*156B Week 6

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• • Microphone tested to see if USV's could be picked up

  • In process of completing testing of microphone (position, sensitivity, etc)

  • In-process of completing finalized Y-maze design and testing for rigidity

Accomplishments from Previous Week

• • Test sensitivity of microphone (Phong, Caren, Sonya)

  • Finalize LabView programming (Sam, Sonya, Phong)

  • Finalize plan with sponsors (all members)

  • Install LabView on laptop used for performing experiments (Sonya)

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• • Incorporate sensors into LabView (Sam and Phong)

  • Test microphone for appropriate distance away from testing site (Sonya)

  • Complete Y-mazes(4) with improved design (Caren, Phong, Sonya)

  • Find/Fabricate microphone stand (Sonya)

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

• • Incorporate handle and base plate into Y-maze design- 5/3 (meeting): Completed

  • Include sensors into Y-maze design: 2 on each length of the Y-maze- 5/3 (meeting): In Progress

  • Try to run both Viewer (video) and LabView (audio) programs on the same computer- 5/3 (meeting): Completed

  • Adjust height of Y-maze- 5/3 (meeting): Completed

  • Complete audio testing with microphone- 5/3 (meeting) :Completed

  • Test distance of microphone- 5/7 (meeting): Scheduled

  • Install and execute LabView program separately from Viewer program on a designated laptop- 5/7 (meeting): Completed

  • Synchronization will be completed by simply starting both programs simultaneously- 5/7 (meeting): Addressed

Instructor Comments from Last Meeting and Actions Taken to Address these Comments  (indicate date of comments and if via email or in person)

• • Bring everything to meetings- 5/3 (meeting): Addressed

  • Use external triggers (ultrasonic transmitter) to test synchronization- 5/3 (meeting): Addressed and discussed with sponsors

  • Record a mouse- 5/3 (meeting): Completed

  • Save an avi file and play using LabView- 5/3 (meeting): Completed

  • Calculate bytes per second- 5/3 (meeting): Completed

  • Create comparison table- 5/3 (meeting): Completed

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• • None this week

Risks and Areas of Concern

• • Sensors: adding them to the system requires holes in the Y-mazes

  • Will sound proofing be required? (there are outside noises that could skew data)

  • Y-maze: 1) New size may be hard to cut in LaserCam 2) How long will the braces be?

Resources or Information Required but not Available

Schedule

• • Complete Y-Mazes: 3/18

  •  Incorporate sensors into system (physical and programming): 3/18

  • Complete Testing of Microphone: 3/11

  • Purchase more acrylic: 3/10

  • Purchase/Fabricate microphone stand: 3/18

Budget (list amount spent and amount remaining)

• • • ~300 Ultramic 250K

    • ~30 Sensors

    • ~100 Acrylic

    • Approximately 2000 remains

Progress on Report and Webpage

• • Continue updating both report and webpage as testing is finalized
