Want a drone and can't afford the crazy expensive models? Well, Bitcraze has you covered with their new quadrotor drone that measures just 4-inches across. This pint-sized drone is extremely extensible due to the use of open-source code and components. The best way to let you check out the drone is with the following video:
It's small, which allows it to be used indoors. This is something you can't necessarily do with larger drones. Another benefit of the small size is that it makes it safer to use. It's pretty hard to do much damage with something as small and light as the Crazyflie Nano.
Pre-orders for this awesome little drone are up on Seeed and will set you back $149. If you want a more advanced drone with more sensors, you can pick up the $173 version that comes with a magnetometer and altimeter, which could be useful for flying without actually looking at the drone.
