11000 Soldering kit: DCF radio-controlled clock

This radio-controlled clock sets itself independently thanks to the integrated DCF module and shows the current time using four large seven-segment displays. The clock housing is made from blue acrylic. Any USB-A mobile phone power bank can be used as a power supply, and the board has a backup battery holder for CR2023 batteries to interim buffering of the time. If the clock is unable to pick up the required radio signal, if the signal is too weak for instance, the clock can be set manually at any time. The soldering kit comes with detailed assembly instructions. The assembly instructions are also available as a video.
