  1. In the past 2 weeks I was experimenting with a circuit that utilizes race conditions on the R and S lines of a digital flipflop. My idea was that spirits could influence the runtime of clock signals and thus generate fluctuations in the dc component of the output signal. I had a nice noise signal and also fairly good voices. So far so good. While trying to improve the signal to noise ratio I accidentally ripped off the driving clock signal from the flipflop. To my utter amazement the voices still remained. Then I methodologically stripped off any electronic components until everything that was left was the final OpAmp stage that amplified the flipflop signal for the line output. Voices were still there! After some more investigations I finally found out that the noise was coming directly from the resistor network I used to bias the OpAmp. It was a simple 1:2 voltage divider made of two 2k2 resistors and by pure accident I took two very old carbon compound resistors. As I replaced them by metal film resistors the signal was gone. So my current circuit I am using now is this one. The signal it produces has much from the coherer setup but the voices sometimes are really good. The behavior of this circuit is varying. Sometimes I got almost clear voices and then later more spiky ones with good modulation but bad quality, some voices that are more the envelope function of speech and some voices are completely over limit! The difference compared to the coherer voices is that the signal to noise ratio is really outstanding and I could decode lots of them without post processing even though they are still hard to hear for an untrained ear. I was totally fuzzied that I suddenly get strong EVP signals from a simple biased OpAmp. Even with a polarized cap from the center of the voltage divider against ground I still got strong impulses (the envelope style voices). I never had this before and I built hundreds of amplifier stages like this, so this must be something new! From a session I did not archived I deciphered the following. The spirits picked up my idea of working with graphite/carbon and conducted experiments and researches to "meet me in the middle". They said it is my concept they are realizing and called me "professor". I don't know if this an academical grade in the hereafter but it certainly was motivating anyway. Then they said it works very good but I should give them more time to improve their technology. I talked to Michael Lee in our research group and he quickly replicated my circuit. It was almost similar to a design he made a year ago and called "whistler". He sent me a sample and it showed many of the qualities I had found in my audio exports. threema-20210702-141833834.aac I have the feeling that maybe we will face a breakthrough caused by research done in the hereafter and a new portal is starting to open. I would like if more people would replicate this easy circuit to check if they get similar results.

  2. In my ongoing research to manufacture my own CCRs I again experimented with epoxy glue mixed with graphite. This time I wanted to achieve lower resistance values and I mixed in a lot of graphite. I placed the 'blob' between two thumbtacks I used as electrodes. The resistance value is around 13 KOhm now. I placed this new component into my circuit and recorded the signal. A lot of crackling noise was in and some fairly good pk modulation. Here is the raw audio:Sample Thumbtack CCR-2.wav Here is the processed audio:Pocessed Sample Thumbtack CCR-2.wav
  3. Friday night I left my basic Sony recorder hidden in a church very local to me here. On reviewing the recording I have discovered some anomalies, some OK and some not so OK. However there was no one present in the church at the time and the recordings where taken between 1 a/m & 4 a/m. It would be rewarding to have some feedback regarding these uploads, what do you think the voices are saying and what do you think the banging sounds are. I don't really seem to receive as much feedback from members, why I don't know so please let's have some more feedback.

  4. This paper has a scientific focus and in it I'm trying to outline a model for voice ITC in the particular case of coherer reception. I dedicated this work to the whole Varanormal community and especially to Jeff. I wouldn't have made it without all of you. The Coherer Effect.pdf
  5. I started a new series with experiments with LDR's (Light dependent resistors. These are semiconductor components that are changing their impedance if exposed to light. I had the vague feeling they might produce usable noise for ITC under certain conditions. My investigations are not finished yet and currently I am unsure if this is yet-another-noise-source (YANS) or if there is more in it. Results are ambigous so far. In my current setup I use a yellow LED with a low current of 0,5mA that projects it's light onto an LDR. Both are sealed in a black plastic tube to protect the LDR against ambient light. The voltage across the LDR is pre-amplified and recorded. It is pink noise so far. I combined the noise output with Michael Lees ML application. From a sequence of roughly 4 Minutes I could distill 45 audio samples which are pretty goos. Most of them in german but also some in english. Andrés: Andrés.mp3 This audio was nice. I got a "hangup" in the ML algorithm that cause a series of phonem repititions. Directly after that incident I got this message. "Es hakt" -> "It hangs":Es hakt.mp3 "Massen Krieg" -> "Masses war": Massen Krieg.mp3 "She's a christ": Shes a Christ.mp3 "Sie war der Anschiss" -> "She was the scold": Sie war der Anschiss.mp3 "Streber" -> "Nerd":Streber.mp3 "Our answers are keen": Our answers are keen.mp3 "Er verwandelt sich" -> "He changes": Er verwandelt sich.mp3 When my experiments are finished I will put a detailed documentation into the experiment section. Moreover I am planning to write a study paper about using an LDR for ITC provided the results are encouraging.
  6. 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.

  7. Germanium diodes were a huge research field for me in the past. I tried numerous designs with single diode, arrays and feedback. In general the noise germanium diodes are producing is pink and rough in sound. Similar to the coherer sounds the germanium noise produces voices with a good SNR but bad intelligibility. However the voices are less croaky than with the coherer.

