The Raspberry Pi 4 Model B is the latest version of the low-cost Raspberry Pi computer platform. In short, it’s a credit-card sized electronic board that can function as a stand-alone computer.

The Raspberry Pi 4 can do a surprising amount. Amateur tech enthusiasts use Pi boards as media centers, file servers, retro games console, routers, and network-level ad-blockers, for starters. However that is just a taste of what’s possible. There are hundreds of projects out there, where people have used the Pi to build tablets, laptops, phones, robots, smart mirrors, to take pictures on the edge of space, to run experiments on the International Space Station — and that’s without mentioning the more wacky creations — teabag dunker anyone?
