Raspberry Pi projects can leverage the computing chops of the tiny SoC to build something very cool. In my college days, it was mostly about attaching a sensor to the Pi and then creating a device out of it. But as the computing prowess of Raspberry Pi grew, it became a perfect fit for self-hosted services. You can run customized operating systems on it, or apps that can help you switch to privacy-focused alternatives and save a lot of money on subscriptions.
