My portable Coilgun @ 900J

[TheHappyWhaleshark]

portable? are you sure?

[FalltoAbism]

can you make a step by step toturial ?

[MrUndeadMaker]

ok kan anyone help me i have these caps form a camrea that claim to be 80joules but if dat gun in dis vid is 100joules theres is something seriously wrong cause i dont get even nearly that much power so kan anyone explain and/or post a link were i kan get some of the caps that are like da ones in dis vid

[startagain127]

that is not portable xD but well done

[seththeslayer1]

how many capacitors did you use

[HWGuyEG]

You gotta make that pump action.

[Tommo020788]

All that effort and time, to make this monster looking gun, and thats all it can put out? :(

I would have tested a smaller prototype at that voltage, then when moving onto a bigger project like that, make one with at least a 1000v capacitor :)

That would pack a decent punch!

[legomakerzy]

don't you know not to put metal in a microwave :D

[ATOMICWATERSTUDIOS]

make a tut plz plz plz and if you dont want hem to tumble in the ait make the back like of the bullet like an arros put feathers or metal wings

[vladnuke]

make it load itself, a motor could do that.

[jumpupdnbdj]

Do you know what goggles are?

[Jarek1909]

Hmm, you could use lower weight ,,projectiles", but it's not suitable for your gun.

You could have others at higher speed, and the lower and sharper is bullet, it will have better piercing abilities.

[Jarek1909]

I want to buy one :D.

Is it possible to make it more powerfull, for eg. using high power condensators, or placing more electromagnets?

It would req some more controlling of power management, electronical, but i think its possible.

What is weight of that gun?

[sundernkingz]

Das mit dem Magazin ist keine so gute idee... damit fällt die konstruktion unters Waffengesetz (und mehr als 1 Joule Output wird das teil ja auch haben)

Lass dich nit erwischen :D

Btw. wie viele Kondensatoren hast du benutzt?

[TUSpeeddy]

man , your ammo is too heavy , if you cut it at half pieces , it will gain much more speed

[TheePlaceboEffect]

Sick :o

[TheJohniWalker]

Was für kondensatoren hast du gebraucht? Und wie teuer waren sie?

[szuszi2]

hi! can u make the pipe out of copper or any kind of metal?

thanks

[TheShiningDragon]

Where are you find so big capacitors?

[freitasnetuno]

Why the hell you guys insists in using MONSTER SIZE projectiles???

[TeslaCoilArbiter]

@freitasnetuno

using larger projectiles will give you a larger mass to surface area so you may have more attraction between the coil and the projectile..maybe..i guess, so you get a faster muzzle velocity. somebody state otherwise if im wrong.

[freitasnetuno]

@TeslaCoilArbiter larger mass = larger weight, wich requires much more powerful coils, i really think big projectiles (on this early stages of development) is a bad idea.

[Timmaebo]

Welche Ladeschaltung hast du benutzt? (BoostConverter??)

[NickelxK5]

I would really like to learn how to create my own. I have looked into it, but im unsure as to what component does what. I see that caps are measured in Volts and uF's. Could someone explain what makes it more powerful. And if I were to have a cap bank of 4 capacitors each with 200V would that be 800V? And also I don't understand what a charging bank is either. So if anyone knows of a good place to learn all of this could you show me.

[bubbabrit31]

@NickelxK5 check out a physic's textbook with an extensive material on the properties of electricity, there's plenty of formulas to convert joules to amperage versus the amount of power you're losing do to the resistance in the wires, ultimately just read up a shitload and use a switch that's resistant enough to not melt every shot you fire

[TeslaCoilArbiter]

@NickelxK5

it depends, generally you want to stick them in parallel which will mean you add all of the microFarad (uF) readings together but keep the voltage readings the same. eg you have five capacitors rated 350 volts and 2,000uF each, it will equal 10,000uf at 350 volts

[MetrakitProRaceII]

Sehr schön aufgebaut !

Genau , löcher den Conrad :D Eh viel zu teuer da !

[LeftoverJedi]

Nice work man, awesome. And thats just with household materiels, imagine what a factory version could do

[NHScullcrusher]

TEST

[KileSimons]

SCIENCE!!

[lisn92]

has any one tried putting some low amp fuse wire on the back and front of the projectiles and have a little catch that puts some power to the fuse wire to burn it off so that when the front projectile moves forward it will bring the one from the back to the front, so no need to reload

[Smeeshly]

lmao yeah a little bit close with the lame there

[horusai]

nett :D gehste jetze campen oda was? XD

[RudiMedia]

Nettes Teil! Nur schade das dein Video kein Ton mehr hat...

