Background: I'm are building an airplane simulator with old components from a cockpit that I hook into the simulator. In this model I have a couple of steering controls for the throttle, nose wheel and the breaks.
First I tried to solve these controls with simple potentiometers but the accuracy was worthless, for example the throttle became was really jittery and the nose wheel felt nervous! :) Then I got to lend some really expensive digital rotary encoders stuff that needs a whole new computer together with a extreamly expensive PCI card ($2000+). This works of course perfectly but in some weeks I need to return the hardware.
So now I need to do something simular (with almost the same precision).
- Can a newer analog potentiometer have the same accuracy (in "steps" of 0.5 deg)?
- Is there any cheap (max $200) absolute rotary encoders that is compatible with the arduino? (something like 1000 steps per rotation)
- Can I do this in a whole new way using gyros or something else?
