Yes shrinkage is a problem for many at Cambridge University
And sometimes it’s so quick it’s un-satisfying…
That is what happens to a led crystal (Gallium) nitride when you grow it at 1000°C on silicone.
Because the silicone shrinks too quickly after being heated it has not been used to grow led crystal like many other electrical equipment Because the led merely cracked and was not useable but now a man from Cambridge University’s centre for gallium nitride has stepped in with a solution. Now layers of aluminium gallium nitride are thrown into the design and now well in a nut shell it works. We have been told we can expect to see the results of this advance in 5 years.
Don’t hold your breath.
100,000 hours of light is over ten times longer than the energy saving bulbs we currently have screwed in.
Now a 15” thin slice of silicone will come to around 15£ but only that can grow up to
150.000 led crystals that will be a lot of cheep light for every one.
Light may not be cool or very interesting, however I believe that a small advance such as this is still a marvel in its own right.

hay..nice legs

In Japan there are so many technological advances you couldn’t shake a mechanical fist at them, water activated batteries and Printers that can erase.
There are many gadgets that have surfaced and a popular device is now floating to the top of the tech sea.
Robot leg development has been around since 1999 and over the years researchers have developed a number of different types of robot legs, some can seat disabled people and are controlled by the user via an interface, some require the user to have some mobility in there legs to use the machine and others can be controlled by a brain, animal or human.
Honda, as you know is a car manufacturing company but what’s this…Honda robot legs? Now just because Honda made them, unfortunately they will not let you run at a ridicules speed and will not allow you to leap tall buildings and a single bound or small ones for that matter, however it will assist the wearer to walk with ease provided you can already walk. People that have a lot of trouble walking will be allowed to move with ease.
Matsushita Electric in 2007 developed a set of chunky robot legs aimed at the same market but the reverse jointed and all importantly, impractical price of $127,000 makes them look very unappealing, however will still give a user mobility if they have deep pockets.
In military applications there has been development since 2005 to devise combat robots. The robot will have six or maybe eight legs all working in unison to achieve remarkable agility and speed.
The robots will also be laden with weapons and controlled by several A.I controllers. The development deadline is some point in 2011 and such development reached a news paper called the Korea times.
There is many other types of mechanical legs some very difficult to replicate and example of some robot movement is shown on this link

Everything I have written is true to the best of my knowledge.
The next post will include a very practical device and the instructions on how to make it, find out next post what it is.

Shiny pretty lights
In a day and age where almost every house has a computer or television and where some people just find it so relaxing to come in after a hard days work and look at pretty pictures of flashing lights and shiny bright colours there might be something lurking around the corner that will knock the socks off all you couch potatoes out there.
Imagine you’re watching the laundry getting angry with a poor student in the boogie man on your computer, at that moment a nice man from a MIT research facility who has dropped in for a pop tart and non alcoholic beer, plugs a small device into your computer and all of a sudden the laundry is getting freaky all over your desk top.
A holographic video display is an amazing idea and a wonderful concept, however it’s quite expensive and not every one has space for a large hologram projector but now the lovely brains at MIT have turned a laboratory-based holographic display system that cost many, many pennies into a device witch will be compatible with high end computers and home entertainment centres by squishing and squashing the over sized and complex machine into a plug in??
Tasty...
Now if you are not the person who likes to play computers games or watch hours of television then here is another tasty cookie for you, this technology could give doctors and surgeons alike another way to view medical images like MRIs and CT scans, sets of really Confusing multidimensional data and designs for cars and pretty much anything else that need a pretty picture to show people how it’s made.
I am a games monkey myself and I personally would love to see fall out 3’s vicious combat system in all its AB- splattering glory.
