DIY Secret Knock Detector Lock Is Best Use For Steampunk Mechanical Iris [Video]

Regular garage door openers are dull; why aren't you using a knock-controlled mechanical iris to authenticate visitors instead?  BFarn has been detailing his beautiful secret-knock detecting door project, which hides a tap-sensitive panel behind a huge Steakpunk-styled iris.Video demo after the cut

The build is actually a combination of a couple of earlier projects, one to produce the amazing mechanical iris and the other using – you guessed it – an Aduino to recognize a secret-knock code.  The engraving, meanwhile, was done with a homemade CNC machine.

You'll be pleased to hear that the knock code BFarn is using in the video isn't his regular one, so sneaky YouTube-primed burglars won't be able to break in.  No word on how much it cost to put together.
