Wireless Price Display System

This project was my final team project for "Electrical Engineering Laboratory 3" class in 2004 (when I was junior in college). The goal was to make a wireless system that substitutes price tags with electrical displays in grocery stores. The base station manages a list of products in the database, and it sends out price information to receiver units. Receiver units are simple character displays having unique IDs. When any products' prices change, the system can easily update new prices on these displays. 

Drupal Course Management Module for UMD Websites

This project was designed to provide most up-to-date courses information to University of Maryland College of Arts and Humanities (ARHU) websites. Since most ARHU websites were implemented with Drupal (Content Management System), a Drupal module was developed to migrate the university's course catalogs into Drupal databases. For crawling the course catalogs, Brady Law (CS student)'s Python scripts were modified and re-implemented.
