Sat., June 11, 2022 – Marine GPS on a Pi

Dave will share his work in running Marine Navigation on a Pi including:

  • hardware requirements
  • how the zero could be used, but there are drawbacks
  • I was unable to get a pi 4
  • at George’s suggestion, I decided to go with the pi 400
  • hardware modifications to integrate the GPS unit within the pi 400 case
  • introduction to and a brief overview of the OpenCPN Chart Plotter Navigation software
  • some ideas I have to make a more “system-critical” GPS solution (will implement if I have time)

Sat. Feb. 26, 2022 Making a music player – bits of Python causing grief

I decided to build my own Raspberry Pi music player using Python, as the available players didn’t really do what I wanted. This is Python at the beginner level, and the saga of making the player. Mostly it is about the little things in Python that caused me to stumble for a while. The music player is functional, the interface isn’t elegant, and I learned a few things about Python programming. – Don
