Continued Experiments and Observations 2013-04-05 to 2014-04-31

What follows are the continuing experiments we have carried out in detection of naturally occurring ultra low frequency phenomena, over the past year. Tony lives in California, USA and Peter lives in Scotland, UK, so our geographical difference affords us the ability to do joint experiments and compare our recordings. The previous year's experiments can be accessed by clicking on the 'Research Experiments 2012-2013' bar on the Home page. Additionally, more background can be gained from our Theory page, also accessible from our Home page.

The purpose of these tests was to detect naturally occurring ultra low frequency electrical and magnetic phenomena. We also wanted to see the effect our geographical positions had on the events we detected.

We each have built identical apparatus, consisting of sensor circuits, a Velleman VM-110 USB, analog to digital converter and our PC's running Abacom RealView 3.0 chart recording software and a Dataq DI-149 Analog to digital converter with USB interface running its own software called Windaq.

Some of our sensors were based on earlier designs described on the home page of this site, but were improved and enhanced by our collaborative work during the past year.

The Op-Amp Sensor: This sensor consists of a J-FET Op-Amp IC chip, with a high gain inverting feedback and open (not connected) inputs. There is a secondary amplifier stage, with a single stage diode, resistor and filter-capacitor integrator output circuit. This sensor is enclosed in a shielded steel case. This circuit is not operating in self-oscillation, but its output is the product of a natural daily cycle. This sensor reacts to ULF energies that can penetrate the steel shielding of its case. We have discovered in the past year, that due to the extremely high gain levels used in this particular sensor, it reacts to changes in ambient temperature as well.

The E-Field Sensor: The detector element, is a small antenna. In these tests, we used a 7 foot insulated wire as the antenna. In some tests a large metal junction box was used as the antenna element. There is a capacitor to ground, at the output of the antenna, to provide a low resonant frequency and to bypass any RF energy detected. We have discovered that this capacitor is a very important part of the detection scheme in that it allows for tuning of sensitivity to different natural ULF frequency 'bands'. The amplifier is an LF347 J-FET quad Op-Amp IC used for two stages of amplification. This amplifier is modulated by the naturally occurring scalar energy. This serves to further enhance sensitivity, beyond simple amplifier gain Lastly, a dual stage integrator circuit, integrates the electric activity into a varying DC voltage. This sensor circuit (except for the Antenna) is enclosed in a shielded steel case.

The Aether-Magnetic Sensor: This sensor has three detecting or enhancing stages.

First, a Barkhausen detector. consisting of several hundred turns of copper wire wound around a steel plate type lamination core assembly, common to transformers and power inductors. When exposed to ultra low frequency changing magnetic fields, atomic level Barkhausen domains in the core, generate pulses that are induced into the copper winding. We use standard electrical transformers as the Barkhausen sensor. In this test series, we have tested many different types of transformer as a detecting element.

Second, a 2200 uF electrolytic capacitor is connected in series with the coil. This capacitor functions not just as a DC blocking element, but also as a detector that generates a small ultra low frequency voltage, in reaction to the naturally changing ULF field. This places a continually changing bias on the Barkhausen coil, which has the effect of making it more sensitive to magnetic activity.

Third, the amplifier itself, like that described in the E-Field Sensor, above, is modulated by the naturally occurring scalar energy. This serves to further enhance sensitivity, beyond simple amplifier gain. Lastly, a dual stage integrator circuit, integrates the Barkhausen pulses into a varying DC voltage. The transformer is normally mounted in a steel case. We have tested it in free air and in aluminum, copper and lead enclosures as well,

The Caduceus Coil Sensor: The original Caduceus coil detector was invented by our late colleague, Brian Sallur, of Western Australia Radio Observatory, to detect magnetic energies from the Sun and Stars, as a tool for astronomy. A Caduceus coil, is a coil wound back on itself,on a plastic or cardboard tube form, with 'cross-over' points. This coil has a self-cancelling inductance. In these tests, we used a number of different configurations of Caduceus Coil, including shielded, unshielded, single layer, multi-layer and one wound with 6 conductor phone wire. The circuit is very similar to the Aether-Magnetic Sensor described above, except for the coil itself, which does not use the Barkhausen effect or a metal core. Here, the coil's 'cross-over' points themselves, are the sensing elements.

Duration of Test – 24 hour

Purpose of Test - To compare data recorded at same UTC times and test new circuit modifications.

Findings - Aether-Magnetic recordings follow our local positions with respect to the Sun. Caduceus Coil recording also follows local solar position and picks up other activity as well. Several matches were found by Tony and Peter, between their recordings. The Matches are believed to be lightning strikes that produce pulses that are propagated by the Schumann corridor and are picked up virtually simultaneously.

Discovery of Temperature Sensitivity of Op-Amp Sensor

2013-05-01

Sensors Tested – Op-Amp Sensor

Circuit’s used

Op-Amp Circuit



Details- The Op-Amp Sensor has been discovered to be sensitive to ambient temperature changes. This was found to be the case by both Peter and Tony in separate tests as demonstrated by the images below. The overall wave is still believed to be responding to the same natural ULF influences as before, but this explains the ripple wave on top of the overall wave. It is believed this temperature sensitivity is from the LF347 op-amp, due to the extreme gain used in this particular sensor configuration. Our other sensors are much less temperature sensitive due to the much lower gain used to amplify the detected activity.

Test of Various Transformers as Aether-Magnetic Sensor

Tony Devencenzi 2013-05-10 to 2013-05-21

Sensors Tested – Aether-Magnetic

Circuit’s used – Aether-Magnetic circuit: 2200 uF sensor series capacitor and dual 10 uF Long Time Constant output circuit.

Aether-Magnetic Circuit \Circuits\amag121213.pdf



Duration of Test – 24 hour each

Purpose of Test – To compare the detection capability of various frame type power transformers in the Aether-Magnetic sensor. Mainly from the standpoint of the rated wattage, which determined the amount of steel in the transformer core.

Findings – As usual, Aether-Magnetic recordings follow our local positions with respect to the Sun. Different transformers performed differently in the Aether-Magnetic Sensor. All worked, but the largest transformers didn't work as well, in terms of output level and detail, as the 50 VA Radio Shack (25V / 2A), that we used as our standard. It seems that a transformer can be too large to work well. This is believed to be due to the steel core and magnetic domains it contains, being so large that it averages out or nulls some the detail.

Joint Test 17 2013-05-22

Sensors Tested Two Aether-Magnetic Sensors, One shielded in steel case, one in free air.

Circuit’s used(Aether-Magnetic circuit: 2200 uF sensor series capacitor and dual 10 uF Long Time Constant output circuit.)

Aether-Magnetic Circuit \Circuits\amag121213.pdf



Duration of Test – 24 hour

Purpose of Test - To compare data recorded at same UTC times and to compare a steel shielded transformer sensor to an identical one in free air.

FindingsBoth of our Aether-Magnetic recordings show that a steel shielded sensor (transformer and circuitry) is More sensitive to ULF activity, than one in free air. We believe this is to be the steel case acting as an extension of the Barkhausen domain core of the transformer. Even though it provides electro-magnetic shielding for the transformer, The Barkhausen Domains within the steel of the case, also respond to the ULF magnetic wave and add to the pulses of the Barkhausen detector.
