Story

My dream was a world map as a picture, in which our favorite places are currently displayed with LEDs in yellow during the day and purple at night. The background is a cork plate on which a world map is printed in the format 60x40 cm.

Through this 3mm thin plate can easily be put light emitting diodes. For 16 cities 32 LEDs were installed and wired on the back.

The control with the Raspberry Pi computer is done via a buffer board with 4 SN74LS374 devices.

The Python program contains a year table, which holds the sunrise and sunset times for the 16 cities per week. The current date and time are retrieved from the internet via WLAN and used to control the 32 LEDs.
