One big ouch!
I am trying to find the first phase shift circuit posted here that used cmos flipflops? for a 90d output? Jason, Dave, Jacob? I followed right behind this with posting mine and I can't find it!

Thanks,

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

Guys, think simple, remember that, don't look too hard into it, remember nikola tesla didnt have what we have today, and i believe he probably stumbled across this too. I think i read that he was running with a power source that couldn't be explained, it may have been sitting in his pocket, look again and again at sm, first two vids and try to work around that arrangement.

2 rings and coils...2 rings and coils   focus

can't wait to experiment

goto go to work...Yuk

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!
