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

Attended: Alex(s), Kayla, Becky

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
