  1. Dec0910 Science Center Hussain Almosa Karen Littlejohn Joey Nirschl Hassan Hassan Phase 3

  2. Problem: Our client is looking for additional interactive workstations that would demonstrate to the audience how the concepts from the Electrical and Computer Engineering (ECpE) Department curriculum at ISU solve real world challenges to assure a better and more sustainable future.

  3. Overall Design Requirements: • Operating Environment • Reasonable, stable temperature room • Stable environment • Open to public • Intended Users • Grade School age and up • Have limited to no prior knowledge about topics

  4. Overall Design Approach: Adding two modules to the Science Center in 1212 Coover • Piezoelectric Floor - To demonstrate that we can harness the mechanical energy from unconventional sources, such as people, in the form of electrical energy • Sequential Programming - To demonstrate and create more understanding of the concept of programming Room to promote interest in Computer, Electrical, and Software Engineering

  5. Dance Floor Idea: • Video

  6. Dance Power Block - Initial Concept:

  7. Dance Power Block - Revised Concept: We designed the Dance Power Block as a prototype and proof of concept for our application of harnessing mechanical energy through piezoelectricity. In the future, the block can be replicated to build a dance floor with different forms of display.

  8. Dance Power Block – Requirements: • The Dance Power Module shall generate enough current to power a small LED bulb. • The Dance Power Module shall support a weight of up to 200 lb. • The Dance Power Module shall be raised from the room floor. • Shall be visually appealing. • Shall be quickly understandable and easy to use.

  9. WiiProgramming – Concept:

  10. WiiProgram – Requirements: • Use latest version of Java Runtime Environment • Interface with a WiiMote • Only administrator users shall be allowed to configure the volume. • Shall be quickly understandable and easy to use without a demo. • Shall give the user a taste of programming.

  11. Project Risks: • Cost of piezo-generators too expensive • Piezo generator supplies insufficient power • Limited sources and literature on piezo-electricity • Bluetooth implementation with Java • Integrating WiiMote in with Java

  12. Proposed Schedule: • Spring 09: • Project Plan – end of Feb • Details and all parts picked out – end of Apr • Parts ordered – end of semester (May) • Fall 09: • Prototype built and working – middle of Oct • Testing and refining – start of Dec

  13. Dance Power Block – Design:

  14. Dance Power Block – Design Details: • Clear Lexan Case – supports up to 200 lb • Compression Subsystem – transfers mechanical energy to generator • Piezo Generator – supplies power to display • LED Visual Display – enables user interaction • Electrical Circuit – modulates voltage to safely power LED

  15. Dance Power Floor – Testing: • Structural Analysis for support of stresses on floor • Safety analysis • Analysis of circuitry for voltage and current produced • Experimental User Interaction

  16. Dance Power Floor – Results:

  17. WiiProgramming – Design:

  18. WiiProgramming – Design Details: • Background code to parse XMLs • GUI code to display to user • XML to store Program Options • XML for each available program on the module • GlovePIE program running in the background to convert WiiMote Input into Mouse controls

  19. WiiProgram – Results: • Have the program working • Had to change our design a little bit to get WiiMote Input working • Can interact with the program and navigate through with the WiiMote

  20. WiiProgram – Testing: • 3 JUnit Test Classes (1 for each background class), 30 tests total • Boundary testing on limits of the programs • Experimental User Interaction

  21. Resources – Budget:

  22. Resources – Time:

  23. What We Learned: • About piezo-electricity • About how WiiMotes work • Importance of constant and effective communication • Engineering Design Process

  24. Future Work: • There is a 4th phase to this project that is working to add more modules and finish up the room. • WiiProgram could use a few more xml sample programs written. • Expanding Piezo-electricity Floor for more modules
