ESP8266 operates at 3.3V and consumes around 100mAmp current, for designing of its power supply you can use LM1117-3.3V Low drop out (LDO) linear regulator which is having current capacity of 800mAmp. Remember that, this regulator is low drop out regulator. It is better to give 5V as input to the regulator to avoid over heating of regulator. You can create small heat sink on PCB using copper area.

Getting Started with IoT
Introduction
Extending the current Internet and providing connection, communication, and inter-networking between devices and physical objects, or “Things,” is a growing trend that is often referred to as the Internet of Things.
“The technologies and solutions that enable integration of real world data and services into the current information networking technologies are often described under the umbrella term of the Internet of Things (IoT)”

2. Selecting right IoT wifi module?
3. How to program ESP8266 using Arduino IDE?
4. IoT Software configurations.
5. Which tools to select ?
IOT based home automation project
We live in an exciting time where more and more everyday items “things” are becoming smart! “Things” have sensors and can communicate to other “things” and can provide control to more “things”. The Internet of Things, IoT, is upon us in a huge way and people are rapidly inventing new gadgets that enhance our lives. The price of microcontrollers with the ability to talk over a network keeps dropping and developers can now tinker and build things inexpensively. Continue reading IOT based home automation project
