#84706 Ok. In the mean time here's some stuff that responds directly to what you asked:

Just Google either "build wifi controlled outlet" or "esp8266 wifi switch" and you will find dozens more that also include packaging and power supply ideas.

Check out Amazon or e-Bay and you will find exactly what you are planning ranging from $5.00 to $20.00, but that, of course, isn't as challenging, as time consuming or as much fun.

Also, the NodeMCU ESP8266 has a built-in serial to USB converter that you are going to need.
