   3 The following command will download a repository containing a python
   4 script that can pull pressure data from the BerryGPS-IMU v3.5's BMP388
   5 : git clone https://github.com/getelectronics/PIBits.git

   9 - I ordered another two Raspberry Pi Zero W's and another BerryIMU-GPS.

  11 - I think I found the problem with the pressure sensor. According to a
  12   2020-03-12 post by johnmark at
  13   https://ozzmaker.com/forums/topic/temp-barometer/ , the BerryIMU-GPS
  14   version 3.5 uses BMP388, not BMP280. johnmark posted a link to a
  15   python script that works for the BMP388 pressure sensor at:

  19 - I have downloaded this PIBits git repository to jalrasaroa-02 and am
  20   testing it now. It works.
  21
  22 - I am checking to see how I can automatically update the clock on
  23   jalrasaora-02 via a network time server. Reading instructions at
  24   https://www.garron.me/en/go2linux/how-to-set-date-and-time-linux.html
  25   .

  27 - I am installing the `ntp` package described here:

  30
  31     $ sudo apt-get update && sudo apt-get upgrade -y && sudo apt-get install ntp
  32
  33   - I confirmed that the ntp time synchronization service is running with:
  34
  35     sudo systemctl status ntp
  36
  37 - I am creating a git repository to store executables and setup
  38   instructions for Raspberry Pi Zero W's used for logging:
  39
  40   - Location (GPS WGS84)
  41   - Air pressure (Pa)
  42   - Temperature (°C)
  43   - Direction (magnetic north heading)
