Scientists in Spain have successfully tested a wheelchair controlled entirely by your mind.

It works by presenting a real-time 3D image of the surrounding area on a screen in front of the user. To steer, the user concentrates on the area he wants to navigate to, while a cap reads his brain activity and transmits the information to a navigation system.
It's a far less mentally exhausting system than previous versions, with the chair doing all the work once the location has been chosen. Thanks to the inclusion of laser sensors, it's able to avoid obstacles in the way, too.
So far, the prototype can only handle two thoughts every minute, but expect more sophisticated models in coming years.
More Weird Tech this week
Earlier this week one eBay seller proved handsfree tech is "as old as the hills". His Nintendo Hands Free – a giant controller for the NES that straps to your chest, allowing you to control the adapted D-pad with your tongue – went for a whopping $540 on Wednesday.
In other news, physicists believe that warp-driven spaceships of Star Trek fame could one day be possible. Developing the travel tech will be no easy feat, however, with scientists searching for a way to move "space-time". Don't hold your breath…
One flying object that has made it through manufacture stage is the world's tiniest helicopter. Weighing in at a minute 0.5g, the PD-100 Black Hornet "nanocopter" fits in the palm of your hand and could provide future soldiers with "battleground intelligence at the flick of a joy stick" (providing it isn't too windy, of course).
Meanwhile, forget cameras and MP3 players – it seems projectors could be the next must-have accessory for your mobile, thanks to a partnership between laser-maker Corning and projector designer Microvision.
Trumping Samsung's Show, the embedded tech is laser-based, so it doesn't need optics to focus at different lengths, allowing 100-inch images to be displayed on any surface – no matter the distance or angle.
Is showering standing up all a bit too much? You want to try real bathing, the HydroGlass way. Complete with seven shower heads, the luxury device lets you shower lying down – on top of a fish tank, naturally, for added tranquillity. Optional accessories include a heated aquabed and soft warm water mattress.
In health-related news, a new wireless asthma inhaler brought the breathing device firmly into the 21st century on Wednesday. Adding IR and Bluetooth capability through a platform called Vena, the tech should help keep doctor and patient more closely connected.
One fan took his enthusiasm a little too far this week, posting a "dangerously awkward" video of his homemade razor-sharp Wolverine Claws deep in combat with some cardboard. Sadly, the video's since been pulled, so we'll never know who came out on top…
