Attended: Kevin, Gordon, Tyler

• Transmission Test 1
  • Board lasted for 17 hours
  • Battery voltage was last recorded as 3.7V therefore unsure why board stopped transmitting
    • could be due to Ghost voltage or marginal short
    • Could also be due to Gateway crashing
  • After power cycling board, the board powered on and started transmitting

• Transmission Test 2
  • Board lasted for 56.3 hours
  • Battery voltage was last recorded as 3.0V meaning the battery discharged before ending transmission
  • HOWEVER, once power cycled the board was able to send heartbeat packets

• Dylan helped create a code for Arduino that would help us monitor if our XBee experienced a ghost voltage
  • This code will record voltages and notify when a voltage is greater than 3.3V
  • Having a voltage greater than 3.3V means that something other than the Voltage regulator is powering the XBee
  • currently we have no way of writing this data to a file
• Contacted Tyrin about 3D printing the rest of housing
• Testing board again with all sensors attached, and screwed into the housing
• Kevin working on Gantt Chart
• Gordon bringing together all necessary parts to populate another board (getting familiar with all the parts of DragonFruit)

• There is currently a bizarre lack of problems

• Deploy board
• Program board 4 and 5
  • use these boards for testing
• Complete redesign of new board
  • no parallel voltage planes surrounding charging chip if possible
  • new GPS and RTC components
