, which I found on many different sites including the Arduino page. Jason Lin helped me with this. I then edited the coding slightly, with Jayden Causey's assistance. Although it goes red-blue-green, it transitions smoothly and the colors are bright. It took me several different tries and google searches to find out where the wires went on the arduino.final_5d93f089ba54b60013b59082_650944.mp4Gear Box #1
For this assignment, the parent gear had to rotate the same direction as the child gear. To do this, you had to have a gear in the middle, to go the opposite direction. I chose a gear with 24 pegs.servomotor.mp4Servo Motor
I was able to get a servo motor to rotate left and right. I searched online for code, and I ended up using the "Sweep" Code on the Arduino Website. To get my lights to change at the same time, I had to go into the code and edit some of the pegs.
Laser Cut Name
I laser cut my name into cardboard after Ms. White gave me a tutorial. I made my name negative space and had Ms. White check it before I pressed start. I then went into the scrap cardboard box to get a piece big enough. It was done cutting in less than 30 seconds. Once I took it out, I punched out the cardboard holes.pumpkin.mp4Laser Cut Pumpkin w/ LEDs
This was the constraint that took me the longest. We created a simple pumpkin on InkScape, and then transferred it to a USB stick. We cut our pumpkins using the laser cutter, and then cut the sides of our pumpkin using an X-ACTO. Next, I coded the LEDs using an Arduino, and wired them into the back of the pumpkin. The lights change from red to green to orange.
Moire Sketch #1
I created my moire sketche with the outline Ms. White gave us. I chose to do an organic design with many circles and curves. It is based off of a mandala or snowflake.
Moire Sketch #2
I created my moire sketch with the outline Ms. White gave us. I chose to do an organic design with many circles and curves. It is based off of a mandala or snowflake.
Laser Cut Servo Mount
I created my servo mount on InkScape with the help of Chanel. I took the dimensions of my servo motor, and then cut out the appropriate holes. Then, I uploaded it to a USB stick and loaded the design onto the laser cutter. Lastly, I punched out the excess cardboard.gears.mp4Gear Box #2
I created a second gear box, with both parent gears and child gears that have to move in opposite directions. My friends, Aleks, Caitlyn, and Myah, helped me outside of class to complete this benchmark.
Moire Sketch #1 on CAD
I decided to create my CAD sketch on Solidworks. I chose to use this program because it was what I was most comfortable with.
Moire Sketch #2 on CAD
I decided to create my CAD sketch on Solidworks. I chose to use this program because it was what I was most comfortable with.gears.mp4Arduino Controlled Servos & LED
I had to create two servos and one LED controlled by an Arduino. I had to get a lot of help from table 5 and 6. I wired the two servos together, then wired it to the arduino. For the LED, I plugged it into a bread board, which then hooked up to the motherboard.
Cardboard Prototype Cutout
Ms. White gave us 6 different documents to cut out on the laser cutter. These documents were pre-designed and we didn't have to do much, other than supervise. After they were done, we punched them out.
Moire Sketch #1 Laser Cut
I uploaded the moire sketch I created on Solidworks, to a USB. Then, I uploaded the document onto the laser cutter's computer. After it is finished cutting, I punched out the holes.
Moire Sketch #2 Laser Cut
I uploaded the moire sketch I created on Solidworks, to a USB. Then, I uploaded the document onto the laser cutter's computer. After it is finished cutting, I punched out the holes.gears.mp4Functional Prototype
Using the Cardboard Prototype Cutout, I created a functional prototype. To do this, I had to expand the Solidworks file, and get a lot of help from classmates.
