Guest guest Posted January 11, 2006 Report Share Posted January 11, 2006 Plasma tubes are fine above 10 KHz. I regularly run them well above 200 KHz. Some of the EMEM type devices which utilize plasma tubes are electrically incapable of outputting frequencies much above 10 KHz. Sine waves are fine if using the fundamental - or true MOR. Something to remember is that power is relative. For example suppose one outputs the exact MOR from an electrode pad device. A device that produces 15V at 40 ma. That works out to an application of 0.6 watts. That is 0.6 watts for the entire body. Suppose one uses a plasma tube device that outputs 300 watts PEP, but a subharmonic is used. If the sub harmonic is fairly close to the fundamental, there is going to be a lot more than 0.6 watts at the MOR being delivered to the body. People have discussed the ineffiency of Rife's machines, how maybe 50 watts or so out of many hundreds generated, were actually delivered to the tube. At the exact MOR, 50 watts is obviously an immense amount of power.

Guest guest Posted January 11, 2006 Report Share Posted January 11, 2006 I'll throw a whole new clinker into this discussion. RabbleRouser! The Plasma Tube is a non-linear switch; when not ionized it's a very high resistance load with some slight capacitance. When ionized and conducting, it's a low-value resistance, thus, the plasma tube itself converts any energy, sine wave or square, into a square wave, and the transition between the two (instants before it ionizes) lasts a few microseconds during which all kinds of RF chaos energy is released. I agree with Ian that a sine wave of exactly the right frequency is best, especially with a pad device, but when driving a plasma lamp, it may not make much difference. Thus I also agree with Medmidas. PS - the tube works fine above 10 Khz, its the driving source that has problems. Car ignition coils weren't made to run at that speed.

Guest guest Posted January 12, 2006 Report Share Posted January 12, 2006 , Keep this in mind: You are speaking of pushing an automotive ignition coil into a spark plug, an incredible load on the coil, the nearest thing to a dead short you can get is that tremendous 'fire' to ground of a spark plug. Next, you are dealing with incredible heat in the surrounding environment of an automobile engine. When we use this same coil to push a plasma tube in an office with a surrounding temp of say, 20C, [remember that a plasma tube is hardly any load at all] there is no comparison here. We have pushed auto ignition coils well above 25Khz in our early experiments. Yours, Dr. Ian MacLeod, Ph.D. tlaw@... wrote: OK Hot Rodders!! Let me throw this at you...

Guest guest Posted January 12, 2006 Report Share Posted January 12, 2006 Ken, A fat toroid coil with the right material would work. You can get a TV flyback transformer not the new ones but the old color TV ones that came apart. This type of coil with the electronics and windings to push-pull the primary can go 50 to 100 kHz or higher. PS: The whold hot rod thing was to illistrate just how far some are using a coil from the original design. >Hi Dave, > >What would be an alternative to car ignition coils so we could run >the frequencies higher? > >Regards, >Ken > > Re: Sine Wave / sq. wave > > > I'll throw a whole new clinker into this discussion.

Guest guest Posted January 12, 2006 Report Share Posted January 12, 2006 Hello Ian and others that seem to know how to get higher frequencies from an EM device, The coils used in the EM series devices seem to be limited to around 10 KHz. What where you doing to get 25 KHz from an ignition coil? Was the driver circuitry more sophisticated than what is being used in the EM machines? If so, in what way? Concerning flyback transformers - can they simply be substituted for the ignition coil? I'm guessing it is a bit more complicated than that.

Guest guest Posted January 12, 2006 Report Share Posted January 12, 2006 HI, In support of what Ian is saying here, for the very higher frequencies, you can also use a movable core / slug type setup. As the frequencies climb, as long as your switching transistor can go there, you can reduce the inductance by sliding the core out or using a different permeability for the desired frequency range. At some point, you can end up in the air core regime and into a Tesla coil, not set up for long sparks but instead taking the high voltage off the top load and into the plasma tube. Once you have reached that point, getting to 500 kHz or more is a snap (pardon the pun). We know the tube will fire at high frequencies, look at the R/B unit which has it firing at ~ 27 MHz.

Guest guest Posted January 12, 2006 Report Share Posted January 12, 2006 Thanks Ian, I don't mind paying a bit extra to get a transformer that is going to perform. I have seen some line output transformers (the fly back transformer) that has it's resonance peak at 30kHz, probably perform okay a bit higher, outputting 20kV. Around $30. I heard I need around 6 to 8kV to ignite plasma. I didn't know I could get transformers made to my own specifications, I'll have to look into this.

Guest guest Posted January 12, 2006 Report Share Posted January 12, 2006 Dear Ken, Not a problem, however know that you can ignite a plasma with as little as 500V - probably less - at lower frequencies. Generally, the higher the frequency, the more voltage is required. We have had a transformer wound for us that will operate in ranges from 0hz to 1.2Mhz. It is a dual coil, motile graphite / porcelain 'load' core. It also employs multiple taps for varying ranges. We keep it available for certain experiments, but nowadays we never, ever have to go beyond 12Khz in any protocol for the results we have enjoyed. Our coil was custom manufactured with our engineer guiding the transformer technician. It took days to manufacture and cost us nearly 3,000rmb which is about $US375. Shame, now that it is hardly used at all. We are now using a simple 50rmb ($US6.50) flyback transformer for all of our work. Funny how that works.

