As a firearm guy I'm a big fan of your setting to drain the power from the weapon to make it safe so it won't shock you. You didn't have to make all the extra programs and devices that helped you make the rifle but it's amazing that you did. It's a great idea for making a 2nd iteration or making others for someone else.
Niceee! Its frankly refreshing to see a coilgun project that takes efficiency into account, I really love that spreadsheet. Anyone can design a good looking rifle, but if it doesn't have the performance to match then the proof is in the pudding as they say
Thank you! Though I don't think this design is fully optimized just yet though, as all the coils are the same. When mapping the field of various coils with my CNC, I had to manually increment the Z height by 1mm, and then actually write down the inductance and field values in a chart. So I got lazy, and just used one coil rather than optimizing a new coil for each stage. I do, however, have an idea for an automated field mapper that would increment the stepper motor, read inductance, read the field strength, and then send the resulting values to my computer to be automatically entered into a spreadsheet. That would make the optimization process much easier.
As someone who works with E&M in industry, this is so incredibly well done. Going through the effort of measuring and documenting, not to mention publishing it all, is incredible. I have worked with professional companies that could learn so much from your practices. Great work!

Thank you! I'm working on a redesign that uses no moving parts. The barrel will have a stator built around it that creates a rotating magnetic field, and the projectile will act as the rotor of a reluctance motor.
I have a couple of ideas for it, altoug it may elevate it to a sniper rifle kind of size and power.

I believe this would be more energy eficient and allow more and faster rounds downrange with a given battery Third, and this comes from the munition change, automated testing of the time delays to archieve optimun speed. Or in other words, let the gun fire itself autonomously while testing delays until it finds an optimun delay for each coil. Bonus points if it draws a nice chart with every interation of time delay and final speed.

I’ve been wanting to start a project like this for a long time, but a Gauss gun has always seemed way too intimidating to safely approach, so I can’t thank you enough for providing your own information.
Masterfully done. Making your own tools to make your own tools, and you really created the whole package-- efficiency, looks, performance, portability. Impressive. And THANK YOU for the writeup.
i currently also building a coil gun. you did something i also want to do which is honestly such a obvious thing what all the others didnt do. spinning the projectile for stabilisation. well, i still have a long way to go. currently i'm designing the charging circuit. Well done sir.
So yeah. I think the tube creates a vacuum on the backside of the projectile. It might help to either add some deep rifling to add spin to the projectile and also allow some pressure equalization. That or you could drill holes through the barrel toward the back.
I don’t comment often, but I’m upset I’m 2 years behind this project and just seeing this video now. By far the best rifle I’ve seen on RUclips ever. Please bore me with more detailed explanations!
Amazing work! I'd love to see a short video about the capacity of your gun to fire needles. Less impact energy, but far more speed. Keep up the great engineering!
Coil guns are rather unintuitive because a smaller projectile will not necessarily go any faster. The reason for this is that a smaller projectile has less metal mass for the magnetic field to pull on.
You are awesome! Freaking inspired me to freehand construct a raygun that fires 5 watts of laser power last night. I reused some components I had laying around and I had a whole bunch of junk laying around everywhere here so it's partially made from an ancient Electrolux vacuum cleaner and several other things. Handheld, like a ballistic handgun and can be fired by pressing a button with your thumb. It will drill a hole in the sidewall of a vehicle's Tire if stationary. If it's possible to catch something on fire you can catch it on fire from quite a distance, if you simply aim and hold still. You can catch dark things on fire easiest because dark colors and black absorb light best. Unfortunately I used the wrong battery configuration and I made it so that I have to partially disassemble the thing to get the batteries out and recharge them because I forgot to put in the charge port I was going to repurpose. If you point it at your own self carelesslike, it starts to sizzle and tingle and hurts lol. I found some orange eye protection supposed to be rated for around the wavelength and power output because i dont want to be blind. I'd show you a picture but I don't think they let you on RUclips.

You lucky son of a c**t f*cker LOL Thanks for working so hard and sharing, so we can all appreciate the things you do and the person you are- Rich
Impressive job, well done. Here are just some advice that might help you since I worked a lot on coilguns for my uni project. Try using some washers at both ends of the coils made of epoxy and ferrite.and also try to minimize the airgap between the barrel and the projectile.and don't underestimate the effects of good aerodynamics on the bullet. you can also use a stepped coil geometry for the first coil, and since the projectile passes the the coils with different speeds, you may wanna use different inductance and capacitance values for each stage. Nevertheless, excellent job.
