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
