Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Order forms have been sent to JV on 4/20/15
Prototyping Materials should be arriving this week
Tested load sensor provided by Steve -- responds linearly to changes in weight
Accomplishments from Previous Week
Finalized design of prototype after consulting with Tom
Found load sensor that may work with our parameters
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Begin fabricating the prototype (all)
To build the double-bar grating to test immediately (Jeremy)
Update new design with slider hanging from top on Solidworks (Ben & Aaron)
Update Website (Cheuk)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Approved by sponsor to purchase $160 load sensor to test (in person on 4/20)
We will purchase it for testing
Test grating to ensure mice can eat through the double-bar grating (in person on 4/20)
We will test this right after we build the double-bar grating -- we will take it to the mice labs to test.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Look into proximity sensor & spring combo for alternative sensor system (in person on 4/15)
Slider goes on top and mechanism hangs from it to reduce food particles jamming the slider (in person on 4/15)
Look into different scales for measuring weight (in person on 4/15)
Fish Scale
Cheap $10 digital scale
Much amplification and filtration needed for signals in current design (in person on 4/15)
Possible Lever Option (in person on 4/15)
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
