I built this for our office at 42Floors -- let's us open the front door automatically during the week and during special events.

Very clever. I love technology that uses existing "dumb" infrastructure to make it more useful. The Misfit Bolt, a connected lightbulb that plugs into existing sockets, is another example of this. This could be particularly useful for businesses that want to automatically buzz people in during business hours.

@rrhoover Is there a particular reason you gave the Misfit Bolt a shout out? The most popular connected lightbulbs that have preceded the Bolt work in existing sockets. Just curious.
