If you dont already have these wall sockets, you can have an electrician replace one of your regular wall sockets with USB A port sockets or you can use adapters. More Expensive Power Supply Options If you do not want to share a charger with your phone or ebook reader, you can buy your Raspberry Pi its own power peripherals. The power plug will allow you to plug into any wall socket for power.

If you plan on sticking the Raspberry Pi in a backpack or case for travel, consider getting a USB power plug that has the ability to fold up its power prongs. This will make the power plug into a nice small cube that is compact and easy to carry. Even better is a power cord that has both an AC power plug on one end and a USB micro B male connector on the other end. You can typically find highly rated power supply cords in this category that provide better power stability for your Raspberry Pi projects.

Output Display For a very small device, the Raspberry Pi has the ability to display incredible images. The Raspberry Pi also provides composite output, allowing you the flexibility of using older equipment for output display.

Once again, you get a choice of what you use to get your Raspberry Pi functional. Working with Older Display Equipment If you have access to an old analog television, you possibly can display your Raspberry Pis output to it.

The three RCA connectors are typically color-coded yellow video , white, and red stereo audio. They are typically colored yellow, white, and red to match the composite cables three color-coded RCA connectors.

Be sure you read any buyer reviews on such a converter before purchasing onemany do not work with a Raspberry Pi. Also, you might have to make some configuration file changes to get such a converter to work with your Pis HDMI output. You also can hook up a computer monitor with a DVI port on it. Also, like a composite video cable, DVI does not carry an audio signal. Thus, if you also need sound, you might need a converter that will split the HDMIs video and audio signal output and enable you to hook up a separate audio cable to speakers.

Working with Up-to-Date Display Equipment Using up-to-date display equipment is the easiest and best way to capture a Raspberry Pis video and audio output. Of course, you should be sure you purchase an HDMI cable that is long enough to accommodate your needs. The easiest decision you will have to make about Raspberry Pi peripherals is which keyboard and mouse to use.

To type in your Python programs, try various Python commands, and click Pis graphical user interface GUI icons, you need a keyboard and a mouse. Check their power ratings and determine whether your selected power supply can support them.

Depending on how your local network is configured, connecting to the network can be as simple as plugging an Ethernet patch cable into the Raspberry Pis network port and into the back of your router.

In this case, all you need to purchase is an Ethernet patch cable with two RJ45 connectors. With a wired connection, you have increased network transmission speed and typically fewer network connection issues.

You also can set up your Raspberry Pi to connect via a wireless network. In this case, you need a USB wireless network adapter, which often comes with the prepackaged Raspberry Pi kits. The downside of this method is that you need to use one of your Pis USB ports. But with a wireless setup, you have much more flexibility.

Nice Additional Peripherals Now that you know which peripherals you absolutely must have to run your Raspberry Pi, you can think about a few additional peripherals that will make your life with the Raspberry Pi easier.

You dont have to have a case to protect your Pi, but having one is a good idea. Cases for the Raspberry Pi come in various shapes, sizes, and colors. The case has openings on the side that allow access to the various ports. Learn more details about this case at raspberrypi. Many Raspberry Pi enthusiasts like using a clear case to protect the Pis circuit board but allow it to be proudly displayed.

Other Raspberry Pi owners need a more polished appearance for their Pi. You need to decide which kind of case meets your needs. You easily can switch your Raspberry Pi to a different case if you change your mind later! A small spark from your hand on the exposed circuit board could permanently damage your Raspberry Pi. This is a good reason for keeping your Pi in a case. Portable Power Supply A portable power charger is wonderful, basically giving your Raspberry Pi power wherever it goes.

A portable power charger typically contains a lithium-ion battery and can be charged via either a wall socket at home or a USB cable connected to a computer. You can charge your portable power charger and carry it with you to power your Raspberry Pi when other power is not available. To be able to power a Raspberry Pi, a portable power charger must be able to provide the necessary 5 volts and mAmA or above depending on your power needs.

More expensive portable power chargers can be powered by multiple sources, such as your cars volt power port as well as wall sockets.

You will still need to purchase a cable that has a USB A male connector on one end and a USB micro B male connector on the other end to connect the Pi to the portable power charger. The nice thing about this is that you can charge your portable power at the same time you are powering your Raspberry Pi at home. Just dont forget to unplug your portable power charger when you remove or insert peripherals on your Pi! No worries. Just purchase a self-powered USB hub, which gets its power by being plugged into an electrical outlet.

