Raspberry Pi as a Computer

Raspberry Pi is an amazing devise in credit card size that can replace even CPU of your computer hence you can use Raspberry Pi as a personal computer!!! The Raspbian OS comes with Web browser, pdf viewer, Python games etc. You can download necessary application softwares from Raspberry Pi store. You can connect connect display, mouse, keyboard etc. with your Raspberry Pi. In the figure shown below showing connecting USB keyboard to your Raspberry Pi. Inserting the USB Keyboard Connecting a display The Raspberry Pi can be connected by HDMI or composite video directly. With the use of an adapter you can connect it by DVI or VGA. You should use HDMI or DVI whenever possible because they give a better picture. Look at the sockets on your display to determine how to connect your Raspberry Pi. Connecting via HDMI If your display has an HDMI input, as shown below, then connect your Pi with an HDMI-HDMI cable. This is the only type of video connection that can also be used...

Power up Raspberry Pi

We discussed how to flash OS on SD card from different operating system like Windows, Linux or Ubuntu and MAC. Now we want to insert SD card on Raspberry Pi and give proper power supply for Raspberry Pi. This is discussed in this session. Inserting SD card on Raspberry Pi One of the most frequently neglected parts of a system tends to be the power supply—at least when everything is working. Only when things get weird does the power supply begin to get some scrutiny. The Raspberry Pi owner needs to give the power supply extra respect. Unlike many AVR class boards, where the raw input voltage is followed by an onboard 5 V regulator, the Pi expects its power to be regulated at the input. The Pi does include onboard regulators, but these regulate to lower voltages (3.3 V and lower). Figure shown below  illustrates the rather fragile Micro-USB power input connector. There is a large round capacitor directly behind the connector that people often grab for leverage. It is a mis...

When want to go for RasPi?

Who Should Use the RasPi Anybody who wants to transform an engineering concept into a real interactive electronics project, prototype, or work of art should consider using the RasPi. That said, integrating high-level software and low-level electronics is not an easy task. However, the diffi culty involved in an implementation depends on the level of sophistication that the project demands. The RasPi community is working hard to ensure that the platform is accessible by everyone who is interested in integrating it into their projects, whether they are students, makers, artists, or hobbyists. For example, the availability of the Scratch visual programming tool on the RasPi (tiny.cc/erpi101) is an excellent way to engage children with both computer programming and the RasPi. For more advanced users with electronics or computing knowledge, the RasPi platform enables additional development and customization to meet specific project needs. Again, such customization is not trivial:...

More about Installing Raspbian

Now that you know a bit more about Raspbian, it is time to get started. The first thing that you need to do is plug in your Raspberry Pi and then install Raspbian onto an SD card. This process is different from installing software onto your Windows PC or Mac. In this post, we will cover the following topics: • SD card specifications • Downloading Raspbian • Imaging Raspbian onto your SD card SD card specifications It is recommended that your SD card has the following specifications: Capacity: At least 8 GB Class       : Class 4 is minimum but class 10 is recommended Make sure that you get the correct SD card. Raspberry Pi A and Raspberry Pi B both use a full-sized SD card. Raspberry Pi B+ uses a mini SD card. It is highly recommended that you don't run your Raspberry Pi without an SD card. This is because all the hardware on your Raspberry Pi will not be set up correctly. This might lead to the damage of your Raspberry Pi hardware. Down...

Raspberry Pi Operating System

Raspbian No matter how good the hardware of the Raspberry Pi is, without an operating system it is just a piece of silicon, PCB, and a few other materials. There are several different operating systems for the Raspberry Pi, including RISC OS, Pidora, Arch Linux, and Raspbian. Currently, Raspbian is the most popular Linux-based operating system for the Raspberry Pi. Raspbian is an open source operating system based on Debian, which has been modified specifically for the Raspberry Pi (thus the name Raspbian). Raspbian includes customizations that are designed to make the Raspberry Pi easier to use and includes many different software packages out of the box. Raspbian is designed to be easy to use and is the recommended operating system for beginners to start off with their Raspberry Pi. Debian The Debian operating system was created in August 1993 by Ian Murdock and is one of the original distributions of Linux. As Raspbian is based on the Debian operating system, ...

Raspberry Pi

Despite first impressions, the Raspberry Pi is not a tasty snack. The Raspberry Pi is a small, powerful, and inexpensive single board computer developed over several years by the Raspberry Pi Foundation. If you are a looking for a low cost, small, easy-to-use computer for your next project, or are interested in learning how computers work, then the Raspberry Pi is for you. Raspberry Pi 3 Model B The Raspberry Pi was designed as an educational device and was inspired by the success of the BBC Micro for teaching computer programming to a generation. The Raspberry Pi Foundation set out to do the same in today's world, where you don't need to know how to write software to use a computer. At the time of printing, the Raspberry Pi Foundation had shipped over 2.5 million units, and it is safe to say that they have exceeded their expectations! The Raspberry Pi Foundation The Raspberry Pi Foundation is a not-for-profit charity and was founded in 2006 by Eben Upton, Rob Mul...
