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

+- I ordered another two Raspberry Pi Zero W's and another BerryIMU-GPS.
+
+- I think I found the problem with the pressure sensor. According to a
+  2020-03-12 post by johnmark at
+  https://ozzmaker.com/forums/topic/temp-barometer/ , the BerryIMU-GPS
+  version 3.5 uses BMP388, not BMP280. johnmark posted a link to a
+  python script that works for the BMP388 pressure sensor at:
+  
+    https://github.com/getelectronics/PIBits/blob/master/python/bmp388.py
+
+- I have downloaded this PIBits git repository to jalrasaroa-02 and am
+  testing it now. It works.
+
+- I am checking to see how I can automatically update the clock on
+  jalrasaora-02 via a network time server. Reading instructions at
+  https://www.garron.me/en/go2linux/how-to-set-date-and-time-linux.html
+  .
+
+- I am installing the `ntp` package described here:
+
+    https://www.digitalocean.com/community/tutorials/how-to-set-up-time-synchronization-on-debian-10
+
+    $ sudo apt-get update && sudo apt-get upgrade -y && sudo apt-get install ntp
+
+  - I confirmed that the ntp time synchronization service is running with:
+
+    sudo systemctl status ntp
+
+- I am creating a git repository to store executables and setup
+  instructions for Raspberry Pi Zero W's used for logging:
+
+  - Location (GPS WGS84)
+  - Air pressure (Pa)
+  - Temperature (°C)
+  - Direction (magnetic north heading)
