Here they are!
the specifications for the basic replication: the "U" shape = the most documented one and the one who has produced "the electrical incident", as Pascuser call it, or "the power avalanche" (or just "avalanche"), as I call it - the original straight one has too produced the avalanche (with up to 1 m long of spike voltage) but less studied until now. (Thanks to BlueDragon for his comments I have "freely adapted" for the publication here
).
(U shape: the cheapest and easiest replication but enough to registrar the first level of o.u.)
THE "BAR":
-
Diameter:
A tube of hollow copper, of 12 mm of out diameter.
The purpose being to place the copper in the magnetic field of the winding.
-
Thickness:
1 mm thick.
It would be not to avoid the skin effects but it is simpler to have a hollow one, to drill a hole there or to weld a spring pin of 4mm to leave inside.
In this design, because of the frequency, most power will be on the mm of the hollow copper. So some simple hollow copper is an easy way out and it is a cheaper than solid copper bars.
-
Shape:
Cylindrical.
In a general way, it is always preferable to make circulate currents in cylindrical drivers, rather than cubic or other, because there is for the latter particular effects at the levels of the edges.
In every case, prefer cylinder to any other shape for U shape.
-
Material:
Any conductive and not conductive material would be used, but the power obtained at the output would have a direct relationship with the number of free electrons of the main atom of materials. (Copper, silver, zinc, etc.) The copper is the most common, for a first reproduction, is better to go with the copper.
-
Number:
1 only simple pipe.
Tested with a single tube for the simple and good reason it is because the whole tube has to immersed in the magnetic field. If we use several pipes, then all the surface of the pipes are not immersed = > the results will thus be bad or low, according to the power of the applied field.
-
Assembling:
A single type of assembly: 1 meter of copper pipe, with a cut in the middle of the U, spacing of 1 in 5mm with insulation.
-
Note:
Needs to understand that the U is in fact only a mass of copper of a certain length which must be immersed in a sinusoidal magnetic field with a particular frequency.
THE COIL:
-
Diameter:
Related to 1.5mm ² maximum of section.
-
Kind:
A single solid wire to wind the whole U, without " cut + weld", and no litz wire.
An enamelled wire like for flyback, or "telephone wire", diameter of 0.4mm to 1mm can be enough, the objective being to build a coil which creates a regular magnetic field.
-
Material:
Copper cause cheap and mostly use in electricity.
- Isolated or not?
Insulated, or enamelled but with layer of insulation between winding and bar.
It is necessary that the winding is isolated of U for the simple and good reason that the objective is to produce a magnetic field in which will immerse the U.
We winding close around the U to limit the power necessary, because the U is really "excited"(really "got excited") by the magnetic field. If the designer is capable of supplying a magnetic field ultra powerful, the winding necessarily is not as necessary to be stuck on the pipe.
-
If insulated, nature of the insulating material and its thicknessStandard insulation wire of telephone (the girdle of the phone wire, the small girdle/loom surrounding the copper wire, and not the big girdle/loom which binds the pairs of wires), or as the voltage used in the winding, the varnish put on the enamelled thread is widely enough.
-
Number of turns:
Looks to be an important datum which influences the tuning of output and input.
It is our pet peeve, but actually, the objective being to produce a uniform magnetic field, the winding with joined spires is recommended.
-
Number of layers:
Only 1 to have a uniform magnetic field.
-
Note:
If we use the enamelled wire, make sure that there is no conductivity between the U and the enamelled wire.
LIST OF THE EQUIPMENTS TO RECORD THE OVERUNITY OF THE BAR ITSELF:For the generator of frequency, use either a generator of frequencies of laboratory, or a Chinese generator with AD9851.
The generator of frequency of laboratory should allow to deliver up to 10 volts and 200 mA, what is enough for the beginning.
The DDS AD9851 will require necessarily a pre-amplifier and an amplifier.
It is not advised to connect the AD9851 directly on the winding: the amperage will be too low and potentially the AD9851 is going not to like!
Cheap way: it is thus necessary to turn to a DDS AD9851 followed by an amplifier for the frequency band 3Mhz in 6Mhz range. Unfortunately, these amplifiers are not common.
For the reading of the power in input of the U and out of the U, the various threads of the forum of Conspirovniscience.com speak about it. [You can Google for raw translation to have ideas but I will try to translate one or two threads of.]
Looks far to be easy because it is very complicated to obtain a power (with caring cos.Phi - power factor) from an unclear sinusoid.
The only really applicable solution it is to equip itself with not inductive resistance to take a part of the current, then make screen shots of the oscilloscope, then to do the calculation of the powers manually time after time (manually = via spreadsheet or a software).
An oscilloscope 2 ways minimum, 4 ways better, which connects to the PC where we are capable of getting back information directly on the PC for data treatment - the thread of PascUser is an example for this kind of processes.
VARIOUS SPECIFICATIONS:- Cut of the bar perpendicularly to its length.
- Spacing of 2 to 5 mm dielectric insulation.
- Compensation of the loss of diameter in the separation by an any insulating material for a winding of regular shape and diameter.
- Ending of the extremities of the winding so that it does not take off, and place a small cardboard cylinder at the end of copper to continue to wind little beyond the copper, from 0.5cm to 1cm.
- Installation either of a wire of short circuit of 1m of length, or a system of coil plus variables capacitances, between both extremities of the very bar to tune the output of the U.
- Installation of a load in parallel of the output tuning circuit (bulb or linear resistance more ideally for the measures and the calculations of output power).
- Feeding of the winding either directly by a generator of frequencies which can deliver a range frequencies from 1 to 10 MHz, or an equivalent system with with very low consumption but being able to deliver enough power.
Generally, in input to give between 5 and 10v for 30mA in 500mA, if we have a waves generator of high-tech laboratory, otherwise to use a DDS AD9851 to generate the frequency, then place after an amplifier HF which is linear on the frequency band 2Mhz to 8mhz. Generally, needs to be contrusted, or to order to shops for American radio ham and to import one.
