Daniel Eindhoven sent in his latest creation, this is one killer looking coil gun! The laser effects are fantastic. If you love coil guns make sure you have a look at our top 5 coil gun list.
"Fully semi-automatic, up to 14 shots.
Capable of delivering over 18J kinetic energy, and speeds up to 110km/h! (42 gram projectiles).
It’s a single stage gun, using a 8800uF(4×2200) capacitor bank with max 400v (704J).
Max shot efficiency is 2.8% but reaches almost 4% at lower voltages.
Charge time for 300v (12J kinetic energy 396J capacitor bank) is 8 seconds for the mains connection,
and when using the internal batteries about 90 seconds. It also has a Digital voltage display.
Coil overheat after 14 shots at 300v.
Total weight: 5 kilogram.
Total spend: ~~ 100 Euro
Construction time: ~~40 Hrs"
The bulb is used as charging resistor for the capacitor bank when using the mains connection. the higher wattage, the faster it charges. the problem with charging resistors is that they will dissipate a lot of energy, at this way it is safely dissipated which means less heat inside the gun.
maybe it’s not the best solution, but it was the easiest.

So 110Km/H sounds pretty fast but that really comes out to app. 96 feet per second - which is pretty low muzzle velocity — which means my boss would have no good excuse for me not to have one at work!
As Scott pointed out, a muzzle velocity of 96feet/second is slow. Paintball guns can easily do 300feet/second. Of course, the payload in this case is likely much heavier than a paintball. Releasing plans for this project may help make it more efficient and thus more deadly. Yay!
I actually calculated that. the weight of an avg paintball is 3.2 grams, when you accelerate this to 300 fps it will hold about 12.8 Joule of kinetic energy (and absorb almost all by breaking on impact).
now take 42 grams to 96 fps… over 18 Joule kinetic energy.
so it goes not that fast, but imagine the bruise it’ll get ya:)

Interesting! I came up with a similar solution when I built a quick and dirty power supply for some laser tubes out of a couple of junk microwaves. I stuck a 75W black light in as a resistor and it worked great.

Me and a buddy talked about making one in high school but even if had had the money I don’t think it would have happened. Well done.
An idea: could you use the trigger to move the bolt forward and out from under the weight of the other bolts be for firing. Something like half the trigger pull being ratcheted and just to move to bolt forward?
well my measurements indicated that it doesn’t really make much difference when the clip is full or almost empty, so I think that ill just keep it this way:) also the bullets won’t fall out this way when pointing at the ground.
Impressive.
Would indeed be interesting to see a multi-coil version of this.
A question is if it not would be more “economical” energy wise to have a mechanical first step, as a hammer, to overcome the initial inertia and friction?
Do you have had any problem with that the coil tries to decelerate the projectile after passing the coil?
yes i had that problem with higher capacity (more capacitors). our basic version had 18 of them and the projectile actually came out the same way it got in, and fast!
i think it would be a little more economical if you would use a normal electromagnet actuator for the first punch. but then you need an optoelectric triggermechanism for the first stage. that would be to much trouble for a 1 stage gun. but if youre going multistage anyways i would certainly do that.
I just wanted to let you know that I think your homemade electricity gun is awesome!!!! Looks like you are having a really fun time with that hobby. I’m looking forward to seeing more of your creations.

