As we might live apart with our closed friends due to some reality resons which could be studying aboard, business travel, so on. To compensate for the missed contact with a certain relationship, I created Light Messenger, an IoT kit for a couple of friends having bi-directional communication with different light colors. With this kit, you can 1) select light different colors by rotation; 2) send your current selected light color by a single-tap; 3) or review the light color(s) the other sends by a double-tap.

In some cases, you might want to erase all contents of ESP8266 (including Wi-Fi settings, Sketch). You can try using esptool.py with below command line:
List all connected serial devices
ls /dev/tty.wchusbserial*Print your nodemcu port-id
$/dev/tty.wchusbserial14540Execute esptool.py -p [device_id] erase_flash
esptool.py -p /dev/tty.wchusbserial14540 erase_flashIf you have only one serial device connected, you could
esptool.py -p /dev/tty.wchusbserial* erase_flash| Name | Version |

This is a give away for a resigned professor, Saskia Bakker from the TU Eindhoven. In this project, I redesigned completely the software layer, the physical form was heavily built upon Saskia's Ph.D. prototope, Fireflies. Thanks for that! Besides, you could find my Wizard of Oz for the initial demo on her Goodbye party; I would also like give @mobizt credit for developing the Firebase Realtime Database library for ESP8266 as well as his time in fixing bugs.
