This is an old revision of the document!


Attended: Keane, Kevin, Tyler, Kaeo

  • Spoke with Garret on Skype about the board
    • Check the power supply with the ammeter to figure out the current input to the circuit
    • check voltage across the black capacitors in parallel without the solar panel
  • LED on sensor board for firmware to debug
  • Compare notes with cranberry on the sensor boards
  • ask kenny about using a wheatstone bridge to modify the battery and solar panel voltage instead of a voltage divider. for the ADC.
  • website looks at the battery voltage - ask kenny.
  • slower clock and take out the 5V boost converter (clock cannot run without 5V)
  • make sure the sensors can all handle 3.3V
  • make sure all the parts can run on 3.3V
  • N/A
  • Work towards implementing the board with a slower clock and no 5V voltage regulator
    • Slower processing speed
    • Less power consumption
    • Able to gather data at least
  • Look at data sheets to be sure parts can operate on a 8MHz clock and 3.3V
  • Look into how to remove the 5V regulator so that the board will still work
  • Code the currently working board with Firmware
    • currently planning to deploy the board that is already working, however this board will not last long without sun
    • come up with solutions to allow the speed without the power consumption

Reminders

  • Deployment early October (October 2nd), so try to make current board operational.