  8. In this post I want to share my audio samples i made by use of coherers. See the experiments section for more details. A coherer is a small glass tube or a piece of transparent hose with electrodes at it's end in a distance of some millimeters. It is filled with conductive granular media. I used coherers with nickel, silver, iron, aluminum and graphite/carbon particles.The particles have lose electrical contacts. If a small current is routed through the coherer it starts to emitt strong pink noise. In the noise there are lots of spikes and cracks and strongly but poorly modulated spirit voices. The intelligibility is Class C in maximum. 1.

  10. I have a work in progress of a spirit serial terminal application. Originally I intended to make a spirit morse decoder but it came out that the signals reminded me of RS232 serial data. Thus i hooked it up to a terminal program and got a nice mess of characters. I decided to write an own terminal program that just lets through the letters of the alphabet and numbers. The rest is discarded. It's almost working now. The electronic employs a germanium diode noise source and a discriminator circuit that gives me freedom yo decide what parts of the signal i want to use. The impulse are setting and resetting a flipflop that generates a nice stream of digital pulses of varying length. This signal is directly feeding the input of an RS232 comport on my pc.

  11. 1. Abstract It was more by accident that we experimented with noise impulses in our setup because they were so abundant in the signals we recorded. First we thought that those spikes were just interference signals from common electric sources like power supplies, electrical machine, CFL a.s.o. After I denoised a sequence of spikes by accident I was amazed to find out that they also contained speech patterns. That was the start of a quest for the meaning and characteristic of spirit spikes or spirit impulses as we called them since we knew they were not interference. The fascinating thing was that by proper signal post processing we could recover a good voice part even from just a small bunch of impulses. It was logical to devise a test setup that was designed expecially to scrutinize these impulses we so far just analyzed as a byproduct of other experiments. I wanted to find out if we could gain good quality voices from pure impulses because this digital representation as impulses is practically noise free. 2. Test setup The challenge was to design a circuit that uses a noise signal as an input signal and generates random impulses from them. I had the idea of making two independent noise sources with the very reliable OA9 diode. The preamplified noise would trigger the set- and reset inputs of a simple RS-Flipflop. The idea was that randomly setting and resetting a flipflop would generate trains of impulses with varying frequency and duty cycle. Electronic schematic of first RS-FlipFlop EVP receiver The schematic shows very clearly the two indentically designed noise generators. The trigger sensitivity for each R- or S-channel can be adjusted independently. I provided two LED's with different colours to indicate the SET or RESET state of the FlipFlop. The idea was to give the operator an indication of the triggering count and if the triggering is symetrically or not. For this test I made a breadboard design and no real prototype. 3. Test results The circuit worked pretty much as expected and the signal was very symetrically. That means that SET and RESET events were more or less in equilibrium. The results were very encouraging if a reasonable amount of denoising and hp-filtering in audacity was applied. I was amazed since it was proven that voice patterns coded in impulses can be recovered up to a certain amount that makes the voice intelligible again. You can hear a collection of samples here. 4. A new design The results of the first design were good but I valued it as a bit too complicated. My consideration was that maybe one noise source could do as well and I wanted to use the excellent trigger facilities of the famous monostable multivibrator circuit NE555. That gave me the base of a new design I made 9 months after the first one Electronic schematic of 2nd design You see that this schematic is much simpler. It contains roughly only half of the components from the first design. Here is only one noise source. The amplified signal is feeding the trigger and threshold inputs of the NE555. Basically the trigger input corresponds to the SET input of a RS-FlipFlop and the threshold can be seen as a reset. The NE-555 triggers its internal flipflop if the voltage on Pin 2 undergoes a trigger level of UB/3 = 4V. The output (Pin 3) is set to HIGH then. If the voltage rises above 2*UB/3 = 8V the circuit resets the internal flipflop again.. 5. Results of test with 2nd design Obviously the distribution of impulses is not that symetrical as with the first design but this had no remarkarble influence on the signal quality. The first track shows the raw signal. The second track shows the signal after processing with Paulstretch. This is an intelligent algorithm in audacity designed to stretch a recording by filling the gaps that naturaally occurr by stretching with data that was synthesized after the specification of the raw signal. In our practice Paulstretch proved as very valuable to convert impulses in readable voices. The third track is the signal from track 1 after 18 dB of denoising which is moderate. The picture above shows the impulse trains in zoomed presentation. As expected frequency and duty cycle are varying randomly. A sequence of experiments showed that much impulses do not necessarily lead to good voices despite as one might think because more impulses mean more entropy and more opportunities for the spirits to form voices. This is not the case. In fact it proved that less impulses give better results than much impulses. The reason is that less impulses are an outcome of higher SET/RESET levels on the NE555. Only the amplitude maxima (positive and negative) are triggering impulses thus the noise below does not trigger impulses and only the high impulses of strong voices are making it through. See it as a special form of signal to noise improvement in the time domain. The picture below shows a signal with less impulses in three parts. Left is the raw signal, in the middle the signal after Paulstretch and on the right after denoising Hear the audio sample corresponding to the picture here. You can hear that the rhythm of the speech is very good perceivable even in the raw signal. After paulstretching the result is of so good quality that denoising is almost obsolete. The last picture shows the spectrum of the raw signal. The spiky outline already shows a good modulation with voices. You can hear samples made with this design in the same audio directory as specified above. 6. Conclusions It was proven that impulses triggered by a random noise signal are representing a spirit voice signal in an, I am tempted to say, digital form with very good signal to noise ratio. The paulstretch function in audacity is an excellent tool to convert the impulse trains into a readable signal.
  12. 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
  13. 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.
  14. 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
