In a country where sunlight is often hard to come by, many Brits turn to tiny pockets of clear skies for their vitamin D production. In this installment of The Gentleman Maker, Robin Mitchell creates his very own Sun Informer, a device that detects intermittent sunlight. When it senses that pocket of sunshine, the device alerts all sun-deprived people in the immediate area, encouraging them to head outside for a few precious minutes. But in an effort to avoid sunburns, after 15 minutes, the device sends out another alert, warning users against spending too much time in the sun.
