Andres Ramos

Bienvenido Fernando !! Glad to have such an experienced snd open minded soul here on Varanormal. Seems to me the spiritual seekers all have their burden to take. I care for my parents since 8 years. Now my mom is in s nursing home with Parkinson disease and my father is very slowly dying from bladder cancer. My free time also is almost zero.

I already explained the good results I yielded with the coherer devices in the article Research Paper - EVP Reception with Coherers - Basic considerations by Andres Ramos. I decided to scrutinize this effect in more depth and took the graphite coherer as a starting point since it gave me the best voice signals and worked very stable. For my first experiments I used powdered carbon and the graphite powder from a hardware store. In my experiments I wanted to test more materials based on graphite. My next step was to try graphite mines from a papershop. I arranged two of them with ductape on my working desk and fixed two wires to them. A third mine was losely lying across the other ones. Graphite mine setup The electrical contact over the mines was very weak as I wanted it to be. Via a series resistor I routed a small dc current through it with an adjustable voltage from my power supply. The gained results were of the same quality as with graphite powder. Sadly this setup was extremly susceptible for mechanical vibration. It was in fact a microphone! From another project I made i knew another material based on graphite and that was conductive rubber. This is manufactured as small tubes of rubber with a certain amount of graphite mixed with the rubber. I also made a setup with these. Conductive rubber setup The setup was a lot more stable in mechanical terms and also slighly improved in signal quality. Moreover it was very easy to get it to emitt noise. I decided to design a complete receiver around this conductive rubber setup. For some marketing reasons it was coined the "Marconi Mk II" device. The Marconi Mk II device Sadly I don't have an electronic schematic anymore but the design was very much copied and pasted from the zincite receiver while replacing the zincite by a piece of conductive rubber with two electrodes. One with a screw only slightly touching the rubber. The receiver had knobs for rubber bias voltage, volume and also a microphone. By pressing the red button a red LED lights up and the voice of the experimenter is mixed with the noise stream while simultaneously muting the loudspeaker. This feature was implemented to record the questions of the experimenter along with the spirit signals. See the attached test report for more details on the graphite coherer. A collection of audio samples made with the Marconi device can be found here Before finalizing this article i want to mention that I also ran an experiment that I called "Multifeeder". This was in fact a piece of rubber tube with more then one "cat whiskers" and a common electrode. Multifeeder setup I combined all the signals of the three feeders in a preamplifier. However whether the S/N ratio nor the overall signal quality was improved. ITC report 2019-G-003.pdf

I made my first steps in ITC with the zincite receiver I made (Look at topic "1. Zincite as an replacement for germanium in ITC application"). My intention was to find a cheap and easy replacement for germanium since germanium semiconductors are becoming obsolete more and more. But there is also an application with pure germanium that was successfully tested earlier and is said to be a design of Thomas Alva Edison himself. See article here. I don't know if this is true but I wanted to find out if germanium would give me results comparable to the ones I gained with zincite. Thus I bought a disk made of 98% pure germanium at Ebay and constructed a mechanical assembly that allowed me to place it between to electrodes with one of them to be adjustable with a screw. Mechanical assembly of germanium disk holder Since operating the germanium was not different from working with zincite I just replaced the zincite sub assembly in my receiver by the one shown in the picture above. Tests and results Basically my presumptions were proven. Germanium gave the same quality and sound that i already was used to from zincite. The difference was just that germanium was more stable. I already expected this since germanium is a solid crystal structure and not as weak as zincite. So from a signal quality viewpoint the germanium circuit can easily replaced by zincite. A collection of exported audio sounds can be found here.

Encouraged by my first experiences with germanium semiconductors I was looking for means to improve signal quality and S/R ratio (signal to noise ratio). I frequently heared from other experimentators that different kinds of feedback can improve the voice signals. It seems that positive feedback causes a system to become unstable, adding more entropy to the setup the spirits can use to form speech. The most common form of feedback used in ITC experiments is positive acoustical feedback. I considered if maybe feddback on an electronic level would do as well. Thus I designed the following electronic. Electronic schematic of germanium transistor receiver with feedback The circuit is rather simple. A germanium transistor AF137 is used as the noise source. The negatively biased Base-Collector diode of the transistor is the originof the noise. It is routed via C3 to an operational amplifier with a voltage gain of roughly 40. Via the potentiometer R10 the amplified signal is fed back phase synchronized into the transistor by using the emitter. Original and feedback signal "mix" in the germanium crystal. Test and results In the experiments there was definitely a change is the signal spectra depending on the feedback settings. Spectrum without feedback=0 Spectrum with feedback just before start of self oscillation From an electrotechnical point of view this behaviour is nothing paranormal. Feedback always is changing the frequency response of a signal. All active filters are working this way. I had the impression that with high feedback the intelligibility was slightly improved however certainly more because of the bandfilter properties and not by some paranormal effect. The recorded signal required a certain amount of post processing and the results were comparable to my previous experiments with zincite, maybe a little better. A collection of exported audio samples can be found here. See the attached test reports for more details. ITC-Report 2019-B-01.pdf

Thank you Kim. Great top have you aboard!

