Uhm. Is 5,6 Kj the energy accumulated or the kinetical energy of the bullet? If it's the bullet energy then is almost the one of a bullet fired from a light rifle such as an M4 or another 5.56 cal. rifle. (with the execpion that a fire waepon can fire arount 900 riunds per minute). Good work, go on!
@zanta24 Many people believe that rail guns don't create recoil because it uses magnetism to fire (the right hand rule). One need only look to Newtons 3rd Law to know that it will. You being a person that has actually built and test fired one, can you confirm for these people that rail guns do produce recoil.
Hmm, you wrote that the projectile might puncture skin, so I reason that with 5,6 kJ you mean the energy stored in the capacitors, not the mechanical energy of the projectile.
Did you build a ballistic pendulum to measure prejectile velocity and anergy? I am curious. I built a coilgun once but found the effectivity far too low, although I used a simulation software to optimize coil and projectile.
i was just at their website but the schematic didn't show the values for the resistors R1->R6 or the cap values for the Cockroft Walton multiplier or the ratings for the diodes. does any1 know this info?
@Arb1ter The resistors are for bleeding, and are 1k each. 4 in parallel for 250 ohms. These are large power resistorts though, your normal 1/4th watt won't cut it at that resistance.
@TheKaos90 Magnets shoot the projectiles actually, a magnetic object is placed between two electromagnetic rails which fire the object along the rails using the force of magnetism. Thats basically it I think, I' sure someone will correct me if I am wrong xD
@DudeOfManyNames actually the projectile shouldnt be magnetic. the magnetic field of the rails generates force on the moving electrons in non-magnetic projectile (aluminium in most cases) and that causes the projectile to accelerate. sorry for bad english, i hope you understood what i said :D
hey quick question, what did you do to charge it? im trying to charge my caps to 300v fairly quickly but i cant seem to find anything but a camera flash circuit and that takes forever. im wondering how you charged that monster within your lifetime lol?
Hey i plan on building a railgun like this for a school project. Do you think I could make a thing like this, with limited time, money and practical knowledge?
Also, do you have schematics and stuff like that? and how much did your gun approximatly cost?
@MsMrAtze The cost is entireley variable, all depends on what capacitors you can find. A school project isn't that much time, and if you can't produce your own schemas, I don't think it is enough (the circuit really is very straightforward). Message me for more details if you do pursue it.
Hey ya this is amazing, you should try some ball bearings. And I have just one question, how do you know what way the projectile is shooting? Couldn't it go either way?
This might sound like a stupid question but would this actually hurt if you were hit with it? By hurt I mean through means of burning (melting metal is hot) but through the force of the projectile alone? It doesn't look like there is much velocity or force behind the projectiles firing.
@kkchenad Yes, it would hurt. While it doesn't compare to real guns, think of it like this: The half inch square bullet almost got through sheet steel PLUS is was hot for a couple of minutes afterwards. Skin is pretty elastic, so i don't know if it would puncture ( I would think so), but could cause internal bleeding if not.
@zanta24 well my .177 airgun can not pierce sheet steel, but goes 4-5 inches through meat (tested on chicken). That's enough to kill if it hits vitals. But yours is more powerful, so i would not point it at anything living
@kkchenad@zanta24 if 5.6kj means 5600 joules of energy for the slug, then this thing is more than lethal
In this case even if you fire a 5 gr slug, although it seems to go at a subsonic speed, a 5 gr slug should go at 1500~m/s (provided this IS a 5.6kj accelerator). E=0.5mV^2.
By the way, a colt .45 produces about 700 joules.. i just checked this on wikipedia.
@zanta24 Still enough to kill. Nice. 6% isnt all that bad really. near the efficiency of solar panels. Appreciate the comment. Dont have time to build one of my own, and dont want it to blow up in my back yard ;)
Still goes at 300+ m/2. So awesome. Need to make one eventually. merry christmas
watch ' how to make a 400v charging circuit ' to learn how to make a circuit from scratch capable of charging photo flash capacitors, you need little electronics knowledge and you only need four components.
@seabiscut251 Theoretically, yes. With enough power, you can put something like aluminum foil - which would be vaporized and propel the non-magnetic projectile.
is there any risk that the gun will blow off or electrocute me AFTER its shot?
ofc I dont plan to shoot it while im holding it, but lets say I place it over something, shoot (from the distance ofc) and then when I go to pick it up, will it throw some discharge at me or explode in my hands?
I am 17, and i made a small model coil gun running off a 12v batt, and charging up 4700uf @ 70volts, and decided Id like to scale up a tad, and ran across your vid. I have to say, thats extremely imp ressive (especially the sparks!) How many volts is your cap bank at, and how many farads is it? What do you use to charge it up to that power level? (I was just using a pulsing inductor, and siphoning off HV back EMF to charge, but wondered how others did it)
@NewPyroLabs 400v, 40 capacitors, 3900 uF. Total about 12.1 kJ (for my second version. Don't remember exactly how many capacitors was in this one.) I used a voltage tripler powered off of mains.
I'm 17 and don't know crap about this sort of thing but i would love to learn to make one of these lol. I'm planning on doing Electrical Engineering in college so maybe i will learn how someday maybe even just one to shoot ball barrings anything would be fun. I can't wait to see where railguns are at in 20-30 years. I've heard they were playing with the idea of using them as a launcher for satalites and such but i'm not sure.
@Micahj94 pftt, a college education to make one of these? I made this when I was 15-16. It isn't too terribly complicated, unless you want to go into the hardcore physics involved.
@zanta24 I understand the basic idea underwhich they work and i understand most of what you need to make one. I know how to make the electro magnet and all of that but what i don't know are the specifics of how i should store the energy. Such as if i mad a small one i would have to use a capacitor bank to store up the energy but adding to how many farads and should i use resistors. what i meant by what i don't know crap about is the details of what i said above.

