Senior Design 1 Team Shortnose Sucker: Project Auto-Shifting Bicycle Team –Tim Slevin-Vegdahl (Fall Team Lead) –Joan Javier (Spring Team Lead) –Cyrus Medrano –Brendan Figuly University of Portland School of Engineering Advisors Dr. Robert Albright Dr. Peter Osterberg Industry Representative Mr. Walter Harrison

Senior Design 2 Introduction Design a device that will automatically shift the gears of a bicycle Benefits new bicyclist and people who do not know how to properly shift gears on a bicycle University of Portland School of Engineering

Senior Design 3 Scorecard University of Portland School of Engineering Mount magnetic sensor onto bicycle after verifying functionality Debug Macro Model so we can compile and burn our CPLD Complete actuator to be functional (get motor running off CPLD)

Senior Design 4 Testing CPLD University of Portland School of Engineering

Senior Design 5 Additional Accomplishments Motor Prep and mounting bracket acquired Clock circuitry is complete University of Portland School of Engineering

Senior Design 6 Plans Mount sensor on bicycle Complete a working Plan C controller Complete first draft of Final Report University of Portland School of Engineering

Senior Design 7 Testing Magnetic Sensor University of Portland School of Engineering

Senior Design 9 Concerns/Issues MOSIS chip will not be here for Founders Day and the current backup does not function to the specs we need. We will need to make a Plan C controller. Our schedule will be behind on the actuation because we need a driver for the stepper motor. University of Portland School of Engineering

Senior Design 10 Reprogramming CPLD University of Portland School of Engineering

Senior Design 11 Conclusions The CPLD backup not working is causing major problems The sensor is ready to be mounted on the bicycle University of Portland School of Engineering
