Ben Brabyn wanted to encourage his friends and family to smile a bit more and so he came up with the solution: marshmellows! A Raspberry Pi and a webcam are used to detect a smiling face and then a hacked toy catapult is used to launch marshmellows at the user. He’s used a MotoZero motor controller from The Pi Hut to control the catapult and then written some Python code using OpenCV to read the image from the webcam and detect the smile.
