OK, time for another update!

Swapped out the IRF540s for the IRF510s, still have an atrocious waveform even across a resistor, so I need to do some work on improving that.  It is quite possible that I am undervolting the UCC37322 drivers, and therefore enough current may not be going into the gates, causing slow switching.  I will definitely look further into this, as I am now quite convinced that clean, fast switching is an absolute must.  (I know Bob has been saying this all along; I just didn't quite get how fast--a 25ns pulse rise time with some hefty ringing on the pulse is NOT going to work here  ;))

I found reading about the Dave Lawton system quite interesting, including the bit about placing a light bulb on the output, tuning for the best light output, and watching the input power actually drop.  Sounds quite familiar, actually. :D  He did offer one more bit of information--when he looked really close with his scope, he found extremely short, extremely high voltage "kicks" when the MOSFET transistioned.  Furthermore, they were required to get the system to work properly--it was underunity without them.  Also, he has managed to close-loop a system this way (sound familiar again?  I think these are exactly the same technologies here, but Bob has a much better grasp on what is actually going on and how to extract lots of power!)

You can read more about Dave's system here just for grins:

Back to the bench... ;D

Hi Eldarion,

Thank you for the update!  Sometimes stepping back for a moment and then digging back in, can give one, fresh perspective.

I like the route you are on, and believe and hope that it will result in success!   ;D

@ All

Perseverance and persistence is what is required.  Especially for this project.  Bob Boyce has shared with us what he knows.  He explained that it had been over a decade since he had messed with the direct energy version of his Toroidal Power System.

I am convinced of a couple of things in these months on this project, and Bob's impeccable integrity is just one of them.  I have no reason to doubt a single word he has told us, either by writing or telephone.  I have said in private and all along, that if the system does not appear to first work, the fault is with either the controller (waveform, etc.) or the coil is wound improperly. 

That said, I would urge, in the strongest way possible, those reading this, to continue to see it through to the end.  Some have nearly finished their controllers, while others have set it aside for a brief moment.  Even Bob is tied up with that new hydroxy project he spoke about, not to mention battling continued illness on the family front.

So, press on in this new year, to success and be encouraged!   ;) :)


Warm regards to all replicators,


Bruce

Still working on getting it working; just thought I'd stop in with this thought: ;)

On a normal 3-primary Boyce coil, each primary is about 40 feet long.  The required potential shockwave should form if a pulse is applied to the primary whose rise and/or fall time is less than 40ns in length (a nonretarded light pulse will travel about 40ft in 40ns).  These rise/fall times are well within the limits of a conventional MOSFET driver IC with standard MOSFETs such as the IRF540Z.

With our six-primary coil, each primary winding is probably only 15 to 20 feet in length (I don't have the exact numbers here, just guesstimating from the dimensions of the coil).  Now we will need some serious circuitry to keep the rise and fall time under 15ns.  (I think I now have the means to do so, I will test it and post back here with the circuit if it works as it should--2ns rise time, 8ns fall time advertised; sounds good to me!)

This may or may not be a correct analysis, of course, but it seems to make sense to me.  Fits right in with stopping a pulse before it reaches the end of a wire, like Tesla mentioned. 

A main point here is don't do what I did and try to overlay the hydroxy controller, even a small part of it, onto the six-primary rotational technology--it won't (and indeed can't) work that way! ::)

More coming soon as always...

Hey Eldarion,

Great to hear that you are still plugging away. While I'm still getting settled back in at home (and reconnecting my lab), I have been distracted by the OC MPMM magnet motor that has been causing a lot of buzz lately. But this little motor has also rekindled my interest in the little magnet experiment that Marco did a while back. Remember Marco's dancing magnets video?

http://video.google.com/url?docid=5540717206741162529&esrc=sr1&ev=v&len=209&q=marcos%2Bdancing%2Bmagnets&srcurl=http%3A%2F%2Fvideo.google.com%2Fvideoplay%3Fdocid%3D5540717206741162529&vidurl=%2Fvideoplay%3Fdocid%3D5540717206741162529%26q%3Dmarcos%2Bdancing%2Bmagnets%26total%3D2%26start%3D0%26num%3D10%26so%3D0%26type%3Dsearch%26plindex%3D0&usg=AL29H21jDmJstvePyrlQS0-SdxBAYvHsuQ

I was just talking to Earl a couple of days ago about how I was interested in replicating it and he mentioned to me that Marco actually used some kind of bias on the little toroid that he was pulsing the magnets with! Later, I went through the forum reading the thread about his dancing magnets device and came across this from him:

"it seems to be a DC wave in nature and the coil did get a continous DC voltage and the pulses were added on top.

next i will try to cancel out one half of the sequence to see if i can end up with the phenomenon of induction."

Which also reminds me of what Sauron mentioned once before:

"if we have a powerful magnetic wave present @7.8 Hz and we make the coil cancel one half of the wave , the other half will "hit" the coil which can result in a vibrating "shock" effect and the output will be the other half wave , so basically a alternating half cycle which could look like a pulsed DC is some fashion."

Now this really has me thinking :).

God Bless,
Jason O

Hello all,

As some of you already know, I recently acquired a Tektronix 500MHz digital scope--this has allowed me to see an additional pulse generation problem with my FPGA-based controller.

For an unknown reason, it generates a perfect pulse sequence on each of the channels, but only for a certain number of cycles, with dead time in-between!!!  It looks like I have never actually fed the correct sequence to the coil, ever.  (This type of problem is nearly impossible to see without a digital storage oscilloscope with enough memory; hence the reason I never saw it before.  On an analog scope everything looks perfectly fine, even though it is not.)  Just to add to my befuddlement, the Verilog pulse gen code does not have any errors in it, so it must be Xilinx's synthesis tools acting up again.  I am not impressed with Xilinx's synthesis program in many areas; you can guess why! ;)

So it looks like another rewrite of the pulse generator is coming. :(  At least I know what the problem is, finally. ::)

Hey Eldarion,

Great to know that you figured out what's up now. I'm very excited to see how things will go for you once you input the correct frequencies!

Keep up the great work; we're all rooting for you!

God Bless,
Jason O

Hi Eldarion,

I hate to say it, but this is one case where bad news is good news!   :D 

Now that you have diagnosed the problem, perhaps the smell of sweet success is ahead...

No way to get those shock waves Bob described, without the correct pattern as everyone knows.  So this is very encouraging indeed.   ;D

Warm regards,
Bruce

Hope

This Bedini modded schematic should provide you with constant load matching WITHOUT oversaturation and be very effecient.  The youtube is just to show how well it does it's job.
