Let’s start with the simplest use for a Raspberry Pi: a desktop computer. This makes sense in several ways, not least because this project ensures you have almost all of the equipment you’ll need for your Raspberry Pi.

Along with the Pi itself, the microSD card, and power supply, you’ll need a HDMI cable and a suitable display. As with a traditional computer, you’ll also need a USB keyboard and mouse.

The Raspberry Pi 3 has built in Wi-Fi and Bluetooth, but if you’re using a different model, you’ll need compatible USB dongles (you can check compatibility at elinux.org’s Raspberry Pi Hub). If you prefer to use Ethernet, however, the Pi is equipped with an Ethernet port.

Once you’re set up, and have your preferred operating system installed (unless specified, all of these projects require the latest version of Raspbian How to Update Your Raspberry Pi to the Latest Raspbian OS How to Update Your Raspberry Pi to the Latest Raspbian OS Here's why Raspbian Stretch is the best Raspberry Pi update in a while, and how to update your own Raspberry Pi to it. Read More ), you’ll find all of the tools you need to run your Raspberry Pi like a desktop computer.

LibreOffice is pre-installed, along with the Chromium browser.

2. Wireless Print Server Make Your Own Wireless Printer With A Raspberry Pi Make Your Own Wireless Printer With A Raspberry Pi Fewer cables, flexibility about where you can put your printer – wireless printing is a win-win. Unless you have an older printer. Raspberry Pi to the rescue! Read More

awesome uses for a raspberry pi

If you have an old printer that you really like using, but which cannot be connected to wirelessly, you’re probably inclined to dispose of it safely. But you really don’t need to. All you need is a Raspberry Pi connected to your home network, and some print server software.

This is done by installing the Samba file sharing software, followed by CUPS. The Common Unix Printing System provides drivers for your printer, and provides an administration console.

Once this is set up, configure the Pi to ensure any Windows or macOS computers on your home network can access the printer. That’s all there is to it. Note that this really depends on your printer having a USB cable. If it doesn’t, adaptors are available… but if your printer is that old, it should probably be upgraded to something that is cheaper to run.

3. Add AirPrint Support to Your Pi Print Server Add AirPrint Support To Your Raspberry Pi Print Server Add AirPrint Support To Your Raspberry Pi Print Server Do you want to be able to print from your smartphone or tablet to your old-fashioned, non-wireless printer? With a Raspberry Pi, you can. Read More

The above project only takes things so far. It’s ideal for printing from a Windows, Mac or Linux computer, but what about tablets and phones? For that, you’ll need Air Print support, which can be added via a single script.

Although printing is available natively on iOS devices, Android tablets and phones will require a dedicated app. Most new printers offer support for printing from mobile devices. With a Raspberry Pi, you can extend this functionality to older printers!

4. Media Center Install Kodi to Turn Your Raspberry Pi Into a Home Media Center Install Kodi to Turn Your Raspberry Pi Into a Home Media Center If you have a Raspberry Pi, you can turn it into a cheap but effective home media center just by installing Kodi. Read More

While there are no figures, there’s a very strong possibility that the main use for a Raspberry Pi is as a Kodi media center. Available as disk images, several Kodi builds have been released, with OSMC and OpenElec among the most popular.

If you prefer to keep your Raspberry Pi available for other projects, however, Kodi can simply be installed. It can also be added to retro gaming systems (see below). Installing Kodi comes with some caveats, however. Not all add-ons are available, and of those that are, many will be intended to stream pirated content.

As such, we recommend you only install safe and legal add-ons from the official Kodi repositories 7 Security and Privacy Issues to Consider With a Kodi Media Box 7 Security and Privacy Issues to Consider With a Kodi Media Box As more and more people make the decision to cancel their cable TV packages and cut the cord, Kodi continues to grow in popularity.

It doesn’t stop with retro gaming. You probably know that your Raspberry Pi’s default operating system, Raspbian, comes with a special version of Minecraft pre-installed. But did you know that your Pi can be used as a game server too?

Most effectively, your Pi makes an excellent game server for Minecraft, housing the world in which you can play from anywhere on your home network. If you have multiple Raspberry Pis, having one as dedicated server will give you a great gaming experience. This works particularly well if you have plenty of Minecraft fans to play with.

Beyond Minecraft, however, other multiplayer network games can be set up on the Raspberry Pi. Open source ports of Quake, Civilization, Doom, Open TTD and even the official version of Windward can be installed as game servers on your Raspberry Pi 10 Game Servers You Can Run on a Raspberry Pi 10 Game Servers You Can Run on a Raspberry Pi The Raspberry Pi can do many wonderful things, one of which is run as a game server. We show you 10 of the best games it can host. Read More .