I was thinking the same thing about the stepped coil spacing (I am not an engineer, but it seems similar to how simple magnetic accelerators work). He mentioned possibly cooling the coils, which made me think of the water-cooled coils used in induction forges. Would using a modified version of something like these make for better coils for creating a stronger field as well as being able to cool the coils?
im blown away by the amount of effort and different fields you implemented single handedly. Instant subscribe! cant wait to see what else you come up with in the future!!
If you find that the Arduinos timing starts to become a factor the raspberry pi pico boards has what they call programmable IO which allow for really fast timing. The documentation is also second only to Arduino. Thanks for sharing this project that's very impressive professional grade engineering!!
Very impressive man, very impressive indeed! All the time and engineering that went into this must’ve been a massive commitment, respect. The gun itself is so freakin cool! Lol, enjoyed the hell outta this video, and having ‘Just Jammin’ playin in the back as well 🔥
I am very impressed by your efforts to characterize and simulate the electromechanics, especially the accuracy of the predictions. Did you simulate the back emf from the moving magnetized projectile? I assume the energy transfer would show up in the coil as a back emf and be dependent on the velocity. Did you simulate this much detail, or just assume a simple capacitor/inductor circuit? I would be really interested in an in-depth explanation of your characterization and simulation process.
Thank you! The simulation accounts for the projectile increasing the inductance of the coil, and also the energy stored in the coil aswell as the resulting back-emf across it when the IGBT turns off. The one thing it doesn't account for is the hysteresis of the projectile inducing a current in the coil.
I completely missed the last part of your comment. I would enjoy making a video about the specifics of creating an excel simulation, though I don't think many people would watch it. I'd be happy to make one if people showed enough interest. Alternatively, I'd be happy to get into discord with you and tell you all about it.
@@BenjaminMarshallScienceMan No problem! That's understandable; I agree that a video might not be the best format, but perhaps a new section in your design guide showing the theory/math behind the spreadsheet formulas would be nice. I may eventually be interested in reproducing the simulation in python, as that could open up possibilities for numerical optimization which could squeeze even more performance out of the system.
One possible avenue for extra performance is mentioned in my design guide, though I was having trouble simulating/building it. You should be able to redirect the back-EMF of the coil at the end of the shot into the next stage with a diode. This would result in the next stage experiencing a voltage spike right at the beginning of firing. Such a voltage spike would serve to get current flowing through the coil more quickly, thus building a field more quickly. It also has the advantage of drastically reducing the fall-time for the previous coil since you dont have a flyback diode causing the current to loop through the coil.
I actually incorporated temperature into my simulation after making this video. Reducing the temperature of the coils down to 0 degrees celcius only had a miniscule impact on final velocity. I think I'd have to get them much cooler to see any serious improvement. As for superconductors, unfortunately copper doesn't superconduct at low temperatures like other metals. And building a coil out of superconducting material is a bit outside my skillset at the moment.
9:22 after this sentence u have my utmost respect sir ! Put such information for free is really valuable and not something that people do ( which I completely understand ) Anyways this was a great video !
I suggest placing a power resistor in series with the flyback diode. After the projectile leaves the coil you want the inductor current to reduce as fast as possible. A resistor helps with that. Optimise for the maximum voltage your IGBT can handle.
It is like a dream, you think up something you are interested in and you visualize what you want to do then engineer and even produce it right at home. I bet a guy like you would benefit from having more tools of fabrication and production since you know how to visualize, engineer, design, and produce a product on your own. Next thing we know we will find out you will have laser cutter, cnc mill, lathe, welder, etc... making anything you imagine. You would make a good machine builder since you do the engineering, testing, research, the tech work, and the fabricator work.
this is so underrated!! the fact that it's ACTUALLY a rifle too. i wonder if making the metal rods sharper like a bullet would help making it more lethal.
Now just add a rotating drum magazine to load the shots for you and you have Destiny 2's Centrifuse Auto Rifle; One of my favorite guns in the game and it's truly incredible to see something resembling that gun both in functionality and form in real life, and so masterfully crafted! Kudos to you!
