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. Monitor (Home automation server)
* "WD PiDrive":https://www.wdc.com/products/wdlabs/wd-pidrive-foundation-edition.html - will be used to store video from cameras.
* "GungHo PiDrive":http://gungho.io/product/pidrive/ - about the same price but directly attaches to the Pi. Might not have the power savings provided by WD PiDrive.

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.
# "Step-Down Converter":https://www.ebay.com/itm/3-3V-600mA-AC-DC-Power-Supply-Buck-Converter-Step-Down-Module-2-5-W-/352515657771?_trksid=p2349526.m4383.l4275.c1#viTabs_0 - AC to DC 3.1V-3.5V.
