**An LTC-driven NTP server for Raspberry Pi, built with broadcast precision and a hint of magic.** **An LTC-driven NTP server for Raspberry Pi, built with broadcast precision and a hint of magic.**
Inspired by Hermione Granger’s TimeTurner, this project synchronises timecode-locked systems by decoding incoming LTC (Linear Time Code) and broadcasting it as NTP — with precision down to the millisecond. Inspired by the TimeTurner in the Harry Potter series, this project synchronises timecode-locked systems by decoding incoming LTC (Linear Time Code) and broadcasting it as NTP — with precision as Hermione would insist upon.
