After reading the construction article "Build A Solid State Compass"
( June 91, Radio Electronics ) I thought of a different application
of the thing but have a question for the net.

I understand Hall Effect Sensors produce a voltage when magnetic lines
of flux pass through their body at a right angle. Does the output vary
depending on the polarity of the magnetism? That is, is the output
different depending on whether you place the North end or South end
of a bar magnet next to the device?

Also;
Has anyone out there built one of these?
Anyone know who sells HES in low quantities? (Sprague UGN3503U)
Anyone interested in how mine turns out :-)


Thanks,
John
