Chips and corresponding magnet:

These are cheap SMD ICs that can sense the rotational angle of a magnet with 10-12 bit resolution (and accuracy), and they seem extremely easy to interface with and use. It would be nice to have the magnets and chips available from the same place, as well as a breakout board with mounting holes and the chip already on it, to make external alignment easier (the better the magnet is aligned to the IC, the more accurate it is). The only product I could find that uses these chips is a US Digital encoder that has a huge markup for low unit counts:

Anyway, hope you guys find this worth looking into, they look pretty nifty for hobby robotics.
