FPV Googles/Mask

Human: HobbyKing sells a low budget DIY FPV mask under the Quanum brand that caught my attention. I liked the concept of using a display with a lens in front of it, as it provides a more immersive experience than traditional FPV goggles and comes at an affordable price. However, there are some issues with the Quanum mask that need to be addressed. The screen has an extremely low resolution, making it difficult to obtain a sharp image. Furthermore, the mask uses a Fresnel lens which makes it impossible to achieve clarity. Fresnel lenses are not suitable for use in close proximity to the eyes, and high magnification reading glasses provide better sharpness but can be challenging to mount on the Quanum mask. There were a few 3D-printed mask designs available online, but none of them allowed for using reading glasses, which is essential for clear vision. They also seemed rather heavy. As a result, I decided to create my own mask from foam and 3D-printed parts. Instead of cutting out the main body parts from foam, I opted to purchase them pre-made from flyingwings.co.uk. The ready-made parts turned out to be of high quality and made from very durable black foam. I highly recommend using these instead of cutting or printing your own. It is possible to use a screen up to 5 inches in size with a 16x9 aspect ratio. I then designed the necessary 3D-printed components for mounting a three-point headband, reading glasses, cabling, and the screen to the mask. I am using a Boscam FR632 receiver and have created a holder for it that can be found on Thingiverse. I used four reading glasses from Clas Ohlson in Sweden, which I modified by cutting the frame. It should be possible to find similar glasses pretty much everywhere. The screen I chose is a 5-inch variant with an 800x480 resolution. This particular screen does not go into bluescreen mode when the signal is low, which is essential for FPV flying. I am providing alternative mask fronts both for the specific screen I used and a generic variant that can be adapted to any screen by manually cutting out a hole to make it fit. The only modification I made to the screen was drilling two holes in the back plate for the cabling and replacing the original clumsy cables with new ones. I created a custom back cover for my particular screen that conceals the cable holes. The headband is made from a 2-inch elastic belt. The total cost of the mask, excluding the receiver, was approximately 60 Euro. My 32-channel diversity receiver added another 60 Euro to the total cost. However, it's possible to find 8-channel 5.8 GHz receivers for under 20 dollars today, which is quite amazing. All parts are small enough to fit on a standard 15x15 printing bed.
