Here's some on ebay at present...
http://www.ebay.co.uk/bhp/gpo-relay
Youll need to ask what the resistances of the particular relays are, as its not listed on the auctions I looked at.
Its possible that the seller might be able to provide other relays of specific resistances if asked.

Thanks Sparks,

presently there are no relays mentioned with 5000Ohm resistance and/or the seller does not ship to The Netherlands :blink:

But i will keep a look out for them.

With Ebay, it always pays to ask the seller if they will ship to a country that isnt listed, as sometimes they will make an exception if you ask nicely. Also, the values of relay resistance I specifically wanted (5K and 10K)  I asked the seller about because he was only selling 1K relays. He had these values available, but hadnt listed them.
Always pays to be cheeky and ask for what you are looking for !!

Heres are some ebay sellers that are selling 5k relays and ship worldwide...
If you do an ebay search for "relay 5000 ohms" there are quite a few results.
Theyre not gpo 3000, but they could be disassembled for purpose.

Hi folks,

Well I am back...I have accumulated alot of stuff; I am in my basement finally and am pretty much setup to do this; but I tell you I am somewhat afraid...I been putting this off; but I play mmo pc games and play music like guitar; it seems to distract any emotion from interfering...and it also prevents me from continuing on.

I have been really getting these odd feelings of coils and electromagnetics...

I am sensing you were talking about 5k coils...well I am an electronics expert people...and I am back again to try this.

You can use audio transformers?? Or one side of them...altho they usually come on 1k on input and 8 ohm or so on the output; there may be 5k ohm input side audio transformers...

I have quite a few coils; I have some of Erland Babcock's stuff he gave me before he passed on as well and I need to get my act together and go thru this stuff.

I finally have a nice corner in the basement and privacy; but mind you I also play pc video games and the last month I was almost addicted to one; I QUIT the game it was consuming me; no woriies it was a space game but I do play army games as I was in the Air Force so I do have a military background...all in all the games help me I think and like everything we need to learn moderation and know when to quit.

I will be Live Streaming EVERYTHING from start to finish; if this stuff works people it works; and most of all when it does work if anyone, like me, get those feelings of fear and dont want to press on; we need that support.

I have setup a channel but I dont know how to save videos; I think I will have to pay $7 or so a month I dunno yet.

http://www.ustream.tv/channel/zeta-alien-technologies

This streaming location will be advertized in some of the better known circles; once I get movin on this, and figure out how to save the streams, it will be pretty kool.

I have one major issue...I am looking for Aliens not ghosts...but also, at this point I dont really care anymore what happens; I am to the point where it is time to get those results; the only thing is, when they really happen for me; I dont think the world is ready for it; maybe most of us in these circles already know that; most are skeptics; I am a skeptic which is a good thing as I am trying so desperately not ti cause emotional interference with the tests I do; and we all know how nearly impossible that is.

Well there is a secret and now I am being told to tell it....

Morse code; codes; ascii; ham radio codes; tty; languages like French or languages we dont fluently speak; we get those answers in a language that is impossible for us to duplicate; and we have SOLVED any interference problem.

Then I tought, tonite...why not morse code; I am pretty good with it; in fact morse code is readible thru noise where voice isnt; I dont know about computer generated tho even tho t is possibl; we may need it to read the code if it comes in too fast.

So yes; coils, magnets; this is the main areas I seem to be getting involved with...second are lasers and crystals (real rock crystals) and those things that spilt the visual spectrum I forget the name but there is a stone that is made to do that; I have some stone and sheets of it for scrying; this is spooky stuff; so that is where I am at.

Here is my website:

http://www.freewebs.com/mrzeta

I am glad to see people still here working on this.

I dont know when I will stream; I am working up a number of websites to let people know what I am going to do; setup my own website for some informationals; and just go for it.

I am usually on in the evening hours; if I start getting followers to watch; and see others streaming as well working on this; it will be pretty fascinating; let alone if results are obtained live.

