I made some new stuff on this project. Now it has a «working» pre-prototype that can do Wifi+RFID+WS2812 Led ring.

To test the ESP, the Arduino system is good enough. I’ll explain here the steps to install it.

How to connect the ESP8266 and how to communicate with the default non-free firmware to test the device.

I just received my ESP8266-12F from Electrodragon. I’m going to document the steps to use that thing on a GNU/Linux machine.
