In this Instructable I am going to tell you how I built a cheap FPV Virtual Reality system for my quadcopter with basic parts. My project started to became more and more difficult here so I thought it would be nice to make a simpler project too for the beginners. You just have to solder a little bit and you will have an amazing Virtual Reality FPV system.
When I wanted to buy a new VR FPV Reciever I saw the prices, and I thought to myself that I can built a cheaper version for personal uses. So I made one... It uses the RunCam Swift 2 camera onboard and transmits 5.8GHz video signals that can be recieved by a 5.8GHz reciever. With a $7 gadget we covert the analog video signal to digital and then connect this little device to our smartphone. Simple, cheap and high quality.
Here is how I did!
Step 1: Video
I made a small test video for you about the project.
Step 2: Gathering Parts
I bought the parts from different places. I tried to find the cheapest sites, here are they!
- Soldering Iron
- Wire Stripper
- RunCam Swift 2 Camera
- Virtual Reality Glasses
- FPV Transmitter and Reciever
- Smartphone (I used Android)
- OTG Cable
This is all you need for this project. It is good to have some experience in soldering, but it is not necessary. I have put my setup on my quadcopter but this Instructable is not about the drone. You can apply anywhere in your RC car, helicopter or plane.
Step 3: Setting Up the RunCam
Why I choosed RunCam?
When I decided that I am upgrading my camera system on the quad I watched many other FPV cameras on the web, but none of them had the quality of the RunCam, neither in image quality nor in design. So I said I give it a try and it is very good to use the RunCam. Gives a sharp image has sensors inside, measures battery voltage without external OSD-s and displays this in real time.
First I fixed on its mount that comes with it then simply soldered to the video transmitter. Just three wires: Yellow to Yellow, Black to Black, and Red to Red. These are universal so you can't really miss it.
Step 4: Mounting on the Drone
I used two zip-ties to mount my camera on the front of the drone. I actually like to see the propellers when I do FPV so I set the angle this way. It is good because I know how close can I go to an object.
Step 5: Quick Test
Once I fixed my camera I tried it out. Worked fine, I am explaining in the next step how I did it.
Step 6: Building an FPV Glass
An advice: you can try with a cardboard VR glass, because it is hard to fit the parts nicely on this plastic one. I used 3mm double sided tape to fix all the components on the VR glass.
- First glue your receiver on the top so the antenna can easily see the signals.
- Next to it place the EasyCap Conveverter (this is a USB converter gadget for this case)
- Plug in your OTG cable and the analog signal cable.
- Place a small 7.4v battery on the left side to balance the other components.
- Power up your device, plug into your phone.
- Enjoy VR FPV
Step 7: Test Before Flight...
The RunCam Swift Manual has a lot details for you about calibrating. Once you set it up you can try it!
Step 8: Thank You for Watching!
I hope you will enjoy using this kind of FPV systema and thank you for watching!
