Paul, I just went back through my notes from the conference and I think you got it!
my notes do show P channel. So unless I wrote it down wrong you just solved my major hurdle. I don't have any P-channel so looks like I'll be a few weeks out.

Thank's
Les

With no other instruction, I just decided to start adding different air coils. I should have done this long ago. if anyone is still having problems getting more out of the 3GT or even just running a single coil off of the Bedini Cole switch on a monopole wheel - just start trying out different coils in parallel with the main power coil but away from the wheel, add a core, remove the core - it does not take long to get the hang of the tuning.

Les,
I have spent some time this morning reviewing the DVD series as well as searching this forum. please excuse my lameness, but I can not find where JB references 3+/- times per second.

My interest is in reading/listening to JB's actual words. Can anyone point me to the post or DVD - we have them all.

Our build seems to get more out of high amp pulse/low impedance and not so much about the freq. any time I increase the freq thereby lowering the amps in the pulse, charging suffers.

Thanks,
Patrick

IRFP260 is an N-channel, with the S-D diode. I believe that JB said to flip the S and D, so, at a minimum, that's wrong in the diagram. I also think that the diagram shows + and - backwards for U1 (compared to vid #28). I'll continue to to review...

I think that I "get" what the design intent is, regarding the dump on negative. The cap gets an ever-increasing voltage and gets hit by 300+V spikes. The circuitry "wants" a stable operating voltage and needs to be protected from the spikes. The circuit common, then, is chosen to be the cap -ve and the zeners provide a stable voltage +5 and +10 (+15) "above" the cap -ve, regardless of what's happening on the cap +ve side. When the circuit common reference is cap -ve, then the mosfets probably need to be referenced to cap -ve also (esp. S to G threshold voltage).

More pondering is in order...

Hi All,
For the last 3 weeks we have been testing a 2n4401 based Bedini Fig 33 SG self oscillator with a Conference Comparator Triggered cap pulser battery charger, running from 1.7V up to 12V or so. While charging 5ah 12V SLA. In the process of trying to get the Comparator circuitry's current draw as low as possible and still function correctly, I too found that current was flowing from the charging battery if the storage cap was not being charged, and suspected the internal mosfet diodes, so i tried a BD243C that does not have such diode, and it too let current flow
No part in place = No current flow

Hey Guys,

Happy New Years to everyone! I have been following the most recent activity, but don't have much to add. Other than really wanting to get this comparator circuit figured out.

As far as FETs, I would have to agree with Alex. IRFP260s are what I have in my notes/pictures from the conference.

**The thing that bothers me the most about this whole comparator circuit thing. This is not what we were shown at the 2010 Conference. We were told "one black wire in, one black wire out." And this was pretty clear on the pictures and at the conference. Supposedly easy to do with a FET and a Zener. Ha! Several discussions were had about this in previous posts. Now we are hot on the trail of this new circuit. What is right in front of me IS very confusing!!! It's confused in my head. Or at least that was what I was told by JB when I asked him about this at the 2011 Conference. What happened to the "one black wire in, one black wire out?"

Sure makes it hard to follow...


Thanks, Brent


@Patrick,

Here is a link to one place JB mentions dump frequency...post 155

Thanks Brent,
I think that's a good goal for all of you that are building to spec - 13 footers with the same cap and coils JB uses.
for us little guys with little wheels and smaller coils. I think we have to adjust expectations. I notice on the most recent DVD28 both wheels are dumping about 1/second which is about how often mine dumps using a 3300uf 350volt cap at 48volts.

Thanks again - shows how much I forget - saw a show this week on a study that shows dementia setting in at 45 years old - time to get serious about doing cross word puzzles LOL :-)

In the video, JB said he uses the "reference voltage" (5.1 zener, also attached to U1) to drive the collector of the H11D1 (pin 5). Battery -ve is connected only to the drain(s) of the FET, not to the collector(s) of the NPN's. In fact, he doesn't draw in the extra darlington MPSA06.

At the moment, I can see how to put this circuit in a box using 3 wires, but not 2.

1. cap neg, 2. cap pos, 3. battery neg (assuming bat pos is connected to cap pos outside of the box).

Please don't let my frustration confuse you...


At the 2010 Conference = "one wire in, one wire out"
At the 2011 Conference = Comparator circuit


Not sure why it changed, but it confused me and I didn't get a very clear answer from JB.

Oh well, maybe at the 2012 Conference = Answers


Best Regards, Brent

Wow I was gone for a few days and wham lots of stuff! Just got caught up so sorry for not responding earlier. I don't have the video yet so I can't speak to that. I do have my notes from the conference and I tried to draw as precisely as I could. And I do have a Darlington drawn driving the fet. it shows the fet connected directly to the batt neg. However I made the choice of an MPSA06. The circuit posted was one that I had tested and I knew would work well enough to get started. I was shooting for the lowest power usage I could. after playing with this Darlington setup I could drop the current to the H11D1 led by adding a much higher resistance and still get the switching. I am wondering now if that might be part of the problem. I wonder if the H11D1 is not fully switching because R9 is to high? Anyway I hope we can get some real testing in so we don't get caught up in guessing. and just remember what John said about the rock hitting you in the eye.........

