Gun Online From 3 D Printer

As the Gun Control issue is raging in the US, to do it techies have developed a Gun from 3 D printers from Computer files!

Gun from 3 D Printer.

A Gun developed by a group of techies from 3 D printers almost entirely from  3 D printers went Online.

Demo of the Gun.

 

 

“

Cody Wilson, founder of Defense Distributed, an organization dedicated to making it easy for anyone to 3-D print their own gun. It’s the opening line of a video showcasing Defense Distributed’s successful employment of a 3-D printer to manufacture a plastic high-capacity ammo clip for an AR-15 rifle.

Wilson is namechecking Democratic House Majority Leader Nancy Pelosi’s call for a “new conversation” on gun control in the wake of the Newtown, Conn., massacre. Wilson follows up his question by firing off a few rounds of ammunition, giving his handiwork an admiring look, and declaring: “Welcome to the age of the printed magazine.” The screen flashes a message: “Download your mag today.”

The 51-second video closes with Wilson eating a meal. An off-camera voice asks him: “So how does it taste?” His answer: “Tastes like Dianne Feinstein’s lunch.” It’s another anti-gun control broadside, a slam against the Democratic senator who plans to introduce legislation that would reinstate the ban on selling high-capacity ammunition magazines that existed from 1994 to 2004.

Wilson’s message could not be more blatant. In the age of cheap 3-D printers and open-source, easily downloadable design code, he is declaring that gun control is obsolete. So don’t even bother trying.”

How to make guns from 3 D Printer.

“But technologically, it’s still simple. That’s because the principle behind a gun isn’t too tricky: load a bullet into a reinforced tube, and whack the back of it hard. That’s an engineering problem street gangs in the 1950s managed to solve with wood, antenna housings and elastic bands, building “zip guns” to shoot at each other; and it’s also the basis for converted air rifles and cap guns. The difficult stuff – getting it to fire accurately, repeatedly and without jamming or blowing up in your face – is still a long way off for 3D printers. And even the best 3D-printed gun still relies on someone else to make the gunpowder.”

See What You Can Not See Insect Camera

I recently posted an Article on ‘We Have more colors Than we See’.

I mentioned there that there are infinite colors and we see only seven because of our limitations.

I found an interesting article on the same subject to-day.

A new Digital Camera developed mimics Arthropods, has 180 Degree vision.

It provides the entire field of view. By contrast, our eyes can only see a narrow angle ahead of us, and the images they form are only sharp at the very center of our visual field.

Digital Camera, based on Insect’s Eyes.

“Arthropods—insects,spiders and their kin—have compound eyes, which consist of hundreds or thousands of individual units or ommatidia. Each one has its own lens and light detectors. They form separate images, which are then united in the brain. And since arthropods greatly outnumber all other animals, the vast majority of eyes are compound ones.

Now, John Rogers from the University of Illinois at Urbana-Champaign has developed a camera that mimics compound eyes. It might not have the same resolution as a state-of-the-art digital camera, but it compensates with many advantages that make it ideal for surveillance. Perhaps in the future, we’ll be watched by man-made flies on the walls.

Rogers chose to mimic apposition eyes—a type of compound eye where each ommatidium sees a narrow part of the insect’s visual field, effectively capturing just one pixel of a full image…

Compound eyes also have an almost infinite depth of field—that is, objects stay in focus regardless of how far they are from the eye. So, flies can clearly see something far and near objects at the same time, without having to adjust any lenses. And compound eyes are also exquisitely sensitive to movement, since their owners can compare the passage of shapes across different ommatidia.

Wide angles. Sharp focus at all distances. Sensitivity to movement. If you were building a surveillance camera, these are exactly the properties you’d want. Indeed, Rogers thinks that surveillance is an obvious application for his fly-eye design.”

Now Incest App Video Demo

Living has become complex and so isolated (though the world has shrunk on the Internet) and sex between strangers have become a common and easy  that one might even bump into his close relatives..

Iceland faced this problem and recognized this as a Problem.

A Mobile Application has been developed to avoid bedding close relatives,unwittingly.

( you can do nothing about those who do so wittingly!)

The Story and Video Demo.

Avoiding incest in Iceland just got easier. A new app determines if hookups on the close-knit island nation are sharing too many roots in the family tree, News Of Iceland reports.

The “Islendingabók” (“Book of Icelanders”) app allows amorous users to tap into a bloodline registry that judges whether romance is advisable.

The app’s slogan, “bump the app before you bump in bed,” invites would-be couples to bump their smartphones together for a verdict to prevent problems later…

The database, which draws from 1,200 years of genealogical info, has been around since 1997, according to the New York Daily News. Before the app was developed, couples in Iceland had to search the database by typing in their names and Icelandic ID numbers. In the heat of the moment, that might be difficult.

Now, all it takes is a phone kiss.

