Happy Bubbles NFC / RFID device

Hi guys,

I created a little device I've wanted for a while that uses the ESP8266 to read NFC/RFID tags and when it gets one, sends it to an HTTP URL. Using this, I can do all sorts of cool home automation stuff like play a music album or youtube video that I can associate with an NFC tag.

The whole thing is open source and open hardware and you can check it out here: https://github.com/happy-bubbles/nfc
Right now it's simple enough to just wire together with a NodeMCU board and an RC522 cheapo RFID module, but if people like this I could design a PCB to make it look nicer.

Anyway, maybe this is useful to someone else too.

I've updated the project with an Eagle PCB.

Cut the path between the pin 3-32, chip rc522, change the type of interface with SPI to RS232, will be easier to communicate with ESP8266, a smaller program, fewer problems.

Well I'm not using a raw MFRC522 chip, more like the cheap modules like these: http://www.amazon.com/gp/product/B00VFE2DO6
On them, there's not really a way to change from SPI to UART. So that's why I chose SPI, the availability and price of the modules was important to me to choose to support them.
