It’s been a year since the super-powered Raspberry Pi 4 officially landed on store shelves. And whether you have a Pi 4 hidden in a drawer or stuffed in your Amazon Wish List, you’re in serious need of some project inspiration. Here are 18 killer projects for the Pi 4.
In July 2019, I wrote 16 Cool Projects for Your New Raspberry Pi. It’s a straightforward list of (mostly) entry-level Pi projects, like building a Plex server, a BitTorrent Box, or a custom smart speaker. Now that the Pi 4 is a year old, I want to focus on weird, more ambitious projects, like reviving vintage electronics or crafting social media bots. I wouldn’t call any of these projects “difficult,” but some of them require soldering skills or electronics experience.
Why Did You Choose These Projects?
We’re looking at the Pi 4 because it’s one of the most capable consumer-grade microcomputers available to date. It opens the door to projects that aren’t reliable (or doable) on the Pi Zero, the Pi 2, or even the respectable Pi 3 Model A+, yet it carries a price tag well under $100.
Thing is, there aren’t a lot of projects that are exclusive to the Pi 4. Many of the projects listed in this article will work on slower, less powerful microcomputers. You can get away with Steam Link on the Pi 3 A+, or build a retro radio from a Pi Zero. But the results are much more impressive when you use the powerful Pi 4.
I chose to include these non-exclusive projects because they benefit from the Pi 4’s four-core 1.5 GHz CPU, its gigabit Ethernet, its enhanced Wi-Fi chip, and its impressive RAM selection (2GB, 4GB, or 8GB—the 1GB model is discontinued). Some of the project guides that I link to utilize the Pi 3, but you can follow them line-by-line for the Pi 4 and find yourself with a faster, more reliable, and more enjoyable result.
Alright, that’s enough of that. Here are 18 more projects for your Raspberry Pi 4.