Mr Zeta

Hi Mr Zeta,
In regards the specification of suitable coils, I think there is an important distinction to be made between winding resistance and working impedance. It seems likely that the use of 5k coils in the scole work refers to the coil winding resistance (dc), hence my earlier comments regarding possible use of 5k relay coils, etc.
The possible use of audio transformers, and their value is a different thing. Yes, there are audio transformers with 5k primary impedance, but the actual dc resistance of the winding is probably only about 300 ohms. I dont think therefore that an audio transformer would be suitable for the device in question, but I am very happy to be proven wrong.
regards,
Sparks.

Finally got my two 5000 Ohm coils and a piece of Germanium so i could put something together.

The output resistance i measure is between 2000 and 1700 Ohm depending on the pressure and placement of the screw.
This i feed to a 12v battery fed 800W MOSFET amplifier, but still i have to listen with my headset on as the output volume is every very low.

No real signals are heard unless i touch the screw with my fingers, then i hear lots of "mexican dogs" as mentioned in this webside (bottom):
http://www.glowbug.nl/projects/UM58.html

When i keep the signal as steady as possible and get zero beat i hear a local Dutch radio station as i can hear them speak Dutch.

So this thing works then as a crystal radio with me being the antenna.

I will try to get more output, but i guess i need a preamp.

Very nice build Itsu :)

I've not heard of the 'Mexican dogs' phenomenon before and will check that out.

What I can't check out now, is testing like that on my own TDC.
A gentlemen emailed and asked to buy it and while I fully support others being able to further their own research, decided to ship it for free.
It was found to be in a dismembered state as i'd repurposed the coils for a crystal radio build, so it was rebuilt.
Then was posted off a couple of weeks ago and the package included one of the solar radios as pictured above....which i'm delighted to read may be of use in understandings, following your reception Itsu of a station on the TDC.


Here's the rebuilt TDC, now with audio jack socket and using a germanium diode.
Hopefully the new owner will have success and post here.

On testing the TDC before sending, a rather clear piece of audio was picked up, via my usual method of using Audacity to record directly from the device.
My wife had just been in hospital for thyroid removal and we were discussing whether a spirit presence had been watching over her. The audio is of her name.

Wow, thats a clear piece of audio!!

Guess your "mediumistic faculties" are better then mine, see this thread on OUR:

http://www.overunityresearch.com/index.php?topic=2350.msg36533;topicseen#msg36533


I like the idea of a germanium diode, i have severall i could try, also i have peeled open a big old germanium power transistor.

However, there is no way to tune then, probably a magnet near the coils will vary the inductance somewhat.

Thanks, regards Itsu

Hi all,

I read about the TDC device several years ago, but when I saw the schematic diagram again in this thread, I suddenly had the impression that it could be a kind of a scalar wave receiver.

When Eamonn Mgherbi and Kevin Webster from England (NewWorldScience) came to our EVP association's convention in June this year, they presented to us a device and a theory for using scalar waves to communicate with spirit entities. Their design includes two opposing electro-magnets which create a "scalar bubble" between them, and a coil system in the center of the "scalar bubble" to receive the signal.

Some aspects of scalar waves are described in this article I found when I googled "scalar bubble".

With this theory in mind, I think it could be promising to modified the TDC device a little towards its function as a scalar wave receiver:

- The 2 coils should be directed towards each other instead of the parallel arrangement.

- The coils should be powered by DC so that 2 opposing magnetic fields are generated.

- A germanium diode is placed in the center between the 2 electro-magnets, where the magnetic field strength is zero, and where the supposed "scalar bubble" is.

- The Germanium diode is not connected in parallel to the coils. Instead, the received and demodulated output signal is amplified as in a crystal radio.

- Maybe the entire device should be shielded against external radio signals, so that only the effects of the supposed scalar waves is registered by the diode.

Attached is a quick draft of the proposed concept.

Perhaps I will try this when I've got some time.....

