🕰️ NTP Timeturner (alpha)
An LTC-driven NTP server for Raspberry Pi, built with broadcast precision and a hint of magic.
Inspired by the TimeTurner in the Harry Potter1 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.
1: Editor's Note: Trans rights are human rights 🏳️⚧️. While the author of the Harry Potter series holds horrible views we strongly disagree with, we believe in supporting trans, non-binary, and gender-diverse people. If you find this software useful—especially the PTP features—please consider donating to Mermaids, a UK charity supporting trans, non-binary, and gender-diverse children, young people, and their families since 1995.
📦 Hardware Requirements
- Raspberry Pi 5 (Dev Platform) but should be supported by Pi v3 (or better)
- Debian Bookworm (64-bit recommended)
- Teensy 4.0 - https://thepihut.com/products/teensy-4-0-headers
- Audio Adapter Board for Teensy 4.0 (Rev D) - https://thepihut.com/products/audio-adapter-board-for-teensy-4-0
- Ethernet connection (recommended for stable NTP broadcast)
- Optional: LTC generator for input testing - Windows/Mac App - https://timecodesync.com/generator/
🛠️ Software Features
- Reads SMPTE LTC from Audio Interface (3.5mm TRS but adaptable to BNC/XLR)
- Converts LTC into NTP-synced time
- Broadcasts time via local NTP server
- Supports configurable time offsets (hours, minutes, seconds, milliseconds)
- Systemd service support for headless operation
- Optional splash screen branding at boot