Way to go
Les

Hi Brent,
Good to hear from you again. I think I understand what you are talking about. but I am pretty sure John will never be able to discuss that original circuit.

I now think that this can be done with one wire in one out.

I began reviewing this thread from near-beginning, hit nvisser's post #185 page 7 and it triggered an (as yet untested) idea.

In LK/RC's diagram (and the video), the power and reference voltages are taken from the cap pos.

Instead, unhook D1 and R4 from cap pos and hook them to bat neg (and readjust the ref voltage).

Now, the whole circuit runs from one wire "in" (bat neg) and one wire "out" (cap neg).

Bat neg "rides" 12-16V (depending on SOC) below the voltage at cap pos. E.g. when the cap is at +50V, bat neg is at 50V-12V = +38V. You just have to make sure that you leave enough headroom to power the op-amp (15V for 741, 10V for TLV3702IP, etc).

I'll play with this when I have time and report.

Q: Is there an advantage/importance to having only one wire in and one out?

pt

Paul,
I think you may have done it again....
this may take a minute to explain but this was what my testing resulted in today and I think it directly applies to the thought you just presented. I reduced the resistor R9 to 5.6 k. (by the way I have a LED between it and ground so I can see the pulses.). Now I was charging a little tractor battery and the voltage was 12.99 volts. I changed the resistor and after about an hour it was down to about 12.83 volts.

I got to thinking about this and realized what you had said about these changes. and I realized what might be happenning. My little test runner is only pulling a total of 370ma. So to run a full pulser circuit I am stealing far to much power to get any decent charging. I increased the resistor and charging got better. I think this is why the SCR circuit under these conditions is so much better. My test unit is marginal.

But here is a thought. The way mine is wired I think it might be stealing some power from the battery under charge. if so that's bad. We will make them batteries into Maracas..... Thus the value of your comment above.

One last thing I noticed in a comment from the conference that had to do with reaching the cap peak. My charge is a linear rise with no curvature. I am using 450volt caps and I think I should be using more like 50-75volt caps.

Anyway I think your right we need to get it running solely on the cap. So more testing is in order.
and Brent, thanks for bringing this up.
Les

Hey Les,

One other thing that you may try...

Based on the schematic that Ron posted back in post 1629, which he and I worked on together. You may try adjusting the capacitors C1 and C2. What I have found is that is where some of the biggest differences are found. I currently have 33uF for both of those. Seems to work pretty good.

Someone with a good scope will have to confirm this since the scope I have isn't very good. But what I can see visually is that the higher capacitance on C1 intensifies the brightness of the dump LED and seems to dump harder and the higher the capacitance of C2 the lower the main cap dumps in voltage. I guess it allows more time for the main cap to dump more!

Give it a try and let me know your thoughts.


Thanks, Brent


@pt,

Not sure of any benefit to the "one wire in, one wire out," merely an observation from the 2010 conference to the 2011 conference.

Good work on the circuits it seems that you have it down. You should be able to get your machine running. As for the box with two wires, one in and one out it's a fet opto hooked up to trigger on the pluses on the peak of the spike RS almost has it. I guess you could say the cap charges up and the Fet goes into breakdown and the current is delivered to the secondary batteries. That is why the secondary charges so fast. Comparator circuit should work fine but I would add a cap .47uf across the pins 2&3 of the 741 might help. No need to have a power LED. Great Drawings, Good work

Hey John B,

Attached is the comparator circuit I was talking about. The one Ron Chase drew. Is it the same one you're talking about?

There's been a few different ones posted, just want to make sure we're on the same page.

John K,
Good talking to you today, don't give up that circuit is very close to mine just some minor things to do to it to gain more stability with the 741 as they can be fussy. I can't tell where the components are but 741 is very noisy compared to ic's that we have now. .47 caps should be right on the pins. This circuit will work just fine. See if you can get the fets to work in the motor circuit in a quasi arrangement then you will not half to look for a P channel fet of high power.

John B,

I never give up, I just keep trying out new ideas. Some work better than others. I'll go research your last sentence. Will send you the results when I have them. It takes me a lot of time to test them out properly. You can't just test for 5 minutes and then call it good.

Great work with the Battery Load Box. A very elegant solution for the monitoring and charts too. Much easier than a PIC and more robust.


John K.

John B,

I found a circuit that uses an NPN BJT to fire an N channel FET on the high side and a PNP BJT that fires another N channel FET on the low side. I think this might work in the way you suggested.

