In 2010 I was part of an Engineering Design course. During the course our group was requisitioned to take an electric toothbrush and design a way to improve the system. The project page that was created can be found in the link below.

Additionally our team was asked to design a power generation “hut” that would be able to supply steady power in areas that have temperamental or non-existent power grids. The link to this project page is below

Finally as a final project I used SolidWorks to design Lego blocks and have them “build” a tower by animating the Lego blocks so that they snapped together as real Lego’s would. The link for this project is found below.
