Complete information on working SM style device.

This is the problem, there is a lot of differing information on the NMR of Iron itself. the proton frequency of 400 on that site can be changed to reflect a lower value and hence a lower NMR for Fe.

Im still trying to find the exact frequency via other channels.

Some of you probably read this link, some probably didn?t. I read it a long time ago and a couple of days ago again. Something made me to rethink about the control coils. I don?t know who posted it but it is interesting to read, especially one?s thoughts about the control coils.

A graph on that link looks exactly like one posted by Feynman.

GO FISH!

Hi MeggerMan, Earl etc.

thanks to MeggerMan's posting of a digital logic circuit simulation here:
http://www.overunity.com/index.php/topic,2582.msg86713.html#msg86713
I finally managed to get a bit more familiar with the concept behind Earl's rat race circuit. (I had no idea about digital logic stuff)

I drew up the following, which seems to give roughly  the same signals as suggested by spherics in his first posting in this thread.

My question is:
Is this circuit (see illustration) technically sound and can I simply put four Mosfets in place of the four LEDs to control the 300 VDC - coming from a voltage doubler from AC mains signal - to pulse spheric's four coils X, Y, Z and A ?

I attach the source code of the simulation, which can be used here:

@Gustav,
300V, don't be so silly. Start off at 1V and work your way up.
You need to drive the mosfet with a mosfet driver like the UCC37324 or something with a very fast on/off time and able to handle about 4A or more. You also need some very fast mosfets too with a fast on/off time to avoid heating at the higher frequencies.
Picture here is a mosfet solder to a PCB heatsink and being pulsed at 1MHz. The IC on the board is the driver(not in use).


I use a 30V 3A variable voltage/current bench power supply so I can start low and work my way up.
You need to scope the output across the coil because your back EMF will most likely kill your mosfet if your pulse voltage is too high.
Like this:

I'm surprised that hardly anyone has built a test rig to try out Spherics idea yet.

I want to put together this circuit soon and give it a try.