All the best,
Stefan

Hi Stefan, it's always good to read about your thoughts and experiments.
Didn't recognise you from your handle, but did when I saw your location :)

I have a lot of time for Thomas Bearden, many don't, but there's no sense in throwing the baby out with the bath water. Scalar waves especially.
That brings me to thinking about another few setups for such an experiment:
A single filar pair of pancake coils, with variable distance between them.
Or, a bifilar pancake coil.
Or, caduceus coils.
Apparently a caduceus will allow energy reception within a Faraday cage, which would point to the scalar abilities.

http://www.n-atlantis.com/caduceuscoil.htm

The scalar bubbles experiment is intriguing. I do hope you'll update with the results.

That's an unusual circuit in post #52. As far as conventional physics is concerned it probably shouldn't do anything, particularly in a DC field.

However, putting a P-N junction in a magnetic field may be interesting, although I doubt such an experiment has been overlooked in the history of semiconductors.

Nevertheless, to 'get something to happen', I suggest there should be a method of adjusting intensity of the field in which the P-N junction is placed, either by varying the current through both coils or adjusting the distance between the N-poles and the diode.

Are there any clues to intensity of the field in which the junction it placed?

Hi Janet,

yes, indeed, the circuit is looking rather unusual, but isn't the entire theory of csalar waves rather unusual? :)

From a DC point of view, the circuit is very similar to a crystal radio - with the only exception that the LC circuit and the antenna is missing. Instead of the antenna and the LC circuit, the diode itself is thougt to be acting as a receptor.

I didn't build and test this circuit; perhaps it has to be extended by a small bias voltage for the diode. In this case, the diode would generate random noise which is often a key element for ITC and other paranormal phenomena.

And yes, the intensity of the repelling magnetic fields could be made adjustable separately by varying the current, as well as the distance of both coils. Perhaps static magnets (neodyme) can be used instead of electromagnets.

In the linked article it's said that the more intensive the magnetic fields are, the larger the scalar bubble (or void) will get.

Stefan

Hi Slider,

very interesing article about caduceus coils. The Italian EVP researcher Dr. Carlos M. Trajna already wrote about caduceus coils in the 1980s. Very fascinating stuff...

Stefan

I've held a personal theory for some time regarding diodes and EVP.

The thought goes, that diodes do indeed carry the voices of the deceased. Small signal diodes are in pretty much everything for EVP experimentation. Only over the past few years have diodes become the same as SMD transistors, little black plastic pieces, rather than glass encapsulated silicon or germanium.

Diodes are mini solar panels...as are LED's and larger transistors if you take the metal can top off. I have 2x 1970's diodes of unknown type (from a Scanner/CB type of thing) that produce 6.5V @ 17uA when in series, next to a 23W CFL lightbulb.
One might wonder how the light can get in to traditional recorders, but even brand new digital recorders will likely have a front of the case LED !
Similar to diodes, a green LED can produce 2V and several 10's of microamps, able to run a blocking oscillator circuit in good sunlight. 

So, pretty much any piece of kit has an ability to allow frequencies in via a diode of some type and create it's own power, enough to influence recorded output.
An interesting aspect of DC and AC is that one type can ride over the other and remain separate...such as badly smoothed ripple from wall adapters. Such a situation could allow for a spirit voice to hop along a normally closed DC route within a circuit, similar to how high frequency energy travels over and not through a wire (induction wireless electricity).
If a voice from the deceased is thought of similarly to radio, i.e. it's a frequency, then rectification for recording can be managed by the diodes. Some of that energy may skip on past, which could conceivably give us the different classifications of EVP recording.
If there is a light component to the signal, bringing in recent full spectrum camera usage by some researchers, then the direct link to diode rectification of those frequencies can be imagined.

Hi again,

after looking a little closer at TAE's (Thomas Edison) drawings on film, it seems to me that the 2 coils should be connected antiparallel, not parallel. The arrows beside both coils A and B point into opposite directions, indicating the current of electric or magnetic flow. Moreover, wire 1 is connected to the front side of coil B and to the back side of coil C, and wire 2 is connected to the back side of coil B and to the front side of coil C. On the circuit diagram of the Germanium receptor device, however, it looks as if both coils were connected in parallel, so that electrical and magnetical flow have the same direction.

