You bought it. Maybe it was a late-night impulse purchase on Adafruit, or perhaps it was a gift from a well-meaning relative who heard you like "computers." Now, that green sliver of fiberglass is sitting in a drawer, gathering dust next to a tangle of micro-USB cables. It’s a classic story. We all start with grand ambitions of building an autonomous drone or a smart mirror that tells us we're pretty, but then reality hits. Linux is hard. Terminal commands are scary.
Honestly? Most people overthink it.
The Raspberry Pi isn't just for coding geniuses or people who want to build robots. It’s a tool. A small, cheap, surprisingly powerful tool that can take over the boring, repetitive parts of your digital life. If you've been looking for things to do with a Raspberry Pi, stop looking for "science fair" projects and start looking for ways to fix your home network. Or your TV. Or your privacy.
The Network Ninja: Pi-hole and Beyond
If you do nothing else with your Pi, install Pi-hole. Period.
Most people don't realize how much garbage is flying through their home Wi-Fi until they stop it. Pi-hole acts as a "DNS sinkhole." Basically, it sits between your devices and the internet, quietly snatching advertisements and tracking scripts out of the air before they ever reach your phone or laptop. It’s not like a browser extension that hides ads; it prevents them from even downloading. This speeds up your whole house. Even your "smart" fridge stops phoning home to tell some server in another country what temperature your milk is.
Setting it up isn't nearly as terrifying as it sounds. You flash an OS onto an SD card, run a single command in the terminal, and then point your router's DNS settings to the Pi's IP address. Boom. Clean internet.
But let's be real—sometimes Pi-hole isn't enough. Maybe you want a dedicated VPN. Instead of paying a monthly fee to a provider that might be logging your data anyway, you can turn that Raspberry Pi 4 or 5 into a WireGuard server. WireGuard is incredibly fast. Like, "I forgot I was on a VPN" fast. When you're at a coffee shop on sketchy public Wi-Fi, you tunnel back to your Pi at home. It’s secure. It's yours. You own the hardware.
Your Own Personal Netflix (Without the Monthly Bill)
Streaming services are getting expensive. Everyone is tired of it. One month you need Disney+, the next you need Max, and Netflix is busy cracking down on your cousin using your password. This is why Plex and Jellyfin are such popular things to do with a Raspberry Pi.
Jellyfin is the open-source darling here. It’s completely free. You hook up a big external hard drive to the USB 3.0 ports on a Pi 4, dump your movie collection on there, and suddenly you have a private streaming service. It has apps for Roku, Fire Stick, and Android. It pulls in all the movie posters and metadata automatically.
There is a catch, though. Transcoding.
If you try to stream a 4K movie to a device that can't handle the format, the Pi has to "transcode" it on the fly. This is where the Pi can struggle. It’s a tiny chip, not a Xeon server. If you keep your files in a compatible format like H.264, it works like a dream. If you try to force it to convert high-bitrate 4K files for your old iPad, it might start sweating. Literally. You’ll need a fan.

