MPGuino (Arduino for Car MPG)

by

August 2009 This is an Arduino microcontroller that I wired into my car’s ECU and programmed to calculate the instantaneous/average miles per gallon of my 2002 Honda Civic. The circuit reads pulses from the Vehicle Speed Sensor and Fuel Injector wires. It is wired into my car via a USB cable. It’s pretty accurate once calibrated. My … Read more

IGVC Robot

by

July 2009 I competed in the 2009 Intelligent Ground Vehicle Competition, on the Georgia Tech RoboJackets Team. Our robot: Candi. I developed the computer vision algorithms to navigate an autonomous vehicle using only a vision camera. Our team ranked 6th place nationwide. Competition photos here. I wrote all of the vision and mapping code! The robot navigated using a single camera only. … Read more

Laser Projection Vision System

by

September 2008 A project at GTRI FPTD I worked on involving combining a color vision system with a 2D laser projector. Case Study about the project here:  Using Lasers to Identify Substandard Food. With Python and OpenCV, I got the system to find contours with the camera, and tell the laser to draw them in real-time. The goal was to … Read more

PIC Digital Speedometer

by

June 2008 I used a PIC microcontroller in a circuit to measure my car’s MPH. It measures the frequency of pulses from the Vehicle Speed Sensor, and converts it to miles-per-hour. A summer project involving programming a PIC micro controller to measure my Honda Civic’s MPH. The circuit I made measures the frequency of the pulses coming from … Read more
