156B Week 10

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

• • Finished main fabrication of sampler (besides mesh bags)

  • Currently finishing up fabrication of dispenser - tubing has a lot of friction with the wire so it is hard to pull it through, so we are getting new tubing that will work better

Accomplishments from Previous Week

• • Got parts for sampler (brass mesh, brass screws, etc.)

  • Fabricated sampler

  • Cut tubing used for dispenser

  • Bought hose clamps to attach tubing to sampling

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

• • Cut mesh bags to correct size (Tanima)

  • Swage wires to be used with tubing (David)

  • Buy new tubing with less friction (Joseph)

  • Buy more fishing line and mesh bags (Bridget)

  • Edit Report with peer review comments (David)

  • Finalize poster, report, and website (All)

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

• • Need to buy Go Pro Housing

    • We have bought and received the standard go pro housing

  • Can't make presentation on Thursday or Friday

    • We will schedule one over the weekend or early next week

  • They want a parking space for the poster presentation

    • We will request a parking space soon

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

• • Meeting on 5/23:

    • Recommended testing at UCSD CanyonView Pool instead of at the Del Mar Lagoon and we will likely test there

    • Miscommunication about number of wires to be used. Dr.T and Pedro though 4, but we clarified that it was only 2

    • Set-up sponsor presentation during week 10 & go there to present to them

      • Tried to set up a meeting for this week: not many times where all of us are free, will most likely present on the weekend or early next week if needed

    • Website and report can be slightly altered up until the poster session (week 11), but 99% should be completed one week prior

  • Dr. T. and Pedro wanted updates on our project throughout this week

    • Have emailed them a few times to update them on progress

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

• • N/A

Risks and Areas of Concern

• • Amount of friction between pulling cord and PVC tubing is too high - cannot pull wires through tubing easily

    • Cord length: 25', Tubing length: 20'

  • Likely will not get to mount camera before the end of the quarter - Chuck and Kara have not been responding for a time to get the camera from them

  • Possibility that we need to use weights; will likely mount them to the sampler mesh wire

Resources or Information Required but not Available

• • N/A

Schedule

• • 5/31: Finishing dispenser fabrication

  • 6/1: Pool test and demo with Dr. T

  • 6/2: Finishing touches on product

  • 6/3: Finish Presentation, Report and Website

Budget (list amount spent and amount remaining)

• • Spent: $585.64

  • Remaining: $2114.36

Progress on Report and Webpage
