1. MINI BAJA

2. Mini Baja goals  Modular suspension  Concept  Analysis  Rebuild of rear frame  Automated transmission  Air shifting system  Implementation of electronics

3. Modular suspension  Bolt on hoop design  Symmetric about the center of car  Installation in less then 20 min

4. Analysis on suspension  Deflection testing  Finite element analysis  Bolt selection

5. Frame changes  Narrow the frame to account for added hoops  Add brake to center shaft  Create space for air components

6. Air shifting system  Air compressor  CFM  Battery  Air tank  Size  Weight  Cylinders  Shifting  Clutch

7. T.C.M. – “daughter board”  Sensor Signal Preparation  User Input Recognition  Output Signal Conditioning  Upgrade Ready Design Circuit boards provided by PCB Fab Express

8. Modern Device’s Arduino Clone  Self-Contained Microcontroller Main Board  C++ Derived Programming Code  10 bit Analog to Digital Converter  14 Digital Input / Output Pins  6 Analog Input pins

9. Conclusion

10. Conclusion continued  Suspension operated as expected  Air components shifted transmission in manual testing  Electronics had errors and failed upon initial testing  Causes of failure are: Electro-Static Discharge Unforeseen components needed
