156B Week 4

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

• • Completed Y-maze

  • Waiting for microphone in order to do testing and building mount.

  • Speak to Ingo Foldvari from National instruments about the issues related to using labview. 4/23

  • Need to speak to sponsors about using USB camera.

  • Plan on using vision modulus from labview to do recording/playback programming for video

Accomplishments from Previous Week

• • Completed Y-maze(Caren,Phong)

  • Progressed on video programming(Sonya)

  • Completed most of the programming for audio (Sam)

  • Ordered all parts(microphone, sensors) (Sonya)

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

• • Have all hardware(microphones) tested (everyone)

  • Start building bracket for microphone (Caren, Phong)

  • Modify the audio signal so humans' ears can hear mice call(Sam)

  • Try to complete Video programming (Sonya, Phong)

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

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

• • Would like to see more about the specific challenges such as sampling frequency- 4/19 (Presentation comments): Addressed in team meeting for next presentation

  • Look into using Fourier Analysis to recreate "lost" high frequency component- 4/19 (Presentation comments): Addressed in team meeting

  • Complete more numerical discussion of sample frequency in next presentation- 4/19 (Presentation comments): Addressed in team meeting

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

    (All Presentation Comments from 4/19)

• • Good presentation

  • Adjustable Y-maze and filtering the signal: Kevin Chau

  • Microphone position (does it have to be above the maze?): Thomas Tran

  • Noise is going to be an issue and what are the differences between the different devices: Luis

  • More pictures and cad models/Research bat detector to see if it can record data or simply detect ultrasonic noise: Emmanuel

  • Does anyone wanting to interact with the project have to have LabView: Marwan Azzam

  • Can insulation be incorporated into the design to reduce ambient noise?: Adrienne Apacible

  • List more about the new microphone and justifications to use it: Andy Chen

  • How is the resolution of the microphone?: Young Woo Seo

  • mp3 format is a compressed form so make sure you don't lose data and be aware of background noise: Janak Dadhaniya

  • Look into broadcasting technology for synchronization and firewire connection: Travis Weightman

Risks and Areas of Concern

• • Sound-proofing the y-maze

  • Don't have backup plan for microphone

Resources or Information Required but not Available

• • Information about the current camera that sponsor wanted us to use

Schedule

• • Complete video programming 4/4

  • Synchronize audio/video 4/11

  • Build bracket for microphone 4/4

Budget (list amount spent and amount remaining)

• • ~ 300 dollars for UltraMic 250k

  • ~ 30 dollars for PIR sensors

Progress on Report and Webpage

• • Divided the workload amount member
