Updates
- Cranberry didn't go up before spring break
- Still aiming for 5 boxes at the end of the semester
- Need everyone's help to reach this goal
Cranberry Updates
- Tested charging, programming, sensors, switches, UART, XBee, I2C
- UART works
- Switches work
- I2C slightly works
- width of trace may not be wide enough for current
- trace could also be too long
- currently using 10 kOhm but could change to 4.7 kOhm
- could have put capacitor on wrong
- 16 bit ADC works
- Solar sensor has problems
- Op amp inputs are reversed
- Jon can cut the trace and rewire
- Charging chip not working
- Chip could just be bad
- Board is receiving power but not charging
- Chip is overheating
- Could cause problems in the future
- Need to find a way to dissipate heat better
Conrad
- Continue testing boards
Jon
- Will be soldering more charging chip boards for testing
- Will cut trace for op amp and rewire board
- Should notify Jon of any changes made to the board
Alex
- Would like to send out PCB for tree monitor tomorrow
- need to ask Kenny for payments on PCB