Guest guest Posted January 12, 2006 Report Share Posted January 12, 2006 Ken, A while back I looked into having a few high-voltage (6-10 KV), low frequency (300-500 Hz) transformers made for a research project. The quotes I received were all in the hundreds of dollars US. Perhaps the cost situation is better in Oz. I decided to try making my own transformers. Unfortunately there are not many books available that tell how to do so. A good book that is out of print so a bit hard to find is " Practical Transformer Design Handbook " by Lowdon. Warren Thanks Ian, I don't mind paying a bit extra to get a transformer that is going to perform.

Guest guest Posted January 12, 2006 Report Share Posted January 12, 2006 Hello , Be glad to throw you a good bone. First, depending on where you live, you can buy a Sony flyback transformer for any of their larger screen size [over 27 " ] screen colour televisions manufactured before 1997. Replacements in both OEM and generic are readily available. Install it as directly as you would your automotive ignition coil and stand back ... very effective with a teriffic frequency range exceedinig 25Mhz and maintaining a relatively clean waveform .... all things considered. These coils require a little distance be set between themselves and any groundable surface as they tend to allow side arciing when frequencies exceed 20Khz. Excellent choice. The only other option is to have a transformr winder put one together for you as we have done.

Guest guest Posted January 12, 2006 Report Share Posted January 12, 2006 Hi Ian, The 8 inch novelty plasma orbs I (and many others) are evaluating are manufactured in China. They use a fly back transformer. Gosh, you would have access to huge development resources there, and not be bothered by the FDA and AMA. No pharmaceuticals trying to run you out of town or close you down for helping people to be healthy. What complete idiots our governments are. There is absolutely no interest in research money going into RIFE technology, this might come back to haunt the western countries one day. The Chinese government took one of our directors to China about 15 years ago, doing some technical research into water resource management for their agriculture problems. They wanted us to move business there, and the deal was we would do very well, but had to keep all the business profits in China, we weren't allowed to transfer money back to Australia. China is soaking up western technology, and basically taking over world manufacturer. If the US doesn't get smart, soon, they will soon loose their position. I could well see China running with RIFE technology, making millions of plasma balls and flooding the world with this technology, which could really upset some pharmaceuticals. A change of global power could occur, if it hasn't happened already. This would be a lesson to the US, Australian and UK governments not to lie and mess with their own citizens. Time to drop the " war machine consciousness " which is old hat, and run with higher ideals, the ideals that the US and Australia use to adopt, but seems waning at the moment. Channel 10 (free to air TV), ran " in plane site " on national TV the other night. Now all my clients have this rage in them about the cover-ups of 9/11, especially when some of their children are over fighting a war that shouldn't have ever existed. One of my clients lost loved one's in the Bali Bombings, and they are now very angry with the Australian government, especially after seeing the TV show. The winds of change are surely blowing.

Guest guest Posted January 13, 2006 Report Share Posted January 13, 2006 Hi , I'd think twice about using a flyback transformer for a plasma tube used for direct contact. They contain a HV diode and therefore produce a high voltage DC pulse (not AC, as with all other transformers). Since an ignition coil produces high voltage AC (some of which goes through the glass, because the glass acts like a capacitor, when there is AC present) why would you want to use HVDC, which will not have this effect (when using the plasma tube in the contact mode? Before the 1980s (forget just what year) TVs did use flybacks which did not contain a HV diode, but these are probably rather hard to come by. Also, since TV flybacks are rated at 15kHz I would expect poor performance at low freqs. Bil PC 1000 M-Pulse 5000 magnetic pulse generator http://magpulser.com Mammoth Lakes, CA mailto:magpulser@...

Guest guest Posted January 14, 2006 Report Share Posted January 14, 2006 Hi, This will depend on the actual coil you use but here is a generic approach: Start by winding about 10 turns of #18 wire evenly spaced around the transformer's core. Place a 4 Ohm Resistor in series with one end of this 10-turn coil. Now you can use a power transistor such as a Darlington as an oscillator fed by your signal source. This will in turn pulse the primary winding of the flyback. Anytime I can help, Ian --------------------------------- Yahoo! Photos Got holiday prints?

Hmmm, winding your own primary gives you incredible control over sensitivity, waveform delivery, voltage delivery, and frequency response. Not bad huh? I have attached a photo of one of our 'modified' flybacks with the extra winding on top. It is currently delivering: 20v p.p. input ~ 41,000V Output 1.05hz - 35Khz operating range with optimal range 3hz - 28Khz. Sinusoidal Waveform passage deformity <8% Heat dissipation efficiency: 71% We run this thing for hours on end and its skin temperature never exceeds 40C. Actually, it never quite reaches that temperature for that matter. The resonator coil you see is a custom wound primary, as I am suggesting. The only difference is that we have put a motile iron/graphite core within the coil and use it to vary waveform acuity as well as HV Output. My hat off to our engineers ... and they said the Chinese aren't creative ... The primary on a flyback will only pulse if you tel it to .... hint. Keep in touch, Dr. Ian MacLeod, Ph.D. Lockard wrote: Hi Ian, A couple of questions if you don't mind. Of what use is the pulsing primary? What advantage is there to winding your own primary as opposed to using the primary that is already there? thanks, Dave --- Dr. Ian MacLeod, Ph.D., Liao Ning Research Group.