Welches CAD Programm hast du den zur Konstruktion verwendet?

[TheQuantumChemist]

Good Gun ill upload mine soon. woah woah woah at 3:53 you are using that flame way to close to the bottle and gas line

[wyz2285]

it is still big..but nice

[7410n0]

bloody thumb D:

[xollst]

dude that thing is lethal haha

is it possible to rifle the barrel so you get some stability, then you can shoot at range and not have the thing toppling end over end

[familyfreaks1]

it,s a bit BIGi still if it didnt fire you could beat them to death with it

[nmexxx]

bin atm auch grade am coil gun basteln:

2 stages: 1. 3700uf/400v 2. 1800uf/400v

mich würde vorallem deine verwendeten thyristoren interresieren denn ich weiß nicht so richtig wie groß ich sie dimensionieren soll^^

[super6plx]

GOD DAMN I want one of those!

it makes me want to make one xD but I know I'll never have one as good as that beast

[kosec321]

would you explane how a schematic would look like ? :S

[MarcusDarling4026]

Hmm- I suppose that a vampire slayer would use wood tipped projectiles & use silver for werewolves.

Abraham Van Helsing would LOVE this weapon! lol

You should link up with that kid, on here, that has mastered rapid- fire system, for his coil gun!

[MW4RD]

at 0:48 are they sparking gaps? and mains power, thats spaz! sweet job dude

[PhoenixCola]

No, they are SCR Thyristors, solid state silicon devices used for switching high amounts of power. The ones in the video are connected in parallel in order to handle huge power delivered from capacitors into coils. They are electricaly operated through gate leads.

[realyoyoweb]

How many µF ?! and the voltage ?

[jsamout]

5UCK MY D1CK @ 1:35 :D

[suzuki834]

u have no friends i bet

but u can make cool shit abviously

[727Dexter]

yesterday were no probs

[SunTzuLao]

Fuck WMG

[gonepishing]

cool but its only single stage =P

looks like the halo gun :D

[thelonewolf267]

what the fuck, ket me hear audio. its just a damn vid!

[harddiskfragger]

wtf

[MrKaine777]

amazing. this was made 2 years ago, what are you making now?

[mrfrankincense]

if you could build a one firing the bullet portion of a real round that would be great!

[nullproperty]

looks like somebody hammered their thumb! =] :P

[laser5890]

300j

[mellon423]

FUCK THE WMG

[hiforeverhi]

This is awesome! What is the farthest possible range on this gun and how much does it weigh?

[Metadaxe]

900J can't penetrate a phone book?

[brandonsg123]

lol when u wer cutting the wood ur foot was rite in the line of fire from the sparks didnt that hurt?

[phnixjem]

will you put plans of this on youtube? this is one of the better guns i have seen. i have not built a coil gun before and i would like to build this one.

[eightball20055]

epic

[fpsgene]

I'm not one to tell you any tips, but I'm so impressed. I really want to make my own, but I have no experience or materials, I think. But I do know aerodynamics. If you can get your hands on a 7.62 round or a 5.56, or even a diagram, you should try to shape your rounds like that. Even though you have sharp points, it's angle is small, so it's practically blunt. More over, try tempering a little more or the round, it'll give better penetration; as well, like someone said, shorten the rounds.

[SP3C1A1]

adding on to this... when you'r hardening the tip of your round you need to add carbon to it or all it's doing is changing color.. you can buy surface hardener in powder form (the safest way)or you can heat the projectile till it glows red and submerge it in used motor oil (not synthetic) this WILL cause a fire, DO NOT DO THIS IN YOUR BASEMENT. use a small pot with a lid to smother the fire

[quellenathanar]

The back yard scientist does this for fun, but the concept of coil/rail guns scaled up with much more power/more coils assisting in sending a heavy payload into orbit. Imagine eliminating 80% of fuel/weight of such launches by taking the massive burden of 0-3000 MPH velocity off of the space craft, and allowing the railgun on the ground to do the work.

As for weaponizing.. It's only viable currently for large weapons. Sadly gun powder is a lot more efficient. We need to dev better batt/caps.

[WolfVecho]

awesome design

well done

[jjwoznia]

You should try shorter rounds. It would make your muzzle velocity much higher, at the cost of impact "weight." But a sharper and faster round will pass through that can much easier. Too short and you'll start having bouncers which is no good.

[mykelittle]

look an oversized nail gun! 8^D) Try to roof a house with this bad boy! lol j/k nice weapon man. Keep workin on that hiding the wire issue and making it more portable! Nice job!

[greenhorse176]

that is some crazy ass shit but not as fast as some coil guns ive seen

[RoteKampfSocke]

Probiers mal mit nem kleineren Kaliber und vorallem leichteren projektilen.

