The magic that is the ESP8266

The title is a lie. Actually, I'll want you to be all excited about the D1 Mini NodeMCU – an all in one Microcontroller Combo that sports the ESP8266-12F, 4MB of Flash and a Micro USB port for easy flashing and power supply. 

How it all started.

This is probably as non-technical as it gets, as I'll explain a little the story on how my journey actually started: I was fascinated by split-flap displays.
