Hi Rich,

Marco  came across this effect after i mentioned about the 2 rings in all of sm setups, i think this is the key to this device operation.
Although I think he found this out purely by accident, it must have benn about 2 hours ago.

focus guys on the 2 ring arrangement with coils, i dont think there is much to sm's device....KISS
Steven might have come across this phenomenon by accident.

Awesome

marco,

first, GREAT WORK!!!!!!!

the waves we are seeing seem to remind me of the shots you did with your 7.4-7.8 tests awhile back.  what are the dimensions of your coils?  were they wound to possibly optimize the reception of the 7.4-7.8hz frequency?  maybe this doesn,t even matter to just see the spikes.  but it might help to optimize.

the article the starcruiser posted on tuning loop antenna's,  seems to infer that by wrapping the loop antenna (toroid) with additional windings in some places (control coil)  you could balance your loop antenna for even finer tuning.

just some thoughts. KEEP UP THE GOOD WORK!!!!

LOL

AAAAAAAAHHHHHHHHHHHHHHHH!

Holy crap! I've run out of 'Depends' geriatric diapers!

@Marco,
Don't change anything yet !!!!!!!!!!  Just move the toroids a little in distance from each other to and fro along the center axis.
See attached!

I can't wait to hear from Marco on the results of his next setup. I am going to try and duplicate his results using 2 coils. I will need to make another coil setup but this is exciting! I am thinking the coax collector coil might do the trick since this is what Otto was using on his setup when he got some real promising results also.

Still thinking the loop antenna theory holds some of the answers, diameter of the loop (apeture) to help tune the coil and sustain the reasonance. I think the next step might be to create a feedback loop to increase the signal strength.

Just my .02

Carl

@Marco

hi, 
you are right about the graphic.
if the coils are moved it makes diffrence.
marco

This is big and I gotta post this publically. Can you give more pictures? Is it better?

dave,

can you kinda walk us through this circuit?  i can't get it all on the screen and still see it. i guess i should've gotten the big screen. but, i am having trouble with being able to see it all together. printer went down late this afternoon.

thanks
sam

I am submitting this to recap the coil driver side. Strictly on the hardware side. No sims or theories,yet.
So far:
Dave used Bipolar transistors and no bypass diodes, bases driven by 4013 CMOS.
Marco used IRF840 Mosfets with internal bypass zeners. I assume you applied a signal generator?
giantkiller used  BUZ11 Mosfets with internal bypass zeners, gates driven by 74ls139. I have to add a stage of 74ls244 bus drivers.

Dave has dual,multi freq, unidirectional 90 phase shift clocking.
giantkiller has dual,multi freq, bidirectional 0,90,180,270 phase shift clocking.
marco has total manual control, if you are using a sig gen?

@dave
thanks for the schem.
@marco
thanks for the latest test results.

Now for the sims and theorists:
try to tabulate in bullet format what you have seen come thru this thread about:
the coil calcs, windings/turns, wire gauges, # of coils ( no arguing!), anything item you feel is pertainent (no stories or lengthy theories!)

Think! Lets start on the design guide now and we will be done later.
Remember, as others and all have stated,
there are 3 areas:
Self starting. This will be dealt with last, so don't waste up front time on this. No one person is going to get any glory for figuring this part out. It will fall into place.
field rotation by segments This can e dealt with 2nd.
Coil/antennae And this is the big one! Find the collector specs, then the other 2 coils specs. After this, the device can be driven by mathematical specs and controlled experimentation with either of the 3 controllers previously mentioned. Because if the collector coil ain't right, nothing is right. Anybody out there know antennae specs and math? We have gotten great submits so far. I don't have time to site search this till I get my next stage done.

At this point, I welcome all arguments.

For those of us that have built coils already, don't despair. You are actually sitting on either a test platform for further on processes or follow-on products. It's all good. You see my coil is a ferrite core with no control winding. It is wrong? No. I am testing out the effects of a higher voltage rotating magnetic field. But my system setup, and  Dave's and marco now enables us to replace the coil with what Marco has or what comes out of the next flury of coil threads.
For those who want to experiment: to start off you need a oscope and a signal generator.

many blessings be upon you and
thanks be to all.....
We need some cheerleaders! We already got the beer and chips!
