I have a new tutorial coming out here: https://www.youtube.com/watch?v=y-P627KBLBw
Inastructions, wiring and code are in my ESP8266 github repo here: https://github.com/MKme/ESP8266
I struggled getting the SD adapter working with ESP8266 at first so this should hopefully help someone avoid that. Cheers!
