Raspberry Pi Ten Little Known Functions

Raspberry Pi is a pocket computer that appears in several versions. These models can be used in a plethora of interesting projects, which apply board hardware to drones, retro gaming consoles and devices that leave your smart TV. In addition, you can also create a small server to free access from PCs from the network to the printer or even a kind of cloud storage itself.

Here are ten examples of projects using some version of Raspberry Pi and know which ones are most interesting to you. It is worth mentioning that creations have varying degrees of difficulty, and may require the purchase of materials other than plaque.

Print server Raspberry Pi

Raspberry Pi can turn a central switch on so that your printer is accessible to all users within the home network. To do this, simply install a Linux distribution on the card and set up a print server.

With everything working, just leave your card and printer connected, being careful to ensure that Raspberry Pi is connected to your network. Then scan the devices using a device’s operating system and send documents directly to the printer.

Media center Raspberry Pi

The various versions of Raspberry Pi offer low cost hardware, but still capable of playing full HD video. Featuring HDMI port, the card also allows connection with a TV.

It is the sum of these two characteristics that gives the user the possibility of transforming the device into a media center. There are dedicated operating systems to the task, bringing in embedded video and music players, as well as a number of media sharing and organizing features. Thus, Raspberry Pi can be a Cheap alternative to any TV Box with Android TV, for example.

Digital radio Raspberry Pi

Another simple and friendly project for beginners is to create a digital radio with Raspberry Pi, since it is possible to create an FM tuner with the right components. It is worth mentioning that having a pirate FM transmitter in Brazil is a crime, and it is only allowed to have the tuner in hand, as a common fast.

In the uniquely digital model, it is possible to use software for Linux capable of searching the stream of a radio that offers its programming via Internet. More evolved projects also include lists with several broadcasters, LCD screen to control the radio, buttons and even cases.

Old games console on Raspberry Pi

Inexpensive and able to handle games from most generations of consoles and old PCs, Raspberry Pi can become a good retro gaming platform. There is even an organized developer community that produces packages with emulators and graphical quality interfaces for the mini PC.

With support for Bluetooth connections, the Raspberry Pi can be paired with wireless controls, which can help in connecting newer models. More elaborate projects put the board in the center of a home-made arcade or portable console, taking advantage of the shell of an old PSP or even a 3D printing template.

Your own cloud Raspberry Pi

Buying a NAS – set of external HDDs connected to the Internet to access from anywhere – may not be very interesting to anyone who just needs storage connected to the Internet. Raspberry Pi can be used as a control platform for HDDs using the four USB ports on the card.

By connecting the mini PC to the network and configuring services like ownCloud, you get access to your files from anywhere. That way, it is not necessary to invest in an account in services like Google Drive, Dropbox, among others.

Web Server Raspberry Pi

Another Internet application that you can test is the web server. In this way, Raspberry Pi behaves like a machine connected to the network and can host a website, blog or even some network functionality and an e-mail server, for example. The big question is that too simple hardware makes the badge unfeasible for any more ambitious use.

Therefore, a website that may end up having thousands of hits at the same time will end up catching on the board. Nonetheless, Raspberry’s simple hardware is accessible and allows the development of prototypes for testing, and should handle the problem of less demanding projects such as a blog, for example.

Drones

Another interesting project, and also more challenging, is to use Raspberry Pi as the brain of a drone, both flying models and more conventional robots. Just like other examples in this list, there are plenty of internet tutorials explaining what you need to do to build yours.

There are kits with the parts that you will need, usually formed by motors, wheels or propellers and a computational module to command this, always compatible with both Arduino and Raspberry. Depending on the profile of the robot or drone, you can use an app to control, create standalone routines, or even use video game controls to pilot your creation.

Tablet

Among the plethora of accessories and add-ons available for Raspberry, there are some touch screen options. They can be attached to the board which, with the aid of a battery, can turn a tablet. It is also possible to use modules for SIM cards and use the mini PC as a kind of smartphone.

Despite this, the project has some limitations, especially in the adaptations of Android to the versions of Raspberry Pi. Also, do not expect the slim design of an iPad: the end result is not so portable and compact, even using 3D printed cases available on the Internet.

Security camera

If a drone or tablet looks too complex, a Raspberry-controlled security camera may be a more affordable application for beginners. In general, the various examples available on the Internet require only a Raspberry Pi 3, a USB webcam and some storage media, such as a thumb drive.

There are also models with motion sensors that trigger the camera automatically, recording the capture on a pendrive. Otherwise, you can schedule times for the camera to turn on by itself, or leave it on all the time – instead of a thumb drive, better use a hard drive.

Projector

Slightly more complex, this project requires you to invest in an add-on available on the Internet to convert the Raspberry signal for projection into an 854 x 480-pixel, below-HD resolution image. Using a battery and Raspberry Pi Zero you can even develop something that, fit in the pocket, is completely portable and at a cost far below the one practiced in portable projectors for sale in the market.
