In terms of bringing new life to older hardware and devices, the Raspberry Pi is a great opportunity to restore function with modernized features. Today we’re sharing an amazing Pico Atomic Clock idea that does the exact way to do what. The project was developed through VEEB Projects; the project restores the functionality of a railway station clock by using the Raspberry Pi Pico, which can verify the time is correct using a radio.
VEEB Projects is not a stranger to Pi projects. This Swiss-based developer frequently offers micro-electronics projects. One of the latest examples is that of the Heating-O-Matic. Another Pico-powered project is designed to automate heat control with a temperature sensor and relay. In the video demonstration, the team used the set-up to cook two hamburgers.
As per VEEB Projects, the idea of this project was not just to restore the clock to a functioning condition but also to ensure that it didn’t require an internet connection to function. This resulted in developing a radio-based system that checks the time with the DCF77 signal that has been a European broadcast in operation since 1973. Then, it transmits the current time, as calculated by atomic clocks.
Its Raspberry Pi Pico is connected to a ferrite receiver used to receive radio signals, like the DCF77 signal used for this experiment. An RTC (Real Time Clock) module is used to ensure that the clock’s time is maintained between the signal tests. To regulate the mechanism that controls the clock’s arm, the team has added an H-Bridge motor controller L298 to the mix.
The DCF77 signal transmits time by sending a stream of information that the Pico can interpret. After the Pico has processed the movement, it utilizes the data to determine the clock’s time, using the L298 H-bridge to shift its arms.
If you’re interested in reviving this build, then you’re in the right place. VEEB Projects has made available everything you’ll need to start with a build tutorial demonstration video, as well as the complete source code. Then, visit the official page on GitHub.
