The SNTP synchronised clock (ssc) is an ESP8266 based time of day clock with an LED display..

Design criteria The design criteria are:

  • small, portable, powered from a 5V USB power supply;
  • synchronised to a SNPT (simple network time protocol) server;
  • flexibility for a range of displays (74HC595 static, TM1637, HT16K33);
  • configurable time zone offset and daylight saving offset;
  • configurable from a web page;
  • switchable HH:MM and MM:SS display formats; and
  • switchable daylight saving mode.
  • The concept is that it is synchronised to net time, and the only adjustment needed through the year is to flick the daylight saving mode.
