Yep I second that, welcome aboard helper.

btw otto I am getting some interesting things using Caduceus coils on a true mobious loop, it may amount to nothing but I will post my findings should it amount to anything significant.

So far I have got a 9.2 Mhz resonance of the coil from a 17Khz square wave source directly from my function generator. So I am tweaking it to see if I can get that 5Mhz sweet spot scalar wave. It may amount to nothing, but then again this may be possible.  If so then potentially it would only require one low voltage square wave source to get the multiple side band harmonics as well as the 5mhz carrier.

I have not tried this design before so there are a lot of unknown factors. Although interestingly the scope probe only has to be within about 10cm  of the device to pick up the square wave and spikes. No physical connection is required when using Caduceus coils. (which is something I have to be very careful of) Obviously with only two sections of 20 cross over  Caduceus coils the output at the moment is only about 300 millivolt (with mobius loop isolated from source signal) however I did notice that if you phase the square wave that either the upper or lower become dominate it is easy to flip the output +/- in this setup (the same seems to apply to lesser degree in standard coils) Which creates another interesting scenario. If the square wave is phased in this way at say 50 or 60 hz would it still be possible to generate an output? If so it will be directly AC. Without the need for an inverter.

Interestingly with a perfect balance on the Caduceus coils of the peak and trench square waves. On the power output of the function generator there is no load power from the collector loop, but as soon as I make on more dominant than the other, power starts to flow. If you have this on the scope you can actually see two of the peaks swap places around the a central peak

May amount to nothing, but was interesting to watch.

Hello all,

@13thHouR

If you have an idea then build a coil, test it, post your results......

Even the craziest idea can be a good idea!!!!

When I see that my power supply is starting to pump I also disconnect my scope and do the same as you: my scope probe is NEAR the coils but NOT connected. In this way I hope to safe my scope,ha,ha. My Tectronix is still waiting to be repaired.

By posting the details of your setup now you will get the benefit of experiences of many. In this work, every little helps. On the plus side you may bring some new insight to the table.

Hi Everyone,

@Helper,

Glad to have you on board with the project, the more hands working on this, the faster we will get results .

@Everyone,

I am currently working on a sophisticated control circuit (finally) based on a microcontroller and the AD9959 DDS chip This thing is awesome, check out the datasheet here:

http://www.analog.com/UploadedFiles/Data_Sheets/210775240AD9959_0.pdf

Now I'm trying to figure out how to make the part of the control unit that will monitor the voltage output from the collector coil. My thought is to setup an automated test setup that can sweep through various frequencies and record the voltage output. I would take the output from the collector coil, rectify it, and store that in a large capacitor with a resister on it. And then measure across the resistor to get the integrated voltage value.

Ideally, I would like to see if I can find an IC like a digital volt meter that could directly measure across the resistor and convert that into a binary value that my microcontroller can read (just like an A/D converter). The only difference is that this should be able to handle voltages up to 1000V just like a regular DVM. If anyone knows of any ICs that may be able to do this, that would be great.

The control circuit I am designing will drive the tube stage that I have been working on to find the three frequencies of conversion for my TPU.

God Bless,

Jason,

I would suggest a good RMS-DC converter chip, followed by a "dual-slope integrating A/D converter" chip that can interface to your processor.