In the original article about the Germanium receptor, which was published in the 'Spiritual Scientist' Vol.2 No.2, there's written:

As you can see from the illustration, a void is formed where to the two fields oppose each other i.e. like poles repel (remember your physics at school). This 'void' has; been described to us as 'non spin energy space' and is not unknown in other extra dimensional concepts. It is in this void that the germanium is situated, right in the heart of the opposing fields (see fig. 4), where it can detect and absorb the fluctuations in the energies. These fluctuations cause this 'effect' on the germanium crystal to take place, opening the links with these far off dimensions.

My interpretation of this statement is that the important point is the location of a PN junction (Germanium in this case) right in the area between 2 opposing magnetic fields, where a "scalar bubble" is created (according to this article). The drawing of the magnetic field lines of the 2 coils in the TDC article show exactly this. However, in the circuit of the Germanium receptor, there's no battery or power supply connected to the coils, so no magnetic field is generated. So the circuit of the device doesn't match the description...

Just a thought: But why not using permanent magnets instead of coils?

The second point is the Germanium crystal:

It was during that session that an anonymous scientist (a spirit personality, communicating through the altered state) described in detail, a device that was to be constructed. This device would incorporate a piece of Germanium that was to be put under a small amount of pressure.

Semiconductor diodes were probably unknown to Thomas Alva Edison, but what is described here is exactly a Germanium diode:



The little square at the top is a piece of Germanium which is under a small amount of pressure by the little piece of wire. It's the same concept as the Germanium chip in fig. 4 of the article which is contacted by a screw with the end filed to a point.

Next, they talked about an amplifier with a high impedance input:

The spirit scientist also explained that some form of amplification would I be necessary, but expressed concern regarding our high mains voltage (250v). This was easily overcome with the help of Prof. Ellison offering to supply a battery-powered amplifier, with a high impedance input (one of the specified requirements). This amplifier was necessary to increase the audibility of the communications and was to be connected directly to the germanium device (the receptor).

Such a high-impedance amplifier can be easily built with a FET (see circuit diagram below).

The next quotes from the TDC article obviously refer to 'scalar waves' whithout mentioning this term explicitly:

One very important point was made clear to us, that the technology involved in these communications has no parallel in our world and therefore what we are describing here has no basis or 'model' in modern physics."

"The spirit scientist immediately added that electromagnetic waves (which include radio waves) are not involved in the reception of these communications. He told us all, not to fall into that trap as they are purely spiritual vibrations or waves that will be using the germanium as a point of entry or focus."

"This point, I think is worth emphasising, as it is so easy to think of these communications as forms of radio transmissions, which they are definitely not. Radio signals are received using a radio receiver, which is tuned to a particular frequency, or wavelength. The only electronic equipment used in this type of experiment, is the amplifier, this being coupled directly to the germanium receptor."

"Just to confuse things, remember that in this instance we are not actually referring to electromagnetic fields, but 'energy' fields or patterns. [...] So frequently used terms such as 'energy' and 'energy fields' are being used here to describe one of these 'alternative' concepts, only until such time as mankind has a fuller and deeper understanding of these matters. These 'energy' fields, associated with our coils, behave, we are told, in much the same way as their electromagnetic counterparts, with regard to direction of flow and polarity.


Another interesting technical detail from the article:

He [a communicator (not a scientist)] went on to describe to us (in a very simplified manner) the basic principles of the silicon chip, which uses a semi-conductor (silicon in this case but the theory is the same), and talked to us about something referred to as the'cut-off point. This cut-off point is very interesting, especially in relation to our other experiments.

As this cut-off point is reached, and as I understand it, this can be due to temperature/pressure (remember the germanium is under a certain amount of pressure), the semi-conductor becomes unstable. This instability is then followed by the 'cut-off, or in other words, shuts down. It is, he explained, this instability or fluctuation in direction that provides a 'point of entry'. This reminded us of the fluctuations in the 'energy fields' that cause the 'void' to be formed in the receptor. Perhaps there are 'doorways' involved here, if so, it would be a possible explanation for E.V.P. which many people report experiencing.


