I made a quick and dirty homemade iPhone Sun Visor for the DJI Phantom controller, and I was very surprised how much of a noticible difference it makes using a visor in sunny days...works great! Used an old watch box that I didn't need, and cut 2 slits on the back so it can easily slide onto the 2 smartphone spring jaws. I kept the right side open so it can swing open and closed, so you could touch the screen easier when needed. Need: 1 small box, scissors, and black duct tape. Time: 15 min Cost: $0.00 Some photos, for those who want to make one yourself. enjoy!
