๐Ÿ“…Timetable

  • 10:00 Morning Brief
  • 10:30 Team work with External Mentors
  • 13:00 Lunch
  • 14:00 Team work with External Mentors
  • 17:00 Github Updation

๐ŸŽฏ Objective

  1. Improving sound quality of prototype
  2. Adding another microphone for a stereo setup
  3. testing prototype with different audio samples
  4. Gaining feedback from mentors
  5. Make a circuit diagram on Sirkit Designer IDE
  6. Remove problem of Bone conducting transducers overheating quickly

๐Ÿงช What We Did

  1. Removed background noise and static from microphone by implementing capacitors and resistors between the the two modules
  2. Added a second MAX9814 module to provide stereo sound
  3. Made a circuit diagram on Sirkit Designer IDE
  4. Fixed promblem of Bone conducting trancducers overheating quickly using ressistors to decrease the current given to the transducers

๐Ÿ“ Notes/Observations

  1. Resistors and Capacitors improve sound quality
  2. Heating problem can be fixed by ressistors
  3. Messy wiring causes static and muffuled audio

๐Ÿ›  Next Steps

  1. Adding all components to a PCB
  2. Fitting components in a 3D printed case
  3. Add a switch to turn glasses on and of
