The design team consisted of two members: Kire Filipovski (E.E.), and Mike Schwankl (C.P.E.). Most of the design was a joint effort, but there are some tasks that were assigned separately. The division was based on previous experiences as stated in our resumes in Appendix A. The majority of the computer interfacing was done by Mike Schwankl, and the bread-boarding was done by Kire Filipovski. The complete design management is summarized in the Gantt chart shown in figure 1.

2.2 Cost Analysis

In designing and testing the module there was little help from resources at Villanova. Our entire module's parts were imported, with the exception of minor analog parts such as capacitors and resistors. Three samples of TMS320AV120FN were ordered from Hamilton Electronics in Phoenix, Arizona which were $17 each plus $5 shipping. Mr. Harris, a part-time teacher who works for Phillips was able to provide us with three samples of TDA1305T DAC for free. The cost per DAC would have been $5. When interfacing the two chips we needed IC adapters which would make it possible to connect them to a Type-A bread-board (0.1"x 0.3" grid). The adapter for the TMS320AV120FN was $32, and $16 for the TDA1305T adaptor plus $5 shipping. The remaining minor parts of the module are estimated at $8. The total cost for this initial module in parts was $78. However, the cost of the parts for a finalized product would not include the IC adapters reducing the cost to $30, with possibility of further price reduction when using large quantities. The labor costs were estimated with an average beginning engineer's salary of $17 per hour (35k/year). With this figure and an average of 20 man hours a week times the 10 weeks of this semester our team worked, the estimated salary expenditure for the project would be $3400. The price for a commercial production of this project is hard to estimate because of the equipment necessary to produce a professional board etching is unknown. However, a close estimate of less then $60 per module is realistic for the final product.
