The thought of having your smartphone perpetually tethered to a power source is a terrible idea, no matter how awful your handset's battery life might be. But here it's actually a pretty clever idea. The micro filament that keeps this drone tethered to a base station is considerably thinner than a headphone cord, and it not only provides a limitless supply of power when the controller is connected to a permanent power source, it also allows the tiny drone to send back hi-res HD video without lag or stutters.

It also makes the tiny hexcopter completely unhackable, because there's no wireless signals to intercept or compromise. The tiny pocket-sized drone actually carries a spool (about the size of a quarter) of about 250 feet of the micro-filament tether onboard itself, which it feeds out as it moves forward, ensuring the wire doesn't get snagged along the way which would limit its progress.


With a fully-functioning prototype under its belt, the folks at Cyphy Works are currently in development of a production version of the drone. But don't get too excited about getting your hands on one yet. The company is actually working to develop the drone for military-use, giving soldiers a safe and compact reconnaissance tool they can easily carry as part of their standard kit.
