The Raspberry Pi is one of those rare pieces of tech that somehow manages to be affordable, versatile, and surprisingly powerful—all while fitting in the palm of your hand. Originally dreamed up as a way to get kids interested in coding, it’s since exploded into a global phenomenon, ending up in everything from home media centers to industrial automation setups. Not bad for a device that started out selling for around $35.
Back in 2006, a group of computer scientists at the University of Cambridge noticed something worrying: fewer students were showing up with programming experience. Computers had become so user-friendly that tinkering under the hood wasn’t as common as it once was. So, Eben Upton and his team set out to create a cheap, accessible computer that would encourage hands-on learning. After years of development, the first Raspberry Pi hit the market in 2012 and it was an instant hit. They expected to sell maybe 10,000 units. They sold over a million in the first year.
At its core, a Raspberry Pi is a single-board computer, meaning all the essential components (processor, memory, USB ports, etc.) are crammed onto one circuit board. It doesn’t come with a case, keyboard, or monitor, but plug in a mouse, keyboard, and screen (even an old TV works), and you’ve got a fully functional Linux PC. Over the years, newer models have gotten faster, added more RAM, and even included Wi-Fi and Bluetooth, but the basic idea remains the same: a tiny, affordable computer for learning, experimenting, and building cool stuff.
What Can You Actually Do With One? Oh, where to even start? The Raspberry Pi’s flexibility is its biggest selling point. For beginners, it’s a great way to dip toes into programming—Python comes pre-installed, and there are tons of beginner-friendly projects out there. But it doesn’t stop there. People have used Pis as retro gaming consoles (thanks to software like RetroPie), home media centers (Kodi runs beautifully on it), and even DIY smart home hubs to control lights, thermostats, and security cameras.
Then there’s the more hardcore crowd. Engineers and hobbyists hook Pis up to sensors, motors, and cameras to build everything from weather stations to robot pets. Schools use them to teach robotics, and some businesses even deploy fleets of Pis for digital signage or lightweight workstations. There’s even a version—the Raspberry Pi Zero—that’s so small and cheap (just $5 at launch) that people embed them into clothing, Halloween props, or custom gadgets just for fun.
One of the reasons the Pi has thrived is the massive community behind it. Forums, YouTube tutorials, and official documentation make it easy to find help when you’re stuck. There’s also a ridiculous number of add-ons (called HATs—Hardware Attached on Top) that snap onto the Pi’s GPIO pins, adding things like touchscreens, GPS modules, or even AI accelerators. The official Raspberry Pi OS (formerly Raspbian) is a lightweight Linux distro optimized for the hardware, but you’re not locked into it. Want to run a Windows variant? There’s a version for that. More into home automation? Load up Home Assistant. There’s even a version of Android that runs on certain models.
Of course, the Pi isn’t perfect. It’s not a replacement for a full-fledged desktop PC—try editing 4K video or running heavy software, and you’ll hit its limits fast. Early models had sluggish USB and Ethernet performance because they shared the same connection (a quirk fixed in later versions). And let’s not even talk about the Great Chip Shortage of 2022, when scalpers drove prices through the roof, and you’d have better luck finding a unicorn than a Pi at MSRP. But even with those hiccups, the Pi remains one of the most accessible ways to learn computing, electronics, and coding. It’s the kind of device that rewards curiosity, whether you’re a kid writing your first line of Python or a retiree building a bird-watching camera that tweets whenever a robin shows up.
With each new model, the Pi gets a little more powerful while staying true to its original mission. Recent versions support dual 4K displays, gigabit Ethernet, and even AI applications. There’s talk of more industrial uses, like edge computing and IoT deployments, but the heart of the Pi will always be in education and tinkering. So, if you’ve ever thought about learning to code, automating your home, or just building something weird and wonderful, a Raspberry Pi might be the perfect place to start. After all, it’s not every day you find a computer that fits in your pocket but leaves room for your imagination to run wild.
