Thanks for the expansion on my rather terse note, Jose. I forget sometimes that not everyone knows of the various Interstellar Events, even space enthusiasts.AdamQuote from: Rodal on 03/26/2017 03:08 amAdam, by TVIW is referring to: https://tviw.us/ TENNESSEE VALLEY INTERSTELLAR WORKSHOPTVIW 2017October 4th – 2017Huntsville, ALDowntown Embassy Suiteslist of featured presentations here:https://tviw.us/featured-presentations/

I fabricated a loop EMI probe. Yes, I used a stick from the yard as rigid support. There is a 5cm diameter unshielded loop at the tip, then coax, then an 8Ghz DC block, and then a USB spectrum analyser, which you can see in my hand. It is very sensitive, and by using it I was able to sniff out the majority of the noise to the 12V power leads - especially when the main amp is sitting idle. I saw very little EMI coming from the main 4000 mAh LiPo 12V battery itself - or the individual components. I'm open to suggestions. I'm thinking I could try using shielded wire (possibly coax) for the main power leads and then use a few ferrites.

The noise can either be from the battery, or from the main amplifier.

How then do you propose to calculate anything practical. Surely this is no more than theory for its own sake....I said no such thing! In my model/theory, units of Coulombs and units of Newtons are invariant with transformation of the variable refractive index, K. Invariance wrt changes in a gravitational field is not the same as an "absolute" measuring scale. Measurements are still relative to what "we" define as K=1.

WarpTech, does this mean we are in agreement that charges are discrete and conserved?
As discussed in the past (and as far as my memory serves) Monomorphic will run dummy load tests to check(characterize) possible displacement of the pendulum when all systems are running.
I think this is an important test regarding the impact of any involved devices. The later results with the frustum should be compared against the results of this tests.
System schematic and simple wiring diagram.
I suggest the wiring diagram to be more realistic than abstract. Lorentz force is an important factor in the measurement. Your grounding drawing is too abstract to be useful for assessing the Lorentz force. Specifically, instead of using ground symbols, better treat the grounding leads the same way as the power feeding leads.
