Power ratio over one

[hartiberlin]

Hi David,
many thanks for the new video.


But one can still not clearly see
how this see-saw rocker -electromagnet-magnet
setup works.
Where is the magnet exactly located that
pushes the see-saw up and down from the
electromagnets ?
Maybe you can show it with a macro-shoot
video ?
Many thanks.
P.S: How about just spinnging the axis with a small DC motor ?
Does this need more input power ?

Maybe you can also post the DC resistance of your electromagnets
and about how many turns of wire do they have or what kind
of brand this is and what kind of magnet sits nearby to push
the see-saw up and down ?
Many thanks.

I posted two more waveforms at ou_builders this time with the loads!
Using an analog multi meter:
The ohm readings on the driver coil (copper colored) doesn?t move off of 0.
The middle (green) coil is about 850 ohms.
The large end coil is about 1K ohms (the waveforms were done with this one.)

On the secondary unit, the coil shows about 850 ohms.

I  think I can answer this

I had to watch a couple  of times to  catch it myself.


The  first part of the  3rd  video   David is   moving the  teeter board showing the switches working

You can see  what looks kind of like a propeller  that moves  when he  moves the teeter  board.

That  propeller  is  connected to  the  main axle ......the   axle with the magnets  connected to it.

After  David  finishes  showing the  teeter board  switching     you can see him   turning  the propeller  horizontal .......then  the  camera  moves  and  you can then hear the  device  start running .

What is hard to see  when the  device is shown running  is  that the  propeller is  on top of the teeter board . 
It is an elegantly simple  way to be able to test them  separately  but   connect them  quickly and easly

It would be productive to visualize what is happening with the idea of "an imbalance of power".  If there were more facts presented I'd be willing to simulate it and I wouldn't mind if anyone would beat me to it.  I've thought for a long time the concept of "an imbalance of power" was very powerful.

Hi David,

Thank you for the details.  Isn't the near zero driver coil resistance suspicious for you?  A few (2-4 or so) Ohms of resistance should be there, right?  You can estimate it quite well by using the tablets in this link:
http://cs.nju.edu.cn/yangxc/dcc_teach/wire-resistance.html  or from this link:
http://www.epanorama.net/documents/wiring/wire_resistance.html 

If you find the value by some calculation from the tablets and  it is indeed near zero (0.2-1 Ohm or so), then there is no short circuit in your driver coil....   

By the way, have you tested one of your green coils in the place of the driver coil?  (for instance a green one whose shape and sizes approaches the best to the copper color coil)  This way the input power need would be much less than it is now with the very low (near zero) resistance copper color driver coil.  I understand that the coil resistance of a near ideal electromagnet is the lower the better (to minimize copper loss) but if you benefit from the much lower input power need by using much more number of turns than you have now, even at a cost of wasting more power in wires resistance, then it is worth trying to use the higher number of turns to get similar attracting forces.  Because you mentioned you get more favorable results when your battery is getting into the discharged state: this means your driver coil would still execute its see-saw task with 0.2-0.5V input DC voltage.  Putting this otherwise: your present driver coil is a bit overdriven, I think.  Your thoughts?

Thanks,  Gyula
