Multicolored Keyless Entry System

Posted by timothy on from the simon-says-open-up dept.

mollyhackit writes "Here's a how-to guide for building a keyless entry that uses color identification instead of numbers. All eight buttons are initially blue; as you press the individual buttons they change color. Cycle the colors to your particular pattern, and you're in. This lock obviously wasn't designed for high security use since anyone in the same room would be able to see you and your amazing technicolor dream lock's pattern; it's just a fun project and will keep the youngins out of your workshop (timer prevents brute forcing). The RGB buttons are monome clones from hobby shop Sparkfun."

      I would be equally "fun" to replace non-color-blind peoples front door locks.

      I'm fully colorblind, that's right, black and white. Color coding a lock is no big deal, just get the master key. I think a ten pound sledge would do.

    That is why I always insist that my PIN uses all the available numbers in the numeric keypad.

    but after using the sledge hammer, each time I would have to buy a new door. Got expensive. I'd recommend a key

    it.slashdot.org has brown as its colour, not green :-) So it is not the colour blind, but rather, poor design that makes the it section look crappy brown.

    Yay. You just proved me colorblind.

    Easy solution: match each color change with an audio alert.

    Any suggestions for my colourblind + tonedeaf friends?

    Non trivial math: how many people can integrate sec^3? How many B&E type criminals can? I can't, but my crowbar got me through math class before and can do it again.
