Magnetic Resonance Devices based on Don Smith Concepts

I will watch the film again, but the impression i got when i watched was he run the numbers through his computer, but dont remember him saying he simulated it, this could mean he chucked all the coil formula into a program entered how much power he wanted out and it designed coil dimensions and caps ect.

What i'm trying to say is there's 2 ways to sim a transfomer, you either use spice or you use pure maths of Vs/Vp= Ip/Is = Ns/Np ect

the latter he could use a zx spectrum LOL

I now understand how he closes the loop and powers a load at the same time.

The 2 coil inductor after the secondary caps is used as a 1:1 air transformer.

He is using a pulsed load probably much like the inverter on the diagram that Yucca is building with the 2 transistors, which draws pulsed current from the secondary caps, in the positive line from the secondary caps and his pulsed inverter load is the inductor which has the pulsed load current flowing through it, this induces a fluctuating RF magnetic field which is then coupled to the second coil on that inductor which is then rectified smoothed and fed back to the 12 volt gelcel.

So the whole circuit is recharging while powering the main load, the more power that is drawn from the main load the more power is put back into the gelcell to drive the primary inverter and neon transformer.

I am going to guess that 1 of the coils on that final inductor slides closer to the primary to adjust the coupling and hence recharge power that feeds back to the gelcell.

This is very clever and is probably in place of the matching resisitor he uses in Yucca's build diagram which matches the final output inverter, but a resistor is lost energy to heat, but using this inductor instead of waste heat we get useful recharge current instead.

Finished my secondary coil build now.

Specs so far

Wire 16SWG

Outer Diameter = 8.2 cm

20 Turn Coil Length = 13.5 cm

full 40 Turn Length with 3 turn gap in middle = 28 cm

Wire length on each 20 Turn Coil including tails = 528.5 cm

Once my meter arrives i can give L

Hi Peter,

Very nice coils!

May I ask if you have already dipped them with your GDO?  I am just curious...

Hi gyulasun

No i have not yet had a chance to do this.
I am not sure how accurate my GDO is and don't have a freq meter to confirm this, but when i did a dip on a small coil i connected my scope to one side of the dip meter coil and got a totally different freq on my scope than the GDO was reading, but this may have been because the scope loaded the coil i suspect, and i realize now i shouldnt have monitored the GDO this way, as i am new to using the GDO i need to get a bit more familar with it.

I am also worried that there are signs of it having been opened up in the past for what ever reason.

Another thing i notice when using the GDO is that the meter does move lower by itself when i move the tuning dial from min freq to max freq when sweeping, so it appears i need to keep adjusting the meter to read 0.8 as per the instruction manual, i am not sure if this is normal.


As soon as i get some time on the bench i will try different things to verify what the GDO shows.
