Steve Hoefer at Grathio labs shows off his Arduino based door opener, which responds to knocks on the door bye timing the gaps between the sounds. If the gap matches the programmed knock, it unlocks. Let's never use keys again!

From the submitter:

A while back I decided to see how my coffee maker worked. I busted it open and by the time I figured things out, I couldn't put it back together (broken). So I decided I didn't want to buy a new coffee maker and I built this stand for the machine innards. The reservoir was built into the old machine, so I had to add the bottle to hold the water as it heats up. It works great!

Okay, the true American is to pay someone else to do it. But this is a close second. Happy 4th! ~NSHA

If it were my job to run around in a Barney costume and hug little kids all day, I would want nothing less than an industrial sized air conditioner.