Been thinking what JB said about aircore for the generator part. The axial flux alternators are great for low rpm windmills as there is very little drag on startup. but as the rpms go up as is typical with all generators the drag increases. Thinking in terms of this as a G-field I have thought about using a stator much like an R/C outrunner 3 phase motor. But I think I would want to get a higher voltage and if possible DC spikes rather than dealing with current. Anyone got any ideas?

Les

I have tried several flux gating techniques, and they all result in the rotor accelerating when you apply an electrical load to the gen coils. Just think G-field or the Leedskalnin PMH and you got the perfect generator! US 7,109,671 B2 is the perfect example of a flux gating motor generator combination...its beautiful, and it works...and its in my opinion directly related to the topic under discussion, and if that weren't enough, the patent is one of John Bedini's patents!

One of the unique features of this particular design topology is the concept of two asymmetrical spikes....I highly recommend this patent as a source of inspiration!

Hi folks, Hi erfinder you said about bedinis patent, "One of the unique features of this particular design topology is the concept of two asymmetrical spikes....I highly recommend this patent as a source of inspiration!"

I have also heard from a little voice, that it may have anti-gravity properties also.

Hi SkyWatcher,

"A method is utilized to temporarily produce a much larger source of available external energy around an energized coil. Then the unique design features of this new motor provides a method and a mechanism that can immediately produce a second increase in that energy, concurrently as the energy flow is reversed. Therefore, the motor is capable of producing two asymmetrical back EMFs, one after the other, of the energy within a single coil, which dramatically increases the energy available and causes that available excess energy to then enter the circuit impulsively, being collected and utilized."

That is a quote direct from the patent. The question that should be asked, and maybe I missed it when someone did ask is how are the two asymmetrical spikes being generated? I'm going to go out on a limb and say that one spike is being generated by the drive circuit. How this other spike is generated is a secret known only by the inventor of the method.

I have preformed a few experiments in this direction and I have found a means for producing two additional "spike like" manifestations, the method has commonalities with the Kromrey and G-Field devices; namely flux gating.... Is flux gating an aspect of this patented device? I say spike like because what I'm seeing is not a true transient, it is a spike like phenomena which starts off with a wide base. The more abrupt the change the higher the potential of this spike like phenomena, similar to what we see with electronic switching where the faster the switch transitions, the higher the transient voltage...

With reference to Fig.1 of the aforementioned patent, it can be seen that the inventor of the concept incorporated the mechanism for flux gating....if the magnets in the rotor are replaced with iron slugs we have a flux gate system which is similar to the Kromrey, and with the permanent magnets left in place we have something similar to the G-field device.

At the end of the day, it must be said that we have been provided with tons of of insightful information, in the various documents and posts found online, videos, and other outlets. Various machines have been demonstrated, their operating principles broken down in layman's terms. I believe our main problem is that we aren't connecting the dots, we aren't seeing the big picture (if there even is one....I believe there is...) We aren't seeing how all these different machines are demonstrating the various aspects of a single machine. The referenced patent is in my opinion the official public record of the G-Field, or "completed and or perfected (balanced) monopole (Energizer)".

It is highly likely that I am way way way way off....but you know what...it doesn't matter...results always speak for themselves.

Regards

erfinder,
Yes that is a good question. Could it be a kick back of sorts. As I see it when
the magnetic field is induced into the core, (north lets say)---->
there should be another magnet field in front of it (north magnet)<-----,
would this cause "the or a" pole to swap? (If the fields are the same
strenght) Ring once, second ring free?

I had a Engineer from Sweden in my lab today, and I started up the
Mini BT3. It's been sitting for a while so I am using a power supply to run it.
I had a 22000uf 75v cap hooked to the dump and could only get it to dump
at low rpm's, at first. The interesting thing I was able to show was a very long
Positive and negitive spike with a ring after. I have my probe on 10X but
it was almost off the screen. Very Faint and because of the low rpm's the wave
is moving a lot and doesnt show up well on a photo.
At 36 v and 400 ma in and 40 plus volts on the Meter out , he was just scraching
his head for at least 30 min. All the time I had my finger slowing the rotor down.
When I let it spool up to higher rpms, It droped the 36v's to 24v's, and the
amps droped to 200 ma. I think he is still scraching..
I am still scraching my head, because I still don't have a clear picture of what
is happening.

BrentA929,
Yes I see you over at the Earth Lights all the time. Look I will open the box and show you what is in it. This is an easy one for this group as they are more advanced. I do not run that big motor much as it barley fits in my shop and the Chinese keep asking to buy it, but it's like a tooth of which I knocked out.
If you look at these DC solid state switches you will find that you can hook them up to self trigger in reverse breakdown. That is all it is, you guys should be able to figure that one out, that is why you only see two wires coming out of the box. The capacitor charges from the Bedini/Cole switch and then the fet breaks down. But if you really think about it a sidac hooked up to this solid state relay will also work. Just put your thinking caps on about what I just said.
John
