1. John Wloch Wind-Aid Preliminary Design Review 8 April 2008 Andy CrutchfieldJames Gates Keri Macaulay David Rupp

2. Current Status – On Schedule Prototype assembly completed Prototype testing ongoing Wind-Aid Show Stoppers: Last week: high startup generator torque None at this time We are on schedule, per group and class project timetables

3. Wind-Aid High Startup Generator Torque 36 V with open circuit 10 ohm resistor, 10-20 V, 20W achieved Sustained power Last Week—Show stopper found

4. Last Week Action Item 1: Completed initial documentation Documentation handed in on CD All necessary graphics have been completed Action Item 2: Electronic Circuits and Coding Multiple preliminary circuits created Final circuit started with focus on Tachometer Tachometer code near completion Wind-Aid

5. Next Week Action Item 1: Further Prototype Testing Gather more information Test advanced circuits Wind-Aid Action Item 2: Electronic circuits and coding Finish coding for Tachometer Finish constructing complete prototype circuit
