Here are the different GPS Modules I’m playing with or plan to play with: Continue reading “Sunday Geek Project: The Contenders and Setup”
So today is the day after my youngest son’s high school graduation party. Needing a break, I decided to work on my project to compare different GPS modules’ time keeping ability. So I built three Network Time Protocol (NTP) servers using Raspberry Pi’s and different GPS modules:
As I move from the prototyping stage to the testing phase, I hope to document the process, equipment, and results here.
