Is Lindsay?s ?SM? a fraud?

Hello all,

@Grumpy

what to say??

I hope I finally got what my friend in his PM wanted to say to me. I really didnt want to mislead people. The point is and was that nobody posted so I jumped out with my schematic.
Now, if allowed I want to wright down how I think he made it:

1. 2 or 3 MOSFETs with square waves from 2 or 3 oscillators, yes, I know about tubes but now Im talking about SS devices
2. the drains connected to a step up transformer
3. this step up transformer is pulsed

I did this with an oridinary 230V/12V little transformer. When I connected ma MOSFET to the 12V side I measured on the 230V side really big sine waves. Yes, I know that such a transformer is a s..t. Clear. I had to use much lower frequencies because of the core.....not to bother the people here.

4. such big signals are then feeded into the TPU. The point is that working in such a way is muuuuuch better than Im doing it because there is almost no current consuption from the power supply and the coils are cool.

5. after rotating and mixing the frequencies I use an output transformer to step down the big kilovolts swirling in my TPU so I can use this voltage.

So, in short, today I will try this. I want only to connect a little transformer to the drain of my MOSFET and see how and why.

@altium

OK.

the sm 17

the balums could be saturated as well as air core i think the effect would be the same  maybe not tho the saturated cores may be able to transmit more current or magnetic vibtations  i think there 2 freqs in it as there is iron wire and copper in the collector and you want to ring both and create a vibrating relay witch intrepus the curcuit  harvest the lil kicks right!!!

My question about the thickness was just to know the thickness of your ring and by stating 1/4" (6.25mm), it was to say "I hope it was not any more then that" because it would seem that any more then this and the core would not have been able to reach any kind of saturation point with the amount of windings used (60 turns of 24 awg). But now you are stating the SS core is only 1 mm thick. Now this is sooooooooooo thin. Probably why you notice less heat because this thin material is also acting like a heat sink. Are you sure about the thickness? One thing for sure, with 60 turns per quad over such a thin SS ring, such a core would be extremely reactive to any field and saturation times would be very quick and probably well in line with the higher operating frequencies you are using.

On your FG's, do you have adjustments for the Duty, DC offset and Amplitude and do you play with these as well as the frequencies themselves. It seems any time I touch the DC offset, I fry another IRF840. Can you explain a bit how you play with the FG controls. Also, are you using the TTL/CMOS output or the standard output. Do you use heat sinks on your IRF840s.

Maybe one last point I would like to clarify and that is when we say frequency as F1, F2 and/or F3, these are not real frequencies that one can consider as relevant to real frequencies and their additive harmonics. Going through the IRF840 these become fast pulsing on/off iterations. I will be preparing a post on pulse/frequency and the relationship to single point multiple pulsing as you are doing here because the involved complexity is not only dependant on the frequencies themselves but also each individual setting for duty, dc offset, and amplitude. That makes four variables per frequency and the dependencies between these makes this effort even more complex to replicate. Consider also that the amplitude is fixed at a set level and there is no sweeping action to simulate actual field growth and decay. What I mean is when I manually sweep the amplitude while pulsing, I am seeing more activity then when the amplitude is fixed.

OK, last last question. Are you actually using the wiring as shown in @altium's wiring diagram which basically shows 8 coils but set in 4 bucking coil arrangements.

I purchased a second FG of maximum 2mhz off of EBAY so I should have it soon..

Hello all,

@wattsup

I saw your post yesterday afternoon on my home PC but my PC is blocked so I cant answer you. On my home PC I can only read the messages and posts, nothing more. This happens only at overunity. com. All other sites are working great, my son can post on other forums....

My core is only a stainless steel plate 1 mm thick. Its a 316 grade stainless steel. This core gives me a bigger voltage and more power.

Yes Im working with frequencies in the range of 100 - 500kHz.

My FGs, 3 of them:

each has a ICL 8038 function generator. Output feeded into a jfet IC, the LF 357. This output feeded into a pair of transistors, DC 140, BC 141. This is the output of each FG. This is then feeded into a IRFP 450 MOSFET - Robertos great idea!! This MOSFETs are on little heatsinks. You almost cant blow them.

The duty cicle is 50 - 50 and I cant change this. And I think its OK so. So, Im playing only with frequencies.

Im using the setup as altium showed us but with 1 correction: the start point of the 1 load coil is connected to the +24V. In this way connected.....hmmmm....try it and dont even think to touch your TPU!!!! And dont connect the scope probe to your TPU!!

F1, F2, F3 means only that we use 3 frequencies, nothing more.

Hello all,

today I want to clarify something. I was at an Bulgarian site and I think people all over the world that are building TPUs have the same "problem". Im talking about the current from the power supply.

The people are calculating the input and output power when a bulb is connected to a TPU.

THIS IS WRONG!!!!

Dont do this!!! As my coils are NOT optimized my TPU needs 2, 3, 4, 5A to light a bulb. It doesnt matter how much!!!

Why?

The answer is easy: when I connect a bulb and have a good frequency mix, I SEE that the current from my power supply is CONSTANT!!! In some cases - very good frequency mixes - I saw, when a bulb is connected, the current DROPPS!!!!

This means that my coils are really not good because all the current from my power supply is needed to run the coils and NOT the load.

Everything clear??
