Does anyone sell a RC hobby "servo motor" which outputs its position? I guess I could drill a hole into one and run some wires into it but I rather not. What I really need is an angle position sensor, but it does not need to be very precision, so I don't need an expensive encoder. I potentiometer is good enough.
Hi, There ARE servos that communicate with a digital protocol including position (Not "digital" servos with the regular pulsewidth control..)
Do you just need position info, Or servo motor with position feedback?
I don't really need a motor. I need to turn an object either with a motor or by hand.
Can you tell me more about the servos you mentioned?

You can read the voltage off of the servo pot wiper, but you would need to open the servo and solder a wire and have an appropriate pot reference voltage.
