You might think you’re being discrete when you check your pants to ensure your fly is zipped up, but it can look a little awkward if you’re not alone. Instead of waiting for the embarrassment of just being told you need to zip up, check out this brilliant hack that makes it easy to subtly check the status of your fly.
Randy Sarafan, the Technology Editor at Instructables, is back with an even more useful tutorial this time. Using conductive thread, a small circuit board and a vibrating motor, he’s created a near invisible device you can use to make sure you’re zipped up.
Tapping a button in your pocket produces a vibration if you’re all good or nothing at all if you need to slip away and deal with the problem. And, like all fun hacks, have fun explaining this one to airport security if you try to fly with it. They probably won’t be too understanding of your vibrating pocket.
