 8x8 RGB DOT MATRIX DISPLAY as CLOCK, EMOTICON DISPLAY, NEWS FEED DEVICE Would be interesting to build a multi-function RGB color display device.  Good to have  display of time, images and any other chamak (custom messages, RSS Feeds,etc) ESP has good support for RGB Led via the Fastled library.  Bought and interfaced an 8x8 RGB from an online store with an esp8266 Fabricated a casing with the face and the box from a local vendor The FASTLED  capabilites/effects are as below. FASTLED is available here

Added advantage would be to have it connected on the internet and splashes messages to it. A WIFI based solution would be much better for easy access to the home/network ecosystem Using an accurate RTC like DS3231 and Wifi chip ESP8266, a PCB was fabricated. Also there was a need to make a good case to host the electronics. Acrylic case making is cheaper as compared to 3d printing. Found an enterprising acrylic fabricator who made an amazing case.  The power supply was embedded in the back of the case so it could be directly plugged into the wall socket or the ESP8266's USB power connector provided for at the side of the casing. Uses the MajicDesigns MD_MAX72XX library from here  MajicDesigns MAX72XX library The fabricated DMC looks as follows: Mains Enabled Clock The DMC can be run off either AC mains or an extern...
