802.11n finally official

At last, the long suffering 802.11n draft standard has been made official, and is released from its draft prison with the IEEE finally ratified the latest longer range, higher speed version of the wireless standard. This move took a good seven years since the process kicked off, and a couple of years after the final draft was approved with a slew of hardware companies following suit by releasing 802.11n gear to the market. Makes us wonder what took them so long to review and approve this standard to move it up from draft. Well, all said and done, we would like to give the old proverb a handshake as it tells us “better late than never!”

Touchable Holography? Almost.

It’s cool enough to have holograms, but what if you could actually touch them? This was a project that some researchers at the University of Tokyo took on, and have achieved some interesting results.

You can watch a video of what they have done after the jump, but here is a quick summary. First, they used two Wiimotes (yes, Wiimotes) to track a holographic object in realtime and space. So when that hand that you see in the picture tries to dribble that tiny ball, it responds like a real superball would.

Ultrasounds are then given so the hand can actually “feel” the impact. Experiements have shown that the ultrasounds can disrupt things from a distance, and if focused properly, they can create a sense of touch. At the end of the video is that hand underneath some raindrops, and it can apparently “feel” them.

This is definitely one of those “this could change everything” technologies, but it is still in its fetal stage. In other words, don’t be dreaming about having your own holodeck from Star Trek TNG anytime soon. By the way, I believe that technology used energy and matter conversion.

Man, I am such a geek sometimes. I’ll prove it yet again by saying that this technology reminds me of a short-lived show called Automan. It was about a guy who created a holographic man who others could actually feel. He even had an Autocar and Autoplane which were also tangible holograms.

Yeah, we are a long way holograms that we can feel. I suppose if they had this touch holograms in Star Wars, then Luke Skywalker could have felt Princess Leia saying “help me Obi-Wan Kenobi”.

Oh, that is so wrong.

Chinese Man Makes his own Helicopter

I realize that normally we devote our articles to products you can actually buy, but the story behind this man’s helicopter is flat-out amazing and inspirational to us all.

Wu Zhongyuan is a 20 year old farmer who, ever since he was a child, dreamed of not needing to climb mountains anymore. It would appear that he found his remedy by creating his own flying machine. Wu used principles that he learned in middle-school physics and other relevant knowledge by surfing the Internet on a mobile phone to create this helicopter.

The blades are made from Elm tree wood, and a motorcycle engine provides the power. The frame is reinforced with steel pipes, and he claims that his single-seat copter can fly up to 2,600 feet! Believe it or not, he assembled this DIY helicopter for just $1,600.

This is one of those stories that I really hope is not made up. After all, who hasn’t had a dream and desired that it take flight? Mr. Zhongyuan doesn’t sound like he had a major corporate sponsor, just vision and ingenuity.

Sadly, the Chinese government won’t let Wu fly. I’m pretty certain that the FAA probably wouldn’t let an American inventor fly their own helicopter either, but the fact that someone could do so much with so little just inspires me, really. Kind of makes you wonder what you are doing with your life, doesn’t it?
