ELF-VLF MULTIODORNIK ELEMENT - RECEIVER CO-OPERATING WITH MAGNETIC ANTENNA II- PLATE PRINTED
Producer: AVT
The ELF-VLF receiver, or rather a set of receivers, enables reception of mysterious radio signals with extremely low frequencies. It is possible to observe signals of communication with submarines and so-called Schumann resonance.
It is possible only in extra-urban conditions (eg during trips), and this is due to the high level of industrial disturbance in cities. In the city, the described systems can be used, for example, to observe storms and the level of industrial disturbances. Such their use can also be very interesting. A lot of information about the reception of electromagnetic waves at very low frequencies, below 30kHz, as well as about antennas used for this type of receivers, is provided in the article 'Receiving ELF-VLF radio waves'.
The project presents four receivers, designed to receive radio signals (electromagnetic waves) in the range from 3Hz to 30kHz, thus including bands: ELF, SLF, ULF and VLF. The first of the receivers (I) cooperates with a wire antenna, reacting to the electrical component of the electromagnetic field. It was made in two system versions (Ia and Ib). The third and fourth are designed to cooperate with a loop antenna, reacting to the magnetic component of the electromagnetic field. The article also describes the system generating symmetrical power supply voltage and systems improving work comfort by increasing resistance to unwanted signals: two low-pass filters with band respectively 200Hz and 20kHz, bandpass filter, reducing the hum of 50Hz and optoisolator m signals .cz. The described systems do not require tuning or startup, so that even a novice electronics can do it. The big advantage of these systems is the low cost of their implementation.
Note: the project has been divided into 6 parts:
AVT3054 / 3
The receiver for cooperation with a loop antenna is built on the SSM2019 integrated circuit, according to its typical application note. This system is primarily characterized by very low voltage and noise current for very low frequencies. These features in the presented application are of particular importance due to the low level of received signals, which is crucial when we want to receive signals resulting from the Schumann resonance phenomenon.
Includes AVT3054 / 3 printed circuit board and documentation.

The Marble Run Spiral Hoist is the fourth model in the Ugears collection of fascinating DIY wooden mechanical marble runs. The hoist has two types of rails to speed the ascent: the main spiral rails and vertical rails. Turn the crank to lift the colored glass marbles upwards (one marble rises per nine revolutions of the winding crank) to the three-marble storage up top. UGears 70177
