Week 10

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

• • Analysis/Tests:

    • Calibrated Potentiometers using Multimeter and Recording Data at Various Angles of Rotation

      • Results = Linear

    • Tested and Calibrated Hardware in the Wind Tunnel and using O-Scope

      • Results = Performed very well: Clean Signal, Linear Relationship of Voltage to Wind Speed, and similar if not better results than anemometer provided by Hunter (tested earlier in quarter)

    • Preliminary Tests of Entire Device were Completed

      • Results = After debugging the program, an Effective and Successful Program/Device was Accomplished (First Video under "Multimedia" link on webpage)

  • Design:

    • Refined and Updated CAD, and 3D Printed New Components for an Optimized Device

  • Fabrication:

    • Spent much time Refining the Assembly to Create a Better Rotating Anemometer

Accomplishments from Previous Week

• • Refined CAD and 3D Printed New Components

  • Refined Assembly

  • Edited Report

  • Completed Draft Poster

  • Calibrated Potentiometers

  • Calibrated/Tested Hardware and Signal with O-Scope and Wind Tunnel

  • Ran Preliminary Tests on Entire Device using DC Motor and Household Fan

  • Reserved Parking for Sponsor for Poster Presentations

  • Contacted Isaiah about Space Needs for Poster Presentations

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

• • Complete a Final Testing of the Entire Device's Performance in the Wind Tunnel (3/13) - All 

  • Complete a Final Presentation of the Project and Hardware Demonstratation at Hunter -All

  • Complete Final Drafts of Poster, Report, and Webpage - All

  • Optimize Hardware and Prepare for Poster Presentation - All

Sponsor Comments from Last Meeting (3/6) and Actions Taken to Address these Comments

• • Call Mark Shearin (Hunter Industries Electrical Engineer) for help with Microcontroller

  • Action = Was Contacted, but debugging was already Completed

• Find out about Wind Tunnel Testing

  • Action = Wind Tunnel Testing was set up with Isaiah Freerksen for Friday (3/9) and Tuesday (3/13)

  • Find out about Parking for Poster Presentations

  • J.V. Agnew was Contacted for a Reservation

Instructor Comments from Last Meeting (3/6) and Actions Taken to Address these Comments

• • Possibly use Fan/Oscilloscope for Demonstration during Poster Presentations

    • Action = We have a Fan, and its Speeds have been Measured to Test Accuracy of Device with a Hot-Wire Anemometer

    • Action = Isaiah Freerksen was also contacted for Space Needs

  • Possibly use Decals for Wind Speed Dials

  • Action = Decal Paper was Procured

Risks and Areas of Concern

• • Microcontroller/Software Issues were Resolved (3/12) with a Bread Board

    • The Proto (Soldered) Board to be Tested Again (First Testing, 3/11 wasn't as successful as with Bread Board on 3/12)

      • Check Relay and if it's Functioning Correctly

Resources or Information Required but not Available

• • N/A

Schedule

• • Complete Final Wind Tunnel Testing on Tuesday (3/13)

  • Finish Final Reports (3/16)

Budget (list amount spent and amount remaining)

• • Amount Spent = $430.20 (Estimated $300 to be Spent on Hardware and Microcontroller Accessories to Build 4 Prototypes, and Allow for Program Optimization)

  • Amount Remaining = $2069.80

Progress on Report and Webpage

• • Made Edits to Report based on Peer Comments; Final Draft Being Worked on

  • Final Webpage is Being Updated and Worked on as well
