Mike Moyer was tired of seeing Samsung commercials for the Family Hub refrigerator with the built-in camera and decided to make his own using a Raspberry Pi, a webcam and a light sensor. Every time the fridge is opened, the Pi takes a picture of the contents. He used a buck converter to take the fridge’s power supply down to 5V for the Pi and also created a website where the last picture taken was published. You can see the current picture on the website here. Mike’s done an explanation video which you can see below and you can visit YouTube for a bill-of-materials (check the video description). The Python program he wrote is available here.
