The Honors project is potentially the most valuable component of an Honors education. Typically Honors students choose to do their projects in their area of study, but some will pick a topic of interest unrelated to their major.
The Honors Program requires that the project be presented at a poster presentation event. Poster presentations are held each semester. Most students present during their senior year, but may do so earlier if their honors project has been completed.
This site presents project descriptions and selected posters for Honors projects completed since the Fall 2015 semester.

Abstract
The oven used by Team PrISUm to conduct composite materials testing was controlled by a system that is complicated and lacks several features that the team finds desirable. This project aimed to create a replacement control system using a raspberry pi as the controller hardware and Python 3.4 as the programming language. A traditional proportional-integral-derivative (PID) controller was created, with improvements adding resistance to integral windup and derivative kick. The hardware required to support the PID controller was identified and assembled onto a custom circuit board to simplify the equipment setup. A web interface was created to eliminate the need for a workstation connected to the oven. The web interface provided easy access to the temperature profile programming and operation of the oven. The Python language allowed for quick development and testing while adding new features such as data logging. Overall, the new system provides a more stable platform with several new features not previously available.