A bus-powered USB hub draws the power it needs from the computer to which it is connected. Therefore, it would try to draw power from your Raspberry Pi. Typically, a self-powered USB hub can supply up to mA to each device connected to it.

Deciding How to Purchase Peripherals Now that you have seen what the Raspberry Pi needs in the way of peripherals, you can decide which ones will be best for you. You can either buy the Raspberry Pi with its necessary peripherals in a prepackaged kit or purchase the Raspberry Pi and its necessary peripherals separately.

If you decide to purchase a prepackaged kit, keep in mind the following points: You will spend more money on this option than if you buy the Raspberry Pi and peripherals separately. Kits vary, so be sure to buy a kit that has the peripherals you want or be prepared to buy any that dont come with the kit.

Typically, the kits do not include a USB mouse and keyboard. Many kits have the necessary software to install an operating system preloaded on the microSD card. If you get such a kit, you can skip downloading the software and loading it onto your card section of this hour. Getting Your Raspberry Pi Working After you have made your purchase decisions and received your Raspberry Pi and its necessary peripherals, you can begin to really have some fun.


The first time your Raspberry Pi boots up and you realize what a powerful little machine you now own, youll really be amazed. The following sections describe what you need to do to prepare your Pi for booting.

Doing Your Research As with many other things in life, if you plan ahead and do your research, getting your Raspberry Pi up and running should go smoothly and quickly. This up-front time and effort are very worthwhile. And many excellent resources can help. Books like this one help you get your Raspberry Pi working and troubleshoot problems.

Also, there are many sources on the Internet that can assist you in your Raspberry Pi research. One of the best comes from the Raspberry Pi Foundation. It maintains a website raspberrypi. At this site, you can also find software downloads and the latest news concerning the Raspberry Pi Foundation and the Pi itself.

You should start your Raspberry Pi investigation at this resource. Exploring the Installation Software After you have completed your initial research, the next step is to download the installation software. The Raspberry Pi Foundations website, raspberrypi. Did You Know? If this is the case, you can skip ahead to the section Plugging In the Peripherals.

If you have different computers, such as a Windows machine and a Linux machine, available to you, choose the machine you feel the most comfortable using.

This appendix will take you step-by-step through process and provides a more in-depth explanation than given here. The Network install only option is typically faster to download because it does not contain any preselected operating systems; however, you must have your Pi connected to the Internet for this installation to work properly.

Both versions do allow you to pick which operating system to install on your microSD card. Otherwise, your Pi must have Internet access. This will verify that no file corruption occurred while the file was being downloaded. Windows, OS X, and Linux each handle producing a checksum differently. Check Appendix A if you need additional help with verifying the checksum. A checksum is a string of numbers and letters created by a particular mathematical algorithm.

Running a files data through a checksum algorithm produces a unique checksum. If any of the files data changes, the checksum changes. Checksums can therefore be used to ensure a files data has not been changed or corrupted. This is handy for checking downloaded files. If the checksum of the downloaded NOOBs Zip file does not match the original files checksum on the website, download the file again.

When the checksums do not match, it typically means the file was corrupted as it was downloaded. Are you really serious about your post… or was this a joke Everyday Scripting with Ruby: For Teams, Testers, and You brookendsolutions. Although commonly thought of as simple subtyping mechanism, there are actually many different uses of inheritance. Ruby is a dynamic, open source programming language with a focus on simplicity and productivity.

It has an elegant syntax that is natural to read and easy to write. Every bit of information and code can be given their own properties and actions. Object-oriented programming calls properties by the name instance variables and actions are known as methods , e. Want to kickstart your project in record time, or prototype a new idea for your next big web app?

Ruby and Ruby on Rails can get you there quickly. Programmers often use tools that translate slower languages like Ruby and Python into faster languages like Java or C.

But that faster code must also be translated — or compiled, in programmer lingo — into code that the machine can understand. That adds more complexity and room for error pdf. If it is, we jump to line 0, which tells Spaghetti that we want to exit, if you remember online.

For example, we might want to add instance variables to our BankAccount class: Now we have two instance variables called accountNumber and accountName with associated accessor methods , cited: Ruby on Rails 3.
