Second - The FPV Rig

The second part of my project includes the building of an FPV rig that I could attach to the quadcopter that I had built.

Here is that diagram again about how I wired it.

And in the end, here is what I had built...

I mounted it on some foamboard, but should have found something thinner.  Anyway, I power the FPV rig from a separate battery for now.  It adds significantly more weight but is convenient for testing.  I will have to research a compact and lite solution for filtering the motor noise when I choose to use one battery.

The total cost of the rig is about... $35.

• Camera $18
• Voltage Regulator $6
• AV Transmitter $11

Of course with a $19 AV Receiver the price goes up to $44, but is still inexpensive.

Camera

• 170 Degree Field of Vision
• Runs on as low as 3.3 volts (so can run directly from 1S)

Voltage Regulator

• Polulu Step-Up/Step-Down 3.3V Reglator
• Really just needed a 3.3V stepdown

Video Transmitter

• TX5823 Operating on the BOSCAM bands
• Runs off of 3.3V
• 200mw

Video Receiver

• RC805
• Runs off of 5-12V
• Two Video Outs (2.5mm 4-pole plugs)
