looking for a silent servo

for a small idea of mine i would need a servo which is able to move a weight of approx 500g and it should be as silent as somehow possible.
Is there anything like that arround for only a few bucks?

Never heard of it. Metal gear or higher quality servos may be quieter, most of the noise comes from cheap gears clacking together. Sweeping the servo slowly will also reduce noise. Google claims that some have packed the gear area with light grease, would load the motor a bit more but cut down on vibrations. Mount the motor with rubber grommets and surround it with foam, that should also cut down the noise.

sounds good… especially since it only needs to move quite slowly… hmmm

Could a stepper motor and a rubber band/pulley set up be used?
