The last part ordered was the FPV Camera and that operates at a voltage of 12v. Since I will have a clean 5v provided from the video transmitter (to be selected later), I need a 12V step-up voltage regulator.

What makes the quadcopter I'm building different than say a DJI Phantom? Well, the main difference is that I'm building a FPV (the First Person View) quadcopter and to achieve the FPV part you need at least one camera (I'll be installing two, one for the FPV and the other to record HD video -- more on that in a later post). The FPV camera broadcasts via a transmitter (will be selected in another post) to the ground station which can either be a simple video display with a wireless receiver or video based goggles (also to be selected in a future post).
The video from the front mounted camera is what you will use to fly (or steer) the quad in the air without needing line of sight view -- you see what the copter is seeing. The video signal also has superimposed telemetry data (via the OSD module). As this is technically the "eyes" of the copter it's important to have a high quality camera that has a high dynamic range and provides clear sky and ground exposure.
Here’s a neat add-on that turns your iPhone 4 into a HD video (audio) recording rig at a fairly economical price of $150. The key feature of the Fostex AR4i is that it brings excellent quality stereo audio recording via the dock connector and it’s built-in AD/DA converters. The included microphones can be swiveled and located in many different configurations giving you the best possible audio capture. Built-in LED input level metering, gain control and headphone monitoring, the AR-4i has been designed to turn your iPhone 4 into a high-quality audio and HD video capture device. This little add-on is great for trips and family events where you don’t want to carry another device just for video capture, but want the higher quality audio and video stabilization (via form factor and included handle).
