Dragonfruit Team Meeting - October 16th, 2017
Attended: Kevin, Kyaw, Tyler
Updates 10/16
Started soldering circuit
Updates 10/19
Continued soldering
Found 0 ohm resistor (pkg 0805)
Tested using heat lamp
Voltage across VCC on the charging ckt (on board) spiked whenever we turned on the heat lamp to simulate the sun
Spiked to ~6.4V and suddenly dropped back down to ~4 V
This could be one of the problems why the board keeps dying
Potential solutions:
Capacitor (choose a right value?)
If the voltage spike is due to current, we could use an Inductor
Tasks
Review csv file for Weatherbox deployment analysis
Code an arduino to monitor current drawn by charging chip
Start soldering next week (Tyler)
Start with charging chip
Investigate short circuit current of solar panel (Kyaw)
