The Coherer Mill

[Andres Ramos]

From my past experiments with the coherer and my experiences with the plastic foil crumpling, I had the thought of looking at the coherer as a component which is capable of opening and closing thousands of little electrical switches simultaneously. If we are using filings from nickel or iron than those may be excited by a rotating magnetic field and are causing permanent switching of electrical current. I made a video from the prototype I made and exported some samples. Intelligibility still is not good despite I can decipher them fairly good if I listen to them in a loop. This technique generates almost noise free voices with a very good signal to noise ratio, though sadly still distorted.

I have a few filters for "raspy" voices that we could try. Send me some raw samples. Also, the similarity to my spinning top visions is eerie.

Hello Mr. Ramos,

I'd be interested in getting the Entire Un-Filtered audio file.

Very cool, guys. Thanks for your help!

See the attached files.

One ist the pure raw signal. The second one is the processed. Maybe you want to use it for comparing.

Today i widened the scope of the coherer mill experiment and tested different distances between magnet and coherer as well as decreasing the coherer bias. The exported samples sound better with less post processing. Apart from one sample I made them in a way that the original and unprocessed sample is at the beginning and the processed version  right behind it after a small pause.

One problem I identified is the vibration of the motor gear. This mechanical movement is shaking the coherer filings and adding unwanted noise. I am thinking about an improved mechanical setup with a brushless 230V ac motor suspended on damping elements. Another idea would be a simple mechanical setup with just a crank handle. This way the user could impose his own rhythm on the rotation of the magnet up to a certain limit.

Another thing to test is if the signal improves by more or less filings or in other words more or less space for them to move. Providing a coherer assembly made with one electrode working as an adjustable piston in a plexiglas tube could be an easy approach.

Made another test recording directly on my smartphone to check out wavepad on Android. There i got this message.

"Motor bremsen" -> "Slow down motor"

A clear hint for my next setup. Will make a coherer mill with a crank handle.

I'm remodeling the coherer mill. Now it's driven by an synchronous 230 VAC motor that runs with only 4.5 rpm. Moreover I now can route white noise from a zener diode through the coherer. Tests are in progress.

Some more refinements to the mechanical assembly today. I replaced the glass tube by a piece of transparent hose with brass screws as electrodes. Brass is non-magnetic thus the nickel filings don't "stick" to the electrodes. Besides, the plastic hose is much easier to work with compared to glass. Yesterday I broke the glass tube and cut my fingers. Bloody mess!

The rotating magnets themselves are now small neodynium disk magnets fitting into plexiglass rods. These rods themselves have magnets to fix them on the rotating beam. This way the magnets can be placed freely around the coherer.

Yesterday in my first test, still with the glass tube coherer, I got encouraging messages from the spirits. They said they would be ready today for tests and I should count on them. Good to have a family and friends over there!

In my tests from today I got lots of more positive feedbacks from them although the adding of white noise did not prove as substantial. After playing around with the dials for a while I turned the white noise down to zero without getting results of lesser quality.

Another interesting thing I discovered was that the coherer produced noise even without a bias! That was strange and amazing since without a current the only source of the noise must have come from the rotating magnets and their acting on the filings. I guess that it's kind of an induction process taking place here. However the produced noise had no better quality than all the other ones I have tested in the last two years. By denoising it I found the usual croaking voices I already knew since my experiments with zincite. So nothing special here.

The results of the coherer signals are a mix of spikes and noise with more spikes than noise. The only way to process those signals for me so far is using Paulstretch in Audacity which is not the best but the only means to improve the signal currently. Hoping for a better algorithm in the future.

Here are some of my results from today.

• "Das Anfachen sehr gut gelaufen" -> "This was a very good start!": Das Anfachen sehr gut gelaufen.mp3
• "Herzlichen Glückwunsch!" -> "Congratulations!": Herzlichen Glückwunsch.mp3
• "Wir werden noch besser" -> "We are still growing better": Wir werden noch besser.mp3
• "Wird schon größer" -> "It's already growing": Wird schon größer.mp3
• A long sentence i did not decoded yet to show that the coherer can produce a stream of voices with more or less constant quality: Long Sentence.mp3
• "Herr Professor, du bis noch mein Tod" -> "Professor, you are killing me!": Herr Professor du bist noch mein Tod.mp3
• "Wir sind Rest" -> "We are the leftovers": Wir sind Rest.mp3
• "Du wirst noch viel begeistern" -> "You will inspire many more": Du wirst uns noch viel begeistern.mp3

 

In fact this was a very cool kind of transdimensional cooperation. I am infinitely grateful to my otherworldly friends for these experiences. May you all be blessed with love my family members.

I did another test today with Michael Lee's ML application that is optimized for impulses. I got some very good results from it combined with the coherer mill.

• "Ascension": Ascention.mp3
• "Season Cypress": Season Cypress.mp3
• Forward:"Ascent Ma", Reversed:"Macht Messer"(Maybe "Makes measurement"):Ascent Ma - Macht Messer.mp3
• "It's a sign": Its a sign.mp3
• "Access yes": Access yes.mp3
• "Es ist Scheisse"(It is shit): Es ist Scheisse.mp3
• "Setzt immer diese Sequenz"(Always put this sequence): Setzt immer diese Sequenz.mp3
• "Ist alles klar"(Everything is alright): Ist alles klar.mp3
• "Ja, das ist halt alles hart"(Yes, everything is tough!):Ja das ist halt alles hart.mp3
• "Smaragd ist"(It's emerald): Smaragd ist.mp3
• "Andrés, es ist erlöst"(Andrés, it is redeemed): Andres es ist erlöt.mp3
• "Blechmünze"(Tin coin): Blechmünze.mp3
• "Ist Test"(It's a test):Ist Test.mp3
• "In service":In Service.mp3
• "Mrs. Merkels stress": Mrs Merkels Stress.mp3
• "Du siehst Hass. Es löst. Wird Zeit"(You see hate. It's dissolving. Time has come):Du siehst ist Hass.mp3
• "Es ist Wahnsinn"(It's madness): Es ist Wahnsinn.mp3
• "Er erreicht das Ziel"(He reaches the goal): Er erreicht das Ziel.mp3
• "Schwester" (Sister): Schwester.mp3
• "A sadist": A sadist.mp3
• "Uns verhasst" (We hate it): Uns verhasst.mp3

I got lots of more message with a content around an "Everything is very hard" context. Remarkably the spirits adressed that Mrs. Merkel is suffering from stress, what obviously is true.

The results are amazing Andres. I couldn't hear everything on all sound examples, but so many were clear and unmistakable. Really cool!