The 'cut-off point' of a diode is, simply put, the threshold voltage (at forward bias) between the conducting and the non-conducting state of the diode (actually it's a gradual transition, since diodes / semiconductors are nonlinear elements). For Germanium diodes, this 'cut-off point' is at 0.2 ... 0.3 volts. My idea is to apply a small (adjustable) forward bias voltage to the diode in order to reach this above mentioned point of unstability or increased sensitivity towards the 'energy fields' in the center of the scalar bubble.

Based on the above mentioned points, this is now my current draft of an updated TDC device:



The AC amplification of this circuit is about 50; if this should be too little, an additional OpAmp stage could be added.

I already ordered some 'super magnets'. :)

I'll keep you updated...

Stefan

Hi Stefan.

That's an interesting circuit - rather like the wide-band noise generators which use the noise generated by a zener diode, although yours is a forward-biased germanium diode in a magnetic field.

(I like the fact that you have paralleled the electrolytic decoupling capacitors with 0.1uF - folks often forget or ignore the limitations of electrolytic capacitors.)

Fingers crossed for an ITC breakthrough...

Janet

Yes, indeed, great concept.
Don't be sat in a rocking chair at 80 years old wondering about this one :biggrin:

EVPfan,


nice, i build that little circuit on a breadboard using the multi-turn pot like suggested by Jan.

Powered with a 12V battery i can hear some noises like some control or piloting signals via the grid??
When touching the germanium diode or the MOSFET drain i hear a local Dutch radio station, so shielding the whole circuit is a must.
Turning the pot does not change much in the audio.
I will try to put the circuit in a shielded box and operate it far away from the grid as it picks up lots of transients.

Video here: https://www.youtube.com/watch?v=tlehw5vLHeE&feature=youtu.be

Any luck yourselve?

Hi Itsu,

From the video I expect the hum is from unscreened wires feeding hi-Z inputs, both the BF256 FET and the audio amp - but I guess you know that.

Incidentally, I've had problems with FETs which were caused by different pin configurations to those that were published. Sometimes it depends on the manufacturer!

I'm curious to know what's causing the occasional high-pitched interference. Do you have any switched-mode power supplies nearby on standby? Or any data-though-the-mains equipment?

When I've had similar hum problems as a last resort I've switched off the workshop mains!

I like the magnets retained by tape as they try to repel each other - very simple but clever.

Thanks for posting the video.

Jan

Wow, so much response to my post, which I didn't see as I didn't get a notification e-mail for new responses...

Itsu, thanks for showing the video and for trying out my concept. I think the signal is coming from the mains power - some sort of control signals modulated on the 50 Hz mains frequency.

Well, I've been busy this weekend, and this is the current construction of my version of the 'Germanium Receptor':



The diode is situated in the center between two strong Neodymium magnets (diameter 20 mm, length 10 mm, grade N40, force 11 kg).

The north poles of both magnets are facing each other, hoping this will create a 'scalar bubble' to provide a 'gate into other dimensions'...

The magnets are fixed by adjustable wooden brackets, so different forces and sizes of magnets can be tested. (Electrical tape would be too weak to hold them apart. :))

The diode is connected to a high-impedance amplifier which I built on a breadboard:



Since my original draft of a high-impedance amplifier was far too sensitive towards the 50 Hz mains hum, I switched to a different type of amplifier with symmetrical inputs (a so-called instrumentation amplifier):



By adjusting the "Balance" pot, the hum can be cancelled out.

My initial attempts with a forward-biases diode were unsuccessful; only a very faint hiss was heard - no difference to a piece of wire, so it was just the internal noise of the amplifier. Therefore I now operate the diode forward-biased via 2 x 1M resistors. The resulting audio signal is a constant hiss and crackle. Within this noise, voice-like sounds can be heard sometimes. Here's a sample of my first attempt last night (slightly filtered with Audition):

20140817_0100_mono_nr.mp3

I hope my spirit people will become accustomed to this new technology soon... :)

Stefan

Hi Janet,

yes, the circuit is very similar to a noise generator. Some years ago I built one as a random source for my software 'EVPmaker', however it used the PN junction of a transistor, not a zener diode (see article). But shortly after I finished this device, I upgraded my computer which didn't have a parallel printer port, so I couldn't use the RNG anymore. Later I used this same noise generator circuit as part of one of the 14 modules of my other ITC device (see post & article).

