gates

Can we use any off the shelf flip flop ics since we only need a flip flop now? I only have jk and d flip flop ics, not sr ones, though. I'll have to learn more about them.

I tried all of the other gate types, and the NAND gate provided the correct logic states for both the inputs and the output. I suppose with the addition of NOT gates, another compound gate might work ... like a NOR gate. I just stopped searching after I found the 'golden goose'.

Just picked up my UCC27322's from the post office, plus the 1uF and .1uf caps as specified in the app. notes. I plugged it into the board and it's a clean signal. It tracks the phase signal output perfectly. The phase output signal PW is 1.02usec to 1.03usec as is the UCC27322 gate driver. I'm not going to 'ping' anything without recovery plumbing.

Hi 7imix, I think I know what you mean there, good idea. I would prefer to get a very narrow pulse to start with but it's not easy, the way you outline or similar would be good. I would like to bae able to adjust the PW to regulate the input power though rather than just raise the frequency. But I will try that when I get a chance.


To all,
OK I set up to try some stuff and I noticed immediately that putting a choke on the input to the circuit and powering the toroid directly from the battery, has made the trace very stable and nice and pretty looking. No sign of flickering, it's dead still. Sweet. There is effectively no "extra" capacitance across the coil like this but there is still the 570uf on the board. 100uf for the chip power and 470 accross the recovery end of the circuit which is decoupled by a diode. This big coil probably has enough of it's own capacitance for a powerfull discharge.

I have to work again for a couple of days so not sure how much experimenting I can get done. Don't have time to try anything much till later, just thought I would have a quick look while putting my boots on.

I put a few winds and an LED around the input choke and noticed that when I remove power from the circuit the LED glows for a few seconds which tells me there is some power stored in the choke, of course. I didn't think it would be so much, i'll include it in my next video. The 470uf cap+ is connected to the choke but I don't see how it could discharge through a single wire.

Just another strange thing to think about I guess. Love it.

Cheers

Is there any plan to test sine wave?

I forgot that 925Hz refer to sine waveform.


Farmhand, about LED lit after power disconnection, do you plan to trigger a pulsating circuit too? Oscillating power of an oscillation circuit?

Yeah sucahyo, i'll make a list of things to try, so I don't forget anything again. I have to add a resistor to get down to 925Hz.

I actually put the led on the wrong choke. It doesn't light when the circuit is running only a quick flash at connection and lights for a few seconds on disconnection. I meant to put the LED on the recovery choke. Just to see of it lights, as an indicator light kinda thing but it could do what you say maybe many possible uses for that.

I'll make a list of things I want to cover next session.

Thanks for the reminder sucahyo.

Some interesting scope shots.

This one is three coils connected in series. 1-2-3-pause. Neat.
http://9xfdag.bay.livefilestore.com/...006.JPG?psid=1

These one's are strange, after adding the input choke and some fiddling around with it I see this.
One long pulse and one short pulse repeating. Even the amplitude of the bigger pulse is greater because it has more power I guess. This is ony pulsing one coil.

Still no sine wave yet sucahyo, Having trouble staying at 925 Hz too. Still trying.

Cheers

Here's what the secondary looks like.

Hi Farmhand,

How did you get the "pause" now? ... or was that one pulse going 'on' and the three coils going 'charge-charge-charge' then the pulse going 'off' for the balance of the pulse period?

Later

[Farmhand]

Hi Gmeast, Haha, yeah I think thats just the three coils in series slightly out of phase kind of thing. With some tuning they turn into one like normal, I think it also has to do with the "extra" capacitance that was done with the coil + going to the board, at certain frequencies. This thing can make some really wierd waveforms.

Can't wait to get your three phase setup going.

No real luck with the choke's tonight, i'll try the suggested uH value, tommorow night.

Cheers

Now that I read your post again, just like you say is how I did it, I think thats what happened anyway

... or was that one pulse going 'on' and the three coils going 'charge-charge-charge' then the pulse going 'off' for the balance of the pulse period?

[7imix]

I ran some tests with a dip packaged MOSFET driver. I protected it by putting a 10 volt varistor from battery positive to negative.

I was testing the same toroid that I fried my other driver with. It is a single coil toroid, no secondary. 24 gauge magnet wire with as many windings as fit on the toroid.

