Do the milkshake the milkshake do the shake
How about using that Bluetooth PlayStation controller to navigate a teeny tiny little quadrocopter? It's not like you can use it for much else, these days...
This chopper is called CrazyFlie. It weighs just 20 grams (0.7oz), and is a mere eight centimetres across (just over 3"). It uses a printed circuit board, an onboard Cortex-M3 CPU, and an assortment of gyroscopes, accelerometers and rotors to keep it in the air.
...and it's really very awesome, in case you needed further convincing.
The CrazyFlie has been in the works for over a year now, at Daedalus Projects, who have posted all the quadrocopter's details on their blog. Apparently, the most expensive part of the project were the motors and propellers - Daedalus actually cannibalised the parts from RC planes that were bought separately. If you're thinking of doing this one yourself, try to source those parts directly.
The original plan was merely to get a piece of circuit board to fly - I think the intention may have moved onto bigger and/or better things, as the team continues work on the next version of the copter.

I like video games and music and cups of tea and noodles and beagles and colour-cycling LEDs.
