Attended: Mengyuan, Creighton, Scott

• Compared the fourier transform of the microphone readings at different fan settings
  • Filtered out the DC component
  • Determined that there isn't any useful information from just the fourier transform
  • There's been some difficulty with implementing different Fourier analysis techniques, so this analysis will be put on hold.
• Found a hardware implementation for an interrupt which led to consistent measurements for counting clock cycles.

• To Do:
  • Replicate Andy's test and results with four microphones and in different environments by the end of this week
  • Design a PCB by the end of this week
  • Etch/mill PCB by the first week of November
  • Test hardware interrupt implementation.
