German Word Clock
Thanks to Mike for sending in his German Word Clock. He has used some SPI controlled RGB lighting strips to make wiring and controlling the lights simpler. So that the letters look good he has built and installed an MDF baffle with 100 light holes in it. ”To control the clock, an ATmega8535 is used. This is a real-time clock (DS1307), a Bluetooth module and a Darlington array to control the 4 leds around the clock, each of which represents the minutes (Example: The Time Clock “It’s five after two” and two LEDs lights -> Thus, it is seven to two). - 40 × 40 cm, so that you can read the clock at a distance greater good - Mirrored glass front panel or Plexyglas - “Wooden Shield” of the light cone to prevent unwanted light from letters - To clean aluminum frame around edges have - RGB lighting - Brightness sensor - Control by smartphone” ...
