not finished

Greg, when we are going to see some diagrams of that thing to be
able to replicate it too ?

I just finished my super charger "bingo" (the name is given in honor of
stingo), and i am just going to publish it in new thread to allow people
to just sit and make it, and enjoy in its benefits right away...

I studied JT thread a lot last days and i took the best of what i found there
and using stingo making experience in the same time, i succeeded to make and test this stuff , and the results are very good, and now i offer people the result of my hard work...

So it happened in the same time, Greg did something and i did
something...

But, Greg, even if your project is not finished i would like to try to
replicate it, could you attach here your diagram or we have to wait
a little bit more ?

Congratulations and

I am in NO WAY finished. The results of this effort has given me inspiration to clean up the circuit hardware, get a toroid, get a faster Op-Amp, get a faster MOSFET and proceed to make one that REALLY charges as a single-battery circuit. This is absolutely the 'Holy Grail". This is the kind of device that will be the most convincing to even the most skeptical of the detractors.

I'm going to play with this for a while. I'll know better after letting it run all night with temperature changes, etc.

Wow, you have to do a lot more,before we could play with the fruits of your dids,
what to say, but cross the fingers, or better say, let God bless your efforts !

Cheers !

I'll post a diagram, but we may still need a good PWM ... mine will have limits, but I will try and get it going better with a faster Op-Amp. I also used the spare Op-Amp in the quad as a summing amplifier so I could offset the PWM to fire the FET properly. This meant I added another POT to control that Op-Amp.

Now, if someone will convince me that the 555 is better to use, then I'll go with that. But anyway, I'm making progress I think. I'm trying to keep the project as close to the original (video) circuit as possible ... less the micro because not everyone will be able to do the micro-thing, but all builders can do what I am doing.

One last thing I need to do is add a small choke between the Diode's Cathode and Battery + ... then I'll have all of the 'pieces'. Can someone tell me how to choose/design that 'recovery-side' choke? Please, what are the parameters for that component in this circuit? What does it do ... sideline the bad frequencies ... what?

Hi all, well I was able to get my setup down to 35Khz at 50 Ma with some good spike's so I connected the toroid I had wound with .7mm magnet wire and it was no good, the spikes measured at the diode went crazy to over 100v and fet got hot must have been too much choke





I think just a few winds of thick wire on the choke, I think i had too many winds. I have no idea how I should connect the recovery to the source battery.

No word back from my core enquiry yet probably wont get one.

Cheers

P.S. I almost forgot the main reason I made a post.

Good job Greg, awesome, I can wait till your ready, no hurry up from me i'll just mess around and experiment between battery conditioning, till I get some more componants.

[cikljamas]

I'll post a diagram, but we may still need a good PWM ...

Anxious to see it, i am itching to start the project !

Now, if someone will convince me that the 555 is better to use, then I'll go with that.

I recall one of your words about generally non relying on 555, i also do not rely
on 555 as good choice for such serious purpose as our goal is because i just do
not have good experiences with 555 in context of demanding stuffs...

I'm trying to keep the project as close to the original (video) circuit as possible ... less the micro because not everyone will be able to do the micro-thing, but all builders can do what I am doing.
,

Yeah, thanks for consideration !
It would be great advantage if you (we) made it without micro !

Please, what are the parameters for that component in this circuit? What does it do ... sideline the bad frequencies ... what?

I can not help you about that, but i recall how this choke looks like in our
video from the first post, half of toroid wound with that black wire, Watkykjy
i think said something about that too...
And Farmhand words are on that path too :

I think just a few winds of thick wire on the choke, I think i had too many winds. I have no idea how I should connect the recovery to the source battery.

Chokes

This is a diagram of the chokes that watkykjy1 made that i found somewhere. I Believe the two coming from the FWBR are on the same core, but not going to be needed for this application.

Hi pmazz850,

Thanks for your reply and the picture. I guess that leaves the T-130-45 Micrometals core wound to 29.7uH using solid, insulated copper 18ga wire. I take that to mean NOT magnet wire. As can be seen in the video(s), it's standard, insulated, single-strand 18ga wire ... ?

update:
Well, the battery is at 12.71V/12.72V this morning ... the highest it has gone so far. I think maybe this might be it as far as charging goes. I'll leave it all day. From a conventional 'charging' standpoint, I don't think this thing can deliver the 'stress' above this voltage to charge further, but then again 'pulse-charging' a battery isn't the conventional approach anyway.

So I guess from what I've seen in other posts that Micrometals has been inundated with requests for their cores and have stopped replying. They really do want to sell quantity wholesale ... that's what they are in business to do ... sell.

Thanks again. Later

This is where I bought my toroids from. Maybe you will have better luck going through them. They do have a minimum order though. might have to buy 2. Or you could buy some other supplies, winding tape, smaller toroid for choke,ect..

Hi pmazz850,

Thanks again. I didn't see the T650-66 at all ... or I could be blind.

To all ... a choke makes a difference here. It puts oscillations way above the battery with none going below ground (battery -) ... as far as I can tell.

It has charged to 12.75V. I took a smaller transformer and am using its secondary as the choke in the recovery circuit.

I now need to clean things up and get rid of the long skinny wires. I'm sure my circuit is quite 'squishy' at the moment ... I need big, short wires everywhere there is power and pulsing. The inductor wires will be what they need to be.

