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

• • Reviving the previous design

  • try our best to get the prototype done by the end of this week. 

Accomplishments from Previous Week

• • Photointerruptor prototype 

  • Calibrating/testing system. Communication of the system.

    • How the previous system works with the ComPort. 

  • Time with Steve Roberts about the RaspberryPi. No not going to invest time in this, and focus more on mechanical part.

  • Consisting on using the PCB board from last year.

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

• • Photointerruptor housing finalized

    • Test with mouse (confirm with sponsor meeting)

  • Look into clean/flushing the system, valve connector

    • Talking to Ian about that

  • Diagnose pressure sensor and recalibration

  • Determine wired or wireless (ask sponsor on Thursday meeting 1/23/20)

  • Sara and benson sync stuff

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

• • Maybe need hard plastic for the photo interrupter housing 

  • glue and need more support of the interrupter housing (better to not using glue) OR maybe we can have a clipping system that can have one part from outside and one part inside 

  • select the solution on the GUI, and save the data in to CSV file with a input file name (auto dates, input mouse ID and etc)

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