Each week we will usually have 2 practical and 1 theory class. Pupils are expected to do both practical and theory tasks for homework. Therefore, pupils must have access to a computer with Microsoft office 2007 at home or in boarding. They must also bring a portable storage device to class to take work from class to home.

Printer produces personalized 3D chocolate”
Chocolate lovers may soon be able to print their own 3D chocolate. A 3D printer uses a chocolate by printing the layers of chocolate instead of ink or plastic. 3D printing using plastic and metal is already used in industry to speed up design work. Chocolate printing, just like any other 3D printing technique and 3D shape will be produce by layer to make it thicker and thicker to form 3D. Once a layer is completed, it becomes solid, and the machine moves on to the next layer.
The chocolate printer is like a food printers. This machine builds up objects layer by layer. Getting the printing process right involves careful control of key parameter, such as temperature. Once the original one becomes a finished product, it may find a role in the restaurant and food preparation industry. So the customers able to design any object they want on a computer before hitting the print button.
Besides producing 3D chocolate, the further step is to take their printer into cyberspace by creating a chocolate-oriented website. So we will be able to put digital technology with a chocolate (e.g. social network)

Summary of “Bringing art to life in print”
The world’s most advanced printing technology. Masterpieces in a life-size production has unveiled across central London. Hewlett Packard used the new technology called DesignJet 10000 that was designed to display National Gallery’s Grand Tour. It prints on a new vinyl called Epiflex. HP says that it includes waterproof laminate; the vinyl will make the colours last for three years. They were reproduced by Electronic Printing Services in Leeds. Steve Farley said he looked for a printing machine that could print a picture containing billions of pixels at a high resolution. The largest pictures cost around £200 each to reproduce. However, other industries are not so convinced by HP’s product. Dr Sean Smyth said that Hewlett Packard’s technology was advanced but it was less versatile than at least one major competitor. He considered Epson Stylus 9600 to be most suitable because it used pigmented, or dyed, ink rather than ink made up of solvents. Solvents increase the cost.
In these day the technology is turning a ream paper into an Adobe form
people mostly uses Adobe for information instead of a paper. Another way for get rid of the paper is to scan from the paper into a document, which means less chance of wasting paper in the office. Not just the big business that use the scanner, the small business also did.
Diana Helander said that even we use the document instead of paper it doesn’t makes it necessarily any easier..
Office printers ‘are health risk’
There was a investigation that almost 1 in 3 of the printers produce large level of toner in the air.
some tecnolgy science want that printers compayny to tell their customers with health warning, because they caused alot of health problems such as infiltrate the lungs and respiratory irritation to more chronic illnesses.
some researcher called the governtment to regulate the air quality in offices and they also want the companies to put thier printers in a suitable place.
Thin speaker offers ‘crisp sound’
- The engineers claim that the new ulta slim speakers looks ood but it has crisp sound, the loud speakers could use in many conditions such as in shopping malls, passenger terminals and speaking poster to deliver adverts.
(FFL) the FLAT FLEXIBLE LOUD SPEAKER- Warwck university professor Dr. Duncan Bilson used a piece of tin foil and some baking paper. (Those are the materials that produce sound)
The FFL speakers is diffrent from the traditional speakers is that Traditional speakers work by converting an electric signal into sound and FFL speakers stimulated by an electrical signal it moves air as a bulk mass
“Printers produce copies 3D”
Several companies are working on developing low-cost three-dimensional printers which could eventually find their way into the home.
This printers can produce more than hundreds per days.
Sony, Adidas and BMW are using 3D printer technology to create prototype models as it is faster and less expensive.
Mr. DeHart said that the technology could make it to the High Street, with printing shops offering 3D models as well as conventional photocopies.
Summary of “global data storage calculated at 295 exabytes”
The calculation of the amount of data that has been stored by peoples from all over the world by 2007 is 295 Exabyte which is equal to 1.2 billion average hard drives. This was calculated by estimating the amount of data held on 60 technologies. Computer storage traditionally measured in kilobytes, then megabytes, and now usually gigabytes, then terabytes, petabytes, and then exabytes. (One exabyte is a billion gigabytes.)
The survey covers a period known as the “information revolution” the human society changes through time. It shows that in 2000, 75% of stored information was in an analogue format and people in the developed world could communicate eight times more information than people in the developing world, but that by 2007, 94% of it was digital and the gap between developed world and developing world has nearly doubled, and people in richer countries have 15 times more information carrying capacity.
The fastest growing area of information control has been calculated. During the past two decades the survey shows that the global computing capacity increased by 58% per year.
Mr Golding, can you post the question that we need to do for homework for me because i thought that you will post in on the blog so i didn’t write it.
I read an article about how robotics are being applied to the battlefield. For example, robots are deployed to defuse bombs, and even for aerial surveilance. The U.S military states that a third of its military will be replaced by robots by 2015. This is quite improvable. Robots such as TERMINATOR have still a long way of development to become reality.
Criminal hackers have found the latest generation of online banking security devices given out by banks.
After logging in to the bank’s real site, account holders are being tricked by the offer of training in a new “upgraded security system”. Then money is moved out of the account but this is hidden from the user.
Experts told customers to follow banks’ official advice, use up-to-date anti-virus software and be vigilant. Devices like PINSentry from Barclays and SecureKey from HSBC – which look like calculators – ask users to insert a card or a code to create a unique key at each login about 30seconds then cannot use it anymore.
Even there are chips and pins devices make the hackers’ job more difficult, the hackers themselves have raised their game.
I had watch bbc click about how Computers help artists at Sweden’s ice hotel.
They use computer edit design software by loading in the design they want to let the computer make a 3D piece of art but it can make to a certain size so people still be needed to build the ice hotel. This help them to see how it look before they really make it which mean they will use less time making it. Also it use to control the power and light in the hotel.
This is about the “Hackers outwit online banking identity security systems”, by the criminal hackers have found a way through an online banking security devices given out by banks.
After the criminal hackers logging in to the bank’s real site, an account holders are being tricked by the criminal hackers.
The criminal hackers then ask the users to insert a card or a code to create a unique key at each login, valid for around 30 seconds, then its cannot be used again.
Headphones ‘made to fit in five minutes’
is about to make ear canal shape from a machine that change the silicone shape and when people wear it the small balloons will come out and make a fit shape of ears canal. It take only 5 mins and you are not allow to talk while you are using that. That is for people who have small ears and the normal ear phones are not fit in and keep falling off.
