A popular project among microcontroller aficionados is to build a radio-controlled clock. Tiny receiver boards are available, with a pre-adjusted ferrite antenna, that receive and demodulate the DCF77 ...
Required components The first things you will need is DCF77 module and a crystal based Arduino. Attention: the Arduino Uno is NOT crystal based. Although there is a crystal on the board this crystal ...
Linux-Fan, Ma_Sys.ma (Ma_Sys.ma@web.de) Die Ma_Sys.ma DCF77 VFD Raspi Clock ist eine selbst gebaute Digitalfunkuhr auf Basis eines Vakuum-Floureszenzdisplays, welche durch einen Raspberry Pi Pico ...
Based on an Atmel AVR microcontroller with 8kB flash, the LED clock uses a German time signal in the form of DCF77 Receiver as it was connected to an Ethernet network to serve as a NTP server while ...
Needing to drive two devices with a DCF 77 signal, I made an NTP client time server with two output channels. Elektor published in its March-April 2018 issue an excellent article describing a module ...
[Brett] just completed his DCF77 Master Bracket Clock, intended to be a backup to an old logic controlled clock he made. For our readers that don’t know, DCF77 is a German longwave time signal whose ...
Synchronized by a DCF77 module and backed up by a DS2331 RTC, this time server provides a TTL time signal via an optocoupler and distributes this signal via a 433 MHz transmitter to synchronize alarm ...
