I have received the following query. There is no reason for not publishing for everyone to see and comment on. However please try to make comments helpful, not a slanging match as this is a serious project.
I don't think that a weight applied to a pot shaft is a good way to go. The shaft friction is unpredictable. The mechanical design to cause rotation to the same point for a given angle and to prevent the weight pulling the shaft right round is difficult.
If you want to build your own inclinometer I would suggest investigating either toothed / perforated wheels on a common shaft, which you can register with a light beam. This is a transmissive system. Or you could go for a reflective system reflecting from coded patterns painted on a wheel. For an analog system if you painted a spiral of increasing brush-width on a wheel and measured the width where it intersected a fixed beam of light this would be proportional to rotation.
were doing a project on inclinometer, we know that tilt sensors are out in the market.. however we're thinking to do it more on the analog based inclinometer using the potentiometer and a weight attached to it. our problem is we cant come up with a good circuit design for us to start with this one. we're hoping you can impart your knowledge on us.
