Also consider using the ESP-12 (also called an NodeMCU when it includes the Lua code) instead, which is more forgiving with power.

** Examples

*** "One Way Chat, part 2":https://www.youtube.com/watch?v=iRMdj3dS2hc shows how to connect basic hardware (somewhat limited) and program to run as a web server using stock programs.

*** "HTTP I/O":http://www.instructables.com/id/ESP8266-HTTP-IO-Server/ is a "library":https://github.com/jscottb/ESP8266_http_io that gives direct access to GPIO pins.  This is essentially what we'd want except it needs to be "wrapped in a security layer":http://www.esp8266.com/viewtopic.php?f=23&t=3929 of "some kind":https://github.com/mziwisky/esp8266-dev/blob/master/esphttpd/user/auth.c.

h1. AC Control

# TRIACs: Low cost, high current handling capability. 

# Traditional relay: moving parts, relatively low cost, very high current

# Solid State Relay: Higher cost, no moving parts. Advantage over TRIACs is that SSR can interrupt current at any point in the AC waveform. TRIACs only cut off current at the zero-crossing point.

h1. DC Control

TBD
