Lightweight DIY Fpv Googles

Introduction: Lightweight DIY Fpv Googles

I wanted to have fpv googles with high resolution screen but I didn't want to spend so much money on ready made one. So I thought why not to make my own out of my phone (Nexus 5) and some stuff laying around. Finally I made handy googles all powered out from phone battery with ability to record flight (and you can publish video to the net immediately!). Also instead of phone you can use laptop and have fpv monitor.

Step 1: What You Will Need:

1. Android phone. I'm using Nexus 5. 5 inch screen work perfectly, If you have bigger phone you may try made 3d googles (more on that later).

2. Some type of googles. Previously I had Quanum v1 so I used them, but you can use Google Cardboard, 3d print or made out of something.

3. EasyCap or some cheap clone. You have to check chip inside of it. Software which we will be using work only with STK1160, UTV007 or UTV382.

4.EasyCap Viewer. This is an app for phone, you have to pay for it but it's worth it.

5. AV Reciver. I'm using RC305, you can buy it from here

6. USB type A to micro USB adapter.

For tools you will need soldering iron, hot glue gun and tape

Step 2: Hacking EasyCap

To make EasyCap lighter we will disconnect not needed cables. Also we need 5v output from it usb connector.

Firstly you have to open cover. Best way of doing this is to put screw driver at side panel and pry. Cover uses four pins to hold so watch out to not break them.

When EasyCap is opened you want to get rid of cables, we need only one it should be yellow, but check the instruction of yours to be sure thats is the AV input (it may be called CVBS in). Rest of the cables cut of and pull out. Best way of disconnecting them from connector is to pry those small pices of plastic with knife and then pull of the cable.

Now it's time to get 5 volts for our reciver from battery phone. To do that I soldered two cables to the usb of EasyCap. To be 100% sure it's correct check out pinout of the usb type A.

You can soldier reciever DC jack directly, but I used xt60 connector, so i can use reciver for different projects.

Step 3: Setting Up the Reciever

If you want you dont have to do anything with reciever, but you can make it lighter and it will heat up slower.

First you need to open metal cover. Unscrew small screws and nut from antenna connector. Inside you have to solder two pins of the step down converter. It should reduce power usage. But when you will use higher volage it will burn out!

Reciver sends AV by mini jack, with reciever you'll get adapter to connect it to EasyCap but it is very long and heavy. Thats why I desolder one of outputs in reciver and directly soldered end of the adapter.

Step 4: Connect Everything to Googles

For mounting I've used hot glue and double sided tape. Well... it's not the prettiest but it work. I'm sure that some of you will make yours much better.

Step 5: Phone Configuration

Just install the app on the phone. In the app go to preferences and select right chipset. Turn on also Car mode, if you want to turn on app automaticly when EasyCap is pluged turn on Autostart. If you pay extra you can use cardboard view. With that you will see "3d" view out from your camera, but remember to use googles with good lenses.

If you want to record flight install some type of screen recorder. I'm using this.

Before flight always remember to charge up your phone and turn on flight mode so noone can call to you (flight mode quite funny isn't it?) also it will reduce your battery usage.

Step 6: Using Laptop As a Screen

For this plug EasyCap to your laptop best way to do this is to use usb extension cable (most EasyCaps have it in kit) for software install VideoView or diffrent capture porgram. It's the same as using normally EasyCap so there are many tutorials how to do it.

Step 7: Finished!

Now you can take your super googles and flight!

And sorry for my english :) I'm pretty sure I've made some mistakes.

    might have to try this for a cheap alternative. I have plenty of old phones lying around.