Mit nem getriebemotor und nem pleuel kannst du nen halbautomaten draus machen!

sehr intressantes projekt!

[123IOWNALL321]

Great weapon! I'd hardly call it portable, though :\.

I agree that it's possible that the Military can adapt these (since you know them, always improving things) although it would be nice if they DIDN'T get their hands on them. The more power the people have, the better >:)

[ThompZon]

Nice one!

Now let's make a multi coiled prototype with 900J/coil XD

Too bad that the link in the end of the vid isn't worikng anymore...

[0redthunder0]

Were you heat treating the tips?:O that looked well cool!

[gr8lady]

that reminds me of BFG of Doom, I have to make one my own >:)

[mowpow999]

holy shit, i am really into guns and the evolution of modern wepons and this would have too be one of the most inturesting and cool ass things i have ever seen

[highclazzz]

OMG! What a Nerd But the gun is cool :P

[Maverick24340]

wow thats a good coil gun my one is similar but the bullets are smaller and they have a velocity of about 100m/s.

[cleavage33]

see i dont understand all this rocket science shit all i wanna no if its so good then why haven't they military adopted the tech for future weapons

[NickBlackDIN]

do you see how clunky that thing is?

nah, coil (guns) are great for the lab, especially considering you can get the exact same velocity every time and such (gunpowder and other chemicals always burn slightly different) but out on a battle field, it's way to much unnecessary weight and complexity.

[iunnox666]

Plus tradition guns are much more powerful with less weight and size, but eventually they may be better.

[WatchRyder]

A shame but true.

The Capacitors take time to charge as well and I think that Airguns are of a similar power.

But its possible that the technology will improve so these results are promising

[ninjafred13]

fucking awesome dude. 5/5stars

[saphirekosmos]

Awsome.Nice work.

[cameronlorankey]

how much will you build me one for?

[faceheadman]

that thing is badass!!

[fabs0r1]

sehr geile sache das. hochachtung für den erreichten wirkungsgrad, auch wenn rechnerisch noch bissi mehr drin wär ;)

mfg, ein student der e-technik

[Tonitzi91]

In end of your video: 0.5x0.04x(90m/s)`2= over 100Joules

[FunkenStreckenBrater]

I reached the 90m/s with a piece of a thick steel wire (2,5 mm or so) with a weight of under 5 gramms.

The normal sawn off nails you see in the vid have a weight of 40 gramms and fly many times slower.

[filipake80]

@FunkenStreckenBrater za ile pieniędzy to zrobileś

poland

[Tonitzi91]

The muzzle velocity cant be that high, over 100 joules for that bullet would go trough the that book easily:)

[FunkenStreckenBrater]

What? Again, where did you read this stuf with the 100J?

I said, that the bolt weight is about 40 g or so, thats a fact.

With a very light and thin piece of a steel rod I reached something about 90 m/s or so (couldnt meassure it accuratly because the very small diameter). Thats also a fact.

The electrical energy stored in the capacitors is 900J max.

But where I said something about 100J kinetic Energy?

[xato909]

é isso mesmo conceguistes parabéns!!!!!!!1

[ChemistN1]

175joules o_O

it is more powerfull than any bb-gun

[FunkenStreckenBrater]

Its not nearly that powerful, where did you find this?

[ChemistN1]

As I know bb-gun's energy doesn't reach 150 joules.

[FunkenStreckenBrater]

I mean my Coilgun, it cant reach a muzzle energy even nearly that high.

[303britishrocks]

Exactly. I have a coilgun with capacitors that are at 2.9kj but i can tell you the muzzle energy is nowhere near that.

[fdsman]

man blued tips are going to last a long time.

[robotwo]

oooh , you got some nasty damage on your left thumb :B , nice gun *thumbs up*

[nemanume]

pls tell me the name of the song ...

[clownboxer5150]

Cashews....the most vile of all nuts. Kill them all. You are my hero!

[poupoutime24]

U could add a small lazer pointer at the end of the canon 4 more acuracy, i think 8-) !

[emuman4evr]

Can I have your 4-6 second charging circuit?

[comepost]

no its Bang Bang

[comepost]

no you where right sorry xD

[aroguegurklis]

I like the fact that you designed it to use a magazine with a straight pull bolt action. Considering that this is probably only a rough prototype, it looks like it's gonna be great farther down the line. Good work.

[nitrogeb]

you have to use small ammo,like a 0.22 or 0.177.

with those ammo you can kill a pidgeon....

