Hey Tk

Thanks for the vid.  Its interesting that the phase change happens. I had an inkling that it would. The reason being, I could not come up with any other change that might be happening between normal and SN modes.

So lets say if you have your Rx caps/light bulb on top of the coil, instead of the same a the Tx, where the caps are at the bottom, did you make up for that difference when hooking up the probe and gnd to the Rx? 

Like if we were looking through the loops from one end, if your probe gnd is on the left(bottom) at the Tx coil, did you have the probe gnd on the right(top) of the Rx, being that the orientation of where the probe connections are, are different?

Just checking. Maybe it is out of phase in normal mode, and in phase in SNM. 

Dont know if Im describing what I mean well enough.  ;]

Thanks for doing the vid. It is what I was wanting to see.  ;]  Perfect demo. 

The "maybe" it will go into SNM issue must be something in the Tx and/or Rx, like the caps possibly changing temp once in SNM and when it falls out, at peak current just before drop out, the temperature coefficient could be changing the cap value till cool down.  Also, if the caps in the Tx have opposite TC, it could affect each oppositely. So it may be possible if using the same brand, value and type of caps in the Tx and Rx, when they heat up, they would scale their values in the same directions when heating up and maybe avoiding dropouts as early and a more consistent lockup when going for SNM.  ;]

I also like the Zen aspect, I myself in my younger days studied Bruce Lee's book, Tao of Jeet Kune Do, it became my mental and physical bible and allowed me to progress to a point where the one thumb press up was no longer a dream. Be like water, my friend.



I had all his books when I was younger. I started boxing at 14 and used most all of his ideas for workout and what ever was legal in boxing. Bruce Lee Fighting Method series.
My trainers used to call me the cat. They always tried to take credit for my "fighting method", but I let them have their glory on that note. ;]

Hi TK,

Well done, you understood perfectly. The video you linked perfectly demonstrates the principles and structure involved (and almost the exact apparatus I am playing with), however, there should be two close tolerance tubes... one fixed and the other a linear oscillator. The ring is fixed to one tube, the cylinder fixed to the other. The magnets move in respect to each other, but fixed in relation to their respective tubes. So you glue each magnet to it's tube, is what I am trying to say and it is the tubes that move to transmit force and actuate, suitably greased to minimise friction of course.

Think about the finger that  pushes the cylinder magnet, it is storing force in the magnetic fields of both magnets in repulsion mode, until the distance = 0 and then the cylinder pops through the inside of the ring magnet and the vector sign flips. At this point you are going from maximum stored static potential to maximum dynamic acceleration as the magnets repel each other with a force exactly equal to what was stored.

The previous post covered the exploitation of potential difference between Hooke's Law and magnetism, both operating on the same axis... however I have since moved way beyond this basic principle. Look at this:

http://www.spudfiles.com/forums/i-gotz-a-35-bar-pushbutton-valve-t18317.html

Here they are discussing the balanced piston valve and one of the original designs from 2009. The key thing about this valve is that it is balanced, with equal gas pressure on both sides, the bias being provided by the compression spring which is weak enough to be pushed with a finger, or a less energy intensive voice coil linear actuator. ;) (No magnets in this design by the way, just a simple spring and balanced gas pressure).

However, I have been able to remove the compression spring completely, and Hooke's Law in the process, using gas pressure alone by filling from pilot side (use the search function!), and shifted the balance point from central to the extreme, storing that energy in the magnetic fields. So effectively, the same actuation force is required to actuate but you have almost the full power acting in a negative vector when it "pops", in addition to the positive pressure acting in the same direction = ?

I will cover it more fully in the actual post which will probably be over the weekend. In the meantime, if you have a moment to ponder, just think about moving the zero point to maximum offset... oh the irony...

Time for bed, night all.

P.S. Mags... Legal ? If it's got rules it's a sport...

P.P.S. Guns and engines work on the same principle, Repulsion of Mass from rapidly expanding mediums. People who study only one, or the other, understand neither.

Well, in boxing, you cant stop a jab with one hand, and follow with a back fist to the face. Also no kicking. Legal in boxing, is what I meant.

An electric koan: What is the brilliance of three bulbs shining?

The monastery is quiet; all the monks are studying and copying ancient manuscripts from an almost forgotten past. Tada Ima, a novice from the South, opens a crumbling text and out falls a strange diagram. He immediately takes it to his master, Jen Shin, who happens to have a PhD in electrical engineering, which he obtained before he attained Zen and opened his monastery. Master Jen looks at Tada's diagram, snatches it away and blows his nose on it, crumples it up and tosses it into the brazier. "Thank you, I needed a hanky".

Fortunately Tada Ima has a photographic memory and a lot of time on his hands.

Three identical 12-volt incandescent filament bulbs are wired into a simple circuit as shown. What does the voltmeter read? Are any of the bulbs lit, and if so, how brightly?

@evolvingape: I'm interested in your system...it sounds like you have applied the principle of the toggle switch in a non-contact manner, that could even penetrate physical barriers like walls and vacuum seals. This can be very useful technology as I'm sure you can imagine.
But... your comment about covering it more fully in the next post kind of scares me. Why not open a thread for discussion of your topic? I'd like to preserve a bit of focus here, at least until I'm done covering the basic prerequisites of knowledge that I believe some certain persons might be lacking, and that I believe would help immensely in the effort to achieve enlightenment about a certain circuit and its function.

In my previous reply to the bulbs A B and C, i for some reason thought the batts were in series. So I thought A and C were lit and B not.

But here, since I corrected myself, I see it is trickier. ;]   My first thought is, all 3 lit the same, but, if A and B are on equally, then B has 2 times the current flowing as compared to either A or C. So I might think that B is brighter and A n C are equal but dimmer.

A wise man keeps vigil for at least one of the four watches of the night.

Tada Ima was keeping his vigil on the midnight to two am shift, and he kept seeing the image of the ancient electric koan dancing before him. He realized that his memory wasn't really all that perfect, so he redrew the diagram yet again. Comparing the two versions, he became even more confused.  But at least he understood one thing: Master Jen had caught a bad cold, indeed.

Same setup, same questions. Three identical (very sturdy) 12 volt bulbs. What does the voltmeter read, are any of the bulbs lit and if so how brightly?

What determines current through a resistance?

The voltage across the resistance.  The way I see it, bulb B has the best chance at having the most current, so the voltage across B will be more than A n C.

Hi TK,

Yes I am playing with some interesting stuff, with a specific application in mind, and I am trying to make it simple and practical on a level that people can experiment with on the desktop, almost. Nearly there, bit further to go. Maybe even a video one day...

I do not see the barriers between disciplines that most adhere to, and sometimes I stray across those boundaries, please forgive me. I was not going to post anymore about this in this thread, was merely a taster for an alternative audience here, as I see the relevance. I understand you want to keep this on track and I agree. Ill shut up now.

Mags, I meant no offence, was just joking about Bruce's philosophy on the differences between sport and combat.

I learn more when I listen, so please continue.

I say the meter reads 24v (so far so good...). B is normally lit  :-\ and A and C have double voltage (24v) so are really shining bright?  8)
How did I do? Even close??   ???

Meter reads 0v.  ;]  I made the same mistake(tricky for some odd reason) that the batteries were in series. They are not.  maybe it is the meter presence that confuses what we think we see of the batteries and their polarity to each other.
