Hospitals are currently exceeding capacity and strained for resources. Yet, in many cases, nurses and doctors must stay near patients to listen for alarms. Not only does this increase the exposure risk, it also further exacerbates the resource shortages.

While newer machines may support central telemetry, the majority of devices don’t. In addition, not only is it expensive to replace them, such a replacement results in substantial time costs from order processing, setup, and training.

Thus, this system was designed. It transmits audio signals from numerous rooms to doctors’ computers, decreasing exposure and also increasing efficiency while improving patient care. Now, each doctor can monitor many patients via a powerful web or desktop interface. At the same time, each patient can now be monitored by numerous doctors.

In the end, this system aims to provide cheap, reliable, and secure patient monitoring for hospitals. The device is scheduled to be tested in hospitals soon.

Applications:

• Rehabilitation (my friend recently tore his ACL, he hopes this will make physical therapy measurements less painful)
• Augmented reality control (the sensor sheet can be cut to a hand shape, sensing finger bending and contact)
• Sports monitoring (providing measurement of both posture and impacts)

Thank you to SAIL and mHealth for funding this project.

• Wearing a mask has been shown to reduce the spreading of disease
• Yet, many refuse to do so, even in crowded public areas
• Many businesses currently refuse service without a mask, but it is up to employees to enforce this
  • This setup leads to conflict and exposes employees to risk
• This API provides a free online endpoint that any service can integrate, providing a fast and effective AI-powered mask check
• Sample applications include in-app verification for delivery drivers, entry checks in brick-and-mortar shops, or even customer verification when calling a taxi
• Powered by TensorFlow and OpenCV

So many lectures are being held virtually right now. What if we could preserve and share them all?

Compatible with both iOS and Android, Vybe is a navigation wearable that aims to get you to your destination quickly and safetly – with no sounds or visuals to distract. Never again will you have to risk a glance at your phone while approaching a busy intersection.

Utilizing Bluetooth Low Energy and a custom haptics stack, we aim to make navigation both safe and intuitive.

Our company began at a hackathon, where we developed the initial prototype of the Vybe. After a big win there, we went on to interview at Y-Combinator and have not stopped improving on it since.

• Fully-programmable microcontroller created in Logisim.
• 16-bit ISA

• Given a particle’s initial position and velocity, the microcontroller was programmed to output the particle’s position over time if it were to collide elastically within a rigid container of a given size.

• Utilizes a custom 96-LED matrix arranged in an 8” tall cylinder
  • Prototype shown above, without wooden frame
• Drop a new piece… or flip a column or spin a ring
• Fast and fun, this project came complete with flowing animations
• Best of all, the matrix and controller were designed to enable full-board displays with only a few connections using persistence-of-vision tricks
  • You could make your own for a few dollars!
• Created with a team for the Columbia Art of Engineering Project Expo

Sporting an in-browser code editor, this game allows players to write their own algorithms to control agents which compete with one another in weekly challenges. Rather than competing for the highest score as with many algorithmic competitions, instead the agents are free to interact with, aid, and sabotage one another.

Designed to work alongside a course at Columbia University, this series of exercises was designed to show the speed of new browser technologies such as WebAssembly and WebGPU relative to traditional methods such as JavaScript and C.

Examples currently include linked list traversal and matrix multiplication.

Developed as a fun and fair game to play with friends and strangers around the world, Peww began as a simple top-down game and has been evolving ever since.

Utilizing the Spotify API, this website crafts a playlist of songs for you based on a single phrase and optionally a list of genres. There’s no way I’m the first person who’s wanted to listen to a playlist about “chicken nuggets”.

• Features a grouping system so you can meet new friends while talking to people you already know
• Accessible via Android, iOS, or web app
• Powered by Node.js, React Native, Socket.io, and WebRTC

• Utilized inertial sensors to perform dead reckoning
• Costs under $20
• Designed as an attachment compatible with standard pens
• Prototype video

While many educational institutions rely on a long list of services to enable virtual instruction, this system aims to combine all of those technologies in one place.

Features lecture recordings, video meetings, assignment submission, customized online worksheets, and more.

Traditionally, an autonomous routine for a VEX robot is carefully planned, implemented, and tuned over the course of several days. However, some teams may not have the programming skill or time to do so. More importantly, even the most skilled programmer can’t develop a perfect routine without any testing in the midst of a competition.

This system allows a human driver to control the robot via a controller, recording the user’s actions. Then, during competition, the routine can be played back, recreating the motions via precise control systems utilizing PID controllers, velocity measurements, voltage readings, and sensor values.

The system can been exceptionally useful for designing an autonomous routine to synergize with an alliance’s strategy or to foil an opponent’s plans.

Developed to aid in the college essay brainstorming process, this website serves as a simple tool to craft essays on. With the necessary metrics upfront and no distractions, users are able to experiment with essay ideas. They can also leave and take a break – when they come back, their essay will be waiting for them thanks to local storage capabilities.

SpecPlanner seeks to help facilitate the care of children diagnosed with Autism Spectrum Disorder (ASD). It provides a streamlined calendar-esque tracking interface which allows parents to keep records of good and bad behaviors.

Place two hands in the air and play away. By moving your hands and bending your fingers, you can play a five-octave piano as if it were right in front of you.

Note: Leap Motion sensor required.

Designed as a free alternative to expensive gaming consoles, users can use a computer as the display while controlling the games from phones or tablets.

Note: The hosted version is set to always run a snake game. Make sure you have at least one “display” and two “controllers” connected – either on separate devices or separate tabs.

• With the closing of schools around the world, many are missing out on yearbook signing – a chance to share lasting messages with the people they’ve gone to school with for years.
• While some solutions exist, they rely on cumbersome login and account creation systems.
• YRBK.live is designed to be quick, secure, and registration-free. Via the usage of unique URLs, students can share their page so anyone can leave a message in an instant. Yet, only the owner can view these personal messages.

Winning a prize from Project Green Challenge, this website speaks about the dangers of air pollution with smooth scroll-based animations.

Created as a way to practice with my Quiz Bowl team, this website allows anyone to join a room with a computer or mobile device. Then, users can buzz-in at any time, with the earliest buzzes displayed to all.

Note: make sure you have at least one “display” and one “controller” connected – either on separate devices or separate tabs. The initial load time may be slow, as the system is hosted on a free Heroku dyno.

Pick a song and watch them move. Drag the heads to have some fun, or relax as these virtual bobbleheads move with the music.
