The following is a (dated) collection of personal engineering projects:
MIDAS: Dorm Room Automation
Dorm room automation system complete with a one-touch "party button." Internet of things implementation connecting several actuators and sensors to an internet-enabled automated controller.
Topics: IOT, automation, web services, voice recognition
MBTA Cryptography Security Analysis
Security analysis and cryptographic code breaking project where we found vulnerabilities in Boston's transit fare collection system. Utilized massively parallel computing infrastructure (FPGA-based), software defined radio, and custom data analysis software.
Topics: Cryptography, parallel computing, data analysis, computer security, software defined radio, FPGAs
Sana Telemedicine & Remote Diagnostics Platform
Open source platform to enable field physicians to collect health data and make informed decisions.
Topics: Telemedicine, remote diagnostics, image recognition, mobile apps, open source, workflow management
DARPA Grand Challenge Autonomous Car
Autonomous vehicle (AV) project where we used a combination of vision, LIDAR, GPS, IMU, relative ground sensing, and other sensors to self-drive an Acura MDX.
Topics: Self-driving, autonomy, sensor fusion, LIDAR, vision systems, Kalman filters
Self-Balancing Personal Scooter
Homemade self-balancing scooter made of electric wheelchair parts. Custom power electronics, control loop, and machined base.
Topics: Control systems, inverted pendulum control, power electronics, mobility
Echo Dome
Giant 4,500 RGB LED geodesic dome, with individually-addressable lights. Controller used 3D spatial sound over 5 3D speakers to coordinate custom light shows with the LED array. Built in Cambridge, and assembled in Black Rock Desert, NV.
Topics: LEDs, 3D sound processing, music visualization
Automated Water Fountain
Pond-sized recreation of the computer-controlled water jet fountain at the Bellagio Hotel in Las Vegas. Each water nozzle is individually controlled along one pivot axis, with on/off action and several controlled LED and halogen lights synchronized with the music.
Topics: Actuated hydraulics, motion control
Modernist Doghouse
Custom-welded modernist dog house. Design was Inspired by Piet Mondrian paintings and the Charles/Ray Eames house in Santa Monica, CA.
Topics: Metal fabrication, welding, painting, modern art
LED Light Wall
The LED light wall is a 24-watt, 8-section, digitally-controlled wall of light that can sequence through any color in the visible spectrum. It has several built-in animations and can also be controlled by a PC to sequence to music.
Topics: LEDs, music visualizations, power electronics, microcontrollers
