not a kludge

There best be a flush knob disguised as a recliner level on the other side.

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!

Know a little bit about Arduino and care to make your own? Check out his Instructables post!

Instructables user PDRWLSN created this pocket-sized flame thrower not because it's freaking awesome, but to as a way to start a quick fire when you're camping and only have access to wet wood. The gun uses materials readily available at any hardware store with butane lighter fluid as a fuel source and a BBQ ignition switch as a trigger. Below is a video showing the machine failing to melt snow. If any of you are crazy enough to try this, please, be safe.