Good job on the project, so much attention to detail on the mechanical construction. Upgrade: if you want to have higher power coupled with higher efficiency you must use Litz wire for your coils. choose the right gauge and number of strands of Litz wire for your current density and current rise/fall time(times will be faster with Litz). this will be a bit expensive but if you're looking for bleeding-edge performance then spare no expense, this way you won't need any cooling system for the coils either; considering you have chosen the right Gauge / Number of strands. Also, I would use a passive projectile twister instead of an active one to boost efficiency, like a rifled barrel.
"also it can spin the projectile before firing"..... *LOVE* What an interesting solution vs trying to spin with sectored coils! Would love to see tests with and without the spin enabled? Awesome work!
You could massively increase velocity by decreaseing the size or weight of the projectile , also sharpen a point onto the projectile nose , if you where getting around 130 fps if you cut the projectile weight in half and made them sharp it would probably be letheal Look into projectile gr vs velocity in firearms it should explain alot for you , ive got no idea how much performance you could gain but i do know for a fact that the size of your projectiles is retarding its performance 1000% lighter = faster , faster = letheal , letheal = practical Super cool project bro , as a gunsmith i loved every second of this ❤️ mad props bro youve done somthing incredible!
Thank you! I'm glad you like the video. Initially I shared your intuition about reducing the size of the projectile, but the interesting thing I ended up discovering about coil guns is that reducing the mass/size of the projectile ends up having a negligible effect on the muzzle velocity. The reason it benefits firearms is because you have the same amount of force from the gunpowder being used to accelerate a smaller mass. In coil guns, the force comes from the magnetic field interracting with the ferrous projectile. So reducing the ferrous mass also reduces the force exerted onto that mass. Unless there are possible design changes that I am simply not thinking about, it seems like coilguns are best suited to hurling heavy projectiles at a comparatively low velocity, kind of like a bow and arrow.
I remember my dad building a coil gun when I was a kid in the 80s. Before cheap Atmega boards and 3d printers were a thing. He was always trying to invent toys, his idea was for a Nerf "bazooka" that would fire foam "rockets" with an iron ball in the middle. Used optical switches for the coils. It never would have worked well with 80s battery technology.
The Gauss Rifle needs to be the next generation of firearms technology. We have been relying on chemical based firepower for over 800 years now. And while it still has a solid place in hunting, self defense, and military applications, it's clear that magnetic rifles need to be developed, starting from individuals like the one in the video demonstration. And this is where innovation begins. At homes, garages, studios, and even the living room or a spare bedroom!! Slowly as we gain that one grain of knowledge, with time, our descendents will look at this and go "This is where it started". And as Gauss Rifles advance, smaller capacitors, larger energy density and storage, and multiple projectile use, they will become a welcome addition to the armies of the future.
Coil guns will be the future. With advancements into capacitor technology, advancements in lithium ion (or some other form of battery we havent found yet) and idk some way in hell to condense coil space while upping velocity, im thinking there is a future in warfare with coil tech. I want a rail gun at home that i can plug a dewalt or milwaukee battery into that will give ballistic performance of a 45acp.
Late to the party, but I _must_ commend you on your build AND your generosity in sharing it with us plebs. If only I had your chops I'd be making all sorts of cool gadgetry myself...
Wow wow wow! This is a massive engineering undertaking and you made a true work of art. Furthermore you shared your knowledge. I do not know you but I am VERY impressed and quite frankly proud. You demonstrate human ingenuity at the highest echelon and you did it just for the love of the game. Amazing!
When you can make one to break Mach 2 and propel a 250 grain rifled projectile, please let us know. Your design is so far clean and cool, but only at the level of a fancy slingshot. Thanks for posting.
its a smothbore electromagnetic gun. if you want to increase speed, penetration and acuracy you can change the ammo desighn. modern tank´s whit smothbore canons use fin estabilized sabot rounds ( APFSDS ) less air fricction, less mass = more speed ( kinetic energy = 1/2*mass*speed^2 )

FEMM is a free modeling software. Many DIY Wind Generator builders use it to identify strengths and weaknesses in coil designs. In FEMM you can see the magnetic field shape generated by the coil. Have you considered Graphene capacitors? Robert Murray-Smith has a lot of videos on making graphene and various uses as capacitors.
