TechSource: 5 of the Best Raspberry Pi Projects Out There

5 of the Best Raspberry Pi Projects Out There

Posted: 04 May 2015 08:50 PM PDT

Raspberry Pi, when first launched about two years ago, became an instant phenomenon. After all, who could have thought of a $35 computer that lets you browse the web and does most of your office work? What is even more surprising is the reception it got from average users. Usually, one would expect a bare-minimum $35 board computer that runs Linux to be popular only among developers or geeks. However, as many as 100,000 Raspberry Pi units were sold on the day of its launch eventually selling more than 2.5 million units till date.

Completely open-source, Raspberry Pi lets you do most of the basic tasks you'd normally do on a full-fledged desktop. You can browse the web, you can create documents, and you can even play music and watch videos. When it comes to desktop computers, Raspberry Pi is a veritable "Starter's Edition." Since its inception, the project has made common computing available to parts of the world where owning a desktop was once considered a luxury. Moreover, it has also spurred a flurry of interesting projects that take this tiny superboard to a whole new level. If you are ready to show your creative, geeky side, then read on as we cover some of the best Raspberry Pi projects out there.

1. Turn Raspberry Pi into a Low-cost Coding Tutor for Kids

We've already covered a list of the best programming courses out there. However, as good as these courses are, learning programming can be a tough ordeal for kids who need a more hands-on approach to code. Instead of letting them mess up your production computer, you can buy them a little Raspberry Pi box, hook it up to a monitor, and let them code their heart away. A good programming language that's up to this task is Scratch that turns programming into an activity that's geared towards kids, making the whole process fun and enjoyable to them. In fact, this combination of Pi and Scratch can make programming accessible to places where kids who don't have the privilege of owning a computer, thus making it easy to spread knowledge everywhere.

2. Turn Raspberry Pi into a Media Center

Did you just say media center? Yep, there's a lot this little board can do that you won't usually expect it to do. What's great about Pi is that it supports 1080p out of the box with a tiny-but-powerful GPU running behind the scenes. Combine that with the Xbian project, you got a full-fledged media center on your hands. XBian is a small, fast and lightweight media center distribution that is designed for Raspberry Pi that brings the latest of XBMC to your mini-computer. It's a great, cheap investment if you're someone who likes watching a lot of movies.

3. Turn Raspberry Pi into a Car Computer

A very interesting blog post by developer Andrei Istodorescu shows you exactly how you can turn Pi into a PC that sits in your car. This means that you'll be able to watch your favorite movies or TV shows in your car. While that's a perfect idea for a romantic date, just make sure that you're not doing Game of Thrones marathons while driving. The blog post explains pretty much everything you need to do in order to install, configure, and get it up and running. The approximate cost of the parts requires comes down to about $200. However, as costly as that sounds, compared to the $25 board, it's a worthy investment for every geek who also loves her car.

4. Make a Wearable Raspberry Pi Computer

Envious of your Google Glass-sporting friends? Or maybe you're too privacy conscious to try the search giant's latest wearable. Whatever the case maybe, geeks and privacy enthusiasts can make use of Pi to create a DIY wearable that they can brag about to their friends who are busy drooling over Android Wear, Google Glass, and other wearables. While no way near perfect, this project can provide a full-powered desktop computer that you can use wherever you are. Even while walking. Although the cost of this project is about $400, it's a justified investment for every geek out there who wants to have a great learning experience.

5. Turn Raspberry Pi into a Universal Remote

Instructables has another cool guide on turning your Pi computer into a universal remote. Though you'll need some parts to get that working for you, those little investments are worth it if you're a lazy geek who loves to control everything from the couch. Also, it's a great learning experience for anyone who's interested in knowing more about the LIRC or tinkering with electronics. A bit tough to get working overnight, this project can be treated as a huge learning experience more than just a way to create a universal remote. You can also pair this off with XBMC and then create an ultimate media center with remote and everything at a very low cost.
