156B Week 2

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

• • Decided on the adapter to place in home cage 

  • Will use jigsaw to cut into the home cage 

  • The CAD design is completed except for the water delivery system

    • Small modifications will need to be made (making the bride wider and lower on the cage)

Accomplishments from Previous Week

• • Finalized adapter design

  • Finished the CAD for the connection between the two chambers 

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

• • Decide on a water delivery system

  • Develop the CAD for the system 

  • Obtain parts and material to begin prototyping

    • Begin prototyping if sponsors get back to us quickly with parts

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

• • Perhaps the size of the PVC pipe should be 4 inches in diameter vs 3 inches (4/8 in person)

    • looking into bigger diameter size for the PVC pipe (4/8)

  • The water delivery system does not have to be powered by the raspberry pi (4/8 in person)

    • looking into using an Arduino to power the motor vs the raspberry pi (4/8)

  • The current water bottle is the main source of error because some water gets stuck in the cap (4/8 in person)

    • Looking into different designs for water bottle or a different motor/tubing to deliver water to prevent this (4/8)

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

• • Clarify with sponsor that we are building a low cost training center (4/5 by email)

    • clarified with sponsor that our project is parallel with the proto lab's (4/8 in meeting)

  • Take the pumps from the proto lab and build a water delivery system (4/5 by email)

    • Looking into implementing an arduino with the motors that are already being used (4/8)

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