Programmable-Air is a hardware kit that allows makers to control air. It was developed by Amitabh Shrivastava under the guidance of Kari Love at ITP, NYU.
Programmable-Air was built to control inflatable soft robots, but it has since been used to make everything form air spray gun and pick and place tools to breathing balloon sculptures and Halloween props.
The guiding principle behind Programmable-Air is cost effectiveness, portability and ease of use. And it is completely open source(OSHWA UID #US000159)
