DIY PTP Grandmaster Clock with a Raspberry Pi

tl;dr: I set up an open source Time Pi project to build a stratum 1 PTP and NTP timeserver using a Raspberry Pi. Time is important to modern society, and most of us have a clock on our wrist that's more accurate than at any time in human history. But highly precise time is important in many industries, especially robotics, finance, and media production. And with tech like VR working its way into homes, precise time may become more important there, too. The timing industry has many solutions for 'grandmaster' clocks, which take in highly accurate time from GPS, GNSS, or other atomic-clock-backed time sources, and distribute it to local networks with extreme precision—down to the nanosecond range—using PTP. Historically, setting up a DIY PTP grandmaster clock server was a painful and expensive endeavor, pricing out most hobbyists. So I'm introducing a project that's been in the works for some time: Time Pi, a stratum 1 PTP and NTP timeserver based on a Raspberry Pi 5. In the picture ... Read full article.