Now to make it magazine fed, more powerful (ie not fireable in your house..) and cover up the internals to protect them and more importantly making it look even cooler, oh and add sights other than the laser pointer, either slim irons or a red dot.
take this as both a compliment and as genuine advice: you should probably do some research into basic range safety practices before operating that thing any more, and probably add features like a safety switch that functions independently of the software, a sturdy trigger guard, and a drop safe trigger mechanism before further optimizing the power output. extremely cool project, love to see someone put some serious thought into optimizing the coils, best of luck with future iterations, also please don't do a mini therac-25 disaster to yourself!
That's amazing. But, the next trick is to upgrade it so it can handle more power. Gauss guns can theoretically outperform gas-propelled guns if the power source and its capacitors can handle enough energy to accelerate a bullet that fast. The military might take interest if a proof of concept is cheap enough, reliable enough, and consistently outperforms conventional 7.62-chambered rifles. To increase bullet mass, you could use lead jacketing a ferromagnetic core. Tungsten is better, especially for armour penetration, but more expensive. I'm happy to see working models, though. This is just the first step before mil-spec models evolve as the technology matures! :D
really cool not sure why you left the ends of the rods blunt though, that extra resistance seems like the sort of thing you'd want to engineer away, no?
Apart of The Arc Troopers uniform is a backpack, that would be perfect for a large power supply! Please at least three barrels! Please no coil gun, really interested in The Railgun and how having more barrels will diminish barrel damage! Last but not least this is easily one of the coolest and less known Star Wars weapon bc it fires projectiles!
Good job man! This is a great project. Kudos on putting in the work. The results are very impressive, especially how close you got between measured and simulated results.
Very cool project. I'm curious why you decided to use such a large slug though. A smaller slug could achieve higher velocity for less energy, and you could use smaller capacitors allowing for faster charges. I'm sure there's a sweet spot where you could have a sort of reverse Gatling - Small capacitor arrays constantly charging and alternating array activations with each trigger pull. So one barrel, but "rotating" capacitor arrays.
Gauss rifle that actually spins the projectile? This is immediately leaps and bounds ahead of practically any other I've seen on this platform.
I think it bounced off the wall.
It does make me wonder about the actual effectiveness to it, seems rather simple compared to helical coils
As a firearm guy I'm a big fan of your setting to drain the power from the weapon to make it safe so it won't shock you.
You didn't have to make all the extra programs and devices that helped you make the rifle but it's amazing that you did.

you also have to drain the power because it would become very dangerous, the capacitors could explode after some time.

im blown away by the amount of effort and different fields you implemented single handedly. Instant subscribe! cant wait to see what else you come up with in the future!!
WOW! This is absolute nuts! Really shows the effort you put in this project, and you deserve waay more.
I really like your solution to apply a spin to the projectile. that was a very clever touch!
You never cease to impress, thank you Papa Marsh ;)
If you find that the Arduinos timing starts to become a factor the raspberry pi pico boards has what they call programmable IO which allow for really fast timing. The documentation is also second only to Arduino. Thanks for sharing this project that's very impressive professional grade engineering!!
Very impressive man, very impressive indeed! All the time and engineering that went into this must’ve been a massive commitment, respect. The gun itself is so freakin cool! Lol, enjoyed the hell outta this video, and having ‘Just Jammin’ playin in the back as well 🔥
Hearing that intro guitar riff still gives me goosebumps, over 2 decades later. Amazing engineering project, absolutely mind blowing!
I am very impressed by your efforts to characterize and simulate the electromechanics, especially the accuracy of the predictions. Did you simulate the back emf from the moving magnetized projectile? I assume the energy transfer would show up in the coil as a back emf and be dependent on the velocity. Did you simulate this much detail, or just assume a simple capacitor/inductor circuit? I would be really interested in an in-depth explanation of your characterization and simulation process.
Thank you! The simulation accounts for the projectile increasing the inductance of the coil, and also the energy stored in the coil aswell as the resulting back-emf across it when the IGBT turns off. The one thing it doesn't account for is the hysteresis of the projectile inducing a current in the coil.
I completely missed the last part of your comment.
