Attention Examiner users

[hung]

My EE wanted to ask how current can flow in a SHORT CIRCUIT.
As far as simple electronics,,,HOW SIMPLE CAN A SHORT BE.
.................................................. .....................................
HUNG MAYBE I GOT a BAD UNIT?????????
i LOOK AT THE UNIT CARL TOOK A PART AND IT LOOKS ALMOST LIKE THE ONE I GOT How can it work.can you post THE INSIDE OF YOUR UNIT.
i WANT TO GET THIS THING WORKING.

Hi Clondike, sorry for taking a while to answer. I was out in the field.

The Examiner delivers microvolts. If you walk fast past an object that you input the frequency on, the antenna will move a lot faster than if you stay in place waiting for it to point to the target.
I once emailed RT placing a coment on the aproach of increasing voltage and current on the device. They claimed they have done this in the past employing a 9v battery. Theyadded that allthough the pull increased, the accuracy was no good, so they chose to keep the design as it is.
I did not agree with this statement and moved on to add some extra electronics inside and a VU. It's ok. This was the basis on my much more complex LRL system project.

Although I cannot divulge what I changed in the examiner original circuit, I must say that the original version should work ok. If your unit is nof swinging to an object as you get past it, it sure should be deffective. As you might know, a lot of practice is required to avoid you own movement to interfere with the device's own one. My examiner is the diodes one but I already tried one from a teammate which is the inductor model. I haven't found much discernible difference, except that the diodes feel a little bit faster in response.

Please, if you want to discuss this with me, drop me your email in a private message, as this topic only matters to examiner users.

Regards.

I will play with this as you said and give it more time.

Well - I don't know whether to laugh or cry...

So the new ground-breaking LRL from Hung turns out to be nothing more than a modified RT Examiner. What a remarkable step forward in technology!
On a scale of 0 to 10 on the credibility meter, I would say that you are now nudging into the negative region. Be careful you don't bend the end-stop on the meter.

NO!!

Sorry if I misexpressed myself.

The mod I did to the examiner was just to get rid of the swivel system. I inserted extra stuff inside and a VU which shows activity when pointing to a target.
The project of the original examiner works, but in my view, requires a very skilled operator to not involve his own hand movements and thus leading to incorrect readings. I also found out a way to enhance the response of the original examiner without the need of employing batteries. This is the original topic of my thread above.

My LRL system has nothing to do with the examiner itself. When I said it ‘was the basis’ of my system, I meant that upon seing the mod I did working, I came to know that the principle was correct to a more compllex aproach which now we are materializing. It’s a complex electronic system/device. As an analogy, it’s like a pocket radio and radar. The principle is the same, but they are totally different animals.

Well I hope to have cleared things up now.

PS. Clondike, If you indeed find out that your unit has problems I suggest adressing this to RT directly and maybe getting an upgraded model?

I dont know how a radio receiver and a radar are similar.For me they are totally different technologies AND principles.

I thought this was interesting. It uses a calculator to provide a signal.

Maybe after Carl sees this he will consider a total revamp of his Examiner report. How about it, Carl? Nothing wrong with admitting you made a big mistake. It's a whole lot better than denial.

[joecoin]

So he's manipulating the volume with his thumb as he moves it back and forth.

We are not amused.

You cannot be serious!

The video either shows some interaction between the calculator and the AM radio caused by EMI or, as joecoin says, the guy is "... manipulating the volume with his thumb ...".

The Examiner RT, on the other hand, has no interaction between the calculator and the random collection of internal junk, and the device simply "works" by ideomotor response, because of the swivel handle.

Does anyone here have a small AM radio to hand? This would be a very simple experiment to try.

[Fred]

I have a curious mind, so i did try.
I get the sound from the calculator, but no interference from metallic objects.I tried with both strong and a weak stations, i didnt understood what the guy said about this.
Anyway he is obviously hiding (and using) his thumb for some reason,however i dont think only messing with the volume would be enought to get this sound...
It is possible that by mixing the calculator oscillator circuit with one of the local oscillators inside the radio he is making a BFO detector.In that case working or not would depend of the radio and calculator circuits.

I'm sure Carl remembers Ranger saying the calculator had to be in the exact position. The point is the calculator does do something. That report has a few holes in it like a sieve.

Hey Mike, thanks for the video link.

Ithe calculator had to be in the exact position. The point is the calculator does do something. That report has a few holes in it like a sieve.

Yes the calculator is the function/frequency generator, although the examiner circuit delivers only microvolts, it's sufficient for the purpose of this kind of concept, although with changes it can be increased.

You are correct again, the calculator's clock circuit has to be exactly over the antenna inductors, otherwise response will be sluggish. I tried positioning the calculator in different places in my unit and response was almost null except when placing the clock circuit (key pad portion) halfway over the box, exactly how it's supposed to come from factory.

I dont know why all the fuss about the role the calculator plays. Any layman can open the examiner circuit box, position the probes of a multimeter and see changes in reading when the antenna points to something or the frequency is input in the calculator. Also, if you get rid of the calculator and take it off, the examiner won't work. Believe me, I tried. Interestingly enough, several weeks ago, I traded emails with a long time dowser who also has an examiner. He enphatically said whatever it is, he is sure it's not dowsing at all.

I wonder if this experiment came from here -> http://www.amazon.co.uk/Sneakier-Use...6626844&sr=1-1

Well, that settles it then.

If a dowser says that the Examiner does not function by dowsing ... then it must be true.

Can you specify what part of my report is in error?
