Work in progress. Not yet ready. Do not produce PCB according to this project! This will not work.
This is a KiCad project for building a clock using these two VFD displays:
-
Radio controlled clock
-
Clock face time display
-
Additional 8x text display, allowing to show
- Date
- Temperature
-
5 buttons
-
5V operation
-
The VFDs are driven by 2 PT6315
-
The clock is controlled by an Atmega328P
-
Time signal will be received from DCF-77 by the Pollin DCF-1 receiver
-
There is a USB-to-serial port using CH340G
- For an Arduino-like programming interface
- For optional control of the clock via PC
-
Battery backed clock
-
FRAM for saving settings
