FPV Goggles

Former Member

Hi Ben, First Person View Goggles cost over $300 (Example: Fat Shark Goggles) I was wondering if you could make an episode on how to make your own for a reasonable price.

 

Thanks, Myles.

  • In order to keep a decent resolution i was only able to find a 3 inch tft display at 480p resolution for about $140. You then need some optics to reduce eye strain having a display that size close to your eyes so i found a lcd view finder magnifier for a Canon 600D that uses a 3 inch lcd for $10. Now the problem is that is only for one eye and a local hard wired video source. Not to mention we still need to figure out the power source and mounting. Then if we want to make it a "stereo" display and display a image to both eyes you are looking at doubling your cost for your screen and screen optics. You will also need some sort of video splitter to slit the source to the two screens (maybe even find something to choose to split the signal or stretch the signal across both screens if you feed it a sbs video and then you could create a 3d effect). So in order to keep the quality up and the functionality there are a lot of parts and cost involved.


    That all being said a simple solution would be to get NTSC/PAL Video Glasses and reuse parts to fit your needs. Typically they support a 240p lcd micro display for about $100. At these sizes that is below your average resolution. Your iPhone or android that plays 1080p video really has to downscale that video to what your display can actually show (yes even the retina displays), but you still have near 720p on a 5 inch display. That is a lot of pixels per inch and the smaller you get the less pixels you can jam in there.

     

    Those Fat Shark Goggles are really a deal considering the price, resolution, and quality of parts (oh glass lenses). However if you happen to have a couple of 3 inch lcds laying about and a 3d printer just order two of those canon adapters and split the video signal and "slave" the second lcd driver board off the primary so that what you do to one lcd happens to the other (the tac switches to control brightness and what not). Then play with how far apart (left and right) the screens are till your eyes can focus on both of them comfortably. Maybe use popsicle sticks to test it first before making your design, or if you are fancy make your design adjustable. Make sure both lcds are identical otherwise there may be slight difference between the display time (lag between processing video and displaying it).

     

    If you are looking for wireless video for a pov flight then you need a ccd camera (or gopro) hooked up to something that can transmit it long distances. I can't think of anything you could hack off the top of my head but your can get a FlySight transmitter and receiver for around $100.