[Mingebagz1]

I have an idea, Compact its size by, number one. putting them Ohm measurer (I believe thats the yellow thing.) And all the other display electronics in a little block on your side of your ventilation piece, and number two putting all other electronics in the butt stock, and three if possible use a car battery, or a bunch of lithium in batteries (Be careful they can explode.) Thanks for your time.

[Demonj27]

Now to make it automatic...?

[MadGouki]

wow, that thing is way too big for packing such a small punch.

[TatsuZZmage]

nice gun, im thinking of trying something like it using dispose. camera caps and old networking cable for the coil i doubt ill get any performance like yours but what the hell.

[piaga123]

Lol the nail!

[Meddlmoe]

übrigens. Nägel bestehen aus stark kaltverformten stahl. dadurch dass du die spitze erwärmst wird sie nur weicher, selbst wenn du sie danach abgeschreckt hättest, dann wären sie immernoch weicher, ausser du bemühst dich um einen sehr aufwändigen prozess.

[Meddlmoe]

Ha Ha! the police picked it up^^

[Slider795]

is that thing connected to mains power? (looks like it)

maybee you should focus on fast discharge capacitors not those masive ones your've got

just wire series or parralel many smaller fast capacitors

And what switching device you got anyway?

maybee chuck a IGBT in there faster coil discharge = more power

[Sth375]

What happened to ur thumb when u was loading ur ammo?

[yagduse]

ich bin beeindruckt,well done buddy;) ich hätte ne frage,und zwar wenn man eine coilgun bauen würde welche man an eine normale externe stromquelle ,zum beispiel steckdose,anschließt,wäre dann die austriitsgeschwindigkeit der projektile wesentlich höher???

[FunkenStreckenBrater]

Ne Coilgun benutzt Kondensatoren, so dass mehrere kA fleießen können, mit 16 oder auch 64 A ausser Dose kommt man nicht weit ;)

[Arthurein]

what are the songs of the video?

[driftspecmotorsports]

amazing work man...congrats on designing and assembling such a peace of machinery.

u from europe by any chance?

[mnymatt]

dam for such a big and high teck looking gun why is it so weak.... no disrespect i just want to know because it has all those wires and its like a bb gun i was expecting it to demolish everything it hit good job though

[FunkenStreckenBrater]

Lets name it a veeery early prototype ;)

[ChemistN1]

175joules o_O

it is more powerfull than any bb-gun

[buchnermarkus]

I know the song is from lord of war. But whats its name?

[FunkenStreckenBrater]

one which?

[buchnermarkus]

I mean the very first song.

[Floodedgunner]

lol even in the slow-mo you can barely make out how fast those things are moving. This is highly impressive, I wish I had the time and resources to do this. The next thing you should work on is making it portable. and a bit more ergonomical, lol. Also, does it have recoil? Thumbs-up all the way though.

Glückwünsche, und viel Glück! (That was my attempt at German lol)

[wayne205stevens]

Kickass nail gun!! :)

[fuckinginsane]

looool!! DIE Conrad Box DIEE!!

[captainhero2]

excellent work, I was wondering, how accurate is it, as in, if the gun was stationary, would it hit the same spot every time? Also, could you put two sets of charges that alternate, one charging while you fire off the other one? I liked the clip you made, do you think its possible to make an automatic loader, maybe using some of the magnetic force to activate a mechanism that either pushes or pulls the next bolt into place? BTW- I liked the gun design.

[Aqlor]

Jesus! How much did that cost you?How much time did it take to make?

[mychemicalromance811]

That gun is SERIOUSLY badass.

[Halo2maniaccc]

Nice gun, but i wouldn't call this portable! More like movable. I really want to see someone make a coilgun but make the cap unit in a backpack so the gun can be light.

[m3ky2k]

its as portable as a rocketlauncher :o

[kongman74]

Sehr gut! Einer elektrischer gewehr aufgemacht in seiner Hause!

[maxter357]

you PORTABLE coilgun huh? xD

just jokin...

awsum job!

[injunjoe390]

This is freaking amazing, you should ramp up the power and bring it to a real range

[cutsgems]

Excellent job. Hope you get the opportunity to have access to real machine tools one day, you could do wonders with a lathe & mill. You've got a good future, study physics and keep up the good work.

[enderwood]

I love it.

Nice project. :)

[Ryotsutsu]

LOL nice shirt "suck my dick"

[alexbmwm7]

dude some thing is fucked up in your maind but it so cool i want one to

[dafyddoe]

ingenious.

[Darthak223]

Wow. That looks extremley dangerous. Where can I get one?!?

[Kojema]

Yeah.. that thing is totally portable. [/sarcasm]

[ircluzar]

you are dangerous.

i hope you get arrested.

