	Hacked Gadgets - DIY Tech Blog » Blog Archive » Top 5 Coil Guns
		When we get the power storage solution to make a weaponized coil gun that exceeds the capabilities of the current rifles it would still take about 50 years for them to be accepted.
		coil guns have just as much a chance of becoming a completely standardized weapon system as any other prototype or experimental weapons out there.
		This is why silenced weapons tend to use lower-power cartridges like a.22 to achieve a [barely] sub-sonic projectile, in combination with a silencer to dampen the noise from the muzzle gas.

	Communications Jargon: Simplex/Duplex, etc.
		The circuit from the switchboard goes to one coil of the transformer, and the other coil is connected to the line between switchboards.
		If have two phone lines (A and B) between the same two switchboards, with two repeating coils at each switchboard, you can connect telephones just as for a simplex circuit, except that the other wires from the telephones are connected to the center taps of the other repeating coils instead of to ground.
		The theoretically even split of voice current at the repeating coil does not always occur in practice, so both these circuits are more susceptible to noise, interference, and cross-talk than the 'plain' connection.

	Transformers, Phantom Circuits and Repeat Coils
		Here the alternating current flow in one subscriber's line is repeated into the other subscriber's line with little energy loss, and at the same time the windings of the coils afford the proper direct-current connections for each subscriber's station to receive a superimposed d-c current for transmitter supply.
		By means of repeating coils installed at the terminals of the wire circuits, a third telephone circuit is obtained.
		With the side circuit conductors electrically equal, there can be no difference of potential between the mid-point of the repeating coil winding at one end and the mid-point of the repeating coil line winding at the other end because the drops of potential for the two parts of the side circuit are equal and opposite.

		The input of selector component M3 is accordingly connected with the corresponding winding of repeating coil Ue3 and the input of selector component M4 with the correspondent winding of repeating coil Ue4.
		The repeating coil thus serves not only to cut off the feed voltage from the switching matrix, but also due to the unequal number of windings on its primary and secondary sections, it permits the alternating speech voltages to be transmitted with a sufficiently low attentuation, assuming that the feed voltage has been suitably selected.
		The terminal of the section of each repeating coil Ue1 to Ue8 that is on the switching matrix side and is not connected with one of the coupling components M1 to M8, is connected by means of a joint wire to a specific reference voltage (e.g.

	Coil
		An ''electromagnetic coil'' (or simply a "coil") is formed when a conductor (usually a solid copper wire) is wound around a core or form to create an inductor or electromagnet.
		The coil tap(s) are points in a wire coil where a conductive patch has been exposed (usually on a loop of wire that extends out of the main coil body).
		A chemistry coil is a tube of spiral form, used commonly to cool originating steam of the distillation and thus to condense them in liquid form.

	What is a Wave?
		However, if the first coil of the slinky is continuously and periodically vibrated in a back-and-forth manner, we would observe a repeating disturbance moving within the slinky which endures over some prolonged period of time.
		As the second coil becomes displaced, it begins to push or pull on the third coil; the push or pull on the third coil displaces it from its equilibrium position.
		When the third coil returns to its original position, it possesses the same amount of energy as it had before it was displaced.

	How to Wind Toroidal Mobius Coils
		While you can wind a mobius coil from single strands of wire, it certainly seems to be a lot more potent when you use a cable made in the manner described here to wind the coil from.
		While working with the coil, be careful not to scrape the insulation off the wires, or the coil will short out and not work.
		You should measure the diameter of the object you wish to place in the coil as a core when it is finished, and start with a circle a little larger than the diameter of the intended core.

		If the first coil of the slinky is given a single back-and-forth vibration, then we call the observed motion of the disturbance through the slinky a slinky pulse.
		The repeating and periodic disturbance which moves through a medium from one location to another is referred to as a wave.
		The first coil becomes disturbed and begins to push or pull on the second coil; this push or pull on the second coil will displace the second coil from its equilibrium position.

		Given the potential value of a T coils with telephones and as an assistive listening device receiver, it would seem logical that they be given the same careful scrutiny that the microphone response of hearing aids receive.
		T coils operate by converting a magnetic field into an electrical current in the coil (the process is termed “induction”).
		According to one manufacturer of T coils (Tibbetts industry) even more progress is now being made with new concepts, such as T coils that will cancel distant electromagnetic interference without affecting performance of the desired magnetic fields (that emanating from a telephone or a loop).

		As the electrical measure of a power is always a product involving current and voltage, we may transform the character of the power by increasing or diminishing the current with a corresponding decrease or increase of the voltage.
		Variac was a trademark in the mid-20th century for a variable autotransformer intended to conveniently vary the output voltage for a steady AC input voltage.
		He did develop the Tesla coil (after Stanley's original transformer), which is a high-voltage, air-core, self-regenerative resonant transformer that generates very high voltages at high frequency (which is named in his honor).

		The two coils have approximately equal numbers of turns, although often there is a slight difference in the number of turns, in order to compensate for losses (otherwise the output voltage would be a little less than, rather than the same as, the input voltage).
		The resonant coil, usually the secondary, acts as an inductor, and is connected in series with a capacitor.
		When the primary coil is driven by a periodic source of alternating current, such as a square or Sawtooth wave at the resonant frequency, each pulse of current helps to build up an oscillation in the secondary coil.
