Dragonfruit Team Meeting - January 17th, 2017
Attended: Kevin, Gordon, Tyler
Updates
Strangely, board 3 from last year works and transmits perfectly fine
possibly b/c it has not been powered on in a while
This board was showing major transmission issues last year
==Try putting screws into through holes==
Dylan wrote an arduino code to measure XBee voltage (watch for ghost voltage)
Currently doing a life time test of board
will move on to doing life time tests while housed and with solar panel
Problems
The board works fine, and we didn't do anything
Goals
Test XBee transmission when in contact with metal and without
Reprint housing bottom and Solar Panel holders (put holes in the screw places)
Use diode to avoid power from XBee
Find an appropriate diode
Find out where MCU could be powering the XBee from
Program Dragonfruit board 5
Measure for shorts
Oscilloscope
Talk to Ohta about possible plane tunneling issues
Figure out if repeated use damages/degrades the performance of the board
Test board after replacing Charging Chip
Find surface mount charging chip part (redesign board to use this part, may solve shorting issues)
Finalize Eagle schematics of GPS and RTC
