"With so many Raspberry Pi projects to choose from, it can be tricky to find the one you really want to build. Our advice is to find a way to marry the Pi with something you really love. One great example is TV and movie robots - iconic characters from popular sci-fi that can be rebuild at home with a Raspberry Pi built in. Once constructed, your robot might be able to utter commands when a condition is met (perhaps a sensor detects motion). Or it might move around, learning about its surroundings, or reading information to you from Wikipedia. Whatever you have in mind, it should be relatively straightforward to plan and execute. It may take some time, however. Here are five example projects that show how you can combine a Raspberry Pi 2 or later with your favorite fictional robot. 5 Things Only a Raspberry Pi 2 Can Do 5 Things Only a Raspberry Pi 2 Can Do The latest edition of the pint-sized computer is awesome. So awesome, in fact, that there's 5 things you can only do on a Raspberry Pi 2. READ MORE 1. R2-D2 We've all wanted our very own astromech droid, haven't we? Sure, no one on earth is (currently) operating a light speed drive, but Star Wars droid R2-D2 has far greater abilities than onboard spacecraft maintenance. For instance, he can hold torches, carry a tray of drinks, and launch lightsabers across pits in the desert. Okay, it's unlikely you'll manage to get your own R2-D2 robot to do that… but don't let that put you off. Check out this little guy, controlled by a Raspberry Pi. While this project was based on an existing R2-D2 toy, that shouldn't limit your ambition. You'll find plenty of R2-D2 builds on YouTube. There's a massive R2-D2 building community online. Finding one that has a drive unit should be ideal for integrating a Raspberry Pi (and perhaps an Arduino, which you can use the two together) and developing a more realistic R2-D2 experience. Arduino vs Raspberry Pi: Which Is The Mini Computer For You? Arduino vs Rasp

"Have you ever been on the road and wish you could scan a document? Or in a meeting and needed to share a hard copy document? However, your scanner was back in your office… Today, I want to show you an easy solution."

Motorola LS3408 - The Symbol LS3408FZ handheld scanner offers superior performance, reliability and user-friendly ergonomics to improve productivity. Offers NEW, NEW SURPLUS and REFURBISHED Symbol products and REPAIR SERVICES.

"Your smartphone camera is one the ultimate lifehack tools. We've already taken a look at four ways you can be making better use of your smartphone camera to turn your smartphone into a makeshift scanner, a memory aid, and more, and today we're at it again. With the help of a few cool apps, your camera can also turn your phone into a film scanner, a font or color identifier, the ultimate search tool and more."

"Here are 10 QR readers for your iPad - all bar one for Free. QR Code scanners can be lots of fun in the classroom. We have used them to generate discussion around types of data, presented classroom information as well as presenting clues to treasure hunts. The treasure hunt idea is always a popular way to finish a unit of work. We normally use QR codes to give hints to the next clue or to the location of the clues. The students have to use the information from the unit of work to solve the clues along the way. Lots of fun, lots of laughs and lots of learning. "

"You either love them or hate them. Some educators feel like using QR codes are unnecessary; why not just give kids a shortened URL? Last year, I asked my high school students what they thought about QR codes as a way to access information in my Library Learning Commons. Responses varied slightly, but the general consensus was: "Nah. We don't use them." "They're lame, Sorry Miss." Then came the iOS 11 update about a month ago. This update turned the iphone camera into a QR code scanner."

"It's no secret among my friends and family that I have an Evernote addiction. Between Evernote and my personal scanner, I cannot decide which one is more important to my work and personal life. I started out with the free version of Evernote, but quickly figured out that the Premium version was the only way to go based on the quantity of documents I store as well as the number of times I must access stuff offline. Suffice to say, if you're not using Evernote, I highly suggest giving it a try - only then will you be able to truly determine if it's a beneficial service or something you can do without."

"If you want to do some 3D scanning, you usually have to get either a dedicated scanner or a less-than-elegant add-on. Microsoft Research and the University of Oxford think there's a better way, though. Their MobileFusion project captures 3D models using only an app on your smartphone. The software scans objects by comparing image frames from your phone's camera and creating stereo depth maps from the results -- you just have to walk around an object to get more detail. It's much like Kinect Fusion, but you're not tied to either a PC or a clunky peripheral."

"The Lock screen exists in between states, when your iPhone or iPad is no longer asleep, but is also not yet open and fully functional. It can protect your device from unauthorized access and actions by a simple slide-to-unlock gesture, by a 4 number pin-code, by a strong alpha-numeric password, or Apple's Touch ID fingerprint identity scanner. Yet the Lock screen can be functional as well. If you want to, you can access Notification Center and Control Center, the Camera, and Siri. On the iPhone, you can even make emergency calls. Yes, the Lock screen can be secure or it can be convenient, it's entirely up to you!"

"Microsoft today launched Office Lens, a mobile document scanner app that works with OneNote, for iOS and Android smartphones. The app, which allows users to snap photos of paper documents, receipts, business cards, menus, whiteboards, sticky notes and more, was first launched a year ago as an application designed only for Windows Phone devices."

Sometimes being unaware of the USB virus-or malware-infection, you may put your computer security at stake. The AutoPlay feature of the Windows, executes the file or program stored on your device, without asking for permission, and that may bring havoc on the operating system as well as the confidential data stored on the machine. Thus, you need to disable the AutoPlay feature to deter such security breaching.

Now, Mac is the next target of hackers. Till now, Mac operating system was untouched by hackers and Mac users were accessing web freely.