What i meant by what i don't know crap about is the details of what i said above.
@Micahj94 More farads = more power. What's really required is a decent voltage to dump all that power. Even 400 is on the low end. Just get enough power that your comfortable with it and have the necessary equipment. Cost is also huge. Resistors are purely optional only for saftey. If a firing fails, then you are left with a dangerous, charged bank - and at this power level, a hards short is very dangerous, as well as damaging.
@zanta24 Ok so this is about where my knowledge level ends i knew a bit more a while ago when i did research on it but forgot a lot of it since. Thank you for the info i do still plan on making it and would if money weren't such a big factor. Maybe once i find a job and get some money i will make one. It sounds just like a cool fun project. My expertise lies more in computers than this kind of electrics. But maybe i will study this sort of thing in college it could be fun i'm just an EE person.
@Micahj94 Sorry for the second reply, but electrically, a rail gun is EXTREMLEY simple - just shorting out a power source, with a specific arrangement of wires (in essence).
@savemyplaylist You are misunderstanding my questions. Can you tell me exactly how many of what size capacitors i am going to need to design a rail gun capable of firing a 10 gram projectile at a resonable speed and how much energy those capacitors will use as well as what kind of resistors to put on it and how many of those? I doubt you can do all of that without doing some research and i much more doubt you could have done it under the age of 12.
hey, currently I am in the process on designing a railgun myself and control board. I was wondering if you wouldn't mind sharing some of your designs and knowledge. In return maybe I could share some of my designs. It could be like working together, you could call it.
Do you think it could be possible to use tungsten proyectiles? The tungsten is the metal that has the highest fusion temperature, maybe it could work¿?
@xantyleonhart It might, but would be awful. Tungsten is a poor conductor. Aluminum is a good conductor. Also, you don't want a high melting point, lower than the copper rails. That way, more damage occurs to the cheap easily replaceable projectiles, instead of the expensive rails.
did your rail gun ever punch through anything at least a 1/8 inch steal diamond plate or something equal to that.\
because a gun that size should be able to put a big dent or make it fly across the room. or at least burn a whole in it with all the plasma its making
try different projectiles with different shapes. i found huge success with a shotgun type system that had a way better conductor un a cube shape that the hardened steal spick out and through my dry wall and stopped at my bricks
@kjun13 finally someone using their brain before they post a comment damn we all know your from the future, here hit this we call it kill !! u damn right @kjun13 it would fuck some zombies HARD!! lol
@DeliciousMalicious68 I made smaller one during my first year at university in physics, but the professor demanded I destroy it because it was too dangerous.
Some of the most successful hyper-velocity railgun tests used an explosive charge timed to detonate just behind the projectile which "compressed" the magnetic flux and plasma wave resulting in extreme velocity in the projectile. Some of these tests launched sugar-cube sized projectiles all the way through steel trash cans. Google "rail gun explosive charge".
@zanta24 what's up with all the words like flux anyways? i thought i would only ever see those kinda words on STARWARS, now i hear scientists saying flux and shit but its kinda fucked up when there saying like "oh yeah the plasma burst was a crazy thing comeing from my flux compassitor."
@yungpadiwan flux means "change". Rate of change is a fundamental property when dealing with electromagnetism. That is why spinning a generator quickly will generate more electricity, the rate of magnetic field change is much higher. Current rate is di/dt, and voltage is dv/dt.
So is there any sign of a projectile after firing?, if not I would suggest boring a hole through the middle of the projectile and putting a piece of sharpened iron rod in the hole. This will not disintegrate blah blah you know.
@Ashkelion in the navy test video the reason why there is fire and sparks is because there is so much friction between the air and the projectile because of the speed it is travelling at that the air basically catches fire
It takes time to charge up the power. The charge time determines the rate of fire, which would make the gun useless for carrying use. If anything to be concealed, it would be best as a portable artillery.
I feel the best purpose for this weapon is a homeland defense for any country wanting to shoot down an enemy missile that is headed towards them with little to no warning. It can track and aim, and reach distances, I believe it can cover the Atlantic.
What kind of velocity are we talking about here? I read through your Instructables bit, and your plan seems to be the most professional and powerful . . . 5.6kJ seems respectable, although I'm planning a slightly more industrial model of your plans to have some fun with, but the specs would help. And how do your rails hold up to the stress?
@JavaMac08 Never measured this one. In all fairness, this one was crude and basically sucked. If you didn't see, I did a 12kJ one (more than twice the power), that is actually well constructed. In addition, less buss bars, wider conductors, etc for more effeciency. Not to mention saftey improvements (bleeders).
@zanta24 yeah, im doing a science project on it, any tips? oh and it is pointless to carry because it needs to be big enough and have enough power, but as an anti-aircraft gun.............
@zanta24 Actually it'd be pretty easy to find out, safely. If you have the resources to make a coilgun, I bet you can get ballistic gel too. Mold it thick enough for an average person's midsection, and fire away.
This reminds of the time me and my friends made an electromagnetic cannon using an aluminum ring and a solenoid with a displaced iron core. We eventually got a copper ring and some liquid nitrogen which improved it by a lot.
Steel wont work, it's magnetic. Both titanium and tungsten would work, but it's either the projectile melts, or the rails do, and i chose projectile. Also cheaper. In addition, aluminum is more conductive.
Would love to build a metroid style "power suit" with this built into the arm. "Why?" you say, "What would you shoot at?". Absolutely nothing but it would be fun to build, cool to play with (responsibly, of course) and make an amazing hallowe'en costume
If you put a rail gun of that power or hyer on your arm it will probobly tair the arm of as your shooting. Railguns are the most powerful weapons on earth and thay produce a emence reciol. Dont try. Or go under 1 KJ, Its safer :)
so your saying there is a instant transition between plasma temperatures to solid temperatures? There is far more liquid aluminum than plasma. The rails are coated with aluminum in areas, and I found aluminum flakes on the base after firing, much like when a drop of solder falls of a iron.
you should shout on something like wood or a phonebook that we can see how hard it shouts^^

