Following the arrest and conviction of Andrew Banks for urinating at the Westminster memorial dedicated to PC Keith Palmer, someone sent me a video of this fabulous Raspberry Pi-controlled project. The charmingly-named “That Engineer Guy” has been helping a Southampton-based friend out. The friend owns a shop and, disgustingly, people (I assume mostly drunk) have been using his back doorway as a public urinal. By using a Raspberry Pi, a water valve and a camera programmed to detect movement, The Engineer Guy has developed a solution by creating a spray of his own – from a water down-pipe! The lesson here? You never know who’s watching!
You can watch all the attempts here, if you really must!
