3. EM-15 coil gun
The EM-15 is a gun that the military could get lots of use from if it ever goes into production.
“The EM-15 coil gun is a handheld, battery powered (12 VDC) rifle that is capable of launching a .30 caliber metallic projectile at adjustable velocities. The electronic circuit consists of a voltage step-up transformer converter, a Cockcroft-Walton voltage multiplier cascade, a capacitor energy storage bank, a voltage comparator to set the charge voltage on the capacitor bank, an SCR switching section and a single accelerator coil. Other components of the gun are the barrel, breech loading mechanism, battery supply, capacitor bank, control panel, display, projectile, pistol grip with trigger assembly and an aluminum stock that contains all of the components.”

The military won’t use those for a very long time. The standard rifle has a handful of parts that a evan a third world country can produce at some reduction of fit and finish (though some of British Indias are beautiful) they will work.
A coil has how many parts? And can you make those parts in your basement? How reliable is it? Will it equal the performance of a military rifle? Can you fire 30 rounds with 300 yard accuracy of 2MOA and a terminal energy equal to a 5.56 Nato?
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.
It’s just the way they are, too many scams, false promises, too many small arms ‘already made up and ready to go’ for them to not be wary of a new ‘gee whiz’ non-strategic, non-theater weapons system. If a peer competitor comes along that has drastically improved solder protection systems against small arms fire they might be pushed into it but that’s no looking likely just now and they can always choose the less expensive option of bumping the caliber up a notch or three.

Remember when the M16 was first made?… the military hated it, and now look at what it has become. coil guns have just as much a chance of becoming a completely standardized weapon system as any other prototype or experimental weapons out there. not to say your a nut though, your not. and the velocity of a 5.56 Nato round can be matched by this type of technology, and with pinpoint accuracy. this is basically a hand held rail gun of sorts. this also in my mind (when scaled up) would make a great artillery weapon.

the new design for the nuclear liberty ships is seriously considering the benefits of a “propelantless” weapons system, aka coil gun. the abillity to store two to three times as much ammo on a ship is a really big perk.
in addition, a variant of the CIWS (close in weapons system, the Gatling guns used to defeat incoming missiles) is being considered for Naval warfare. a version is in the works for tanks, but i believe that it uses centripetal force to launch the projectile.
the military is taking a serious look at these systems, and if we can find a safe way to store more energy (or produce it) in the same space as the propellant of current arms, then i believe the military would switch over in an instant. the silent aspect alone is a great selling point.
so, even though we’re not using them yet, i’m sure that at some point they will be.

Was that jock powder he was shooting at?
January 28th, 2007
There is no muzzle flash either so that also adds to it in more of a stealth aspect.
January 28th, 2007
Plus there is minimal ammounts of noise, compared to the explosives in conventional ammo === more death less noise pollution. Clearly a great benefit to all. Also the guy shooting the em-15 was a total goober as was that cheesy music, no offense

Tough crowd. Whether it will be weaponized remains to be seen. Right now its just a guy having fun. I think we can all appreciate fun can’t we? I sure can.

[…] 6 - Top 5 Coil Guns “Here is a list of 5 cool coil guns, either one would be fun to try out.” Erm, yes … though it *is* quite cool to see sf-nal weapons can be made in one’s garage. The Mundane SF folks should take note, perhaps? (tags: manufacture garage DIY hacks weapon rail propulsion magnetic guns coil) […]

Coilguns are indeed a bit too complicated and use too much energy for a practical handweapon. But if you’d place it on a big ship, then the energy use and complexity arent that much of a problem anymore.
Imagine a 20cm caliber monster that lobs semi-smart warheads miles and miles inland. With multiple huge capacitors that are charged and fired one-by-one for high fire-rate, all powered by something like a turbine engine (or a nuclear plant maybe.. massive!). Or maybe a dual-barrel..
Would be great for shore bombardment, and probably way cheaper per-shot then (cruise)missiles or a JDAM delivery.

