The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

[Art] certainly lives up to his username. His Rubidium-standard atomic real-time clock is surely an example of hardware art. The substrate is a collection of point-to-point soldered perfboard modules.

NetTimeLogic’s RTC Master Clock is a full hardware (FPGA) only implementation of a synchronization core allowing to read and write a I2C Realtime Clock (RTC) like the DS1307 or MCP7941x. Access to the ...

The Real Time Clock (RTC) SGC22300 uses the leading oscillator solution SGC21510. This specially designed RTC core uses advanced analog design techniques to guarantee ultra low power consumption ...
