Fault Tree Analysis for a paintball gun that was created for a class project during the Spring 2009 semester at UB. Project goal was to recommend safety improvements for paintball guns (and paintball speedball fields to a lesser extent) to the ASTM sub-committee on paintball. Larger version of the fault tree is below for easier viewing.

Late to post online, during Fall of 2008 I worked on a group project for my Human-Computer Interaction course here at UB. The goal of the project was to evaluate and recommend design improvements for a Bluetooth Laser Keyboard which I had acquired from ThinkGeek.com. I decided to add it here because I was particularly proud of our prototyping setup.