Very good! Almost a style guide.

The use of the coherer effect is relatively new for ITC. The first occurrence l encountered in an article of the german VTF association. The carbon powder cell described in this article appeared very familiar to me as I had intensively studied the structure of coherers and thus the works of Branly, Marconi and J. C. Bohse. A coherer is an amazingly simply and effective early device for the reception of radio wave energy. It contains fine granular media, particulary metal filings of iron, silver and nickel and two electrodes in lose contact with the filings. The filings are normally covered with thin films of non-conductive media like oxide. In idle mode the coherer has a high impedance of several megaohms. If a radio wave hits the coherer there is something amazing happening. In a moment of some nanoseconds the impedance drops down to some 10 ohms and the coherer may switch a relais or drive a lamp with current. Apart from this amazing effect I discovered that a dc current running through the coherer, provided a proper configuration of the filings, generates a strong noise! To scrutinize this effect I fabricated coherers myself. What you need for this is a file and different metals. I used iron, aluminum and silver I used a vise to fix the material and then filed it down until I had enough filings to fill a small glass tube with them. I made a simple device to apply a voltage and an adjustable current to the coherer. On a lathe I cut a plexiglas rod and drilled in a cavity with an electrode at one end to fill it with filings. The second electrode was a screw thus I could adjust the pressure on the filings very accurately. Experiments with the coherer setup I made tests with iron, aluminum, a nickel-silver mixture and graphite powder (used for lubricating locks from a hw store). Iron gave average results. The noise was not very agile. Aluminum was very eager to noise with huge amplitude changes but it was unstable. The noise ripped off very fast and the coherer needed to be readjusted. An outcome of the fast oxydization of aluminum in air. See below two signal examples from my tests. Aluminum noise signal Graphite Powder signal I analyzed the spectra in Audacity. They were more or less the same. For me that was evidence that the signal quality was an outcome of the naked effect and not the material that emitted the effect. It seems that any conductive material in lose contact would do. What really differed between the materials was the stability of the noise. From this point of view nickel-silver and graphite were superior over the rest. Typical spectrum of a coherer signal Principally the voice quality is rather bad, however there is a steady stream of voices and thus some of them have better quality if you catch the right moment where the actual spectral composition of the noise was at maximum. I needed to do a lot of post processing, mainly denoising and filtering to achieve acceptable results. A collection of audio sample exports as mp3 can be found here. Later i made a heavy simplified version of the coherer that also worked excellent. It contained a piece of plastic tube and two screws as electrodes. See the attached test report for more details on the coherer tests. ITC-Report 2019-G-001.pdf

Most ITC aficionados start with the gold old germanium diodes as noise sources for ITC sessions. The noise structure is more rough compared to silicon diode noise and the noise much louder than with the latter ones. The best diodes for ITC I ever tried were the old OA9. These are very rare now and probably obsolete. Years ago i stumbled upon an article about the work of Oleg Lossew. He was a russian radio technician and the first one who scrutinized semiconductor properties of certain materials like crystals and sulphite- and oxide layers. He was supposed to be the first one who encountered the LED effect in carborundum crystals as well. Then I found the website of Nyle Steiner who turned Lossew works into real practice. I followed Nyles advices and fabricated a zinc oxide substrate by burning a piece of zinc galvanized iron in the flame of a butan torch. A layer of white and black zincite flakes was the result. If you now take the iron sheet as one electrode and a spring beared steel needle as a second, slightly touching the zincite flakes and you route a small current over a resistor in series through it, then you'll hear a strong noise if you are tapping the audio at the zincite electrode and pass it over to an amplifier or recorder. I made a real device from this setup. The noise is pretty strong with spirit voices but of very low quality. However if you give the spirits some time to align with the physical properties of this setup, it will go better. A drawback is that the bias you need to establish by properly placing the needle is unstable. It take some seconds to find a place for the needle tip that gives good noise. Sadly by the time because of the weight, the needle will press itself though the soft flakes and the bias will change. So readjustment or even replacing of the zincite substrate will be necessary.

That'll be a great help for us! Thank you Chris:

Hi Michael. I take a movie from the setup with my smartphone. When it's done i use the android app Grabi to decompose the movie into single frames to watch. It's a bit tedious but if you are taking the effort then nothing will slip through your fingers. In total i analyze about 300 to 400 frames.

The most simple setup for obtaining images from moving water is using boiling water in a transparent kettle and taking shots from it. See more here More ITC images from boiling water

You're my hero Michael!

My name is Andrés Ramos. I am an electronic engineer and live in Northern Germany.
