So you have got a spare phone that you wish to put to good use? Why not use it as the brain for a personal drone? The PhoneDrone lets you do just that. It turns your smartphone into an autonomous aerial camera and does not cost a ton. You can pair your drone with another smartphone for control and video streaming.
As you can see in the above video, the PocketDrone carries your phone with your drone. You can shoot straight down or forward. PhoneDrone has arms that can be closed, so you can carry your drone around easily. The companion app runs on iOS/Android devices. You can find out more about this on Kickstarter.
