10 thoughts on “RFID dorm room door

  1. I’m surprised they couldn’t find an easy way to also lock the door. ie the old string on the bottom of the knob to lock. You’d have to take into affect with slack, but I’m sure there’s ways around it.

  2. My question is how effective are the suction cups? I have used them before in past projects but never for something requiring an absolute position. It seems after a while the box would at best move and not be able to open the door, or at worst fall off the mirror completely…

    That being said, nice project!

  3. amk: what about using the scratch input and having a custom shape or knock pattern? since the door is solid/hollow the noise should travel to both sides of the door. ie. knock, circle circle square knock.

  4. “well now you can implant them in your hand, like they do with dogs.”

    Sif. just implant the chip into your dog. then use the dog to open the door.

    given it would have to be a small dog. but it work work none the less.

  5. “just implant the chip into your dog. then use the dog to open the door.”

    That is Pretty Slick, But why not Key the lock to the RFID Chip, the Government implanted in you when you got you State Mandated Inoculation shots as a kid ?then you’d never loose your RFID Key !
