Tweeting Cat Door Keeps Unauthorised Animals Out Of Your Home

If you've ever had a stray cat come in through your pet door at night, you know the chaos thhat can ensue. To eliminate that issue, you can construct a secure pet door that only lets your cat or dog in after scanning the RFID tag on their collar. For added excitement, the system also takes a webcam photo of your pet entering or exiting and tweets the event.

This project started as an Instructable from user e1ioan, but has now grown so popular that e1ioan has created a site for the project and offers kits for those who need a little extra help.

It isn't a cheap project — you'll need a RFID reader, a micro-server to act as a latch control, a webcam, a router running Open WRT, and several semiconductors, capacitors, resistors and other electrical hardware. The source link below offers loads of schematics, step-by-step instructions, and the complete code needed for the project. If you're a techy pet-lover this might be for you.

    The RFID tag is brilliant idea, but why the need to tweet about it? No one cares about the coming and going of your dog or a cat. If you want to create a photo record, fine, set it up on a person server. Why is there the need to post it in a public forum?

      You really haven't been on the internet long, have you Dann? :P

      The twitter part is a little twee, but it's a nice demonstration of getting the system online and sending notifications. Getting an email or similar of what my cat's up to when I'm not at home does appeal a little. Especially if I think the little bugger's lost and am out looking for him. :P

      But my quick read-through of the linked article does make it pretty easy to just build the arduino system in the door and leave out the openwrt box and online bits.

    Or you could just get one of these: www.sureflap.com.au

    Been around for years.

    my cat usually comes in to the house at a fair speed (usually being chased by other cats, the speed at which this works would probably give me a snub nosed pussy.

    Great idea but my wife wants a "mouth inspection" built-in to ensure they aren't carrying a disheveled mouse, bird or live snake (as has happened a few times), :o)
