Senior Design Project 2018: The purpose of this project was to build a toothbrush simulator to be used by toothbrush, toothpaste, and other dental companies. Solutions similar to this exist on the market for approximately $40,000. With 3D printed parts, ours was built for under $200. The simulator actuates the toothbrush vertically, and has the platform with the sample actuate horizontally to create an elliptical brushing pattern.
This was built with the help of Richard Ding, another Mechanical Engineering student at Tufts. This prototype uses an Arduino to control the lighting effects of the table. Players spin the pirate ship wheels to generate electricity to power the lights themselves. The faster they spin, the faster the lights race around the table. This continues until a winner is declared.
The infinity table was built as part of a PowerPlay prototype, and was tested on children at the Center for Engineering Education and Outreach at Tufts.
This steel contraption was made with the help of Conor Ward, a former SMFA student at Tufts University, and Richard Ding, a Mechanical Engineering student. The steel sheets were cut to size and then welded together. Programmable LEDs make up the "rungs" of the helix, and are powered by an Arduino.
Users can spin the wooden wheels on the side, or the cranks, to queue a light sequence animation on the helix.
Sonos speaker company hosted a design challenge at Tufts University. The prompt was to "build something to enhance the daily moments in a person's life". My team consisted of Thomas Coons, Eric Chen, Fabio Vera, and Zack Nassar (all engineers at Tufts). Together, we built an app that is integrated with Sleep Cycle. Users can set an alarm time, and a Raspberry Pi will send a signal to the Sonos speaker to begin playing music when users are the "most awake".
We placed 3rd in the competition, and received free Sonos speakers as our prize.
This project was built so that I could open and close my curtains, and turn on and off my lights using my iPhone. iPhone is connected to a bluetooth module which is connected to an Arduino MEGA. The Arduino controls the stepper motor to determine how much light the curtains should let in, and it also controls a an electrical box through a relay so that the lights can be switched on and off remotely. It also includes a humidity and temperature sensor; all of the data and controls are done through the Blynk App
A public art installation with a theme of Impermanence. I built a smart mirror using leftover parts from previous projects; anyone within sight of the mirror is encouraged to text one word to describe how they are feeling at a particular moment. A word cloud of all those emotions is created in realtime and displayed on the mirror. After every 50 responses, the word cloud deletes itself; demonstrating the impermanent nature of our thoughts and feelings.
Built in January 2018; this is powered by an Arduino which control four separate motors running on 12V. It is pre-programmed with a home-made recipe containing sake, iced tea, orange juice and apple juice. Control the bot using your bluetooth enabled smartphone!
Future iterations will include more motors that are run on more power so that the app can create multiple different drinks, or have users create their own drinks. The frame will also be redone: 3D printed to ensure a more snug and portable fit.
Home-made Alexa built using a raspberry pi, a usb microphone, and speakers. Built over Thanksgiving break 2017.
In order to run the program, three separate terminal windows need to be open on the Raspberry Pi: One to actively listen to audio input, one to run the Alexa service, and one to recognize the status of the "Wake Word"
