After receiving many emails requesting Instructions and Kits for building the "Tweeting Cat Door
", I decided to make a version that is stand-alone and doesn't need a computer to be run and that is easy to be put together by anyone with a soldering iron and a little time on hand. All the software is available to download, but feel free to modify it to make it better or to better suit your needs.The Tweeting Cat Door works as follows:
When a pet tries to enter the pet door, a RFID reader will read the RFID tag that your pet has on the collar. If the tag is authorized
, the latch of the pet door will open, a picture is taken of the pet, and uploaded to Twitter along with a funny random message, for example: "Penny is in playing with a ball of yarn."
The pet door works in the same way when the pet tries to go out. A picture is taken and uploaded to Twitter along with a message, for example: "Gus is out to play poker with the fellas."
The messages are chosen at random from a list of possible messages.Here are some examples:http://twitpic.com/2a7q32http://twitpic.com/2uehbshttp://twitpic.com/2uc1ryhttp://twitpic.com/29jcd2
Here is @GusAndPenny
Sadly, there are no recent updates @gusandpenny. Gus died a while back (probably a fight with a raccoon or other cats?) and not long after, Penny followed.Note:
The twitter part of the project is optional. You can just build the Arduino controller, the latch to lock/unlock the pet door, mount the RFID reader and the latch on the door and you are ready to go. Your pets would be "sorted" by the RFID tag they are waring.
Here you'll find detailed step by step instructions and kits with all the components (you can buy kits, PCB, preprogrammed Arduino chip, etc, by contacting me). By following the instructions on this page, you will have - in no time - your own RFID enabled, twitting pet door, just like the original Tweeting Cat Door.
How does the RFID (Radio-frequency identification) enabled pet door works?
Each pet will have a small RFID tag on the collar and the pet door will open ONLY for your pet for entering the house.
The RFID enabled pet door has 3 settings that can be controlled by pressing a button. For each setting a LED will light in a different color:GREEN
- Open, your pet is allowed to exit the door and to enter the door.BLUE
- In-only, your pet is allowed to only enter the door (for example at night when you want your pet inside)RED
- Locked, the door will stay locked and no exit or entering is allowed.
Note: The entering through the door is controlled by RFID, exiting is controlled by a infrared beam.
