Laser-based 'clock' shortens beam as wake-up time draws closer
It's probably not the clock you need to build if being punctual is your modus operandi, but it's sufficiently nerdy nonetheless. One Nirav Patel -- which may or may not be related to our own Mr. Patel -- decided to hand craft his own "sleep remaining indicator," which utilizes a slowly rotating servo, a laser beam and a timer in order to work its magic. Put simply, the beam gets shorter and shorter as one's wake-up time draws near, but oddly enough, you'll never be able to see its awesomeness if you're actually sleeping. Quite the conundrum, no?
