Dragonfruit Next Steps for Spring 2017
Current Status
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
Problems
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
Next Steps
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
