Harrison McIntyre has built a Raspberry Pi based project that shoots M&M’s across the room like a pitching machine. Here’s more from RaspberryPi.org:The project relies on similar principles as a baseball pitching machine. A compliant wheel is attached to a shaft sitting a few millimetres above a feeder chute that can hold up to ten M&M’s. To launch an M&M’s piece, the machine spins up the shaft to around 1500 rpm, pushes an M&M’s piece into the wheel using a servo, and whoosh, your M&M’s piece takes flight.See project! // Read more: original article.
