We were invited today to give a  seminar on "How to get started with Embedded Systems" in a local Engineering college. With very little time on hand, wanted to quickly show the capabilities of ESP8266.  So I decided to make a temperature humidity logger. With [https://thingspeak.com/channels/53608/private_show Thingspeak.com], it was extremely easy to log data and even trigger tweets!
