Low-Cost 3D FPV Setup for Micro Quadcopter

We can all agree that, as 23456andi, the creator of this project puts it, “FPV is a pretty cool thing.” And since you already have a pair of goggles strapped to your head, it seems only natural that seeing things in 3D would be the next step towards total immersion. Unfortunately, cameras capable of this on the market today are too heavy for a micro quadcopter, and you’ll need to shell out quite a bit of money for a pair of goggles anyway.

Not taking “no 3D” for an answer, Andi went to work designing a custom circuit board to fuse the input from two FPV cameras together. Along with the electronics, a camera mount was 3D-printed, fixturing the cameras over top of the rotors that lifts them into the air.

The combined signal is then transmitted over the air via an FPV transmitter, and displayed on an Android headset using a video grabber and custom app. Notably, the build was made for under 70 Euros (or around $85 USD).

You can see a test of the setup in the video below, showing off the app’s wide variety of adjustment options. While a micro quadcopter is an excellent use for this configuration, there’s no reason that it couldn’t be applied to other robotics projects, perhaps even allowing you to add 3D FPV capabilities to your next robot!