I would enjoy making a video about the specifics of creating an excel simulation, though I don't think many people would watch it. I'd be happy to make one if people showed enough interest. Alternatively, I'd be happy to get into discord with you and tell you all about it.
@@BenjaminMarshallScienceMan No problem! That's understandable; I agree that a video might not be the best format, but perhaps a new section in your design guide showing the theory/math behind the spreadsheet formulas would be nice. I may eventually be interested in reproducing the simulation in python, as that could open up possibilities for numerical optimization which could squeeze even more performance out of the system.
One possible avenue for extra performance is mentioned in my design guide, though I was having trouble simulating/building it.
You should be able to redirect the back-EMF of the coil at the end of the shot into the next stage with a diode. This would result in the next stage experiencing a voltage spike right at the beginning of firing. Such a voltage spike would serve to get current flowing through the coil more quickly, thus building a field more quickly. It also has the advantage of drastically reducing the fall-time for the previous coil since you dont have a flyback diode causing the current to loop through the coil.
That's a pretty sophisticated looking rifle! But only problem is you have to load it every so often!
I think this design could be improved dramatically with cryogenic cooling or use of superconductors.
I actually incorporated temperature into my simulation after making this video. Reducing the temperature of the coils down to 0 degrees celcius only had a miniscule impact on final velocity. I think I'd have to get them much cooler to see any serious improvement.
As for superconductors, unfortunately copper doesn't superconduct at low temperatures like other metals. And building a coil out of superconducting material is a bit outside my skillset at the moment.
One thing perhaps add tented glass to the sides to prevent damage to the coils when in combat. VERY GOOD WORK you are a very smart human!
Truly Superb effort! Impressive in every aspect, well done.
I can't believe this has existed for 2 years and ive just scene it wtf its a masterpiece
Thanks for a great analysis! Well done!
Ur a freaking genius dude
The halo intro is all I needed to convince me that this video was going to be fucking epic!
1.5 kJ is in the ballpark of 223 rem, an actual rifle cartridge. Different mass/speed, but damn impressive.
This has only 24 J muzzle energy, not 1.5 kJ. See 2:27.
With 1.5 kJ there would be a hole in the door behind his shooting range.
9:22 after this sentence u have my utmost respect sir ! Put such information for free is really valuable and not something that people do ( which I completely understand )
Anyways this was a great video !
Mass Effect gun !😄
I suggest placing a power resistor in series with the flyback diode. After the projectile leaves the coil you want the inductor current to reduce as fast as possible. A resistor helps with that. Optimise for the maximum voltage your IGBT can handle.
good job son
Thanks dad.
It is like a dream, you think up something you are interested in and you visualize what you want to do then engineer and even produce it right at home. I bet a guy like you would benefit from having more tools of fabrication and production since you know how to visualize, engineer, design, and produce a product on your own. Next thing we know we will find out you will have laser cutter, cnc mill, lathe, welder, etc... making anything you imagine.
You would make a good machine builder since you do the engineering, testing, research, the tech work, and the fabricator work.
I got all that and custom AI from leaked source code
can I buy one?
Bingo!
Proof of concept👍 Really needs about 100 MJ when the component tech advances sufficiently. The external design is really cool…looks proper syfi
pls make uzi's railgun
Fr that’d be epic
this is so underrated!! the fact that it's ACTUALLY a rifle too. i wonder if making the metal rods sharper like a bullet would help making it more lethal.
Damn he even got it looking drippy as hell unlike all other coulguns that. Are just balls of wire
Now just add a rotating drum magazine to load the shots for you and you have Destiny 2's Centrifuse Auto Rifle; One of my favorite guns in the game and it's truly incredible to see something resembling that gun both in functionality and form in real life, and so masterfully crafted! Kudos to you!
Looks more like a Wavesplitter ( Void Trace Rifle) lol
Good job on the project, so much attention to detail on the mechanical construction.
Upgrade: if you want to have higher power coupled with higher efficiency you must use Litz wire for your coils.
choose the right gauge and number of strands of Litz wire for your current density and current rise/fall time(times will be faster with Litz).
this will be a bit expensive but if you're looking for bleeding-edge performance then spare no expense, this way you won't need any cooling system for the coils either; considering you have chosen the right Gauge / Number of strands.