[FunkenStreckenBrater]

Poeple with an IQ of under 70 like you are dangerous and need to get some education or simply medicamentosum Treatment...

unbelievable

[FunkenStreckenBrater]

By the way, look at the first vid on the page of this guy...omg

he have to had a hard childhood, sad ;)

[Twister60]

wear some gloves kid

[ABSOLUTcalan]

Wo kann man sich das bestellen?^^

[SkullHunter00]

Nice man!! The coil rifle doesn't look bad, it works well and it shoots, and shoots even better with Rammstein playing!

[Mohruebi]

Genial. Gefällt mir.

[dhruv010]

dude thts fucking awsome!!!! can u send me the plans for it...id love to make 1...thnx!!

[mactep4eef70]

Man, you great!!!

[xPR3CiSiONx]

Awesome bolt action. I would have failed miserbly attempting that. I'm thinking about building one myself, just regular though, not anyhtin like that.

[haggywitch]

that is a huge gauss rifle can you even hold it completely horizontal while standing? It looks like you worked really hard on it, nice job. I made a coil pistol, u can make the charge from the capacitors add up by doing a paralell circuit, it gives A LOT more power.

[embalmer214]

You should try a ball bearing nice round metal.

The plans are in this months nuts and volts mag.

It also explains how to increase the caps and coils to raise the volts to increase the volocity of the round.

[webdoggboy]

wie war nochmal die formel for die joule der kondis?

[FunkenStreckenBrater]

E=1/2*U²*C

[webdoggboy]

wie rechnet man das?

bin erst in der 7. aber klassenbester in mathe und physik da ich mich mit sowas beschäfftige allerdings im gymnasium^^

[FunkenStreckenBrater]

Energie= 1/2 * Spannung hoch2 mal Kapazität in Farad

Mehr kann ich dir jetzt hier im comment schlecht erklären, wenn was nicht klar ist, frag mal deine Physiklehrer, vllt. nach ner Herleitung der Formel, Wikipedia ist da immer ein wenig ungünstig weil schlecht erklärt...

[webdoggboy]

ok danke alles klar ich habs jetzt verstanden

thx!!!

[T55TankR]

WOW that's an impressive rifle!!! I want to make one for myself and I want to ask that is this expensive or not... as for the vid I really enjoyed watching it :D You did a great job. Next time you should make an outdoor vid. and try shooting (of course with more stabilized projectiles) for 20m because as I can see it has the power

[FunkenStreckenBrater]

Its not that expensive, you just need some luck at Ebay and some junkjards, I think 100 would be more than enought for a really good and big cg.

[T55TankR]

Thx. And how much is the weight of a gun like that in kg-s? Looks heavy but very nice design ;) It's similar to the one in Starship Troopers in some way :D ... Coool

[FunkenStreckenBrater]

it ways just a bit over 9 kg, way to heavy.

[FunkenStreckenBrater]

I dont know if it could kill someone, I will never try it out;) You can compare it to a common crossbow.

Well, the range is not thet impressive, because the bolt is relativly slow in comparison to its weight and not stabilisated by rotation, so it flys in a very inaccurate and uncontrolled way on larger ranges. Its capable to make it stick into a phone bick at max. 10 m or so, then its nearly impossible to hit anything with the sharp end and not with the side, so its not that strong.

[southwest82]

Do you speak Klingon per chance..... no, real good job, I about blew myself up last time I tried to make one, seems that old caps found in the dumpster are in there for a reason LOL!

[beanmaster]

[sarcasm]Thats what i call portable[/sarcasm]

[Yofacestank]

Now, all you need is silver stakes instead of nails and you can hunt some vampires and werewolves.

[nedelkov1234]

is the weight of the projectiles optimal?

make it smaller but sharper. but again im new at this how much surface area projectile is used as a core

[dmsanct]

but the capacitator is 900j, even tho its powerful it would be 10 times harder to make a coil gun that can actually shoot an object at 1600 joule xD

[VicariousReality7]

Those shots maybe hits with ONE joule.

What do you mean 900?

That's about as a .357 Magnum!

[MisterPie1]

Are you stupid? A 357 would be about 900 KILOjoules... And a single joule would be like someone poking you...

[VicariousReality7]

CHECK THE WIKIPEDIA ARTICLE!

My BSA Meteor air rifle shoots with 10 joules.

[dmsanct]

yep his right, a deagle is about 1500 joules

[explosive2121]

cool, but it needs more power in the gun

[P0TiKOUTLAW]

lol guys have way to much time on your hands or your just smart compard to most you make it look easy or supper hard

[b0l4ch4]

What the music 2:20?
