We've all been there. You wake in the middle of the night, it's still dark, but you are not sure how many precious hours you have before work (or minutes, even, in the winter).
For some (not me) a clock will be clearly visible, but Gadget Master Nirav Patel needs glasses and the world can seem blurry without them....
Yes, he could stretch to put on his glasses and then clock the time (waking himself up in the process) or he could - as an
ingenious inventor - create a device for displaying on the ceiling how much time remains for sleep, using a Lego-housed Arduino-based laser device.
