Last crawled date: 4 years, 11 months ago

Assembly of a small 77.5 KHz transmitter, to be able to set the DCF77 clocks that do not correctly receive the signal from the transmitter in Germany. This transmitter is portable, works with a 3.7V battery and is very accurate, since it takes the date and time information by previously synchronizing its clock through an NTP server. This transmitter is built from the ESP32 module, coupling a small 64x48 pixel 0.66-inch OLED display.