Code
This code makes sure that the servos rotate independently and the lights blink other than RGB. #include <Servo.h>Servo myservo1;Servo myservo2; int redPin = 11;int greenPin = 10;int bluePin = 9; //uncomment this line if using a Common Anode LED#define COMMON_ANODEvoid setup(){ myservo1.attach(8); myservo1.write(90); // set servo to mid-point myservo2.attach(7); myservo2.write(90); // set servo to mid-point pinMode(redPin, OUTPUT); pinMode(greenPin, OUTPUT); pinMode(bluePin, OUTPUT); }void loop() { myservo1.write(0); // set servo to mid-point delay(1000); myservo2.write(0); // set servo to mid-point delay(1000); setColor(255, 0, 0); // red delay(1000); setColor(0, 255, 0); // green delay(1000); setColor(0, 0, 255); // blue delay(1000);}void setColor(int red, int green, int blue){ #ifdef COMMON_ANODE red = 255 - red; green = 255 - green; blue = 255 - blue; #endif analogWrite(redPin, red); analogWrite(greenPin, green); analogWrite(bluePin, blue);
Solidworks File
Ms. White gave us this solidworks file to use as a reference. We could expand it to view the inside.20191212_082840.mp4Presentation
This is what I presented in front of the class. We had to include our LED's blinking colors other than RGB, and Our servos had to go opposite directions at different times. The right servo drives the back moire, while the left servo drives the front moire. My friends helped me with the coding for this. The most challenging part of this project was the construction and coding. My favorite process was the design and laser cutting. I really like the creative process and problem solving.The purpose of the functional prototype is to test our design and see if our coding will be good for our final sculpture. Cardboard was a difficult material to use because it is flimsy and bends/rips easily. I am very excited to start using stronger materials because I think it will turn out nicely. I would change the servo mounts because we are supposed to use 3, but I could only fit 2 when I create the prototype. Also, I would change the frame around the moires, because they tended to scrape up against each other. On the solidworks file, we will have to expand it, change it to 2D and change the power settings so that the laser cutter will cut the wood easier. I will change the moire so that my kinetic sculpture has its own personality. We will also have to use acrylic in come places, where we previously used opaque cardboard. can't wait until we can build the final Kinetic Sculpture!
Install Servos
I disconnected the servos from my prototype, and I reinstalled them on the plexiglass. We used small screws to hook it onto the plexiglass, so that the movement of the horns wouldn't knock itself off.Cut out Moire 1
I cut out my first moire using the glowforge. I had to transfer my ".dxf" file, to an ".svg" file. Ten I uploaded my file to google classroom. Then, we uploaded it to glowforge.com and pressed the button on the machine.Cut out Moire 2
I cut out my second moire using the glowforge. I had to transfer my ".dxf" file, to an ".svg" file. Ten I uploaded my file to google classroom. Then, we uploaded it to glowforge.com and pressed the button on the machine.20200130_154648 (1).mp4Install and Solder LEDs
I installed and soldered my LED'. I made sure that I had all of the same grounds, red, blue, and green pins. I had only one setback, but it ended up being the biggest. My two old LEDs were a different type so I had to take them out.
Installed Arduino
I installed my Arduino by drilling holes into my acrylic and then screwing them into place. We used machine screws.servos.mp4Moires Independent
I combined several different code to create the perfect code. I edited it to the way I wanted. I glued my front moire and my small gear to the center shaft. Then, I glued my back moire to my big gear.rainbow_rgb.mp4Three Light Patterns
I created my light patterns by using the basic rgb, and then faded the lights. My lights go in the pattern: red, yellow, green, aqua, blue, purple, white.
Three Layers of Acrylic
I assembled my three acrylic layers by using a 5" dowel. I hammered it into my last layer to wedge it into place. Then I covered the holes up with a finishing trim. The dowels aren't glued in place for security reasons.20200227_081703.mp4Servos do three distinct patterns
I coded my servos to do three distinct motion patters by including the servos directions throughout my LED patterns. My child gear/servo goes left, closely followed my my parent going right. Then both rotate left. Then the parent goes slowly to the right.; then fast. This pattern repeats.
