Home Made Elf Generator, How can I make one?

Hi all! This is my first post as I just discovered this forum

I am not a physicist, and I have only one year schooling in basic electronics a long time ago, just so you know.

I want to make a device that can send electromagnetic waves to stimulate the body and pineal gland (inside the brain). The magic frequency is around 8Hz (not very high).

Now I have read about many such existing devices, but they do not come with blueprints, unfortunately. So I started some experimenting by pulling apart an old speaker to take out the coil, and I have a software that can send out a sound signal at 8Hz and I amplified that signal through an old stereo.
I know that I do now have an electromagnet which oscillates at 8Hz, but I have no idea if this is what I am looking for. The magnetic core is removed from the coil, so there is no physical vibration.

I have read that there are two kinds of waves that comes from EMs and those are E and H, and the H wave is the one useful for my purposes because it penetrates everything when working with low frequencies. Does my old speaker magnet send out H waves?

Also I have a thought that maybe I need an antenna which can send the signal in a particular direction, or can I just send the signal in any direction like a light bulb?

I am not an expert, but is it so that if I manage to make such a generator, those waves would be considered low frequency radio waves so that if I had a radio that could be tuned on 8Hz it would pick up the signal from how far away??

I want to make either some sort of wearable head band or helmet for this, or a device that can be placed on the night stand and give out smooth waves in the night.

Any ideas?

Bare in mind that any frequency that affects the brain will ultimately end up as heat - cooked brain probably doesn't work too well.

I know, I tested the coil with a frequency of 200Hz and the coil became a little heated.. but not with 8hz

Our natural brainwaves range from 1-3 Hz (coma like), and up to 15-40 Hz, and the 8Hz frequency is for meditation and dream like states

The effect of interest is not whether or not the coil becomes hot - the effect of interest is that the absorber of the rf becomes hot. See:- http://en.wikipedia.org/wiki/Radio_frequency_heating

Okay I did not think of that...
Thanks for the link, it was useful information!

What I have to consider would be the intensity of the waves and the proximity to the subject, as the frequency (8Hz) is, what I read, way within the limits (it was mentioned "heating" as low as 50-60 Hz)

But is it possible to turn an 8Hz sound signal into an electromagnetic wave the way I did with the coil? And if so, how can I measure the distance and strength? As I far as I know our brain does not fry from normal radio waves even though they are hundreds of MHz

Most hearing aids have a telecoil for old fashioned phones.
They pick up the EM from the speaker rather than the sound.
This is to prevent feedback.

In any case,coil based speakers produce EM signals when making sound.

But you might want to consider experimenting with bio-feedback devices. Once you train yourself you brain does the work and you won't need any device.

Since they goal, as I understand it, is to have the brain operate in a mode which corresponds to the normal cases of certain EEG properties, then training yourself with biofeedback techniques to achieve and maintain such EEGs seems more likely to achieve the desired result than trying to impose such EEGs from exterior EMFs.

That being said, since the interpretation of EEGs is a medical specialty and since you need your brain to interpret EEGs, successful experimentation in this field may require more than one human being and thus the concept of ethics in experimentation arises.

I recommend strongly against any attempt to influence the human brain with external fields. If you do succeed in modifying the operation of your brain, how would you be in any position to judge if that change is beneficial or the opposite?

Of bio-dfeedback..
As a matter of interest - can you slow your heart-rate down? (52 bpm was my record )

I have not heard much of bio-feedback devices...

However what I do to my own brain is my responsibility, just as the ethics of taking alcohol I am not going as far as using test subjects beside myself, hehe

The link is showing what I understand being a complicated device, maybe there is an easier way..?

Anyways, I'll go have a look at bio-feedback devices!

Perhaps you should dig through old Nikola Tesla materials. He was very much interested in that sort of thing.

I hope this is not a completely idiotic question, but what are these EEG's and this Biofeedback?

Biofeedback, the process of measuring specific, measurable bodily processes then conveying that information back to the subject in real time.
Wikipedia - Biofeedback

EEG: Electroencephalography, the process of measuring the electrical activity of a person's brain.
Wikipedia - Electroencephalography

The former is pretty cranky pseudo-medicine, the latter is a common medical procedure, which is often involved in the former.

ah thank you , definitely sounds interesting...

The only use for Bio feedback I can see in this situation is to connect it between the Elf Generator and my body so that it can tell the generator when to activate...

The Bio f. could for example register when I am entering REM sleep, and then tell the generator to produce a certain frequency... Just an idea of course...


Anyways I have found out that I need a carrier frequency of about 42600Hz to "carry" the 8Hz waves. Does that rule out the possibility to use an audio signal as the 8Hz?

"My initial transmitter of ELF signals consisted of a phase-shift, pure sine-wave oscillator whose output was fed to a 10 Hy soft iron core inductance of 1200 ohm dc resistance. Power level was 9 volts at O.7 ma, or 6.3 milliwatts. This device could cause EEG modification and mood alteratlon in subjects at up to 10 ft. A higher power device constructed in 1973 provided greater effective range, as was expected. Highly specific modulating and carrier frequencies must obviously be withheld for fear of potential mis-use, as are "keyhole" and waveform data, also details of the multiple-source devices producing " soliton" ELF magnetic standing waves." R.B.

As Robert mentions above, he holds back data about the carrier frequency which I found at another site. However I feel that the latter part of the text is unnecessary complicated only to mislead.

I have now a soldering iron, some wire, some ready made coils and a 9v battery

The problem with your set-up so far is that you can't tell if it's doing anything.
I'm guessing your reference to 4 2600Hz refers to some sort of audio signal that changes with the measured response so you can tell what effect you're having on yourself. I'd suggest starting at about 400Hz as this is a frequency you can listen to without driving yourself mad (another possibility) .. so you hear .. say
wooowooowooo
woooowoooowooo
wowowowowowowo
You then tune your gizmo so it avoids and gets you to
Something like that, anyway.

You can test biofeedback by reducing your heart-rate. Count beats during a 30 second period. Hold your breath and count again. Then imagine holding your breath without doing it.. any effect?
