Stepper Motor Vs Servo

Hello all,

For my next project I am going to make a flea circus! I've already done a very small proof of concept which you can check out here
www.instructables.com/id/Make-Your-Own-Flea-Circus/

The EZb would be perfect for a project like this as I could talk to my fleas and have them perform tricks almost magically!

The biggest issue is servo noise and I wanted to know if anyone has done much with stepper motors and whether this might be an alternative?

If not, are there "quiet" servos available? (might be an oxymoron)

Thanks,

The three major solutions I have read on this Forum are....fill the servos with grease , quietening the gears. Wrap the actual servo container with automotive noise sealer material, and.... pure physical distance! Apparently metal gears are more quiet then plastic....... :) some food for thought

What a cool and fun project. I'd love to make one of these for the grand kids. I've always been fascinated with this kind of "slight of hand" sense I was a kid.

The only real sound quieting methods We've found are what irobot58 stated. I've used dynamat insulation with good success. I covered my servos with the stuff and found the noise was cut about in half. I bet if you also covered the inside of the box you would get even better results.

Thanks gents - much appreciated!

If you have a look at some you-tube clips on flea circus's, there are some pretty amazing ones out there. I love the idea that I would be able to just give commands to the fleas and they would perform.

Ah...., you do know that there are no real fleas, right?;)
