Tesla's Magnifying Transmitter "Replications"

[mr.clean]

Thanks mr.clean



Yes, there are. But those aren't necessarily based on physical characteristics or appearance, the thing also has electrical characteristics. When you scale down the physical properties the electrical characteristics don't scale down by the same ratio, so the exact physical proportions have little meaning beyond the original design if you intend to make a smaller version. At Colorado Springs the extra coil was optimised on the basis of its inductive relationship with the secondary, which gave those results. If you scale it down physically then you will not have the same relationship and you won't get the same results I.E. not optimised and a different end frequency etc.

Ok I get ya, yes im going by the patent, other large builds and basic intuition,

I plan on making a vertical type mono polar TMT, slightly larger than the average table top TC, I guess about like yours.

also tho I plan to extend the Don Smith bipolar setup, and add Extra coils to each end, as Eric Dollard's picture from the 80's

im also quite convinced that Kapanadze's device is a TMT in bull-pup form

Thanks mr.clean

but I really think there are precise guidelines for the Extra coil

The Colorado Transformer can be scaled to the broadcast band. Important is that the inductance of the extra coil decrease with the square root of the increase in scaled frequency. Also any lumped capacity must also decrease with the square root of the increase in frequency.

A 15 meter coil at 45 Kc/sec is a .75 meter coil at 900 Kc/sec.

A 25 milliHenry coil at 45 Kc/sec is a 5.6 milliHenry coil at 900 Kc/sec.

A 432 picoFarad terminal capacitance is a 97 picoFarad capacitance at 900 Kc/sec.

45 over 900 is .05 and the square root of .05 is .22. Take it from there.

Technically, the extra coil "wave length" if you are referring to a wire length is mostly irrelevant. To begin with the geometry affects the propagation velocity, so the wavelength-frequency-speed of light relations are useless as they are and need to be compensated based on the velocity factor if you want to end up at the right frequency with a certain wire length.

From Colorado Springs Notes, coils alone:
Extra coil wire length = 790 metres
Luminal frequency (light speed limit) = 94.8 kc
Measured frequency = 116.3 kc

Secondary coil wire length = 801 metres
Luminal frequency = 93.5 kc
Measured frequency = 42.8 kc

Coils together: End frequency = supposedly approx 45 kc

Both coils have approx 1/4 wave conductor length but the frequencies are completely different, they are in no way both resonating at the same frequency despite the wire length. According to Eric in Colorado Springs the extra coil is acting as a simple series inductor and as such the wire length is mostly irrelevant, the important thing to its operation is a particular inductance in series with the secondary, with a particular end capacitance. If you want to scale it down that is, it will be no good simply scaling down wire lengths because you won't have a Colorado Springs scale model, the extra coil won't have the right inductance.

thanks man I appreciate it! but I really think there are precise guidelines for the Extra coil, and from the pic in Tesla's TMT patent, the Extra coil is energized thru resonant induction of the secondary, (re-grounded at high starting potential) and also obviously direct connected as a sort of basic series inductor choke.

I just feel the extra coil is perhaps a bit tricky, can we tap different positions to find peak resonance without dampening ? gonna be a long but worthwhile task

I love your work to date on this topic, and Farmhand really has some good stuff too

[dR-Green]

...in the meantime, anyone find any new results lately?

im going thru older posts now, but does anyone recall the wavelength Tesla said the Extra coil was?
3/4?

so 1/4 primary (establishing the full wave for secondary), then 3/4 of that for Extra coil?

Hi MM
I thought the work of Boris Bolotov, related to Zirconium and its role in overunity power generation might have some relevance here. There is reportedly transmutation and possibly other effects, which might tie in further with this thread's topic. See:

Respectfully,

Bob Smith ..... thank you for the info ... and sorry for late reply

Yes I have studied some of Erics work, but I have never seen him demonstrate a Magnifying Transmitter.

I was wondering if somebody could point me to some information on it ?

A video or paper or photo's anything ? Peter or anybody.

I'm very interested. I'll check lamare's page again. I'm not all that internet savvy so I may have missed it.

Thanks

Hi buddy, surely you have seen this by now... but i only saw it recently...

Eric Dollard's Magnifying Transmitter !!!! and circuit drawings (posted feb 2013)

i cant believe how much good info you all have posted here, my life goal right now is Realizing the TMT / LMD as seen in this vid.

