Raspberry Pi

The tiny computer that democratised hardware hacking and Green IT.

In 2012, the Raspberry Pi Foundation released a credit-card-sized computer for $35.

The goal was simple: give children a real computer to learn programming on. What happened was bigger.

Makers, hackers, sysadmins, schools, artists and engineers around the world grabbed it. Pi-hole. RetroPie. Home automation. Media servers. Weather stations. Cluster computing. The Raspberry Pi became the Swiss Army knife of the digital age.

It consumes 5 watts. A standard desktop PC uses 100–300 watts.

Small machine. Big impact.

Over 50 million Raspberry Pi units have been sold. It proved that computing power doesn’t have to mean energy waste — and that the best tool for learning is one you can break without guilt.

Green IT didn’t start here. But the Pi made it tangible.
