Orlando, FL 32807 Phone: 407-678-6900 FAX: 407-677-5765 I considered getting one of their Hall transducers for my own digital compass, but I ended up working on another project. None of their transducers seem particularly well suited for magnetic fields as low as the Earth's. You'll probably need a lot of drive current, and a lot of amplification. I don't know if There are any other big Hall transducer manufacturers ( Bell is a manufacturer, not a distributor). If F.W. Bell doesn't have what you want, I have two suggestions: o There is a British company that makes auto pilots for boats ( I think it's called Navico, but I'm not sure. Try contacting them and finding out what they use. They're the only ones I know of who use the Hall Effect for their compass. Others use a flux gate compass. o Consider using a flux gate instead of Hall Effect for your compass. Let me know if you need more Info on these two suggestions. I have some info I can dig up on the subject. Pedro Pedro Monteiro / Florida Atlantic University - Pedro@acc.fau.edu
