• No boards deployed
  • Transmission issues
  • Irregular voltages
• Board 5 fully populated
  • not programmed yet
  • LED for solar panel lights up
• Housing
  • Reprinted main housing
  • Need to print solar panel holder along with cover components
• GPS drafted onto sensor board

• Board stops transmitting even while supplied with 3.1V
  • Sometimes because of movement
  • Sometimes when moved a lot, still transmits perfectly
  • Sometimes stops transmitting when some pins are touched, but not all the time
• Board definitely stops transmitting when power is shorted to ground even for a very short time
• Voltage inconsistencies throughout the board at random times
• Power budget
  • Estimate : 6 days
  • Actual : 2 days

• Draft new PCB with GPS
  • get rid of led debug lights on sensor board
• Better solder charging circuit and MCU
• Roof data power budget
  • Grab current data of all parts from MCU?
  • Current test of entire board (come up with the best way)
  • possible current sensor implementation for Solar Panel
• Voltage test (and transmission tests)
  • Voltages with and without XBee
  • Voltages responding to touch
• Check board extensively for on-board shorts
  • This may account for our transmission problems
