5. Problem Statement • GeneralBackground • Convert current EE lab to ELVIS • Document the conversion process

6. Problem Statement

7. General Solution • Redo EE 201 labs • Write instructions for students • Find volunteer to follow the instructions • Develop new interfaces • Test • Document the conversion process

8. Operating Environment • Standard laboratory condition • Indoors • Clean air • PC with Windows

9. Intended User and Uses • User • Instructors or TAs who intend to use ELVIS in their circuit or electronics labs • Uses • Help users with conversion process

10. Assumptions and Limitations • Assumptions • ELVIS bundle from NI in working condition • The group can create virtual instruments that are not provided • Limitations • No current or inductance measurement capacity • Measurement inaccuracy • Limited knowledge of internal design

11. End-Product Description and Deliverables • Selected labs will be converted to ELVIS system • New instructions for selected labs • Documentation of conversion process

12. Present Accomplishments • Familiarity with ELVIS hardware and software • Carried out EE 201 labs 1, 5 and 6 with the ELVIS system • Produced new documentation for completing EE 201 labs 1, 5 and 6 with the ELVIS system

13. Approaches Considered and Used • Considered • Creating new virtual instruments • Individually converting every lab for use with ELVIS • Used • Decided to use Virtual Instruments provided by NI for their ease of use and functionality • Focused on key labs which made use of different features of ELVIS

14. Research and Design Activities • Research • Read National Instrument’s ELVIS manual • Researched how others are using ELVIS • Design • Updated labs to make use of unique capabilities present in the ELVIS system

15. Implementation Activities • Took notes as we implemented several EE 201 labs using ELVIS • Created new lab instructions for the labs that could be completed with ELVIS

16. Testing Activities • Asked a EE major to follow our new lab instructions • Asked a ChemE major to follow our new lab instructions • Reviewed our own instructions to ensure completeness • Tested the accuracy of ELVIS

17. Test Results

18. Personnel Effort

19. Financial Budget

20. Project Schedule

21. Project Evaluation • Analyze necessary virtual instruments (100%) • Completion of virtual instrument interface (100%) • Completion of necessary documentation (100%) • Completion of testing (100%) • Revision (100%) • Working demonstration of ELVIS (100%)

22. Closing • Commercialization • No commercial application • Used by ECpE department • Additional Work • Re-evaluate ELVIS using non-prototype unit • Lessons Learned • Time Management • Team Communication • Risk Management

23. Summary • Project Goals • Evaluate ELVIS for ECpE • Document conversion process • Approach Taken • Utilize tools provided by NI • Preserve educational concepts taught in lab • End Result • Sample of EE 201 labs • Conversion documentation
