• Deployed at Andrew's house
  • Boards worked well inside, but Bumblebee failed outside
    • Box started to whine and stopped transmitting when solar panel created a spike in voltage
    • Possible cause: single voltage regulator on PCB is not enough to handle power provided by the panel

• Figure out why the board doesn't respond well to power from the solar panel
  • Measure current/voltages to and from the panel with the battery and simulated sunlight
• Possibly deploy second board

• Tested previously deployed Bumblebee with solar light in the lab
• Removed voltage regulator on board to see if the problem was a current draw problem
• Attempted to use a through hole voltage regulator with a higher current output
• Tested other board with solar light to see if that board also had a problem
• Noticed that second board's voltage from the solar charging chip would fluctuate when the board or panel would be moved
• Noticed the male barrel jack on the solar panel that was deployed was broken
• Tested board with new panel and there was no buzzing like there was on the deployed board
• Voltages on board with new panel stayed constant

• Test new board with new panel to see if it can send packets
• Replaced voltage regulator on first board
• Create a new housing for second board
• Deploy!