There are many parts to these now, but in production they would be like an automobile dash- simplified for mass production and unitized for space/size. They have the many pluses above including no igniteable material, very simplified and safe storage, one could carry many more projectiles, and they are relatively silent. Cyclic rate would depend on recharge rate as would charge life. Of course one can easily say the prototypes are all using electronics designed for other purposes and as prototypes are crude and impractical. Any production model, regardless of projectile size, would be very much lighter, more streamlined and easier to use. And as pointed out already, the projectiles would be much cheaper than those used now for artillery. The near future will probably give us appropriate energy sources, such as nano-tube based capacitors capable of storing enormous energy and rapid cycling. These are quite impractical now, but check in on these from time to time…
March 31st, 2007
General comment on noise levels: a good fraction of the noise any weapon makes, regardless of the energy source, is the sonic boom caused by the projectile. 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.
As a selling point for coil guns, a variable muzzle velocity, set to just sub-sonic, could make for a very quiet assassination weapon. The people that are interested in such activities are probably less concerned about cost than the bulk of the military.
Looks like fun to me!

Damn! I could use that semi-automatic! (Not really, but it’d fun
)
April 10th, 2007
Wow, some of these look like they should be in some sci fi movie.
April 26th, 2007
Like it a great del, but the problem, from a military standpoint,
remains the same:
Any piece of ordnance must be reliable and effective under various
conditions, obviously. But, what happens if and when the soldier
finds himself in a hostile environment for an extended period of
time, and cannot charge the power supply for the weapon, what is he
to do? To carry it will slow him down in any attempt to escape and
evade capture, yet to leave the weapon behind, gives the enemy the
potential to recharge and use the weapon against it’s previous owner.
So the weapon must be destroyed beyond the capacity to re-engineer or
reuse, leaving the soldier without a primary weapon.

man that black one is sweet with the fire light, being semi auto, and not looking like a mass of wires

by the way i mean’t the ecg one

Who sais soldier can´t take it ? Batteries nowadays are more powerful than ever, and with special - high current/small size can be used. Why battery can´t be reloaded with magazine ? Yes, it will probably need more money, but still it is chance here. It is also good-lookin for sniper guns - one shot/one kill
but probably when sniper will need it most, still he can use normal weapon…
I think that will never be used in portable guns, it ich much expensive. But when need silence or other demands, it can be still as powerful as normal weapon.
May 13th, 2007
what about the cahce of battery fires, not very stealthy if your on fire huh?

You can be surprised what can high power batteries (meant in laboratories etc.) do ! and if CG can be more setted for lower power input, you dont need hi-power bat.

Yeah, great page

Some of these can be made with a few disposable cameras. I have made one, taking the whole charging/flash unit from one camera, and the capacitors from some more cameras. Just ire the capacitors in series, and you can add an extra battery for faster charging. Replace the flash with the coil, and fit it all into a nice little package. I have made one with a pen barrel and it shoots metal bb bullets. One of my friends broke a window with it. Cheap, and VERY effective. So stop complaining about low power, high prices, or too much wires. Just go to some photo processing center, and if they are nice, they will give you some empty disposable cameras that they throw away anyways. It is the cheapest way to make a very high powered coilgun.
July 8th, 2007
It is old, bud havent you mounted it on robowalker (or what name has that robot toy) ? And I think that wiring condensators parallell you can got better performance than with serial… only if you dont have too much voltage for capacitor…
I dont complaining…

Something bad happens - When I was shooting for “first recharge” , everything was going perfect, I loaded caps with 206V, And when I smacked trigger, Flash, Spark and smoke appeared. I don´t know what is it now, Maybe Diode, some cable or coil. But smoked it out, projectile didn´t managed to target (is still laying on ground maybe 2 metres from coilgun). Damn… But I got photos of loading it with 206V :).
Whatever, i must wait when it will be completely self-discharged (maybe week-two) because I cant work with loaded charging circuit (it is charged to 206V and it don´t have discharging circuit)…
Damn.
But maybe it is for that, because I was rebuilding it to higher voltage (I was using 195V and nothing happens). I dont know what will be next, for now, project is closed. (I am now working on smaller 400V coilgun, which skeleton can be seen on first photos, so no smacking of time (but still :C )

