I wanted to build a wireless sign that could be portable, and setup anywhere using any mobile device. Possible uses are for store promotions, yard/flea market sales, tailgating, parties, office use, and public events.
The design is based on an ESP8266 MCU which drives a 8x64 matrix display (basically two 8x32's daisy chained) and scrolls a message that is entered via web browser. To enter the message, you simply browse for the sign's wireless network AP, open a browser to 10.10.10.1 and then type your message into the web form, hit SUBMIT and your message scrolls. The Marquee runs on 5 volts DC @ approx. 2 amps.
The code is done so that the last entered message will be persistent across reboots/powercycles. Your last entered message will continue scrolling until changed.
For the ESP8266, I used the Wemos D1 Mini, but any 8266 chip should work. Comments are in the sourcecode on how to wire the display.
