IoT Projects - ESP8266 [wiring]

My apologies in advance if the diagram below isn't all that proper, as mentioned before, I'm a bit of a newbie when it comes to wiring circuits...!

Anyways, the important bits to grasp here are:

1) the ESP will handle 3.3v max - going beyond that will most likely damage it
- using a 3.3v voltage regulator to ensure that the voltage being delivered to it is correct

2) the LED strip is represented by the LED on the upper part of the diagram
3) the case fans are represented by the LEDs on the lower part of the diagram
4) a couple of relays are required for wiring the fans and LED strip - and those are 5v relays, so another 5v voltage regulator is required
5) the case fans run at 12v
6) a single power supply is being used: 12v/1A
7) the wifi module's purpose is to control the relays using its two available GPIO pins, by processing MQTT messages from the broker (see previous posts on MQTT and Cubietruck)

Parts list follows:

IKEA Dioder LED strips
5V voltage regulators
3.3V voltage regulators
12V 1.0A Power Supply
5V Relay Module Board Shield
120mm Quiet Case Fans
