156B Week 7

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

Need mock up testing for lighting

    • Use current camera and cardboard mock up of the housing

    • Test in a dark room to simulate amount of light at depth

Need to test Camera with mounts.

    • We have access to a shaker table and will meet with Chris Cassidy for an overview.

Fabrication of the Housing

    • Cutting

    • Welding

    • Machining

Test of camera in housing by shoving into sand.

    • Need to test camera on a computer, ensure software will not be a problem

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

    • Try camera out on a computer, look at software equirements.

    • Use Polyeuethane mold to connect wetmate cable to Ethernet.

    • Figure out how lens limits the resolution

    • Phone calls to camera companies , ask about sacrifices to operating at a high frame rate.

    • Look at ambient light requirement of existing camera.

    • Concerns about the deviation of the housing based on the wedge angle.

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

Comments from weekly meeting on 5/4/15

    • Confirm with Tom if the spring steel should be machined or cut by waterjet in the upper campus.

    • Ensure that we specify the tolerance on all dimensions of the spring steel.

    • Check the usage of a different screw, #5 screws are not standard- look at #4 and #6 or metric

    • Review of first draft of the report

        • Lots of Formating issues- We have agreed on a standard for formatting and will convert the document accordingly

        • Captions, figure size, figure font, everything needs to be readable.

        • Fix up predictions use calculated vs measured style.

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

    • Tom C.(5/4/15, in person):

      • Recomended we weld into the side wall to better connect and seal the window
