Are you ready, Capt. Z?

Sorry to learn about your Dad.  Losing parents can be tough but you've got him for a time and that can be reassuring.

[Kiwilady]

Wow this will be interesting!  I'm looking forward to hearing about your results.  Capt-Zeanie I've caught some really great evps over the years so if you want a few pointers I can maybe help.

[Capt-Zeanie]

OK, I finalised the build this morning and now testing the components individually to check everything is wired up correctly.

I have the Germanium Pellet  sitting atop of a countersink screw, with another screw touching (as the adjuster) the top of the Pellet, these screws are connected to jumper cable to a breadboard. The relays are in situi either side of the germanium pellet, and again the relay coils are connected to the breadboard via jumper cables.

My setup is to output directly (no amplifier circuit) into my line-in on my PC and into Audacity so I can capture the waveform etc.

So, the first test is to connect the Audio Left Channel to the base of the germanium pellet and the Audio Ground to the top of the germanium pellet. The resistance shows 1K Ohms. The colis are not energised and are not connected to the audio circuit.
I capture the output for 10secs and then played it back. I was expecting just electrical noise. The capture waveform was flat but nosiey as expected. I then stuck my headphones on and listened and I could hear a voice briefly. What, where did that come from?
Anyway, I saved the file to keep and went about trying to see what it was. I processed the file by Amplifiying and then did a noise reduction to clear up the voice. I was surprised to hear "Hello" my own voice..How did this happen.

OK, so I thought another microphone is connected to the PC of the Webcam, could this microphone be capturing my voice as I was capturing the output but I unplugged the webcam and tried capturing again. I did not speak and all I got was flat and noisy data waveform. Correct as it should be. So I tried capturing again this time speaking and uplod cleaning up the waveform I can hear my voice.

OK, so how is my voice being captured without a microphone plugged in on the PC and the only input is to line-in (Left and ground) to either side of the germanium pellet. I discount the circuit and captued again and I got no voice, so I connected the Germanium pellet back up and again I get my voice.

This is playing on me now, as how is this Germanium Pellet able to capture my voice. I am now going to try a few things and will let you all know.

[siguie]

Cool!

In the original experiment I recall "hello" was the first recognizable word

[Capt-Zeanie]

lots of playing with different checks.

I have identified that for some reason, Germanium is acting as a microphone when pressure is applied, a bit like a piezo crystal can do somehow. However I do not have a diaphragm, so the Germanium is is able to detect my vocal vibrations and general a small electrical signal voltage which is then passed along the cables to the input connection on the PC/Recorder. The more pressure applied by the screw lowers the resistance but raises the recording level.

So, in the Scole Experiment they were encouraged to increase the supplied pressure but they claim the germanium could not record the audio of the PEOPLE present.

The result, is a recording of the communication only, not the voices of those present during the experiment.

[Vlawde]

I had a feeling that was what was going on. Make you wonder how that affects the validity of the Scole experiment? If that was the case, maybe they figured it out and stopped doing it so they wouldn't look like fools.

But yeah, more experimentation is needed

[siguie]

Wait what? That makes no sense

The Germanium is not being powered and there certainly is no diaphragm motion so how is it creating any oscillating signal much less one that mimics your voice?

Been away for a couple of days at the seaside for a short (first) holiday of 2017.

Thought quite a bit about this whilst trying to watch Blade Runner 2049 at the cinema. Whilst the original Blade Runner was good I found this unstimulating to the point I fell asleep several times. You know you have the urge to close your eyes and then think of a few thing and it feels good then you get an elbow in the ribs from the wife moaning that I started to snore.

Siguie, it's not mimicking my voice, it is my actual voice. ie it can pick up my voice, though like you said there is no diaphragm to create the oscillation signal but something is happening. I have posted a question in the ITCBridge forum but it looks like it's not a well used forum. I asked there because I thought that might be a good place as it appears many people have created the Scole Receptor .

