This is an awesome homebrew laser-triggered camera rig that is uses to capture amazing pictures of insects in flight and splashing drops of coloredwater.  Fotoopa (creator) makes the compelling claim that no digital camera has the shutter speed necessary to do this kind of imagery.

Control wheelchair using your thought

Wheelchair control by power of thought

Remember Professor X from X-Men who is able to control his wheelchair by just using his mind. And this is going to become reality as scientists at the University of Zaragoza have developed a wheelchair controlled by the power of thought. The chair is equipped with a laser sensor and a screen to display a real-time virtual reconstruction of the surroundings. Sensors on the wheels keep track of the chair’s position as it moves.

Due to each person’s pattern of brain activity is different, the chair needs time to adapt to its user. The device was tested by five volunteers, they were all able to control the chair with their thoughts alone after just 45 minutes of practice. There is still a lot of limitation to this invention so it still under going developing before it go into commercial production.