Finish the sides
First, I got two pieces of trim from Ms. White, that had been cut out with the glowforge. Chanel and I took our pieces outside and spray painted them black. Once they were dry, they were able to be installed. I super-glued my trim pieced to the side.20200227_081703.mp4Final Kinetic Sculpture

Captain Safety
Captain Safety
While we wait for our acceptance into the MIT grant, we chose to focus our attention onto a smaller, practice project. Due to this year's pandemic, we came up with a social-distancing 'Captain Safety'. This tiny machine detects how close the user is in relation to another person. As you get closer(less than 6 feet) the smiley-face:) turns into a sad face:(. Our main materials for this project were the Arduino-Nano, 8x8 LED Matrix, breadboard, wires, and Ultrasonic Sensor.
Getting Acquainted with Materials
During our seventh week, we started our 'Captain Safety' project. In order to be able to succeed, we needed to get acquainted with the materials included in our packages; the first week of school, we were given packages so that we could still do engineering from home. Inside, we received male-male & male-female jumpers, aa batteries, battery packs, a breadboard, a perforated prototyping board, an ultrasonic sensor, an Arduino Nano, 3 header pins, an 8x8 LED Matrix, an 8x8 Neopixel LED array, a ATTINY85, a USB cable, and wire. For this project, however, we will be mainly using the jumpers, breadboard, Arduino Nano, ultrasonic sensor, 8x8 LED Matrix, and the USB cable.
Practice Circuit Picture
This is an example diagram from Tinkercad.
This resource covers how to solve pin configuration issues, as well as the features and specifications of the LED Matrix. In addition, this site shows great in-depth diagrams and blueprints.
Arduino NANO + LED Matrix 8x8
This short videos goes over how she has set up her 8x8 LED Matrix and how she controls it. There are several resources, for coding applications, demonstrated in the video, as well as close up shots of the technology(pins).
This resource is a conversation board where people can help each other with technical issues. This particular board covers the 8x8 LED Matrix on an Arduino Nano.

This, slightly longer, video goes into further detail of working with Ultrasonic Sensors, teaching the viewers more advanced coding techniques.
20201018_223546.mp4Functioning LED Matrix
After several weeks of struggling with my 8x8 LED Matrix, I had a breakthrough and was finally able to create shapes. My personal computer is a chromebook, but it turns out you are only able to upload code onto an Arduino with either a PC or Macbook.
Functioning Ultrasonic Sensor
After unhooking my LED Matrix, I used this source -click here- to make my Ultrasonic Sensor work.

Weekly Updates - 1st Semester - 2020
Week 1
August 3-7The first week we got back to school was purely introduction to the class and getting back into the swing of things. We troubleshooted technical issues with virtual learning and we went over information regarding the InvenTeam process. At this point, everyone that came to the meeting was either on the InvenTeam or they volunteered to help with the idea process or construction.
Week 2
August 10-14Around this time we started to become better with our daily virtual-schedules and we devised a plan on how to brainstorm ideas for inventions. After deciding that we did not want to create a new bike lock, we created a Coggle (a web program the multiple people can edit on at a time). The map above is an example from our Systematic Racism Coggle. It includes color-coded ideas from each of our team-members.
Week 3
August 17-21Week 3 consisted of more brainstorming and fleshing out our favorite ideas. After presenting our ideas to our classmates and peers, we pressed on with our decision making. Invention brainstorming included researching, finding statistics, probability of being able to invent it, and figuring out the beneficiary. We honed in on roughly 15 to 20 ideas and then were given three votes each.
Week 4
August 24-28Thru collaboration and individual research, we formed our InvenTeam Application. For collaborative research, we joined extra Zoom meetings and then were placed into 'breakout rooms'. Each of us were instructed to write a specific part of the invention statement and InvenTeam Application for Lemelson-MIT.
