sonoffSonoff from iTead.cc is a small box with an ESP8266, a transformer and a relay, 2 connectors for input and output AC, supports 110-220v AC and costs 5 USD on eBay! How to resist? Don't! Just buy it!
Usage? I use one of these puppies now to control my home file server: it's a Raspi 2 with an USB HDD connected. I use it once a month these days, it doesn't need to be always on (waste of energy and ageing of the Raspi & HDD). Now, my SonOFF controls them so I can turn on the pair, do what I need, watch that movie, and turn it off after. Big saving of energy ! (^_^)v
Points of interrestAn ESP8266 with transformer and realy for 5USD: do I need to say more??