7. Robot Controller

There are so many robot-controller Raspberry Pi projects that it’s difficult to settle on a single example. You might, for instance, rely on a dedicated robotics package for your Pi, with the device battery powered and used to communicate and control your robot.

Or you might prefer your own design, built from components you already own. Either way, you’ll need to make the right choice of Raspberry Pi, and for robots it can only be the Pi Zero W. This slimline version of the Raspberry Pi features onboard wireless connectivity, making it absolutely ideal for lightweight robots.

It’s noticeably lighter than the Model B+ boards of the Raspberry Pi 2 and 3, and the low profile means it can be placed in the most efficient position, without worrying about USB ports.

Want some inspiration? Our look at film and TV robots that can be built with a Raspberry Pi should help. Otherwise, if you want to get started right away, robot car kits can be bought online.

Everybody loves stop motion video. From Wallace and Gromit to renowned director Terry Gilliam’s early Monty Python’s Flying Circus work, it never fails to amuse. But how is stop motion made? You can find out with a Raspberry Pi and a dedicated camera module.

Using the Python programming language, a suitable mount (overhead for Gilliam-esque paper craft animation, a standard tripod for clay- or toy-based), and a well-lit area, this is a time-consuming process. Some practice is needed to get good results, and you’ll need to add a sound track.

You’ll also need a breadboard to mount a button (unless you already have a suitable plunger button that can be connected to the Raspberry Pi’s GPIO), and a Python script to snap each image.

9. Time Lapse Camera 5 Ways to Use the Raspberry Pi Camera Module for Time-Lapse Photography 5 Ways to Use the Raspberry Pi Camera Module for Time-Lapse Photography When paired with the popular camera module and portable battery, the Raspberry Pi can be used as a surreptitious camera. With this in mind, I recently captured five stunning time lapse videos. Read More

Combining the Raspberry Pi camera module with a different script creates another use for your Pi: capturing time lapse movies. This is done by taking single frames with a timed delay.

How you then use the Raspberry Pi for photographing time lapse is up to you. You’ll perhaps need a portable battery solution, and a tripod may come in useful again. This time, you may prefer a smartphone tripod (the clamp should fit your Pi’s case perfectly), to keep the device sturdy.

But what should you film? Flowers in the garden, fruit in a bowl, people passing by… perhaps the clouds in the sky, or the changing weather? You’re really only limited by your own imagination, and how far you’re willing to travel to get a good video.

Meanwhile, if your Raspberry Pi isn’t giving you the photo quality you want, or the processing is too slow, why not use it to manage time lapse on your DSLR How To Capture Time-Lapse Photography With Your Raspberry Pi and DSLR or USB Webcam How To Capture Time-Lapse Photography With Your Raspberry Pi and DSLR or USB Webcam Time-lapse photography can really give you a sense of how the world works on a macroscopic level, beyond anything conceivable to the normal human experience of time.

awesome uses for a raspberry pi

Do you have a message you want to share? Need to communicate with a group or community of people who don’t have access to the internet? The answer is radio: and the Raspberry Pi is capable of broadcasting on the FM band!

Before you hit the link, however, it’s caveat time: broadcasting over FM is illegal without a license. Fortunately, the Pi can only broadcast over a short distance, so you should be able to avoid getting into any trouble. Really, this is a proof of concept project. It might prove useful in some remote part of the world… it’s certainly not suitable for setting up in a city center or suburban neighborhood.

awesome uses for a raspberry pi

Another fantastic use for a Raspberry Pi is to set it up as a web server. This basically means that it can be configured to host a website. It might host your blog, for example.

Several methods can be used. You’ll need to get started by installing the right software: Apache and its associated libraries. Or you might install a full LAMP stack, with PHP and MySQL alongside Apache. It’s useful if you also set up FTP.

Once these steps are completed, you can save HTML files into the /www/ directory, and your web server is ready. Or you might install some specific web software like WordPress, or its slimline competitor, Ghost.

To get your website online, using a solution like No-IP.com can get around the lack of a static IP address from your internet provider.

For a more educational approach to creating a website, Google provides the Coder disk image Turn A Raspberry Pi Into A Web Server With Google’s Coder Turn A Raspberry Pi Into A Web Server With Google’s Coder Google’s Creative Lab has turned out some software that helps turn a Raspberry Pi into a basic web server.

Read More

awesome uses for a raspberry pi

Twitter is full of nonsense. Much of it is courtesy of bots, programs that are created with the intention of posting messages. Some of these are useful; they might be updates from your favorite websites, for instance. Many are annoying, however, or even unpleasant. Most of these automated accounts are just targeted spam.

But there are a few useful things you can do, and rather than utilize an online service to publish these messages, you can use a Python application on your Raspberry Pi. As long as your Pi has a permanent connection to the internet, it’s possible to create a Twitter bot.

