Secret Knock detecting Entrance to my garage / workshop

This is (what I think is) a great example of the kind of fun, inspiring projects that come out of communities like Make, BoingBoing, and the DIY nerd world in general. I combined Chris Schaie's beautiful Mechanical Iris, Steve Hoefer's Secret Knock detecting Arduino code, and an engraving made with my scratch-built CNC-Router to make the entrance to my garage/workshop/lab a bit more special. These people all inspire the hell out of me, and I just want to feed a little bit of that back to the source.

A short video of programming in a new knock:

    door opens.

  6. Cool concept but we know your secret knock now 

  7. Where did you get your sheet brass?

  8. Ask, and it shall be given you: seek, and you shall find: knock, and it
    shall be opened unto you Matthew 7:7

    That’s a cool iris alright, but do you really have the door motor connected
    to a piezoelectric device that recognizes your “secret” knock? Cos THAT is
    what I would like to learn how to make. You could sell the units ready to
    program and install…

  20. I FAPPED.

  21. I can use a zoom-sniper mic from 200ft away pick your knock and later open
    ur garage. Yet its an awesome work..using steampunk iris does all the
    magic.
