Bob Boyce TPU thread

Hi Bob,

I was wondering if you might be willing to offer some advice here:

I have a scrounged-up iron powder core that runs in the HF region just fine, as far as I can tell.
I have wound only a secondary (360? around the entire core) and three primaries--I have attached a picture below.

When I feed a pulse sequence of 25KHz, 50KHz, and 100KHz into each of the three primary windings, I get the output waveform shown in the attached scope shot.  The pulse width in this case was 250ns for all three frequencies.
The scope settings are: 5V/vertical division, 5us/horizontal division.

When I varied the phase, nothing really changed on the output waveform.  Is this normal?
Also, what does the output look like across a load resistor with a properly functioning device?  Am I even close?

Thank you (and thanks for the information on the OUPower.com board--it helped a lot!)

hello Jason and Bob

plan on uesing hi-temp quick dry Silicones 

to hold my wire in place  do you have objections?

will hold up to heavey vibration and hi temp.

Hi All,

I have updated Earl's corner, if you have any replies, please reply there instead of in this main thread.

@Bob B

Please take a look at my latest measurements and especially I would like your comments on my latest thought experiment.  Since my circuitry is now evolving towards quadrature phasing, this means a minimum of 4 coils.  Since I don't want to distract from the main 3-coil thread, I will be keeping my little corner separate from this main thread.  As soon as I find the time, I will update the thought experiment to show all four coils with phasing.

Here is a source for both the 20 guage, and 16 guage, solid silver plated wire with teflon insulation. Contact Steve at ApexJr surplus in California to see if he has what you need. Myself and some other replicators have had very good luck with buying this wire from Steve.

I hope this helps.

I?m back in Australia... and been doing more testing on toroidal ferrite cores, but first some comments on TPU testing and stability.

1.   For monitoring speed of light variations place a small crystal oscillator in the middle of the device. You can use this to monitor for any time dilation effects while tuning the devices. This could also be used for feedback control of external timing devices.


On reflection I will leave it at that. However I would suggest that people do a lot of basic testing of resonance modes with various windings before proceeding to wind a ?finished device?. I have started basic testing and have already encountered a number of interesting behaviours ? these are all with single ended drives. Right now the results are so varied and weird that I am still confused and will wait until it makes sense before commenting further.
I can tell you that when driving single ended that pulses offer no benefit over square and sine wave drive. Bob Boyce agrees on this point. This makes drive design much simpler.

Sigh ? great deliberations if I should say more or not at this stage... Longitudinal waves are the way to get interesting energy pumping effects. Transverse waves are just a waste of power. To a degree you want to maximize the amplitude of longitudinal energy to optimize energy pumping ? resonance of longitudinal modes achieves this. Biasing helps both in pushing things into collective behaviours and reducing excursions into unproductive signal regions.
