The FAA launched its online drone-registration program in December. It requires all pilots, even hobbyists, to register their robots by February 19th -- it will generally cost $5 per registration, but the FAA is waiving this cost through January 20th. Information in the registry will be public record. In the program's first two days, the FAA collected 45,000 registrations.

The teensy Vidius drone may appeal to those who don't want to deal with federal paperwork before flying, though it does have limitations. Pilots can stream a live video feed from the 'copter via WiFi, though it has a flight time of just five to seven minutes on a 20-minute USB charge. Vidius comes with a 2.4 gHz controller, and users can pilot it with a smartphone or tablet, as well. Vidius is up for pre-order now with a ship date of January 29th at the latest. It's on sale for $75 before January 7th; afterwards, it'll be $95.

A tiny drone could be a nice way to have a little -- and we do mean little -- fun.
