How many RPM on a rocker?

[Twmaster]

I just saw a YouTube video of a rocker engine running a tiny DC motor to power a small light bulb.

How many RPM does one of these little motors typically run at? I'd like to do something similar.

Thanks!

Hi Mike,
With mine it is totally dependent on air pressure supplied. I haven't measured it yet with a tach but I am guessing a range of between 1000 to 12,000 rpms with pressures of from 3-10 psi or so. Obviously with any load this would change. Can you post the link to the video?