Stefan

Ah, the TL074 - probably what I would have used!

9V through 2 M ohms only gives 4.5 uA. Is this enough? Could you reduce them to say 1k each (as current limiters) with 100k ganged variable resistors to see if there's a 'sweet spot' for any effect?

And very nice piece of construction to hold the magnets.

I can hear 'voice-like' noises in your recording, but I can't tell if they are just digital artefacts, pareidolia, or both. Perhaps forum members with more imagination than me could interpret something...?

Good work.

Jan

PS: I've just looked at your other links and construction. Beautifully assembled - I wish I had the talent for such neat construction.

Hi Jan,

thanks for your kind comments on my construction. :) - Well, I had several TL074 and TL084 in my organizer box, so I chose the TL074 for its lower noise level (haha).

The diode is supplied with +/- 9V = 18V (actually +/- 8.5V = 17V), so the current should be 9 µA (probably less since the diode itself has a certain resistance; I didn't yet measure the exact voltage at the diode).

If you look at the reverse characteristics of a Ge diode (see the below excerpt from the 1N60 datasheet), you can see that the typical current at 17V is about 15 µA, so even reducing the resistors to 0 wouldn't change much. However, the noise signal would be much lower due to the worse impedance matching.

But this gives me an idea: perhaps I should build a voltage multiplier (100-150V should be enough to reach the reverse breakdown voltage), and try to find the 'sweet spot' by varying the reverse bias voltage... :)

The voice-like noises were already audible in the original recording, only quiter, so they can't be digital artefacts. I'm not sure where these sounds come from, but in computer-generated white noise or in the noise from silicon semiconductors, I never heard such sounds...

Fantastic developments all !

Itsu, great video....could the diode being open to the light be allowing mains hum from your bench lights to enter the diode ?
Recent experiments have been with 60Hz harvesting and it wouldn't surprise me in the least to find that problem as part of the cause.
The radio effects could turn useful in one embodiment, creating a Franks Box type of hybrid device.

Stefan, great progress...

Most intriguing !

Jan,

i shut down the workshop power yesterday (one switch) and the sound was still there.
Only after removing the ground/minus lead of the Fluke multimeter it was gone (or not audible anymore).

As i have just above my head a 6000W (24 panels) solar system i suspect it is comming from there, or at least from the solar inverter and picked up by this minus lead.


Stefan, very nice build, those magnets are going nowhere:biggrin:

Regards itsu

Hello All,

I agree...great brainstorming effort.

Stefan;  I like the clean look of your projects.  My own breadboard attempts remind me of Frankenstein.

I listened to the audio that Stefan posted and isolated a response(?) that I found from approx. 26 to 29 seconds into the clip.

Can't say for sure if it is in German or not.

Here it is.  I looped the segment 3 times:

This evening I've built a voltage multiplier on the breadboard:



(No circuit this time - perhaps later...)

I thought that 4 stages would last to generate 100 volts, but even with 8 stages (16 diodes + 16 capacitors) only 84 volts are generated. Perhaps the capacitors are to small? (They are 100 nF.) -- I've got to look deeper into this later...

Anyway, the 84 volts are fed via a 1M pot and 2 x 470k resistors to the Ge diode. By the pot, the reverse bias voltage of the Ge diode can be varied between 0 and 45.5 volts. Not yet enough to reach the reverse breakdown, but nevertheless with interesting results.

I made a short (2 minutes) recording while asking for contact (adressing Friedrich Jürgenson). In the recording (and also during the live recording) I heard again these voice-like sounds, but this time a little lounder. However, I couldn't understand what was said.

Here's the original (unprocessed) recording: 20140819_0100_mono.mp3

I'm sure there is something... :)

(The 6 kHz tone is the clock frequency from the voltage multiplier. - I've got to filter it out better. Next time.)

Have to go to sleep now... (it's almost 3am)...

