The company Pedigree in Spain in collaboration with the advertising company Saatchi & Saatchi, made an amazing device-vest for dogs called Posting Tail, which allows them to take selfies photos and share them on social media.
No it's not a belated April Fool's joke, but this is real construction. The Posting Tail device, as you can see in the video below, works by using a sensor movementς που βρίσκεται στην ουρά του σκύλου και μέσω ενός επεξεργαστή Raspberry Pi αισθάνεται πότε το dog you are especially happy (when he is constantly wagging his tail), so he signals the camera to take a picture and upload it immediately to Facebook.
Raspberry Pi's programming can sense when your dog really is happy and is not confused with the simple shakes it does with his tail. Apart from these, the package also includes a GPS so that you can see where your dog took the most pictures and he was more happy.
Her vest Pedigree is not available to the general public, but you can go to Pedigree.es and sign up to earn it for one week.