As I said:








Tesla did not pick Colorado Springs at Random, using a dart on a USA map , I would not think that a man with the desire to bring man closer to nature, would do so

You want nature to let you play with her, well first you got to know her (sounds familiar )

Thanks Farmhand Craftsmanship vs obsession with details is debatable I suppose MDF is good to work with in this case, it's soft enough to make sanding mistakes not too much work etc and it looks pretty tidy in the end, no grain to complicate things and stuff like that. All the holes were lined up using pilot holes and 6mm nuts and bolts to make sure everything ended up in the right place, the rest wasn't really important. I took a few shortcuts, no grooves for the wire, and the spaces for the primary and secondary sized using identical length bits of dowels while glueing it all in place. The middle MDF ring serving the purpose of keeping it more stable and measuring the secondary height at the same time. Having a whole turn of wire pretty much in contact with the MDF at the bottom and the top of the winding might not be a good thing, but all these sort of "questionable" things were contemplated in advance and considered not to be worth the extra amount of work for such a small (test) coil.

Obsession with detail is a big part of craftsmanship I think. The real art is in
the timing, as in choosing what to obsess over more and what less. It does
depend a lot on personal goals as you say. I'm finding that soon after building
my big coil I now want to rebuild it in a more practical way all pre-planned for
the improvements and tuning adjustments. But I don't like to disassemble
much, short on materials too. Good idea to build some small things too.

Anyway I'm no wind instrument expert but I think to make a sound there needs to be some compression at the input to focus/channel the air, and probably some vibrating thing which the air passes through at the mouthpiece (reed), with a resonating chamber. Maybe you could use a piece of paper or something like that to make the vibration. Sounds like it will be a bit of work to get it working though

Yeah I know what you mean, I did try to play it like a didgeridoo or a
trumpet, but the idea was the main sound would made by the arc at the top.
Mainly I wanted to just blow the gaps.

There's a few interesting differences between the different sized and geometry coils. The TMT is undoubtedly more efficient than how I've built the spirals in terms of output. But the TMT has quite a wide tuning range as a receiver, the 30cm spiral has much sharper tuning. With the TMT as transmitter connecting to the (earthed) radiator and 30cm spiral receiver I can quite easily light a 12v 1.1w LED array, but it won't work when I make the spiral the transmitter and the TMT the receiver in the same configuration. For that to work I need to use the 50cm spiral as transmitter. And then there seems to be obvious differences between the frequencies - I can touch the 50cm spiral output with one hand and light fluoros in the other hand, the bigger/higher wattage the better it seems. But I can't do this with the higher frequency TMT or the 30cm spiral, only the 50cm spiral will do this. However the TMT will light an incandescent bulb brighter than the 50cm spiral will so clearly this is a frequency related phenomenon in my opinion. I believe the TMT is slightly higher voltage at the grounded end than the spiral is so I don't think it's the (lower) voltage of the spiral that's making the fluoro light when I'm in series with the coil output.

Yes interesting, that does make sense Maybe it's time for me to build a spiral,
I want to build one that I can stand on it's side or put on the wall and that is
the one I should make to suit my local radio station frequency for listening to
the radio

Bag pipe didn't work , blowing air into the pipe so two air streams blows the
gaps seems to blow them out too easily then the safety gaps fire. I haven't tried
a vacuum yet.

dR that is a really nice little build, your a bit of a craftsman. your
woodworking is much better than mine. Well done.

Cheers

I think in the first two videos the extra coil isn't physically connected, but testing this configuration from Colorado Springs Notes in the last one

[dR-Green]

This is my latest creation, a small "test coil" using Eric Dollard's calculations for 3.67MHz, approx 1/72.4 scale. 2 turns 20.7cm primary, 20 turns same diameter secondary, 126 turns 8.28cm diameter extra coil. Built out of 6mm and 12mm MDF with 9mm hardwood dowels, no insulating work done on the frame at all. Had to use 26 SWG wire which presented problems in the secondary in the way of easily bending and the coil becoming a slight octagon resulting in about 15cm of wire left over. The extra coil wire length worked out perfectly, but the whole thing being so small it's impossible to space the wire evenly. Space has been left above and below the secondary allowing for primary coupling adjustment and condenser rings adjustment at the top. The extra coil is supported by a 20mm PVC conduit with a tight fit for adjustment, with provisions having been made for dowel legs/supports (the four small holes).
