Since we were making combination/safe lights, I thought this was a cool project to post.
This safe makes your face the key to unlock it! This project will shows you how to use a Raspberry Pi and Pi camera to build a safe that unlocks itself using face recognition. The software for this project is based on algorithms provided by the OpenCV computer vision library. The Raspberry Pi is a perfect platform for this project because it has the power to run OpenCV, while being small enough to fit almost anywhere. Here is the tutorial.
