Word clock is unique digital clock that used shine word to show the time. the project is built based on PIC 16F877 and uses mains to ensure that it stays accurate. To build this project, you need to make custom PCB and make word pattern that tell the clock as etched areas. The clock use 5mm Blue LED to shines the word.
“I made the stencil using another fiberglass PCB. Just etch the board using the same method you used for the controller and display PCB, and lacquer it to protect the front of the display,” said Doug Jackson, the project designer.
