Question:   When the teeter-todder beam is in resonance, does applying a load to this beam throw it out of resonance or does it just suck down the oscillations?

I'm having kind of a hard time figuring in a Q-factor with a mechanical device like this.  Seems there should be one and if there is, then your complete system should have a bandwidth just like any resonant circuit.  What this should translate to is if you can get a high Q-factor and find that narrow operating frequency, your device should literally tear itself apart--probably not really what you want.  If the Q-factor is lower, then there should be a fairly wide operating frequency where you can still maintain resonance.  That should also mean you can vary the load somewhat without ill effects on the oscillations/resonance.

Hi, when I add a load to the balance beam the length of the oscillation decreases and the rotating lever arms RPM increases. thanks for the help

working on large capacitor charge and discharge circuit using a manual PMA, there is a large amount of arcing at the contact when the cap bank is dumped to 12 volt charging battery. Searching for solution to stop arcing at the contact. Suggestions welcome

That's about as cool as I've seen in quite a long while.  It would be a real shame if this was a hoax--motor behind the wheel trick.

GoGrav, do you think you can mock something up with the materials you have around?  I'd like to see if there is any possibility this device has promise.  It almost looks too simple.  Definitely shows a new mechanism to get past the magnetic "stinking spot' that has plagued many builders.

Hi, I plan to give a try. Not sure if it is a hoax. It is using a counter weight but I am not sure where to place it. If it does work more then one could be added to the drive shaft. I will post result when available. If it works it would be nice to drive the manual PMA/cap dump super cap charger. Maybe use the spring counter balance, it looks like there is one in the video.

I am not sure if it is just one magnet being attracted to a iron flywheel or magnets mounted on the flywheel in repulsion mode with the magnet on the rocker arm ???

I've watched that video several more times and what I see I find disconcerting.  A true magnet motor will have a net positive force in the direction of rotation.  The key word here is force, also known as mass times acceleration.  Acceleration that will spin the motor into self destruction.  We don't see that at all here.  So either this video demonstration has some sort of speed brake connected where we can't see it or the video is faked.

This other video from New knoleg Invent is a pretty good clue since I know it is faked:

I even built the device and figured out the trick is a pulsing device within the supposed magnet base.  The pulsing device indeed has a battery.  It is necessary to have this pulsing device, otherwise the ball bearing will skid instead of roll and if the ball bearing doesn't roll, the wheel doesn't turn.

That's exactly what it looks like from 55 seconds to the end of the clip, when he stops the wheel to put in the pin.
Besides, we don't get to see what's behind the plate, why is that?
Because there's nothing to see there.........? :whistle:
