Confirmation of OU devices and claims

[AlienGrey]

An upfront sorry for the possible off topic and/or boring contents of the next post / video's.

I was trying to dive into this effect i had (see quote) which shows the led going on on the 3th satellite coil
when the 2th coil was ontop of it, NOT when it was close together to it.

I thought that it would be the coupling which could be stronger that way, so i did some tests with 2 of these coils.

First test is with my Spectrum Analyzer and Tracking Generator.
Feeding 1 coil with the TG (sweeping from 9KHz (minimum) to 400KHz (so the 193KHz resonance frequency in the middle)
and "listening" on the other coil with the SA.

The coupling between these 2 coils can be monitored that way.

Second test was a similar one, now using the FG on one coil (sweeping) and the scope on the both.
The screenshot below shows the overcoupled situation (yellow the driven coil, blue the receiving coil.)
Video here: https://www.youtube.com/watch?v=jI6JszIDG4Q


It seems that we both overcouple the coils in a similar way, so no or very little difference in coupling strength
when putting the both coils side by side or ontop of each other.

So why the led on the 3th coil in the quoted setup did light up only when the 2th coil was ontop is still unanswered to me.


Next i will try to follow Gyula's comment to see if the top coil receives more power because of its elevated position.

Itsu Hi this device your Researching and Developing there is another Don Smith
board built on a section of plywood off cut I have seen whilst surfing the net  for other 'stuff',
the board i saw also had a Neon Driver converter module on board capacitor and HV diodes
what i'm getting at here is wouldn't the main out put coil be driven by an impulse pre driver circuit timing like a bunch of caps ? With the inductance the pulse would most probably appear as a sine wave eventually.

yes I do Thanks (so es das leben)

Very interesting tests your are performing ITSU.
Now I look forward to a test where you insert the (sweeping) signal to the big coil (serial resonanse) and make signal detecting with the scope or else on the two Satellite coils besides or on top of each other. In the same way as before. Parallel and 10kOhm.
About the puzzling question about the LEDs:
Is that refering maybe to some LEDs voltage threshold level (knee) that you come just above when putting the coils on top of each other?

Hi Arne,
Yes, there can be differences between forwards voltage specs of LED bulbs even within the same batch,  this is one thing.

The other question is why the induced voltage in the bottom coil increases when he puts the other coil on top of it, both coils are in the outermost position.  A possible explanation can be the TX coil produces a stronger field at that hight for top coil and due to the mutual coupling between the top and bottom coils, induced energy can increase in the bottom coil.  This is a possible explanation.

I agree with your reasoning I have thought of the same.
