Servo help

If you didn't like the motor, you're really not going to like the RC servo. What motor did you use? Was it a gearmotor? Those typically are much quieter than RC servos.

An RC servo is a poor choice for this application. The controllers aren't really set up for this. They do not have variable speed but rather, position control. The rotation of the knob on the controller controls position, not speed.


A gearmotor and DC motor controller would be a much better choice. Check out pololu.com and servocity.com for gearmotors and motor controllers. They are not silent, but not bad.

Here is a video of a gearmotor with a shotgun microphone aimed at the motor at a 5' distance. There's plenty of noise that may be masking the motor, but you can't hear it at all. http://www.youtube.com/watch?v=LhaY-Lrbfa4

Even indoors, this motor is likely quiet enough that it would not be a problem for most applications.

These controllers are very flexible, easy to set up. http://www.pololu.com/catalog/category/95

This is the DC motor i got. I am going to use it for timelapse work because with my PWM turned all the way down it should work pretty damn well for that. The motor at full speed however is pretty loud I got an extra light timing belt, gears, driveshafts, and bearings from mcmaster carr. It all feels pretty solid so far. Tomorrow i will be doing the major building. I will be sure to post details as i go.

Those gear motors would easily work with my pwm. I just need to figure out what speed to get i think.
 
If you want something strong , smooth and really quiet, go with a stepper motor and belt. the noise servos make, or gearmotors, are the gears, the motor itself is almost silent, but as it spins gears at 5000 rpm, it starts getting loud.