All that needs to be done now, is use higher capacitance capacitors and rifle the rounds. But no matter what, a coilgun will never be all that powerful due to magnetic saturation (unless you want to talk about quench guns). Rail guns are far more promising, although keeping the rails from fusing can be hard.
@mary, and clearly some have to much time to compare a build with their old bb guns.
let this guy alone, he build something cool and awsome. what have you done the last few weeks? All this comparisons to a bb gun. thats totally lame. he didnt want to build a killing device i persume. he build a coil gun, that works. Do you have one? You know how to get is better and more killing? DO IT! not just complaining about how weak this is…. till than stfu
I don’t think rifling this would bring much benefit. The velocity is too low already. Increase the power? Increase the number of coils. Add a second coil in the middle of the gun. Then the real problem would be timing the second to fire at just the right time. I would like to try that.
dutch, aren’t you?
mooie gun! en dat in een week tijd!
mijne wordt backback style: lichte gun, dikke kabel naar een rugzak met 4 x 4700uF @ 380V.
maar mijne heeft geen auto-reload. grendelgeweer, zes kogels in een clip.
ik zit erover te denken ook zoiets te doen, maar dan wel semi automatisch met spijkers ofzo. ik heb nog 6 thyristors liggen dus ik denk dat ik maar gelijk voor 6 stage ga;) maargoed eerst nog maar wat onderdelen verzamelen.
Would it not be possible to stack charges for more than one bolt. Allow for more time on the initial charge up time, holding charge for say 3 bolts, then whilst the first 3 bolts are fired the charge up cycle begins?
becouse the current to the coil is so high no ordenary switch can hanle it, also a lot of energy would go to waste to heat and arcing. thats why a silicon controlled rectifier (scr, thyristor) is used.
Good base for future improvement and possible militaristic use, but i could throw a metal projectile more forcefully than your current model. Needs improvement but good start!
I was just thinking, why are you bullets so large? Looks like you copied the size of a real bullet and cartridge. Smaller bullet = higher velocity = higher accuracy. Use the speed of the bullet and weight to figure out a perfect weight of a bullet for the most kinetic energy. Good design tho.
Hobby Coilgun bullets are governed by completely different principles than rifles. Lets stop the comparison between the two until Hobby bullets reach mach 1.
to improve velocity: use a spherical projectile at 1/4 of the size of the present projectile. basically, an oversized BB. and then, watch as it goes flying out. then lengthen the projectile into a cylinder with a dome on top (basically, a bullet). make this one half of the length of the original projectile. rifle the barrel. add 2 more electromagnetic coils, and time these to start 30ms after the original coil starts (so, coil one starts at 0ms, coil 2 at 30ms, coil 3 at 60ms). then, see what happens. fine tune the coils until you have the perfect timing.
I believe the average velocity of a 9mm round from a common handgun is about 500-600 joules. The most powerful handheld coilgun i’ve seen is about 20-25 joules. The best efficiency I’ve seen thus far from a coilgun is about 6.6% with a LOW joule capacitor source (60 joules). The bottom line is coilguns are FAR too inefficient to be considered for a handheld weapon. The current design would need to be completely changed. My guess would be to utilize extremely high voltage (voltage translates to EMF) like upwards of 10,000 volts.
What if you used a slightly lighter and more streamlined pointed projectile? (Maybe hollow from the back end like a pellet or a mini ball.) Wouldn’t that improve velocity?
That would make the projectile faster, however it would contain much less energy because of the lighter weight (also you have much less material to magnetize). Therefore you need a different coil and maby even change the capacitors. You basically wind up disigning a whole diffrent coilgun.
@ jeremy: A coilgun is something different than a railgun, no matter how you look at this it is still a coilgun;)
Hey Daniel, I’m very interested in this coilgun you have here. I was wondering if you could list the parts used to create it (If that hasn’t already been done). I would also like to know what basic knowledge is required to make coilguns, experiment with them, and to be able to develop my own. Is there any way I could contact you?
All the electrical parts I used are on the schematic, you can find more information on my own site http://www.megavolts.nl/index.php/en/projects/geweren/46-megagun and you can also contact me there. If you plan on developing your own coilgun it might be an idea to build a microcontroller speedometer to monitor any progress (or just 5 sheets of thin cartboard:) ). cya there.

Daniel, I have a question that will seem quite trivial to your engineering here.
I really like the color of the LEDs used to illuminate the gun. Can you tell me what kind you used? I can’t tell if they’re blue, violet, blacklight or?
A part name or supplier would be ideal. Thanks!
They just seem blue to me;) I got them from a pile of junk at my school. There is no serial number or anything on the bag, so i’m afraid that I can’t help you with that. Maybe there is a way to translate the color on the picture back to a specific wavelength, you can then try to find leds with a simular color.

No, im not going to use it on humans…. but the squirrels in my yard……! Let me know if u can give me the plans or if i need to pay u or watever. Thanks, Brennen

Take a look at http://www.megavolts.nl/index.php/en/projects/geweren/46-megagun all information on the elektrical system is there, that’s basically all you need to know to build it.

[...] Have a look at this beautiful Mini Acrylic Tesla Coil Project that our friend Daniel Eindhoven from Megavolts.nl put together. The build detail on this project might even rival the MV CoilMaster Mark1 Coil Gun! [...]

Daniel, I have a question that will seem quite trivial to your engineering here.
I really like the color of the LEDs used to illuminate the gun. Can you tell me what kind you used? I can’t tell if they’re blue, violet, blacklight or?
A part name or supplier would be ideal. Thanks!
PS Great work.

They just seem blue to me;) I got them from a pile of junk at my school. There is no serial number or anything on the bag, so i’m afraid that I can’t help you with that. Maybe there is a way to translate the color on the picture back to a specific wavelength, you can then try to find leds with a simular color.