You’ll need to register a Twitter app via the Twitter website. This enables access to the Twitter API, which the Twython software will interact with. All you need to do then is specify the type of content to be tweeted (anything from CPU temperature to a randomly selected “quote of the day”), with a cron job ensuring the bot tweets regularly. That’s all there is to it!

But what sort of Twitter bot should you create?

13. Build a Motion Capture Security System Build a Motion Capture Security System Using a Raspberry Pi Build a Motion Capture Security System Using a Raspberry Pi Of the many projects that you can build with the Raspberry Pi, one of the most interesting and permanently useful is the motion capture security system. Read More

awesome uses for a raspberry pi

Who is trespassing on your property? Who thinks they can break into your room and go through your things? And just what are they doing with your toothbrush?!

The only way to find the answer to these questions is with some sort of security system. With the Raspberry Pi Camera Module attached, or a generic USB webcam, you can build a motion capture security system.

Note that you will need a high capacity microSD card, or a USB storage device, for storing footage from the device.

This Raspberry Pi project combines the motion software with uvccapture, a tool for capturing the footage from your webcam. The ffmpeg software is also used to for managing the bitrate and time lapse. Once it’s all up and running, you can expect the system to start recording whenever motion is detected. Email alerts can also be configured.

I've been trying to snap the stars and moon -- perhaps even the Aurora Borealis -- using my Raspberry Pi for months. Almost every time, it fails, or at best returns distinctly average photos and... Read More

If stop motion, time lapse, and motion capture security aren’t enough for your Raspberry Pi’s Camera Module, why not try some night photography? For this, you’ll need a Raspberry Pi No-IR Camera Module.

Raspberry Pi NoIR Camera Module V2 - 8MP 1080P30 (RS version) Raspberry Pi NoIR Camera Module V2 - 8MP 1080P30 (RS version) Buy Now At Amazon $24.58

With the IR filter removed, the camera gives better night-time results, letting you photograph what is happening above while you sleep below. This gives you the opportunity to snap stars, meteors, the moon, planets, even UFOs.

For instance, you might use time-lapse photography to track the path of the stars and the moon overnight. Or employ a slow shutter speed to get a trace effect. Whatever your plan for night photography, the Raspberry Pi should suit your requirements perfectly.

16. Build a Network Monitoring Tool Turn Your Raspberry Pi into a Network Monitoring Tool Turn Your Raspberry Pi into a Network Monitoring Tool Network monitoring software Nagios is quick to install and straightforward to configure –but a waste of a full PC. Raspberry Pi to the rescue. Read More

awesome uses for a raspberry pi

Interested in being able to monitor the devices on your network? Concerned about a lack of connectivity, or want quick notice when your blog or website is offline?

The answer is a network monitoring solution. Several are available, but perhaps the most popular is the open source Nagios tool, which is easy to install and configure. With this installed, you can monitor up time, view a visualization of the devices on your network, and more.

Traditionally, it has been installed on Linux boxes, but in truth, it’s a bit of a waste of a full desktop PC or server. However, it is an ideal use for a Raspberry Pi!

All you need to do is download the Nagios disk image and flash it to your Pi’s SD card. For the best results, use a Raspberry Pi 2 or later for this project, as Nagios can get a bit resource-intensive.

We’ve already looked at Kodi as a media center, but there are more TV-based entertainment projects you can do with a Raspberry Pi. In short, you can turn your standard, dumb TV into a smart TV. As if that wasn’t enough, you can even enhance the features of an existing smart TV!

For a TV to be “smart” it should be able to play media from a USB or flash storage device, stream video from Netflix, YouTube, and similar sites, and offer remote control. This is often from a mobile device when it comes to Raspberry Pi projects. Smart TVs should also offer news and weather, and PVR support, which a Raspberry Pi can manage thanks to a USB TV card.

Beyond Kodi (or in conjunction with it) a Raspberry Pi can be used as a Plex client. This means that you have a PC or server running Plex, and have the RasPlex software installed on your Pi. Browsing the server’s media should be straightforward, enabling you to enjoy all movies, TV shows and music stored upon it.

Meanwhile, the Raspberry Pi 3 can mimic the Google Chromecast thanks to MiracleCast. This means you can “cast” video from your mobile device to your Pi. Pretty handy! Other smart TV projects are available, as you’ll discover.

Want to create your own local network drive? It’s a great idea to have a Network Attached Storage device, if only for browsing from a media center. My personal favorite use is as a network drive where I can store all of my writing projects.

Personal NAS drives are very small, too, which means they can be hidden away in cupboards, or on top of wardrobes. The same is true of a Raspberry Pi NAS, which is simply your Pi connected to an external hard disk drive or high capacity flash storage. You might even use an SSD drive.

You can set this up manually with Samba. It won’t be long before your vital data is stored on your home network drive, freeing up space on your PC. Just remember to back up your NAS drive regularly!
