If it's using the sensor with a small magnet, it's a re-re-recycled project.
A couple years ago, they featured a compass (which I built), then the
featured a talking compass that used a nw-unavailable ISD chip. This sensor
is not super-reliable. They -- or Electronics Now -- had a project that
featured hacking into Radio Shack's flux gate compass (~$50?).
