      Hi everyone
      Firstly excuse me for my english :D

      I was doing some research on internet for my personal projet and this forum comes out!
      Exactly what I wanted to do.
      Using the NFC ring, an arduino board and a NFC module like elechouse V3 and some other stuff to build a "box" with a NFC lock.
      And all what I found to build my box you are talking about it here!

      I have one question
      I will use a wood box with a thickness of aproximatly 1cm( don't realy know)
      Are you sure that the NFC module can read with this distance?

      Maybe we can help each other cos I see here that you are trying to do the same thing?

        Hi mate, your english is fine. :-)

        They've got a good idea here, I'd love to see someone do it with one of these; http://www.ebay.com.au/itm/New-6V-Electric-Drawer-deadbolt-Locksmith-Latch-Cabinet-Door-Lock-/271309848282
        They look like they'd be pretty much perfect for such a thing.
        I'd say yes it should read through that, I've had my elechouse unit reading a reasonable distance away with both Alpha and Normal rings perhaps 30mm or so from the top of the unit. So it should work, just experiment with it a bit. Set up the arduino to trigger a LED and then put your building material on top of the reader and see how it goes. If not then you can always build a housing for the reader outside the box and keep the arduino and latch on the inside where they're safe from interference.

          I ordered everything except the nfc ring, just to be sure that my system works well with a couple of nfc tag.
          I decided to minimize the cost with chinese products.
          So the lock system will be something like that


          I'll use very cheap materials to show that with only less than 50 bucks we can make something reliable.
          Just the NFC ring wich is a bit expensive compare to te rest, but it worth the price :)
          Photos and feedback as soon as I can.
          An instructable too.

              My PN532 elechouse NFC module is finaly arrived!
              I still don't really understand the difference between I2C of HSU mode.
              Is there someone who could add me on skype so we can discuss about this module and how it works?

                Hi nairod, could you pm your skype address if you still need help? I'll add you and see if we can sort through it.