Stefan

EVPfan,

trying to keep up with you, but i am still at this first opamp circuit using a TL084 instead, powered from 2 12V batteries (so +12v and -12V).
Nice hissing sound from the earplug / MOSFET amplifier, but nothing else.
There is 15V directly across the diode 1n34 (25V total across the 2 resistors (1M each) and the diode).

At least the radio stations are gone (also the pilot/control like signal), so there could be no mistake there.

Short video here: https://www.youtube.com/watch?v=KBxut4Kts5Y&feature=youtu.be

Hi Itsu,

good work. Regarding your question at the end (2:40) of your video: I don't want to apply the 120 volts to the center tap of the 1M pot, but to the diode itself:



I also gave up the idea of using a voltage multiplier - this causes too much noise (the annoying 6 kHz tone). Instead I will cojnstruct a very simple power supply for 0...120 volts (some mA) output:



Stefan

Thanks Stefan, i see it now.


I will first do some testing with my 5000 Ohm coils (see earlier in this thread) instead of the permanent magnets.

question for the group: did this originate from the Scole Experiment?

I am a little behind, just found this link here, haven't read Robin's latest book, can someone tell me if details were ever actually specified or given, or were they left generic?

Hello,

Very kool to see this kind of work...I remember my post and read the info on the coils...I am currently working on cleaning organizing repairing all that good stuff and planning once again to seriously get back into low level signal work.

As you may know I am now live streaming most of my ongoing work - dont really look for ghost pictures in the streams its alot of time consuming work to trudge thru video frames...at some point I will be doing the actual research once I get standards set for signal measurement; it takes more time to prepare than to test !

I will add this circuit to my list - also look at leaving out the use of OPAMPS - try using discrete components like single transistor (and FET) amps and filters - I have not looked deeply into the circuitry here yet - I have a general idea from the beginning of the thread and I will make a device similar as best I can then start comparing and adding here.

Also look at using a bridge circuit for increased sensitivity output into an FET input section - lots of gain and high S/N ratios here !

I will be using this as a possible low level input standard; adding filters etc - I need to verify what is called a-wight and c-wight filter design.

(EDIT:(!): Weighted filters I found were used to test microphones I should know I had to design some for that reason some years back - I totally forgot what the reason was til I read up on them. It was said that as such these filters were best suited for singles tones (to transmit to microphones for testing) due to low distortion (which wasnt mentioned (!); they are not suitable for broad range of freqs - also cant remember how the bandwidth are on them - the idea was to get really low distortion; might be suitable for Spiricom but I dont think that was an issue and probly not necessary.

As for not using OPAMPS - possible mixing of radio frequencies inside or near them...simpler circuits may leave out interference but then again the crystal radio was simple; just my own processing.

I will be doing up streams on power supplies and noise, filtering and such, and building my prototype input amps and filters soon; then I get to hook it all up and start the real research !

As I may have mentioned I only scanned this thread - havnt studied it but I have the idea; I will add this to my list; try it first then start adding here; I happen to have found a large bag of old relays - I knew they would be good for something...)

I will stay tuned here !

Mr Zeta

Hi Keith & all,

sorry, didn't have much time during the last weeks. Here's a short update of my experiments:

I built the amplifier and the power supply on perfboard and into cases. I also built the diode, without the magnets, into a screened case (coffee can) in order to see if the voice-like sounds are perhaps picked up radio stations - they aren't (I didn't assume this anyway, just wanted to be sure). I also did some measurements at the diode at different reverse bias voltages (0...200V) and found out that there's a voltage range with maximum noise, but not necessarily a maximum number of "voices" (these "voice-like sounds" also occur outside of the range of maximum noise).

On this page I documented my results (including some audio examples).

I'm not quite sure about the role of the magnets. In my previous experiments, voice-like sounds occurred with or wihout them. Perhaps static magnets are the wrong way to go; perhaps I should also try coils. I'm currently looking for information about theory and practice of scalar energy, and thinking about ways to use it in in TDC experiments.

I also tried other types of diodes, e.g. silicon diodes or zener diodes, but germanium diodes worked best concerning voices.

Stefan
