That's why the best polls are informative polls, because they're a place for people to say, "look how smart I am," (and a place for us to learn from them) in a more free manner than having to be coerced into a more specific topic.
My second choice is magnetic poles, because I'm now dealing with them working for Boston Dynamics. You would wonder why people would pay lots of money to use primitive ol' magnet-and-wire contraptions such as resolvers. Well, the answer as applies to a lot of other seemingly-outdated military-grade crap is because they are fucking rugged, super-accurate (often down to 1 arc-second or below) and operate in extreme environments (heat, cold, dust, smoke, etc) that would defeat lesser positional sensors.
EF: I never found anything near as reliable and durable as those old magnetic resolvers. I have a shoebox full of 'em somewhere... all sorts of them. Some of them can do some really neat rotation calculations.. all magnetically.
Have you used them with Goertzels to recover phase?

Maybe good polls require time and effort to construct. Thus they are in limited supply.
The lower I set my standards the more accomplishments I have.
