Designed and developed smart public telephone products. Modified the firmware of an inkjet printer to convert it into a two axis printer. I also worked on the mechanical design and constructed prototypes. Created a Visual Basic program to acquire data from eight vacuum chamber instruments through serial communications ports and create an output file for import into spreadsheet. The program provided inputs for sample rate and the duration of the experiment. Required learning and working with multiple proprietary protocols and various serial standards.

The module can also control outputs to valves in response to input conditions. Developed a Windows product for an insurance company to replace their DOS product.
