Magnetic Resonance Devices based on Don Smith Concepts

Hi peter,

it was getting to maybe 50C, felt very warm but not hot, still comfortable to hold in the fingers.

Those big caps look like serious bits of kit, dont short them with a screwdriver it´d probably evaporate! I look forward to seeing if you can fill them at a fast rate, hope you can!

I´ve been playing with my rig a bit more, managed to get both primary and secondary oscillating at around 600kHz almost in tune. The transformer efficiency was reasonable, much less than 50% by my eye though. Interestingly I got most secondary power when I grounded the positive side of the bridge output (the node which 2 diodes point to) to my room radiator.

What I´d like to do is make a HV (20kV) cap module containing caps running in a power 2 series. so like 100pF 200pF 400pF 800pF 1600pF 3200pF 6400pF then also have a vacuum variable from 5 pf to 100pF. Using parallel combinations of these 8 caps can give any value of cap from 5pF all the way up to 12900pF at 1pF resolution or less. This is something I´d like to do but probably not for a while. It would be a nice bit of HV experimental kit though.

get some infra Red Goggles!

it will help you out a lot.

I look at these as an investment and if i ever needed to i guess i could resale them when i am done.

I like the idea of your cap bank, we may need something like this to find the value of the 2 mystery components in parallel, as well as tuning the primary and secondary coils.
What i am not yet sure is if he tuned 1 half of the secondary to the primary or the whole secondary, just seems strange he has the cap across one half in the device i am trying to build, i will try to do more ball park calcs today to see if it throws up some figures to work this out.

Are you in a position to move your primary coil realative to the secondary.

It's interesting the earth is making a difference.

keep up the good work, it sure is interesting.

So you will design your device for a voltage maximum in the secondary circuit of 10 kV?
As long as i dont misunderstand the primary circuit the lightning arrester will limit the voltage
on the primary side to 250-400 Volt,  so if you keep also a 1:10 winding ratio the caps you ordered
should suffice.

About the connection of the cap across only one half of the secondary coil.
It seems odd and might represent how little we understand of Smith`s thoughts.
It is very difficult for me to understand how the oscillation/resonance is actually supposed to happen
with a complex circuit like that hehe. Too bad it can´t be that easily simulated in spice :/

Hi xeno

When i did a search for oil filled caps on ebay several designs and ratings came up, it was possible to see the relationship between terminal size and working voltage as was expected, so using the ebay pictures as a guide i came to the conclusion there is no way that the metal can caps he uses are over 2kv working voltage, for instance there was a 4kv cap on ebay and it's terminals were huge and made of ceramic see attached picture.

So there is no way he had any higher than 2kv and i would say no more than 1000vdc on those caps, also in the diagram that Yucca has been building he goes on to connect the smoothed DC onto an inverter using 2 transistors driving another transformer to get back to 125vac, these transistors would never survive with 2kv on them.

There seems to be a lot of little discrepancies and i think we will need to work through these as best as we can, ofcourse i could series those 5 caps i have for much higher voltage so that is an option if we need to go down that route.

I found out that people use whats called grommet strips to hold coils winds together like that, not quiet as neat as the ones he uses but they will do the same job.

I have ordered some 14swg and 18swg tinned wire for now.

My Dip meter arrived today
