Submission CATaLOG - An RFID cat tracker-> 2

peterprior writes: "I've been building an RFID cat tracker — dubbed CATaLOG — for the last few months using an Arduino Microcontroller and the newly available ethernet shield. I've documented my progress and how I went about it over on the project pages as well as doing an O'reilly Ignite presentation on it a few days ago. You can view the live cat status or follow the cats over on Twitter."
