Re: Pendulum type elevation measurement
My experience with pendulum elevation was the same as Greg's. The hysteresis made it unworkable. No matter how much I increased the weight or pendulum length I could not get acceptable results. I shelved the project for the time being. - Howie AB2S
These days, hacking an electronic level makes more sense, I think. 73, doug

Come to think of it, if the sensor in a new optical mouse can detect when it moves, even fractionally, over a surface, couldn't the same sensor, mounted close to a vertical mast or horizontal cross-boom, detect when those shafts rotated?
