Notes for Fiona

• Below is all of the progress so far, with CAD files located in the Electronics Fixtures>Wind Vane folder
• The first step is to look over this information, make sure you understand the requirements and the current design
• Finalizing the design:
  • We should already have all the materials we need, including the bearing and magnetic encoder
  • The center of mass of the vane needs to be over the center of rotation (you can do this calculation in Solidworks, look up how to do it, you may need to set materials for parts with accurate densities). We probably need a way to adjust the weight in front, likely by adding a bolt and putting washers on it
  • Minimizing necessary bolts/nuts, maybe try and use some heated inserts in the 3D prints?
  • 3D printing / assembling components, soldering pins on magnetic encoder and testing functionality with encoder and magnet
  • Making sure that the current bolt pattern on the bottom can integrate with the counter balance mounting system

Design Requirements

• Wind angle measurement precision of <1 degree
• Responds quickly to changes in wind direction
• Versatile bolt pattern for mounting to wingsail counterbalance
• Provides exit points for sensor wires

Constraints

• As lightweight as possible
• Preferably built with parts we already have
• Must work with AS5600 magnetic sensor chip

Sensor Requirements

• Diametric magnet is 3mm diameter 1mm thickness
• Magnet must be 1-3mm above the exact center of the chip for optimal operation
• Note: David Sellers also designed a mount for the same sensor and you can likely use some of his CAD models, which are in the OneDrive folder