I tried both short pulses (with my inverter-AND setup) and 50% duty cycle, straight out of the clock into the driver. I was running at 20khz.

I tried without the coil as a control, and with the coil.

I tried with the resistor between the driver and the gate, and without.

I was running at 8 volts.

With the short pulses I got an interesting 30 volt oscillating wave (damping sine wave) that was slightly out of phase. Right now I don't have the right potentiometer to tune the clock frequency so I am just running at fixed frequency.

With 50% duty cycle I got sharp 110 volt spikes but no oscillation.

In all cases, the measured temperature of the driver chip was 85 degrees after both 5 minute and 20 minute tests. The resistor seemed to make no difference in the driver chip heat dissipation -- in fact the test runs without the resistor came out to 84 degrees instead of 85, but the temperature in the room also had dropped slightly by that point.

[Farmhand]

OK 7imix, good stuff, so that means we don't need a resistor or anything there.

I was thinking that the recommendation to use a resistor there in the app. note's, is maybe to suppress the spikes in the first place. Touchy conventional electronics may require that. Although a conventional circuit most likely would not have a coil being pulsed like that anyway.

I think it's time for me to order some componants.

Hi Farmhanc,

Check our blog.

@ all, I'm going to slow down a little to make some component tests before hardening up a preliminary, Rev.1 design. It has to do mostly with power consumption and similar overheads. Having been supplied with some additional information, a short PW pulse and NOTHING between the Gate Driver and the FET Gate must be the rule I'm told ... no diodes, resistors, capacitors, etc.

When I say slow down, it's only because I have to wait for parts to come. Power density with this particular self-charging technology relates directly to frequency, pauses in the pulse stream and that's most of it. I have found that most of those folks that had acquired or had been supplied with Hex Controllers have been met by disastrous consequences for their toroids and electronics when attempting the self-charging effect ... mostly because of a lack of full understanding as to what's really going on with LE and probably some careless errors too ... It's new technology to me I'll tell you that. So, I must design the controller to operate at lower frequencies initially ... just to get our feet wet. That requires testing a full-compliment of components ... and as I said above, I have to wait for that stuff, and some of that stuff includes a couple more of those solderless breadboards because I'm not willing to dismantle the present prototypes just to create more real estate.

Those parts will arrive by next Thursday. I know this isn't a race, but I'm very glad my Toroid is finally finished. That's the progress report.

Hi all,

I'm not sure if the Rosemary Ainslie MOSFET heating Circuit people have moved to a dedicated, controllable circuit ... (probably should not have if they did), but since I became aware of non-Hertzian (waves), I began to think about their heating circuit's output of COP>1, and what caused the effect. Initially, it was the 'runaway', self-oscillating, MOSFET that was 'blamed' for the effect. I hope they haven't moved away from that, because I believe that 'runaway' behavior generated a non-Hertzian output. I see they are trying to 'synthesize' a waveform. Mother nature might not like that, but time will tell.

Anyway, I thought I'd mention that I recognize a similarity in results between our efforts and the Ainslie thing.

That's it,

Rosemary Ainsly Circuit

Hi Greg, the rosmary Ainsly circuit is the first thing I thought of when I bumped my circuit into the 1.5 Mhz oscillation. I've seen some scope shots of the ainsly output and I can make my scope look like that kinda, the whole screen can be covered by lines very close together.

I don't know much about the Ainsly circuit, I didn't look into it much because it doesn't seem controllable, at least I still had some frequency control not much. The runaway mosfet thing is quite easy to do when you know how.

Basically to me ( I don't know a whole lot) the Ainsly circuit is a resonant tank circuit with the PWM to get it in oscillation and keep it there, the Mosfet is controlled by the circuit noise. Nothing special in my opinion.

Basically a complete loss of controll I think except for pulling the plug anyway.

Cheers

[Farmhand]

I just had a quick look at the Practical guide article. And seen a 145 Khz reference. Wow were they measuring the heat produced to get the cop. If so that doesn't impress me. It also uses possibly one of the most expensive Mosfets on the market, so that it can handle the abuse. I'm not overly impressed by it. How does one use the heat produced. The last thing i want is heat. Seems like it's just a demonstrator device to me, a battery charger with a very hot componant.

