Crazyflie Nano Quadcopter
It might not boast a camera or any on-board weaponry, but if you've been itching to hack around on your very own drone, the Crazyflie Nano Quadcopter ($175) should fit the bill. This open source kit features a tiny Quadcopter with an on-board 32-bit processor, accelerometer and gyroscope to keep it afloat, a compass and altimeter for, well, whatever it is you'd like to use it for, a lithium-polymer battery that recharges via micro-USB and provides up to 7 minutes of flight time, and a 2.4 GHz radio that communicates with the USB transmitter, which you plug into a PC to provide control. What you do with it — and even what you could do with it — is entirely up to you. [via]
