like many pet owners, [Pete] was curious about his bit furry friend’s habits while he was gone. He decided to develop an RFID tracking system to screen their positions. This data would then be offered on the web. An Arduino handles the communication of the data, both to twitter as well as his personal feline tracking site. We were a bit surprised to see that the only data transmitted on the final job was whether the feline was inside or out. We’d like to see a warm map of the cat’s activity in the house.
