Week 9

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

• • Analysis/Testing:

    • Copper Coils and Connections have Been Optimized and Tested and are Ready for Integration with the Electronics

  • Fabrication:

    • Fabrication has Begun

    • The Preliminary Design has Been Completed and is Ready for Electronics Integration

    • The Board Layout is Complete, and the Program is Being Written for the new PIC Microcontroller

  • Design:

    • After Preliminary Fabrication, Updates in the CAD have been Made in order to 3D Print a More Updated Final Design for Optimization

Accomplishments from Previous Week

• • Completed Class Assignments: Final Design Review Presentation, Second Draft of Report/Webpage

  • 3D Printed Parts and Began Fabrication

  • Optimized Copper Coils were Made

  • Microcontroller Program on new PIC Microcontroller has begun and is being worked out

  • Schedule, Bill of Materials, and Budget were Updated

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

• • Complete Draft Poster (Eric A. - Lead, All will Contribute)

  • Complete Microcontroller Program (Isaac K., All must Aid)

  • Complete Fabrication/Assembly (Anthony C. - Lead, All will Contribute)

  • Preliminary Tests on the Device (Eric K. - Lead, All will Contribute)

  • Optimize (All)

Sponsor Comments from Last Meeting (2/28) and Actions Taken to Address these Comments

• • Leave a .076-.127mm (.003-.005") Gap Between Parts to Be 3D Printed, which are Modeled to Fit Concentrically

    • Action = This Adjustment was Made in the Updated CAD for the Next 3D Print

  • Use of Gasket During Fabrication

    • Action = A Sealant will be used where Necessary when Fastening the Plastic Parts Together

  • Dials for Potentiometers

    • Action = Space was Added Between the Potentiometer Knobs to Allow for Wind Speed Dials to Be Placed (Information on Making Sticker Speed Dials will be Needed)

Instructor Comments from Final Design Review (2/28) and Actions Taken to Address these Comments

• • Press Fitting the Bearing in the Plastic may be Risky

    • Action = Team is Fabricating and Experimenting with Press Fits in the Plastic - No issue yet, but for Long Term Reliability, Alternative Fitting may be Necessary

  • Magnet Should Not Affect the Electronics

    • No Action Required for Current Design

  • Consider Injection Molding in Design - Use of Fillets/Uniform Thickness

    • Action = The CAD has been Updated after the First 3D Printing and these Comments have been Addressed

Peer Comments from Final Design Review (2/28)

• • Consider Injection Molding in Design

  • Try to Make Relay Easily accessible in Case of Malfunction

  • Move Less when Switching Speakers during Presentation

  • Possibility of 3D Printing Undersize Hole and Machining Proper Size for a Press Fit

  • Will Birds be an Issue?

Risks and Areas of Concern

• • Working Out the Micrcontroller Program with the New Microcontroller

Resources or Information Required but not Available

• • N/A

Schedule

• • Create a Working Prototype this Week, Test, and Optimize

  • Finish Draft Poster

Budget (list amount spent and amount remaining)

• • Amount Spent = $430.20

  • Amount Remaining = $2069.80

Progress on Report and Webpage

• • Report - Second Draft Completed - Will Review as a Team to Address Necessary Edits before Beginning Final Draft

  • Webpage - Second Draft Completed - Continuously Used and Managed
