Alarm Clock Hack Automates Window Blinds So You Rise and Shine
Mods don’t get much simpler and more useful than this: It’s an alarm clock that whisks open some window blinds when the alarm goes off, so the sun can tempt you out of bed. There’s a microcontroller to handle detecting the alarm signal and to drive a servo wired into the blinds, and some switches to override the alarm and open or close the blinds on command. Check the video of it in action.