Week 5
August 31 - September 4After choosing our focus for the InvenTeam and filling out our application, we all collaborated to create our Background Research. Then, we were each given a passage of text to recite while filming. Subsequently, we uploaded each our our clips onto our shared Google Drive, where Alexandria G. pasted them together into one single video.
Week 6
September 7-11While we only had one class this week due to labor day, this week was filled with documentation of the past couple weeks.
Week 7
September 14-18This week, we got acquainted with our materials and got ready to work on our Captain Safety project. After making a clear transition to explain, to the reader, why we are changing projects, we took a picture of all of our parts. Then, we labeled our photograph to help with the construction process. We added the photo to this website, along with a caption explaining the purpose.
Week 8
September 21-25During our eighth week, we started our project by researching our LED Matrix and joining together in group discussion. Needed in our portfolio, we each researched at least three different sources for getting our Matrix up and running. Although we researched independently, we were placed into breakout rooms to collaborate and share our findings. If one of us were able to wire and code our arduino, then we could help the others in our room.
Week 9
September 28 - October 2This week was entirely dedicated towards determining pin configurations and wiring our LED Matrix. Even though I was using the same sources as the rest of my class, my matrix still wasn't lighting up, due to a malfunction with the Matrix (scorched wires).
Week 10
October 5-9This week, we were given the assignment to research Ultrasonic Sensors. This is the key component to making our Matrix work; the sensor determines movement and how close you are. We even got to host a special guest, Toren's father - Mr. Mosley, who spoke to us about the police force and his opinions on the devie. He also offered us advice on how he would market the product and legal advice.
Week 11
October 12-16Continuing from the past week, we were required to have all of our Ultrasonic sensor research completed. Furthermore, we worked towards making our Sensors functional and usable. However, we only had one class this week, so all we were required to do was take a picture of our serial monitor readouts.
Week 12
October 19-23While working in breakout rooms, we helped our peers who hadn't yet gotten their Ultrasonic sensor up and running. We also filled out forms to get a collaboration grade. Besides finishing this small assignment, we were hosted by someone from the Lemelson-MIT InvenTeam organization. After congratulating us on our enrolment into the grant, he cleared up a couple questions for us and gave us some key points to follow for the project. He also let us know their current plans for EurekaFest at MIT.
Week 15
During our fifteenth week, we reviewed out team members' role pitches, on FlipGrid, and started our to fill out out a document with our chiches for who we think should fill each of those roles. On Wednesday, we announced the assignment of roles and then created a plan for working and learning over break. Ending our class on Friday, we shared our individual plans with each other.Week 16
After coming back from Thanksgiving break, we got right back to work. Over the break, I had countless problems with the tech we were trying to use. I only have a chromebook and a 12-yr-old Lenovo, which neither supported the programming that was needed. After picking up a PC from Drew Charter, courtesy of Tech Support, I was able to download Raspbian, and will, as of Dec. 7, be able to download Python and Pycharm.Final Application

Week 7
February 15-19This week we spent our time getting ready for our Mid-Grant Tech Review. On Wednesday night, we had a rehearsal where we presented our progress in-front of several representatives from Lemelson-MIT.
Week 8
February 22-26Monday night, we had our Mid-Grant Tech Review, a large presentation where we shared our progress with friends, family, and Lemelson-MIT.
Week 10
March 8-12While I was unable to join our Wednesday afternoon meeting, this was my first week back to School, going in-person on Thursday and Friday. On Thursday, our engineering class with Ms.White was asynchronous, and our assignment for the day was documentation. While Hybrid seemed to be a popular choice, only one other person was with me in my first period, Quinn.
Week 12
March 22-26This week we took SATs on Wednesday, but besides that, I got to re-enter the school building again for classes. On Thursday, I brought my Raspberry Pi into the school, due to some issues I was having while working at home. After researching and trying to remedy my problem, it was determined that there is something wrong with my micro-sd card. Because I am in the school building, I do not have a micro-sd card adapter, so I had to wait until I got home in the afternoon.
