A laser rifle- a spectacular tool

A German laser weapon hobbyist Patrick Priebe has made a laser rifle which could be one heck of a tool for highlighting. The aluminium bodied 12-lb (5.4-kg) rifle incorporates a 7-watt infrared burning laser along with a 2-milliwatt red aiming laser. The power comes from an 18 V rechargeable battery pack converted to run at 12,000 volts while a 12 V pump circulates one litre of distilled water to help keep things cool. An LCD indicated when the temperature of that water is getting too high the rifle has to stop shooting. It works best at a distance of about 13 feet from its target. A number of applications yet to come from this spectacular maker.

A breakthrough for Sight Loss

Latest News from Cambridge University says, they have been able to successfully print new eye cells which could be used to treat sight loss. The work was carried out using animal cells and it was a success. This opens a new age and hope for people who are affected with sight loss.  

The tests are at initial trials. Most are tests are waiting ahead before human trials. Initial experiments were conducted on adult rats. An inkjet printer was used to print two types of cells from the retina of adult rats, ganglion and glial cells. These are the cells that transmit information from eye to specific parts of brain, and provide support and protection for neurons. Currently the printed cells remains healthy and also retained their ability to survive and grow in culture. 

Even though the tests are conducted on these cells, scientists says that their aim is to use this concept and technology to use in retinal repair in the future. That is, attempt to print cells such as light-sensitive photoreceptors such as rods and cones. They have already been able to reverse blindness in mice using stem cell transplants. I hope this can be a major breakthrough in medical science and I am always inspired and motivated by "what the technology does in the field of medical science".  :)

World's First Camouflage Clothing

You may wonder why I said World's First Camouflage Clothing when we have a lot of camouflage clothing available in the market. Yes, you are right. There are a lot of camouflage clothings available but they are used only for a single camouflage purpose. What if the season changes? There comes the relevance of Cabela's new color-changing ColorPhase apparel. Now wonder why it became the first of its kind. 

According to Cabela, ColorPhase is the world's first camouflage clothing printed with rapid-change, temperature-activated dye. This means based on seasons temperature the colour of the fabric changes. ColorPhase camo will begin changing colours at 65 degrees Fahrenheit. This allows soldiers as well as hunters to blend perfectly with the environment.

Google Cloud Print - Easier life for Users and Administrators

Google have always played an important role is developing web related applications making the life of users and administrators simple and easier. A new technology has been developed which helps to connect your printers to the web. It is called 'Google Cloud Print'. With the help of this technology we can make our printers available for us as well as for others whom we decide to choose, from the applications. This technology works on our phone, tablet, Chromebook, PC, and any other web-connected devices were we want to print from. Google Cloud Print works with all printers, but its always recommended to use a Cloud Ready Printer, since it can give us best printing performance. 

HOW TO SET UP A GOOGLE CLOUD READY PRINTER

It always easy to get start with a printer that's Google Cloud Ready. Consider an example where we try to set up a Canon Pixma MX922 as the Google Cloud Ready Printer. Each printer set up varies, but most of the times the instructions are easier to follow and I do believe you will not have any problems in setting up a printer. 

First we have to connect the printer to broadband or Wi-Fi network and register it with Google through the printer's onboard menu system. It will give us a shortened URL and QR Code which we can use on our phone or computer to log into our Google account and complete the registration. Its always better to finish registration quickly since we have only 14 minutes to do it. After registration is completed, we can go to this Google page to manage all of our printers. There we can see which printers we have, when they were added, the print jobs that have been completed etc. Its pretty a decent brief which can be used in future too. 

ADDING A STANDARD PRINTER TO GOOGLE CLOUD PRINT

If you dont already have a Google Cloud Ready printer, we can set up a regular one. First we have to make sure the printer is connected to the computer and make sure the latest printer drivers and Google's Chrome browser are installed. 

Using Chrome, log into the Google account and go to Settings>Show Advanced Settings. Then scroll under the Google cloud Print section and click the Manage button. 

Here we can see all our printers listed under My devices. Under Classic printers, click the Add printers button. 

For example if we are adding Canon MP495, make sure its checked and Click the Add printers(s) button at the bottom. For convenience we can also select automatically register new printers. 

This technology is easy to be used through mobiles as well as i-pads. There are a lot capabilities that Google Cloud Ready provide us. Some of them are 

• Convenience: Cloud Ready Printers can also register themselves directly with the Google Cloud Print service over the home or wireless network. Since they are connected to the web, they can keep their drivers and firmware up to date. Google Cloud Print also works with conventional non-cloud printers, so that we can start with any printer that we own. 
• Safe: Google Cloud Print takes security very seriously. Documents are transferred over a secure HTTPS web connection. After the job is completed the file is automatically deleted from the servers. In addition we can also delete jobs and their history, at any time. 
• Share with you friends: Google Cloud Print allows you to share printers with friends, family and co-workers. We can also track the jobs done by these printers, share with trusted individuals etc. 
• Chromebook ready and Enterprise ready: Google Cloud Print is the standard printing technology used by ChromeOS on Chromebooks. In the enterprise level, the Google Cloud print is used on over a thousand printers. It can meet the organization's requirements easily. 

At the end I would say, the Google Cloud Print makes the life easier of both system administrators and users. Not only that, less headache for organizations. :) :D 

A new promise for Electronics

Comparison of graphene oxide before (left) and after (right)

A team of researchers from MIT and University of Berkeley have found a new simple inexpensive method for a variety of applications. 

Do you wanna know the Hero of the Story? :) Yes, Ofcourse. Its Graphene, a two-dimensional array of carbon atoms. The new method was published in Journal Nature Chemistry  which was co-authored by MIT students Priyank Kumar, Neelkanth Bardhan and MIT professors Jeffrey Grossman and Angela Belcher and other two authors from Berkley. 

In fact, pure graphene lacks some key properties needed for electronic devices, solar power and sensors. But when it is modified through the addition of oxygen, it can provide all the essential properties required. The group did a new approach in which they exposed the material to relatively low temperatures. But the key point is, they havent used any chemical treatments. The low-temperature annealing process itself modified the distribution of the oxygen atoms, causing them to form clusters and leaving the areas of pure graphene between them without introducing any sort of disorder to its structure. The material earns a lot of capabilities such as ability to absorb visible light, becomes much electrical sensitive and further more which can be used in wide variety of applications such as solar cells etc.