As previously reported, the possibility of romancing a too-close relative is relatively high in Iceland, given that the island has around 300,000 mostly native residents.

According to GlobalPost, a little verbal investigation also helps to avoid inbreeding. “Hverra manna ert þú?” (“Who are your people?”) is a common question exchanged..

Now a group of University of Iceland in Reykjavík students have taken it a step further and created an Android app to help end cousins from dating. NBC News reports:

When you tap phones with someone who has the app, it brings up an alert if the owners of the two phones share a grandparent. (Of course, if you don’t already know who you share a grandparent with, incest may be the least of your problems, but the team says it is looking into functionality for spotting common great grandparents, too.)

The app, called Sifjaspellsspillir translates to “Incest Destroyer.”

An iPhone counterpart is currently in production.

Emergency Charge Mobile, Cell Phone Details

Some useful tips to charge and preserve the Mobile Phone charge,

Charging a Cell Phone.

Increase Time between Charges

1. 1

   Turn the phone off. This will probably be the most effective and simple way of conserving your battery’s power. Why? This will help conserve energy and also charge your phone. If you don’t plan on answering the phone while you’re sleeping or after business hours, just turn it off. Do the same if you are in an area with no reception (such as a subway or remote area, since constantly searching for service depletes the battery fairly quickly.) Some phones have an automatic power save feature, but it takes about 30 minutes with no service to kick in. By then, much battery power has been used. If you don’t need to receive or make calls but are using a smartphone as a PDA, disable the phone functionality (flight mode).

2. Stop searching for a signal. When you are in an area with poor or no signal, your phone will constantly look for a better connection, and will use up all your power doing so. This is easily understood if you have ever forgotten to turn off your phone on a flight. The best way to ensure longer battery life is to make sure you have a great signal where you use your phone. If you don’t have a perfect signal, get a cell phone repeater which will amplify the signal to provide near perfect reception anywhere.
3. Follow the method of full charge and full discharge. Don’t put your phone on charging when there is the battery remaining it for another few hours unless it’s very important. Charge it when your battery is about to get totally discharged and when you put it for charging, let it get charged totally. OR Do the opposite – Some Articles [1] indicate that with Lithium batteries, doing shallow discharges and frequent charging prolongs battery life.
4. Switch the vibrate function off on your phone, using just the ring tone. The vibrate function uses additional battery power. Keep the ring tone volume as low as possible.
5. Turn off your phone’s back light. The back light is what makes the phone easier to read in bright light or outside. However, the light also uses battery power. If you can get by without it, your battery will last longer. If you have to use the back light, many phones will let you set the amount of time to leave the back light on. Shorten that amount of time. Usually, one or two seconds will be sufficient. Some phones have an ambient light sensor, which can turn off the back light in bright conditions and enable it in darker ones.
6. Avoid using unnecessary features. If you know it will be a while before your phone’s next charge, don’t use the camera or connect to the Internet. Flash photography can drain your battery especially quickly.
7. Keep calls short. This is obvious, but how many times have you heard someone on their mobile phone say, “I think my battery’s dying,” and then continue their conversation for several minutes? Sometimes, the dying battery is just an excuse to get off the phone (and a good one, at that), but if you really need to conserve the battery, limit your talk time.
8. Turn off Bluetooth. It will drain your battery very quickly.
9. Same goes for WIFI, GPS, and infrared capabilities, if your phone has these features built in. Keep them off except when you need them.
10. Turn the brightness of the display to the lowest setting possible.
11. Use GSM rather than 3G – Using your phone in 3G / Dual Mode will drain the battery quicker than if you just use GSM mode – have a look at your phones spec and you’ll see it will quote two different battery life times – normally 50% more for pure GSM use.

Save  a wet Cell Phone.

Wet Cell Phone

Take the phone out of the water as soon as possible. Ports for hands free kit, tiny hole for microphone, charging, usb cable connectivity and the plastic covers on cell phones even though tight can freely allow water to enter the phone in a just a few seconds of time. Grab your phone quickly, and turn it off immediately, as leaving it on can cause it to short circuit – if it has been in water, assume it is waterlogged whether it is still working or not.(wiki How)

 

Nokia Ringtone Has Morse Code

Nokia phones are nearly indestructible, which is an amazing feat on it’s own considering iPhones seem to break if you drop them onto a pillow. Anyway, Nokia not only creates indestructible phones, but they also create their ringtones in clever ways!

Nokia Lumia 920

For example, the ‘Ascending’ ringtone is actually Morse code for ‘Connecting People’, which is Nokia’s slogan. Similarly, the ‘Standard’ ringtone is Morse code for ‘M’ – which stands for message. It’s nice to see phone developers getting a little bit original with their design.

Side note – In Asia, the digit 4 never appears on a Nokia handset model number. Why? Because ‘4’ is considered an unlucky number in many parts of Southeast/East Asia. To learn even more odd facts about Nokia, you should click the source!
