Item Lock with Wrong Item Detection [Minecraft Tutorial]

An incredibly compact item lock that allows you to obliterate those thieves by having a wrong item detection system. There are two outputs, one for the correct item and another for all wrong items. Alternate design by a great redstoner who I'm subbed to but somehow missed this video he made weeks before my one!: http://www.youtube.com/watch?v=M1bpb5y9exk (ps sub to him he's awesome) Don't forget to leave a like if you enjoyed the video, it helps a lot! It requires minimal redstone and is easy to set up meaning it is perfect for those using survival and yet it's reliable enough to be used for map makers and like as well! Using snapshot 13w06a this redstone contraption is able to work :D 1.5 snapshots or newer are required for this to work.
