As part of my first year in Rocket Project at UCLA, I created and lauched a solid motor rocket with a small team. The goal was to carry an egg to apogee and return it undamaged.
We were the only group to successfully protect the egg. Part of this was due to our design choice to flare out the nose cone which provided more room for cushioning. My primary contributions were in designing the nose cone and ensuring that the overall system fit together. I learned a lot about rocket design in general and gained experience using CAD.
For a summer project, I decided to make a macropad (small keyboard). The goal was to create small device which I could use for media and volume controls.
I designed, 3D printed, and hand soldered the macropad. I also worked with the Arduino IDE to program the controller for the macropad. I familiarized myself more with 3D printing and learned a bit of circuitry to finish this project.
As part of my programming with MATLAB class, I created a program that models an epidemic. One part of the program used differential equations as the model, but the portion shown above used random walking to simulate the epdiemic. For context, "S" represents susceptible (uninfected) people, "E" represents exposed people, "I" represnts infected people, and "R" represents recovered people. Using the program, I was able to analyze the effectiveness of lockdowns and preventative measures based on start time and strength.
This program was the culmination of all the coding skills that I had learned in the class.
