Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Nearing a Final Design, and will conduct a design review with sponsors this week
Will develop a new solid one piece anemometer design (3 cups all connected for one solid mold)
Will develop a housing design using two bearings on the shaft
Will use a magnet coupled to the anemometer shaft to generate a signal as it spins near a coil of copper wire
In the process of testing optimal magnets for generating a signal once magnets from purchase order are procured
Optimal magnet will determine size of shaft of anemometer for final design
Accomplishments from Previous Week
Met to discuss/develop a final design consideration
Along with the assistance of Tom Chalfant and Isaiah Freerksen, developed a way to test optimal magnets and save money, material, and time.
They also had some tips in creating a more solid final design as far as fitting the bearings into the housing
Worked on electrical layout/programming of microcontroller; however, ran into a problem with the signal and working to resolve
Began first draft of report and proof of concept presentation slides
Researched bearings, magnets, and weather proof sealing items for final design
Began designing 3D model of final design
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Design Anemometer and manage design/fabrication of hardware - Anthony Chong
Design Housing and manage team liaison duties- Eric Abraham
Model Electrical Components and manage purchases- Eric Kenyon
Develop Working Electrical Layout and Program for Microcontroller - Isaac Kim
Complete Proof of Concept Presentation to Class - All
Complete First Draft of Report - All
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments
Use 2 bearings to stabilize the shaft of the anemometer
Action = Developed a final design consideration using two bearings
Check Heyco for rubber sealers and K&J Magnets for possible magnets
Action = Researched these two manufacturers and are in the process of procuring useful products from them
Instructor Comments from Last Meeting and Actions Taken to Address these Comments
Use 2 bearings on anemometer shaft to reduce torque/wobble on shaft
Action = Developed a final design consideration using two bearings
Can use aluminum shaft for anemometer because it will not affect the magnetism
Action = Considering aluminum shaft for anemometer (depends on ability to machine a very small shaft - discussed with Tom Chalfant)
Can possibly avoid press fitting anemometer shaft into bearing to allow for easier adjustments
Action = Developed a better way to test/optimize the Wind-Clik, so that the final fabrication will allow for the shaft to be press fit for weather proofing
Risks and Areas of Concern
Electrical signal from the spinning anemometer has some noise when all the electronics are connected
Resources or Information Required but not Available
N/A
Schedule
Finish Proof of Concept Presentation for Class on 2/7
Complete First Draft of Report (2/10)
Have electronics working, and design established by the end of the week
Budget (list amount spent and amount remaining)
None spent this week; however, we have submitted purchase orders for some electronics and magnets, and we are waiting for the orders to go through.
AC motor bought earlier in the quarter ended up not being used, so it will be returned with a small fee (about $6)
Therefore, currently $2500 remains in the budget and the return fee will be implemented when the transaction has taken place.
Progress on Report and Webpage
Report has been started and sections have been assigned to particular members.
Webpage is continually updated and refined.
