I read that link (using google translator! ) and I think (!) he has given up but then perhaps suggests using round magnets, like fridge magnets, and the Hall sensor.
I don't know enough about how the Hall sensors work to replace a potentiometer or what 'type' or 'value' the sensors should be. It's a great idea so I'll have to study it.
