Raspberry Pi

Tiny but powerful and deliciously named, the Raspberry Pi is the brains of the food computer. In Melanie’s classroom, it’s connected to a fan to cool the food computer, to an adjustable temperature sensor, and to a customizable grow light that changes based on each plant’s needs. And of course, all the code that controls these functions is open source.

Food computers

A food computer is essentially a tabletop garden. It’s a foam box that contains everything a plant could need to grow and thrive: water, food, light, and a controlled climate. A small computer called a Raspberry Pi controls all those elements via a network of sensors, lights, and fans. Students at Green Street Academy have built a hydroponic system using plans for an affordable food computer.
