As a kid the only thing I ever wanted was night vision goggles, not the toy kind, but the real kind that would let me see across the field without issue. Now, thermal imaging isn’t night vision, but it’s a close second in my opinion. The Flir One is an iPhone case (for 5 and 5S) that turns your phone into a thermal imager. The device works by using the camera built into the phone and adds some sophisticated technology that enables it to spot hot and cold spots in your house and outdoors. Hot spots where there shouldn’t be could indicate a problem, much like cold spots could indicate a leak or weak insulation. Or it might just be a cat outside that’s knocking over your trashcan at night. No idea if this actually works as intended, but it’s still pretty damn cool!
