In this post, I’ll show you my DIY FPV goggles. These obviously aren’t as good as proper FPV goggles but they are cheap, they work and I was able to make them out of things I already had at home.

I made these out of an old 5,8Ghz video receiver, a VR headset for smartphones, a USB video capture card and my smartphone.

The quality of the picture will be greatly dependent on the PPI(pixel density) of your smartphone’s screen it will essentially drop by half as you need to squeeze two images onto your screen. My phone has a PPI of a bit over 500 so the image that you see through the goggles is around 250 which isn’t that great.

The delay of the video is a bit more than 100ms which is not good enough for any high speed FPV flying but it’s good enough for just casually flying around.

The 5.8GHz video receiver gets powered directly from the 3S battery. I also  added a step down converter to lower the voltage of the battery to 5V which I can then be used to charge the phone. The video output of the receiver gets fed into the capture card which is connected to the phone via an OTG(on the go) adapter. Finally, I installed an app on my phone that displays the video from the capture card on the screen as two images.
I glued the receiver to the front of the VR headset, attached all the cables, battery and capture card with velcro to the head straps.
