The video shows a test rig I built that uses an Allegro A1302 hall effect<br>
device. The idea is to build a drop-in replacement for any<br>
voltage-dividing potentiometer application. It's crazy simple to build.<br>

You can buy the A1302 from Jameco for about $1.30 each. They take 5V in<br>
and spit out a 0..5V signal based on the position of two opposing magnets.<br></blockquote></div><br><br>And you can plug these directly into one of Leo Bodnar's boards for an instant joystick axis.<br><br>What's the orientation/type of the magnets in your setup Gene?<br>
