WWVB signal decoding using audio card

Synchronize most radio-controlled ("atomic") clocks and watches using almost any phone or tablet

Arduino based clock that syncronizes to NIST's atomic time signal WWVB. Uses ES100-mod to recieve and decode the time broadcast.

WWVB emulator using an ESP32

Clock receiver for project RFID-MS, project MOMO and project TAMDL (Animal Mainboards). Is automatically synchronized to a time code transmitted by a radio transmitter connected to a time standard such as an atomic clock.

mikrobus WWVB Time Signal Receiver Module using ES100-MOD

A simple modification to an atomic clock provides a visual indication when the WWVB signal is being received

JJY (WWVB) standard radio wave signal receiver library for Arduino.　Arduinoの日本標準時受信モジュール用ライブラリ

Arduino library to transmit WWVB and JJY with a 40kHz or 60kHz carrier

A wspr transmitter/receiver using the QRP Labs arduino shield

Generate WWVB timecodes for any desired time

Alarmclock based upon a Arduino Uno with an 3.5 inch (320x480) TFT shield.

WWVB 60Khz Full functionality receiver/parser for i2c bus based ES100-MOD

A multiband time signal radio transmitter for Raspberry Pi

Running a vintage secondary clock, using DCF77 or WWVB and Raspberry Pi Pico. Also a version that does not use Radio and uses a Pico W.
