EE/CS 481 Spring 4 EE/CS January, 2008 University of Portland School of Engineering Scorecard Tasks Completed: Completed Design Review Measured and recorded output information from UPS Ordered parts Shortcoming(s): Complete circuit design and simulation Team Merlin was not able to complete circuit design, but will be finalizing the circuit and its components this week. This was due to the fact that emphasis was placed on completing some sort of simulation using PSPICE, B2Spice, etc. However, they have been advised by there advisor to start building and not worry about simulation at this point.

EE/CS 481 Spring 8 EE/CS January, 2008 University of Portland School of Engineering Concerns/Issues Behind schedule Solution: Keep focused and commit the team to the deadlines specified. No other choice! Building without having done a complete simulation - Could not simulate using software such as PSPICE last semester and during Christmas Break. Advised to stop simulating and start the building process as simulation will take too much time. Solution: Extra safety/careful verifications of numbers/values

EE/CS 481 Spring 9 EE/CS January, 2008 University of Portland School of Engineering Conclusions Design Review Approved AIR-X put together (Stand and device interfaced) Ordered Parts Plans: –Theory of Operations 0.9 –Finalize circuit design –Build battery bank –Construct and test design (circuit) –Receive all the parts ordered Many changes have occurred with ‘Milestones’ and therefore, no choice but to keep to those deadlines Any Questions?
