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

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