Love your alarm clock but hate how eye-searingly bright it is? Slice up a plastic binder divider to dim your alarm clock (or any other aggressively bright monochromatic display).

At DIY site Curbly Chris Job shares a simple alarm clock hack. For years he had an alarm clock with a nice dim display. When it broke he went in search of a replacement but failed to find one that wasn’t . His solution came in form of a sliced up binder divider (the clear, usually tinted, plastic tabs you put in between paper in a binder). He sliced to fit the display, spritzed it with a little water to help it cling to the plastic, and pressed it in place. The plastic dims the display enough–as seen in the before/after picture above–that he doesn’t need to cover it up to get a good night’s sleep.
