Complete information on working SM style device.

So, "Plan B" is screw the NMR and sweep with whatever you have - there will be a harmonic in there somewhere...

Yes, that seems reasonable.

The oscillator would need to be very stable with fine tuning but then we've always known that.

The "NMR of iron" may have just been to get you in the right freq range and not literal.  I would not expect arbitrary-dimensioned coils in different devices to utilize the same frequency - even in this case.  If so, the freq would be important enough to list directly, which it wasn't - so it isn't.

Yesterday I found a software package which will allow you to calculate the magnetic field strength/magnetic field lines of a solenoid. This should allow you to calculate the NMR frequency for your coil set and thus get you closer to where you need to be pulsing.

Very intersting read. Although I only read about 1/2 of the posts in this thread and the others concerning TPU's.

Is there anything that sums up everything that has been tested and built so I don't spend weeks reading through 50 pages of posts? If not thats fine, I'll just start from the begining and build one of my own.

Also what is the basic theory behind a TPU? I know the concept, spherics explained a new concept but not really any basic theory down to component level.

Just so someone doesn't assume, I am not a newbie at this, although I am also not an expert. i am going to college for electrical engineering technology and have two years left for my bachelors, after that I am getting my masters and phd.

Concerning spherics post - it almost sounds like hes made one and it works and hes just seeing if we have the ability/determination to figure out what he has.