did your rail gun ever punch through anything at least a 1/8 inch steal diamond plate or something equal to that.\
because a gun that size should be able to put a big dent or make it fly across the room. or at least burn a whole in it with all the plasma its making
try different projectiles with different shapes. i found huge success with a shotgun type system that had a way better conductor un a cube shape that the hardened steal spick out and through my dry wall and stopped at my bricks

AsianAndrew1993 1 year ago
Some of the most successful hyper-velocity railgun tests used an explosive charge timed to detonate just behind the projectile which "compressed" the magnetic flux and plasma wave resulting in extreme velocity in the projectile. Some of these tests launched sugar-cube sized projectiles all the way through steel trash cans. Google "rail gun explosive charge".
mbunds 1 year ago
@mbunds I think your thinking of a explosively pumped magnetic flux compression generator. It is a power supply, not the railgun it self.
zanta24 1 year ago
@zanta24 what's up with all the words like flux anyways? i thought i would only ever see those kinda words on STARWARS, now i hear scientists saying flux and shit but its kinda fucked up when there saying like "oh yeah the plasma burst was a crazy thing comeing from my flux compassitor."
yungpadiwan 1 year ago
@yungpadiwan flux means "change". Rate of change is a fundamental property when dealing with electromagnetism. That is why spinning a generator quickly will generate more electricity, the rate of magnetic field change is much higher. Current rate is di/dt, and voltage is dv/dt.

So is there any sign of a projectile after firing?, if not I would suggest boring a hole through the middle of the projectile and putting a piece of sharpened iron rod in the hole. This will not disintegrate blah blah you know.

@Ashkelion I am uncertain but it may be bits of the rails and such. The friction in a mag device like this is severe.
HitodamaKyrie 1 year ago
@Ashkelion in the navy test video the reason why there is fire and sparks is because there is so much friction between the air and the projectile because of the speed it is travelling at that the air basically catches fire

PrecisionEngineered 1 year ago
@TheOffspringOfMedia1
It takes time to charge up the power. The charge time determines the rate of fire, which would make the gun useless for carrying use. If anything to be concealed, it would be best as a portable artillery.
I feel the best purpose for this weapon is a homeland defense for any country wanting to shoot down an enemy missile that is headed towards them with little to no warning. It can track and aim, and reach distances, I believe it can cover the Atlantic.

What kind of velocity are we talking about here? I read through your Instructables bit, and your plan seems to be the most professional and powerful . . . 5.6kJ seems respectable, although I'm planning a slightly more industrial model of your plans to have some fun with, but the specs would help. And how do your rails hold up to the stress?
JavaMac08 1 year ago
@JavaMac08 Never measured this one. In all fairness, this one was crude and basically sucked. If you didn't see, I did a 12kJ one (more than twice the power), that is actually well constructed. In addition, less buss bars, wider conductors, etc for more effeciency. Not to mention saftey improvements (bleeders).

Steel wont work, it's magnetic. Both titanium and tungsten would work, but it's either the projectile melts, or the rails do, and i chose projectile. Also cheaper. In addition, aluminum is more conductive.

hellkid94 1 year ago
so your saying there is a instant transition between plasma temperatures to solid temperatures? There is far more liquid aluminum than plasma. The rails are coated with aluminum in areas, and I found aluminum flakes on the base after firing, much like when a drop of solder falls of a iron.
