Motion detection with a web interface on the Raspberry Pi
Karl Herrick has taken a PIR sensor and hooked it up to his Pi. He’s then used a variety of different software including the Cylon.js framework and Node.js to do the detection and provide a web interface for the sensor. It’s an interesting…
Touch free water dispenser with a Raspberry Pi
Ismail Uddin over at Science Exposure has created a device that detects movement and then dispenses water. He’s taken a Raspberry Pi, a RaspiRobot board, a peristaltic pump and an SR-04 ultrasonic rangefinder module and put them together. His code and write-up is…
Aerial photography from a kite with a Raspberry Pi
Richard Hayler (who has previously done very many cool things with a Pi) has developed his own “kite mapping” rig using a Raspberry Pi. He’s taken a model A+, a camera module, an Xtrinsic Sensor board and a ProtoCam prototyping board, meshed…
Automated waste sorter uses a Raspberry Pi
Harrison Bradley, Jeff Bertel and Marc Welsh studied on the Advanced Mechatronics course at Georgia Tech. They’ve created an apparatus which takes in a piece of waste and then automatically sorts it depending on what the object is identified as: cans…
