dCompass: Digital Compass for LEGO® MINDSTORMS® NXT - a compass sensor for LEGO MINDSTORMS NXT

I just received the information below in an email from Dexter Industries... This low-cost device appears to add needed functionality to LEGO NXT robotics resources... Certainly worth a look to understand the concept and approach.

Detailed Description

The Dexter Industries dCompass is a compass sensor for LEGO MINDSTORMS NXT. This compact sensor detects magnetic fields for navigation. Using a magnetic sensor, the sensor is able to measure the earth's magnetic field and returns a magnetic heading, telling you which way your robot is heading.

The device can be used without calibration and can be calibrated with software to account for magnetic fields to deliver a highly accurate compass heading.

The sensor is supported in NXT-G, Labview, and RobotC.

The sensor communicates with the NXT via I2C and can be placed on any port.