Are these things legal where u guys are? Im from Australia and we tend to have strict gun laws which would probably make these illegal, you have to have a basic license to own a damn airgun!
July 10th, 2007
If this is illegal (mine) , so gumgun (or how it is spelled, gun from vooden “V” and gum on it
-send this to wikipedia SMILE) is also as illegal as this mine isn´t dangerously that gumgun

If you used just the energy wave would it knock out car electronics?
July 26th, 2007
No, it must be very strong pulse (something like EMP guns), so it can induct to circuits and short it out. You can´t get that strong pulse in home, only in labs. But if you can aim this only to one device, theoreticcally it can be done. I dunno. But for whole car it is waste of time to try it.
August 10th, 2007
Could this stun someone and why is it that i have yet to see this in any military development…
I enjoy being a civvilian
August 20th, 2007
it probably could stun somebody….it could probably kill somebody , with a sharp projectile….And no, you could’t use a coil gun as an EMP device, even though the magnetic field is strong enough to accelerate the projectile inside the coil, the fiel outside the coil is too weak to disable any EM field ….it wouldn’t even damage a wristwatch 2 inches from the coil…though u could just shoot at it and break it :))
August 28th, 2007
my point is to put it simply does the military know about this so far there doing something stupid starting something big then trying to shrink it seriously
September 12th, 2007
It will be interesting to see what happens in coil gun design when tiny, super high energy density carbon nanotube based capacitors become available. I have not heard of any great leaps in inductor theory, but it could happen with more exotic materials technology. The military coilgun may well be closer to reality than most people think.
October 8th, 2007
The first time i saw such a gun was in the movie “Eraser” and thats several years ago. At that point i thought its Sci-Fi. Now years and years ago i see it again and can’t believe it. Maybe a next winter project.
November 9th, 2007
Could some send me the parts list and insturctions on how to build one. Please send it to finecoded@yahoo.com
December 23rd, 2007
i’m curious if the gun has any kick back, because if it doesn’t
that could be a major selling point for a semi auto rifle.
though if these go into mass production, all someone has to do is
make EMP weapons to counteract it. i mean think about having to
scrap an entire cannon from a battleship to rewire it. i’m not
saying it will be expensive so much as not very time effective.
or on the battle field having your rifle be out of comission when
you need it most.
sorry about the rant, though i do hope to see this technology improve.
December 26th, 2007
Parts and all things about coilguns can be seen on wikipedia
just search it out
Spoonylegs: I think it has blowback, it must (physics laws) but it would be great if someone could develop and sell this things, of course with all laws right. Still it will be long thine until that happen.
January 3rd, 2008
i’m thinking it wouldn’t have a kick back because it doesn’t have a
powder charge, or hammer to cause a kick. besides as far as i know
electrical fields are not affected by gravity, but can affect an
object in gravity (hopefully that makes sense). though now that you
mention it it could be after the projectile has left the barrel,
that the weight of the gun changing could cause the gun to swing
slightly off target. oh well at least the guns environmentally sound.
lol!
January 8th, 2008
i think that coilgun circuitry can be protected using a faraday cage(wiki it) this is alreadyused in mobile phones and planes and other electronics
the problem is… it needs to be grounded
January 28th, 2008
The real secret and potential of electromagnetically propelled projectiles over chemical ones is that they have the potential to reach hypersonic velocities, whereas you can only shoot a bullet so fast with Gunpowder (think about it, one bang and thats it, vs a long barrell with nanosecond timed current surges as the bullet accelerates).
January 28th, 2008
Yeah, that is true, but also you must remember on price
But it is creative idea to be done
January 29th, 2008
It would have a kick…. for every reaction there is a equal an opposite reaction, the bullet doesn’t want to move because of inertia, once its moving it doesn’t want to stop for the same reason. Any force used to push anything in any direction will have a certain amount of push back, and the hammer (there is no hammer anyway its a firing pin) in a conventional gun contributes nothing to the recoil. Plus as long as your m-16 isn’t on 3 round burst and you have the proper grip on it, you will barely notice the kick, let alone allow it to throw you off target. At 300 yards the hardest part of hitting your target is seeing it, not if the kick will throw you off
February 1st, 2008
i think nobody will shot CG on 300 yards in hand
so if it will be mounted on something, it should have electronical aim, or precise optical aim
