Team Shortnose Sucker: Project Auto-Shifting Bicycle

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

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

3. Scorecard • 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) University of Portland School of Engineering

4. Testing CPLD University of Portland School of Engineering

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

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

7. Testing Magnetic Sensor University of Portland School of Engineering

8. Milestones University of Portland School of Engineering

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 aPlan 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

10. Reprogramming CPLD University of Portland School of Engineering

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
