An inexpensive magnifier for your FPV LCD monitor. Increase the size of your LCD monitor by about 50%, from a 7" LCD to about a 9" LCD, with little lost in quality. Big LCD image without the extra bulk, weight and power usage. Uses cheap Fresnel sheet magnifier from the dollar store. Better quality Fresnel lenses will improve image quality, however the dollar store ones work just fine. You might also find that Fresnel lens varies a bit in magnification and quality, so happy dollar store exploring to find that perfect one. As with any magnifying lens, do not expose to direct sunlight, or you will run the risk of burning your LCD or transmitter. Fold it back flat on the shade when not in use. Use with care and at your own risk. Enjoy the bigger view! My FPV LCD holder and transmitter stand link: http://www.thingiverse.com/thing:349502Print the base and hinge with 3 solid top and bottom layers, 3 perimeters and 30% fill. Use two 16mm long, 3mm filament as hinge pins. They are friction fitted, so you will need to clean the hinge holes with a 3mm drill after printing. Use a 10mm strip of double sided tape to hold the Fresnel lens to the hinge. Use self-adhesive Velcro strip pairs to mount the base to the LCD shade. For best image quality, use center of portion of the Fresnel lens. For my 7" RC800 LCD, the size is 185mm wide by 110mm tall, cut from the exact center of the lens. I also find the image quality is the best with the grooved surface facing the LCD, smooth surface face outward. Double sided mounting tape to the hinge also sticks better to the smooth side of the lens.
