PTP and PTM over USB
Time. Measure. Compare. Have fun.
What is a Time Stick? ▾
- A USB Ethernet adapter with a hardware clock you can reach from Mac, iPhone, and Android apps — no custom driver needed.
- Measurements from hardware timestamps
- Two USB personalities: NCM 1.1 for Ethernet forwarding and a USB-local bootstrap service; USB MIDI for timing commands, hardware observations, and signed firmware.
- Safe firmware updates: bounded loaders keep RAM experiments separate from permanent installs.
- Reliable servos: app-run servos commit state only after the clock adjustment is acknowledged.
- Host correlation: a PHC/USB-counter bracket on Mac; a four-timestamp messaging path on iPhone and Android.
- See, hear, and feel time: audio, vibration, and flashlight pulses mark each device second.