Gaming Like It’s 1999 (Or 1989)
RetroPie is probably the most famous project in the history of the SBC (Single Board Computer) world. And for good reason. It’s fun.
You can play everything from the original NES and Sega Genesis up to the PlayStation 1 and even some Dreamcast titles. The Raspberry Pi 5 handles N64 and GameCube surprisingly well, which used to be the "holy grail" for these little boards.
- The Hardware: Get a couple of 8BitDo controllers. They feel like the originals but work over Bluetooth.
- The Setup: Use the Raspberry Pi Imager tool. It literally has a "RetroPie" option in the menu now.
- The Vibe: Build a "Cade." Not a full-sized cabinet, but a small wooden box with an arcade stick and buttons. It’s a weekend project that actually feels rewarding when you're done.
One thing people get wrong is the SD card. Don't buy a cheap, generic 32GB card from the grocery store. RetroPie reads and writes a lot. Cheap cards die. Get a "High Endurance" card from SanDisk or Samsung. Your save files will thank you.
Home Assistant: The Brains of the Operation
Smart homes are usually a mess of five different apps. You have one for your lights, one for your thermostat, and another for that one smart plug you bought on sale. It's annoying.
Home Assistant changes that. It’s a local-first platform that runs on your Raspberry Pi and talks to almost everything. It doesn't care if your lightbulb is from IKEA and your switch is from Lutron. It brings them all into one dashboard.
The best part? It doesn't need the cloud. If your internet goes out, your "smart" house still works. Most commercial hubs (looking at you, SmartThings) get real stupid when the Wi-Fi drops. Home Assistant keeps running. It’s also incredibly powerful for automations. You can set it up so that when your phone's GPS shows you're two blocks away, the porch light turns on and the AC kicks to 72 degrees.
It’s a bit of a rabbit hole. You’ll start with one lightbulb. Six months later, you’ll be soldering sensors to your mailbox so you get a notification when the mail arrives. Don't say I didn't warn you.
The Secret World of SDR and Weather Satellites
This is for the people who want something a bit more "out there." Literally.
You can buy a cheap USB stick called an RTL-SDR (Software Defined Radio) for about $30. Plug that into your Raspberry Pi, and you can listen to almost anything in the airwaves. We're talking aircraft transponders, ship tracking (AIS), and even unencrypted police and fire radio.
But the coolest thing? Pulling images directly from NOAA weather satellites as they fly over your house.
You build a simple "v-dipole" antenna out of some stiff wire, mount it outside, and use the Pi to schedule recordings when the satellites pass overhead. The Pi decodes the radio signal into a literal photograph of the earth. It’s grainy. It’s black and white (or false color). But you caught it from space with a $35 computer and some wire. That’s incredible.

Things To Do With A Raspberry Pi When You're Bored
Maybe you don't want a "system." Maybe you just want a project.
- A Print Server: If you have an old USB printer that isn't wireless, plug it into the Pi. Run CUPS. Now every device in your house can print to it wirelessly.
- A Minecraft Server: A Pi 5 with 8GB of RAM can actually host a decent small server for you and your friends. It’s a great way to learn about port forwarding and server management.
- The "Magic" Mirror: A one-way mirror with a monitor behind it. The Pi displays the time, weather, and your calendar. It looks like something out of a sci-fi movie. It's a lot of woodworking, but the software side is handled by a project called MagicMirror².
- Network Attached Storage (NAS): Stop paying for Google Drive. Use OpenMediaVault (OMV). It turns your Pi into a central file hub. Is it as fast as a $500 Synology? No. Is it enough for backing up your photos and documents? Absolutely.
Dealing With Reality: Power and Heat
Let's talk about the stuff no one mentions in the YouTube tutorials.
Power matters. The Raspberry Pi is picky. If you use a random phone charger, you’ll probably see a little lightning bolt icon in the corner of the screen. That means "under-voltage." The Pi will throttle itself, running slow and crashing randomly. Buy the official power supply. It’s cheap. Just do it.
And then there's the heat. The Raspberry Pi 4 and 5 get hot. If you're running Home Assistant or a media server 24/7, you need a case with a heatsink or a fan. The "Argon ONE" cases are great because they move all the ports to the back, making it look like a real piece of electronics rather than a science project.
Why You Should Care
We live in an age of "rented" technology. You don't own your movies; you license them. You don't control your data; Big Tech does.
Learning things to do with a Raspberry Pi is about taking that control back. It’s about realizing that you don't need a subscription for everything. Sometimes, all you need is a $35 board, a good SD card, and a little bit of patience.
You'll fail. You'll break the operating system. You'll have to re-flash the card and start over. That’s part of it. The "fun" isn't just the finished project; it's the moment you finally get that one line of code right and the LED starts blinking.

Next Steps for Your Pi Project:
- Inventory check: Find a 15W+ power supply and a microSD card (Class 10 or UHS-1).
- The "Imager": Download the Raspberry Pi Imager on your main PC. It's the easiest way to install any OS.
- The First Win: Start with Pi-hole. It’s the highest "utility-to-effort" ratio of any project.
- Community: Bookmark the Raspberry Pi forums and Reddit (r/raspberry_pi). If you have a problem, someone else already solved it in 2022.
Go plug it in. See what happens. Worst case scenario? You have to pull the plug and start over. That's the beauty of it.
