Tesla Patent 382282, and all related to his transformers/converters

[TheNOP]

@Room3327
i am not thinking or talking of feeding a mechanical rotary switch with an ac signal.
from what i red, you can create an ac signal with it.
would it be pure ac, i don't know.
to be sure one have to build the thing and scope it.
but for sure, the limits on how often it can go on and off is pretty high and can competition with most today transistors.
the only draw back i know is wearing of the parts.

are you planning to go giga Hz ?

i am keeping in mind those two things when i talk about the mechanical rotary switch :
SM clearly sayed "best seen with tubes".
Tesla seem to have experience to same phenomenas using only mechanical rotary switch and/or sparks gap.

i am not saying Tesla device won't work with transistors, i am pretty sure it will.
just that it might be trickyer to transform it in a SM tpu with transistors.

NOP,
      I guess my question would be why would we want to build mechanical switches into a device that has no mechanical or moving parts, just to have something to wear out?  It doesn't make sense, and if Tesla had today's electronics do you think he would have used mechanical means of speeding up this device?  I believe, the tube thing you mention is another of SM's analogy's, as I've said before he was explaining that like in a tube there is two things going on at once, filament voltage and current, and the signal being amplified.
What in this device would not be able to use transistors, this is an AUDIO FREQUENCY device, we have learned to deal with audio frequency very well in the last 30 years with solid state as any audio buff can tell you. Please lets not try to make this more difficult then it is.

PIX,
    I am currently building the circuit, it is designed on paper but I want to prove it out before I release it.  It won't be long, my audio amplifier chips just came in.  So far I have not been able to power up my Tesla converter ring, not untill I get the circuit built.

@all
I usualy are stuck on the Joule Thief forum, but someone posted a mention of the work you guys are doing here so I thought I might stick my nose in here and take a bo-peep. lol 

Actually, what you chaps are doing here could be applied to the Joule Thief, I have made a JT with a mumber of output coils, strange thing is, the leds go out when I short a 2 turn coil next to the larger secondary.
I thought at the time I had managed to see that there was a rotating magnetic field, but couldn't prove it, but by my experiment, I knew something was there.

Aside from my stuff above, is the work you people doing here able to produce a self exciting magnetic field?
If so that will be interresting.

Keep up the excellent work chaps
I am learning as you proceed

well done

Hello Room, I guess what the answer is, by replicating to the original, and getting it to work, you would then have a bench mark.

I once was on the Nathan Stubblefield forum, he had a device, wound bifilar, iron wire next to a copper wire.

Now, to replicate this device everyone had great difficulty, as no actual device was in existance.
If I had one I would have had it apart quick smart, then posted how many turns, crossectional wire area, type of insulation, dimensions length, width etc etc.
Somehow or other NS incorporated a vibrating telephone relay into it, but he could have been harnising the energy of the make and break pulses to drive his coil i sync with the earths magnetic fields.

sorry for the 2nd post all.

Electricme,
    I agree with you, It's always good to have a bench mark. In this case though we are only talking about the drive signal being done in a different way.  The input to this device is very well understood, we have been using 2 and 3 phase inputs to all sorts of devices for the last 100 years.  A 2 or 3 phase sine wave input to something is not at all unusual. Yes I could build a mechanical device to run this but knowing all the details to the input, do I have to.  First lets try something easier to build, cheaper and much more flexible, to produce two sine Waves 90 degrees apart. I'll post my schematic in rough form today, I have to scan it in. I was hoping to enter it in my schematic capture program first and have it real tidy for everyone.