Anyway, I'm tired right now and just babbling. Talk tomorrow.

update

Hi all,

... couldn't help myself. I found and ordered a new Quad OP-AMP and a new Logic-Level Power MOSFET, both of which have 3 times the performance of the ones I'm using now. I'll get them Thursday/Friday or so.

Still at 12.75V/12.76V and drawing a constant 45mA. My Peak-Peak 'pulsing' voltage is at 13.97V last I looked. 13.97V - 12.75V = 1.22V differential. That's an appropriate stress for a charge, don't ya think? I disconnected the charge circuit and connected my 45mA-47mA load (255 Ohm x 1/2 watt resistor) and the battery did indeed discharge down to about 12.70V/12.71V in about 2 minutes. I disconnected the load resistor and the battery slowly recovered to 12.2V and settled there. I reconnected the charging circuit and the battery started its slow climb back up to 12.75V/12.76V ... where I hope it will either stay or climb beyond that over the next few days.

What's funny is: ... since I disconnect everything like the probes and meter while it's running, and only connect stuff to take a reading, I periodically feel the need to tap the probe on a lead and look at the scope just to make sure it's still actually operating (in the middle of the night too !) ... talk about mother hen obsession ... tee hee.

Anyway, later

Hi Greg, has the battery your using been charged right up to over 14.4 volts recently some other way, using a preconditioned battery might help.

Good work and congrats. Results can only get better.

I had a reply from the core supplier and they don't have them in stock but will order them for me and will sell me how ever many I want, even one if that's all I want, so a good idea is to look in the "contact us" section of the Micrometals webpage and then look in the "distributers" section, they are everywhere by the looks of it.

I'm going to go ahead and order a 650-66 and a 650-52 also some plain core's for desulfator inductors. Too cheesy.

Good work Greg, I hope your new parts net you even better results.

Cheers

You might consider posting what you're using so we all can look at the data sheets for those parts. There's a ceiling with these solid state parts unfortunately.

I would use capacitors in place of all batteries. They should give you an even better idea of what's happening with the effect. I never got around to using strictly capacitors due to school and my injury. Here's something else you can do to snag more output from your set up.

Wrap more coils around the inductor that you are pulsing and hook these coils up to a FWBR plus a smoothing capacitor, which then goes to your load. That radiant spike, from the vacuum, which occurs when the magnetic field collapses is big and you will pick it up in these additional coils. If you fill up that space around the inductor with coils you are tapping additional pressure that would otherwise not be tapped.

When I first had one of my batteries charging up I was waking up in the middle of the night to check the charge on it. It's exciting stuff. The internet has made it all possible.

And don't give up on that micrometals core.

Good work Greg, I hope your new parts net you even better results.

thanks ... I'm counting on the next batch of parts to give me 'real' results because I'm not entirely convinced that I have a very robust charge. I am glad to have used my present components as a training step.

I believe I already did but I'll do it again. I'm using the NJM2060_E-1 logic-level Power N-MOSFET and the tlc074 Dip 14 Quad Op-Amp for the PWM. I posted a picture of the transformer ... I can't read all of the printing on it ... it's old. Its primary measures about 8 Ohms. And yes ... none of what I am using even comes close to the requirements (speed) for doing this according to what I've read and viewed. I'm surprised I got any results at all with these components. In fact, I'm not entirely sure that I have 'breached the gap' yet but this is very close I hope.
.................................................. .............................

And "yes" it is exciting. It's very hard to leave it alone.

After my next 'swap', I will post a diagram and some more part specs.

I have every intention of acquiring the correct core materials ASAP, but $$$$ ... you know the routine.

Thank you guys .... later.

Battery

Hi all,

Well as any researcher knows (or should know) doubt and suspicion is actually a very good ally to make friends with.

Since I began this experiment (and thank you cikljamas for starting this thread), I have had certain doubts as can be seen my my first post here. All along the way I have several 'debunking' test to temper my excitement. I even suspected my battery was too discharged to use but I have always kept it healthy with a stupid $10 1Amp 12V/6V charger.

But today I decided to revisit the battery issue and check its specific gravity. I know that a hydrometer test is NOT a definitive test, but it is a good 'relative' test. Assuming the battery to be around 65 deg F to 70 deg F(which it is), a half charged battery will show as a low gravity and a full battery will have a higher gravity. So I reluctantly stuffed my hydrometer into my battery. Guess what? The float shot up "like a rocket" ! I have never had a battery with as high a gravity even after being charged on a high-end charger. I can't explain the lower voltage and a high gravity, but this battery is somehow 'charged' at 12.75VDC. There might be a 'known' explanation for this such as "it's become conditioned" or something, but the specific gravity is UP ... 'and so tangy too'.

Any insight into this would be appreciated.

Thought I's share. Later.

Wow, lots of great activity on this thread. Exciting.

I have been away from my lab, but I came across a very simple circuit which generates pulses directly. It's not an adjustable duty cycle rectangle wave circuit, it just generates an impulse wave. It uses a unijunction transistor, a capacitor, and a couple of resistors. I built it and found it easy to build and adjustable over a wide range of frequencies. When I plugged in the MOSFET and drove a wall wart transformer, I got some impressive spikes (a few volts more than the supply voltage) and the transformer oscillated nicely. I'll post a circuit diagram when I am back on a better Internet connection.

Glad for the information about mosfets in this thread, I have a whole bunch back at home that I look forward to testing. The MOSFET I am using now has a very gentle fall which is not giving me optimal results.
