Brew-Bot is a high functioning drink dispenser that has the ability to perform various tasks as it dispenses each drink. It is able to detect when a cup is placed in front of it and dispense nine different drinks, using up to seven ingredients, with or without ice, and plays music while you wait. A homemade ice dispenser created from a cooler, a DC motor, and custom designed and 3D printed agitators and auger drums were used in conjunction with the rest of the cart to dispense ice for a set amount of time while the drink was being made. An LCD display located on the icebox serves to notify the user when the ice box needs more ice. Additionally, Brew-Bot has also been programmed to rinse out the manifold before the start of and at the end of each drink. The user interface is simple as a number one through nine being selected on a keypad to tell it which drink you would like, and a master reset button has been provided in case of any error that occurs during the dispensing process. Ingredients for the drinks are located at the bottom level of Brew-Bot, and the use of highly accurate peristaltic pumps help dispense these fluids to the manifold which leads to the user’s cup, providing them with their drink. While the drink is dispensing, music plays for the duration and an LED indicator light is used to tell the user when the drink is at half way full and then complete. The entire system is run off of three Arduinos using integration through I2C serial communication.
The images show the overall design of the product from the front and the back. More details can be seen in the Overview and Demonstration video above. The attached design report contains code used, wiring diagrams, flow charts, project requirements, and various iterations of each component throughout the design process.

For my Engineering II Design course, we had a semester group project where we had to design, develop, create, and compete with a semi-autonomous submarine. We were given competition constraints that included being less than 23 cm x 15.25 cm x 12.5 cm, submerge itself 61cm, travel 4.5m, and be initialized with one action to run the course of the competition.
We modeled and 3D printed custom parts for our submarine, which included space on the inside for our battery packs, motor housing, and wiring for all components. On the outside, we had adjustable dive planes, 2 motors, and a simple water-proof on/off switch. The idea was that it would begin positively buoyant then the dive planes would allow it to travel to the desired depth.
Throughout this project, I learned lessons that ranged from how to best go about the design process and how to work with a team that does not contribute. We found that, from the beginning, much more research could have been done and more design iterations should have been completed before moving on. If given more time, we would have designed the body to contain much less air in the center so it would have a better ability to dive. Additionally, we would have added a ballast system and employed an arduino and a single propeller instead of two in order to have better autonomous control/adjustments of the submarine after initializing it. I also learned how best to work with/accomodate for a team that does not contribute. While this was unfortunate and contributed to the quality of the device, it did give me the opportunity to learn more skills I would not have had the chance to learn if not for needing to pick up more responsibilities. I acted as co-project manager with another group member and we headed the design, electronic, assembly, and testing aspects of the project.

As part of the Engineering I Design course, our final project was to create a detailed surface model of an object. For my project, I chose to model my computer mouse. Throughout the course, we learned the basics of SOLIDWORKS working with solid bodies and self-learned surface modeling. From the model we had to create the product sheet for our designs. Since completing this course, I have utilized both solid and surface modeling for all of my projects to 3D print and bring our designs to life.

During the last semester of my senior year of high school, we conducted group research projects as part of my Honors Nanoscience course. My partner and I created an antibacterial spray to prevent the growth of bacteria on the reeds of musical instruments. Given that we were both musicians, we had a lot of background knowledge that allowed us to have a greater understanding of how to best approach the problem. Reeds are stored in instrument cases after use, which tend to be warm and damp, giving an ideal environment for bacterial growth. Many musicians can get sick from the bacteria if their reeds or mouthpieces are not properly cleaned or replaced, and can re-infect themselves by continuing to play on the same parts. Our solution was to use a combination of antibacterial essential oils and colloidal silver as a spray to be applied before storing the reed to prevent bacterial growth. We went through many iterations of testing different oils and combinations of oils to see which would prevent the most growth on an agar plate, which contained samples swabbed from the mouth of a woodwind musician. We recorded samples of the musician playing on a reed with and without the spray and were able to ensure the solution did not affect the quality of sound of the instrument.
At the end of this project, the class had a poster session where we presented our research and product to scientists, teachers, parents, students, and faculty. The scientists we presented to voted our project the most likely to be implemented immediately. Shown above is the poster we presented with a summary of our research and processes.