I shall be doing more tests Monday between adding a couple of Car Dashcams to my Yeti

[Vlawde]

Could be it's still reacting to your voice by vibrating, so even though it doesn't have a diaphragm it still picks your voice up

[siguie]

Yes everything vibrates with sound that's the nature of rarefaction waves in air bouncing off or being transmitted through mater

Our ears are designed to convert those waves into sound, however, there is no power in the germanium circuit, and no diaphragm oscillating in a mag field to convert sound to an electrical signal that an audio feed with no amplifier could pickup.

I'm not saying that the voice isn't Capt-Z's I'm just saying it makes no sense. It's literally like taking a microphone on a wire, cutting off the microphone AND still being able to record sound from the bare ends.

Even piezoelectric transducers have to generate oscillating currents and they really need to be reasonably well designed to produce a recognizable sounds much less an easily identifiable voice.

Personally I'd check the audio inputs on the computer OR plug directly into a recorder with the internal speaker covered/removed.

[Capt-Zeanie]

Over the last week I have just been perfecting the pressure that the screw applies so I can get the right amount of pressure that is not able to record my voice or other ambient sounds though if anyone was in the house at the time must of thought I was mad as I would be shouting at the top of my voice at this little contraption I have built on my desk.

Then a problem, oppps then too much pressure and I have broke a sliver off the germanium pellet.

No, problem as It's still mostly ok.

The house will be empty for a while allowing me time to start recording properly as the school break is over and the wife will be going back to work to work at the school.

[KlaineyGStudy]

Thanks for the update, don't break any more off the pellet

[Menet]

I love your new signature, Capt. Zeanie.   It's way cool.

I like it too

[Capt-Zeanie]

Thanks, yes a little site revamp as I try more to capture EVP's, though I might just change it again as there was an issue with the Wordpress Theme :-)

I have been testing a bit more and noticed that the conductivity of the Germanium is changing a bit over time, it's as if the surface of the Germanium Pellet is changing and reducing it's electrical properties.
When I first started a few weeks back I could easily get continuity through the pellet however now I am having to apply more pressure and I cracked the pellet again.

[KlaineyGStudy]

Gee that's not good, I wonder why that is happening, be interested to see if anyone has any suggestions

[Capt-Zeanie]

OK, with a lot of shouting (Glad the people in white coats were not watching) I have now got it in a sweet spot and not being able to record ambient sounds.

So playing with it still I am trying to see if there is any interference when the coils are energised with 12v or not. There is a little spike on the recording when the coils energise but not much.

Trying the recordings in Audacity or an Adobe Audition to see which is better at watching the spectrum. Audition is a lot faster and response compared to Audacity.

Um it sounds like you made a point-contact-diode and the sounds you are hearing could then be explained as radio frequency captures. This is basically how germanium crystal radios are made. Germanium is essentially an N-type semiconductor and a few atoms from the contact metal {presumably copper in your case} leaches into the metal essentially doping it and producing a P-type semiconductor.

My guess is also that you are probably in a fairly humid environment or atleast the system is exposed to enough hot/cold for the copper to tarnish and undergol redox reactions with the germanium. This might explain the changes in electro conductivity ... my vague recollection is that point contact diodes were made with gold or relatively unreactive metals.

You may want to throw a drying agent in with your systems enclosure and see how that works

[Capt-Zeanie]

Thanks Siguie

I am coming to the end of my days off (Go back to work Saturday) and I am feeling really crud with my spinal and shoulder pain, so with nothing to do at home today apart from order a new PC as my current one is really getting old now and USB does not work and the sound is intermittent.
I got a the bits to build a Water Cooled Ryzen 7 1800x, 16Gb memory, ASUS STRIX GTX1060 (I had to compromise on this as a GTX1080 is way too expensive) in a nice pure white case with RGB lighting. At least this cheered me up.

Anyway, after buying bits I then spent a couple of hours doing some long EVP sessions with the Germanium Receptor. This was 30mins of silence, 30mins of White Noise, 30mins of Chrome Noise and 30mins of me generally speaking but so  far I have reviewed the first 2 sessions and nothing (as usual for me)

[KlaineyGStudy]

Oh wow sorry to hear you have a sore shoulder and back. On a good note and new PC   too bad about your EVP session . Don't give up I enjoy your experiments
