Beginner’s Guide: Setting Up Raspberry Pi for the First Time

 

As you may have already known, there are 2 different models of Raspberry Pi: the Model A and Model B. Model A is cheaper since it has no Ethernet, has lower memory capacity of 256MB, and contains only one USB connector. Model B, on the other hand, has Ethernet, has 2 times the memory, and boasts 2 USB ports. While you may think that Model B is just an enhanced version of the A, the truth is, it is not. As a matter of fact, B came first than A. Also, A was made to give Raspberry Pi users a lighter and cheaper version of computer that they can easily toy with.

But whichever model you choose from your preferred Raspberry Pi seller in Australia, you will need to get a few setup tips to help you get started. To ensure you are doing things the right way, we have compiled some tips for you.

How to Set Up Raspberry Pi

While most of us expect that Raspberry Pi can run right out of the box, it is imperative to know that it can’t. Instead, you will need to purchase the following peripherals first:

  • Case. There is no official case for the Raspberry Pi yet, but there are bunches of resellers out there that offer Raspberry Pi along with a colorful case. There were rumors that the minicomputer does fit in the Altoids tin can, but actually, it does not.
  • Power supply. Upon purchase, the Raspberry Pi package does not come with one so you will have to get a USB compatible cable to get it plugged into the wall socket.
  • RCA or HDMI cable. You cannot tweak and install anything in your minicomputer without a visual display. The great thing about this computer is that you can easily connect it to a computer monitor by means of an HDMI cable, or simply plug it in your analog TV using RCA connector.
  • USB keyboard and mouse. To have better control with the Raspberry Pi, you will need to purchase these. Just about any wired or wireless types will do; thanks to the versatility of this handy device.
  • SD card. To start, you will need to use a 4GB memory card. However, you may also do away with as big as 32GB.
  • Another computer unit. Unfortunately, you can’t get the Pi running without a standard desktop PC or laptop.
  • SD card reader. While Raspberry Pi can work with this, you will need to use on your computer unit when transferring software to your Pi. Some computers have this; but if yours doesn’t, you will have to invest in one.

Instructions

Now that you have all of the components on hand, here are the next important steps that you must follow:

  1. House your Raspberry Pi in a case. Obviously, this is the first thing you want to accomplish, unless your Pi is already built with a case upon purchase.
  2. Set the Pi aside and use your computer. Attach the memory card to your PC and have it formatted according to manufacturer instructions. During the process, a recovery program will also be installed so your files are secured even if the SD card breaks.
  3. Download NOOBs on your computer. NOOBS (New Out of Box Software) is a beginner’s software that contains installation components for Linux and other applications related to it.
  4. Transfer NOOBS to the SD card. This is also an important step, unless you already specified your SD card as default download path.
  5. Place the SD card into the Pi. The port for the SD card can be found on the Pi’s underside. While doing so, make sure that the card is oriented properly so the minicomputer can read it accordingly.
  6. Connect other components. These include the power supply, the HDMI or RCA cable, mouse and keyboard.
  7. Turn it on. Once powered on, Raspberry Pi will show you the NOOBS screen.
  8. Choose your OS. By default, Raspberry Pi’s operating system is Raspbian. For beginners, this is the best OS to tinker with.
  9. Allow the file to copy. Once finished, you’ll get the message, “Image applied successfully”. When you see this, choose the return option and Pi will reboot. After this, you should see it displaying a graphical user interface, which is very similar to that of Windows 98.
  10. Use your Raspberry Pi. You’ve just successfully set up your Pi. Now, you can use any way you want, just like how you would in an ordinary PC.

From this detailed guide on starting out with Raspberry Pi, you should be on your way to enjoying the utmost flexibility of this small-but-terrible PC. Grab your own today (if you still don’t have one) to boost your computer skills or simply make your techie cravings happen the easy way.

What A Postman Can Do To Protect Themselves From Dogs

 

The postman-dog war has become pretty famous due to cartoons and movies, but it is every bit as real as shown in the media. Why do dogs have an aggressive behavior towards postmen?

By nature, a dog is the protector of his territory. It considers the place it is living at as its territory and it wants to protect it from strange people coming to the house with a package.

Postmen have the option to use an electronic dog repeller to drive the dog away so that they can complete their duties without worrying about a dog attack or even a bark. The electronic dog repeller emits a sound at high-frequency, which can only be heard by dogs and some other animals. The sound confuses the dog and sends it away so that the postman can do their work.

Postmen can also carry pepper spray with them. Pepper spray, like an electronic dog repeller, can confuse and distract the dog by releasing a cloud of gas. It’s effective for up to 20 minutes, giving the postman ample time to deliver the mail and go away.

However, most postal workers have found that pepper spray is difficult to use when they are being attacked by a dog. This is why a new device has been given to them, which makes a hissing sound and releases compressed air to scare away dogs. This device works faster than a pepper spray so that it can effectively scare a dog away.

The postal workers are also given special instructions on what to do when confronted by a loose dog. They are specifically told not to enter premises with a loose dog because even the friendliest dog could consider them a threat. If a situation arises where they are confronted by the dog, they should position their bag between the dog and themselves as a protection. They should never turn and run as this could prompt the dog to chase them. Instead, they should slowly back away.

Controlling a Raspberry Pi wirelessly

raspberry-pi-dongle

Raspberry pi is a single board computer designed by raspberry pi foundation. It was made specifically to help the people and children in far flung areas to bet the basic computer education and help them to attain the knowledge about the advanced ways of the 21st century at the fraction of the cost of a bigger personal computer or a laptop. Raspberry pi offers everything that is in a computer at cheaper rates and the technology used in this computer is also world class. The foundation is from United Kingdom and operates from there. The first batches of boards for the raspberry pi were made in the Taiwan as it is known to be a good producer of computer hardware related items. The user is given a lot of options in this computer, like controlling a raspberry pi wirelessly amongst others. So it can be remotely controlled to use it. But how can we actually control it through a wireless connection. This is a little tricky, as it is not like your everyday system so the method of controlling is also not orthodox. Let us go through the major steps involved in controlling a raspberry pi wirelessly.

The raspberry pi can be controlled wirelessly by even a mobile phone. We can adjust the pi to a mobile phone interface when a monitor or LCD screen is not around or you do not have a keyboard to work with. There are very good software available in the market for this purpose and all of them has a simple purpose, and simple steps to get you phone to work as a screen for the pi. It can be used to control many things by setting us a connection, like electric windows or even lighting of the house.

Another crucial thing is setting up a wireless connection on the raspberry pi, it is necessary while controlling a raspberry pi wirelessly. It can be done in some simple steps. First you wil need a USB wireless adapter which is easily available in the market, buy it and then plug it into the slot for the USB on the pi. After doing that only the configuration has to be done and voila, you are connected to a wireless connection in no time.

First of all simply login to the raspberry pi using a keyboard or any other input device you are using, the login can be done in two ways, by using the prompt screen or by using the remotely accessible VNC viewer. After logging in, go to the start screen and press the wireless configuration sign. A prompt window will then show up on the screen and show some buttons, simply click on the “scan” button on the window and the computer will scan all the wireless connections in the area. After that a list will appear and you can choose the required wireless network by clicking on it and selecting it. Now that we are connected to the network we can ping google to inspect our network or we can enter the command “sudo /sbin/ifconfig “into a terminal. This is how one can set up a wireless connection on pi and control it wirelessly.
