Whether you are in the market for a Pi 4 or you already have one sitting alone in a drawer, you are probably in need of some cool project ideas. Don't drive ̵
Why are these projects suitable for Pi 4?
Most of the projects we list are relatively simple. They do not need much programming experience, and they are popular enough that you will have no trouble finding guides on Google or YouTube. But really, why are these projects suitable for Pi 4? Why not use cheaper Pi 3 Model A +, instead?
It all comes down to specifications. The Pi 4 features an upgraded Broadcom BCM2711 SoC with four 1.5GHz Cortex A72 CPU cores (ie a good CPU), a gigabit ethernet port, two micro HDMI ports for dual 4K displays, and three RAM choices ( 1, 2 or 4 GB). These specifications (and especially RAM) make the Pi 4 much faster than any previous Pi computer. Just make sure you get the right charger for it.
While can use older versions of the Raspberry Pi for some of the projects we have listed, they do not offer the speed, flexibility, or reliability of Pi 4. These features make a big difference when working with a Pi-based computer, server, Plex media center, gaming console or smart home device.
Build a New Computer
Old models of the Raspberry Pi are relatively powerful, but not powerful enough to build a reliable computer. Thanks to Pi 4's upgraded RAM and CPU (not to mention its dual-display capabilities), building a Pi-based desktop, laptop or tablet is easier than ever.
Here are some Pi 4 computer projects that may appeal to you:
- Desktop : Raspberry Pi 4's impressive RAM and CPU specifications make it a great candidate for desktop use (whether you need a Linux system or Windows PC). Grab an official Pi 4 Desktop Kit and head to town! And don't forget the Pi 4 supports dual external monitors.
- Laptop : Pis small form factor translates well to small PCs and especially laptops. We suggest you work with Pi-Top laptops (they are simple and inexpensive). Pi Foundation also has its own list of laptops. Just make sure the set you choose works with the Pi 4 before you buy it.
- Tablet : There is no Pi 4 tablet set yet, but you can attach the Pi device to the back of an official or unofficial touch screen with a little velcro (now may be a good time to buy a Pi 4 matter too). This may sound ridiculous, but it's a great way to take your Pi on the go.
Of course, a Pi PC is not a measure of an average desktop computer. If you have already fixed on desktops, laptops and tablets, it may be time to focus on another Pi project.
Enhance your home network
On a basic level, the Raspberry Pi 4 is a cheap, small computer. While this limits the ability to function as a modern desktop PC, it makes Pi a fantastic candidate for just about any home networking project. Instead of relying on clunky old computers to run BitTorrent and development servers, you can defer everything that works to credit card size Pi 4.
Here are a few home network Pi projects to get you started:
- Server : Raspberry Pi 4 can be a great gateway to web and software development. Just follow the official guide from the Raspberry Pi Foundation and you're good to go!
- NAS Box : NAS devices are expensive, but they are good for local storage and streaming solutions. So, build your own NAS box with a Raspberry Pi! All you need is a NAS case and some instructions.
- Pi-Hole : Ad blocking extensions are great, but they only work in your browser. If you're tired of ads on your phone, in software, or on your TV's YouTube app, it's time to block network-level ads. A Pi-Hole gets the job done, and it's easy to set up.
- BitTorrent Box : If you are a good BitTorrent who likes to seed 24/7, you always need a machine dedicated to the dry. The Raspberry Pi 4 can do just that, and it's much smaller than a new PC or laptop.
Hmm, computers and home servers. This doesn't sound like much fun. If you're looking for a project to entertain the whole family (or just yourself), it's time to move on to some gaming and streaming Pi projects.
Enjoy Pi-Based Gaming and Streaming
It seems like everyone has a Pi connected to the TV these days, and for a good reason. Raspberry Pi is arguably better (and cheaper) than most streaming sticks and game consoles, and software like RetroPie and Kodi are easy to set up.
Pi 4's upgraded RAM and CPU make it an ideal candidate for hiccup-free home entertainment projects. Pi Projects:
Most of these projects are easy to expand. Do you want to build an arcade machine? Do it with the RetroPie software! Want to make your bedroom TV a flow machine? Attach a Pi to it!  Expand Your Sma rthome
Smarthome devices are expensive, and they don't always work as well as you expect. In addition, they are impossible to service and may be out of date after only a few years. The solution? Build your own smart home devices!
These projects are relatively tough (and require some research), but they are worth the effort. Here are some ideas to get you started:
Again, Pi 4's updated specifications make it ideal for smart home builds (unlike older Pi models running at lower speeds). Just remember that most of these smart home projects require some extra purchases, such as Arduino boards, digital cameras or touchscreen displays.
The Pi projects we have listed vary in difficulty, but most are a great starting point for your journey into Pi Judgment. You can also easily expand them in unique ways.
If these projects aren't enough to get your Pi juices flowing (gross), it might be time to dig through the official Raspberry Pi blog or forums. These platforms are regularly updated with neat projects and Pi software that will interest you.