I didn't get much heat with mine all the power went into the charging battery.
And there was quite a bit of it. But my setup was not walk away from-able as it was prone to further runaway. Believe it or not, and so in my opinion I had way over cop 1 just from the output to the charging battery.

Where are the lab results from the Ainsly cop tests I wonder? And who tested it and was it verified by a third party ? The practical guide says it has not been replicated by others.

Seems strange that a cop 17 device is not more usefull thats a big gain if true, but if it's all heat it's not much use to anything.

Again it seems very strange that an open source circuit producing such a large gain is not replicated more.

I want only electrical output and will not be measuring unuseable heat for cop testing. I don't see the point to that.

Hi Farmhand,

I almost got VERY involved in that effort. What it's turned into is one circuit revision after another and NO results. NO ONE in any part of that thread has built a scientifically spec'd out calorimeter. People there for some dumb reason build their own versions of an inductive resistor thinking it will make a difference. You take a wire-wound power resistor about 250 - 1000 Watts ... the kind covered with ceramic ... motor braking resistors. You can get those 'surplus' for about $15.00 ... new about $60.00. Then you build a Class-1 calorimeter around peer review specs ... the kind you find in the papers published on Cold Fusion and all. Rosemary herself really isn't interested in replications of her idea ... yes it was 'theorized'.

Heat is useful if you're cold. Heat can be used as a source for some low-powered heat engines ... Sterling Cycle for example. Heat is useful in processing food and chemicals. Heat can induce cooling in some thermodynamic cycles. You light a propane fire in a propane refrigerator.

I may be wrong, but I think Rosemary is still looking for funding ... and I'm not sure if there have been any offers to independently test, or if any operational devices have ever been OFFERED for test ... I don't think so ... else there would be MAJOR headlines ... not just claims ... as was the opener for this technology.

Aaron tried to replicate, but couldn't get a 555 circuit below 50% duty cycle??... we don't have any problems with fractional %'s.

That thing is a 'hype' topic ... career builder. It was only theory.

I mentioned before ... crackahcrackah ... he is attempting to duplicate Tesla's disruptive spark, multi-phase converter like in the patent and use the power real-time, but using solid state instead of commutator & spark for the disruptive-part. Don't know where he went with that. Bob made the distinction though between what we're doing and Tesla ... Tesla is EM ... we are LE. Can the two meet? We'll try and see.

I HATE WAITING FOR PARTS! They will probably NOT arrive when I thought because I forgot that TODAY is PRESIDENT'S DAY ... no USPS mail travel today probably, plus it's MY birthday too ... a double strike! Oh CR_ _OLA!

Happy birthday Greg.

.............................

Yes heat can be useful but electricity is even more usefull.

Last night I deviated from usual for some research on another project for the future, a "current pass pulser I will call it. Basically I want to build a solar setup that will pulse alternately from two caps that are filled by a radiant oscillator which draws power from say a 12v - 2 amp solar panel say 400 Ma for the oscillator the rest of the current which will fluctuate with the sun is passed through an inductor to the charge battery as Pure DC the 400 Ma should be easily attainable in low light.

The oscillator fills the pair of big caps, which are alternately dumped to the battery from whatever voltage is desired. I have the alternating dumper and oscillator almost worked out using only one IC chip, but I will need help to get it all together later. IT will take some trial and error aswell.

So basically when the sun comes up current will pass through the inductor, then when 12 or 13 volts is reached the oscillator will start to fill the caps and the caps will dump when the desired voltage is reached each cap is decoupled from the panel by some method when discharging ( I have a few idea's for decoupling) The cap dumping should be fairly low frequency 50% duty frequency controlled by the oscillator output.

It will take some tricky circuitry, but i think i can do it.

And I LOVE SOLAR.

Because the current would be fairly unrestricted to the battery no Power would be restricted. Alternating cap pulser ensure's no restriction to the oscillator output. A perfect setup. As long as you have a battery swapper so the batteries don't get overcharged.

Have a good one Greg Happy birthday again. I bet it is nice scenery in wyoming. I've never seen snow.

Cheers

I will need a low voltage cutout and voltage regulator for the circuitry.