Also, I would use a passive projectile twister instead of an active one to boost efficiency, like a rifled barrel.
"also it can spin the projectile before firing"..... *LOVE* What an interesting solution vs trying to spin with sectored coils! Would love to see tests with and without the spin enabled? Awesome work!
Always wanted to make something like this. Very clever idea spinning the rod prior to firing!
This is easily genius level intellect to be able to pull this off, huge respect to you man. You're easily the smartest person I've seen.
I was on the fence during the intro but the explanation of all the steps and the winding counter made this sub an easy decision
You could massively increase velocity by decreaseing the size or weight of the projectile , also sharpen a point onto the projectile nose , if you where getting around 130 fps if you cut the projectile weight in half and made them sharp it would probably be letheal
Look into projectile gr vs velocity in firearms it should explain alot for you , ive got no idea how much performance you could gain but i do know for a fact that the size of your projectiles is retarding its performance 1000% lighter = faster , faster = letheal , letheal = practical
Super cool project bro , as a gunsmith i loved every second of this ❤️ mad props bro youve done somthing incredible!
Thank you! I'm glad you like the video. Initially I shared your intuition about reducing the size of the projectile, but the interesting thing I ended up discovering about coil guns is that reducing the mass/size of the projectile ends up having a negligible effect on the muzzle velocity. The reason it benefits firearms is because you have the same amount of force from the gunpowder being used to accelerate a smaller mass. In coil guns, the force comes from the magnetic field interracting with the ferrous projectile. So reducing the ferrous mass also reduces the force exerted onto that mass. Unless there are possible design changes that I am simply not thinking about, it seems like coilguns are best suited to hurling heavy projectiles at a comparatively low velocity, kind of like a bow and arrow.
Nice work on keeping your code tight and efficient enough to run all of that in under 600 lines. Impresive.
ok this guy put in all the work and pretty much free sourced it to us which is something not very many other creators do he needs more
Good on you for the amount of effort and documentation passed on in this project... you should be proud of yourself.
I remember my dad building a coil gun when I was a kid in the 80s. Before cheap Atmega boards and 3d printers were a thing. He was always trying to invent toys, his idea was for a Nerf "bazooka" that would fire foam "rockets" with an iron ball in the middle. Used optical switches for the coils. It never would have worked well with 80s battery technology.
I call dibs on this guy for my apocalypse camp
Just read your design doc. Incredible work. I had some of the same ideas myself but nowhere close to what you did. Awesome.
‘That’s why my project is this sick as hell railgun!' -Uzi Doorman
The Gauss Rifle needs to be the next generation of firearms technology. We have been relying on chemical based firepower for over 800 years now. And while it still has a solid place in hunting, self defense, and military applications, it's clear that magnetic rifles need to be developed, starting from individuals like the one in the video demonstration.
And this is where innovation begins. At homes, garages, studios, and even the living room or a spare bedroom!! Slowly as we gain that one grain of knowledge, with time, our descendents will look at this and go "This is where it started". And as Gauss Rifles advance, smaller capacitors, larger energy density and storage, and multiple projectile use, they will become a welcome addition to the armies of the future.
That was amazing! I’m blown away by what a single person is capable of designing and building such a device!❤
I have worked with a team of engineers and programmers to attain similar things to what you did on your own. Very impressive.
That is the single coolest thing I have ever seen on youtube, and its CRIMINALLY UNDERRATDE!
Coil guns will be the future. With advancements into capacitor technology, advancements in lithium ion (or some other form of battery we havent found yet) and idk some way in hell to condense coil space while upping velocity, im thinking there is a future in warfare with coil tech. I want a rail gun at home that i can plug a dewalt or milwaukee battery into that will give ballistic performance of a 45acp.
This video deserves waaaaaaaay more views! Impressive stuff man!
Late to the party, but I _must_ commend you on your build AND your generosity in sharing it with us plebs. If only I had your chops I'd be making all sorts of cool gadgetry myself...
Wow wow wow! This is a massive engineering undertaking and you made a true work of art. Furthermore you shared your knowledge. I do not know you but I am VERY impressed and quite frankly proud. You demonstrate human ingenuity at the highest echelon and you did it just for the love of the game. Amazing!
When you can make one to break Mach 2 and propel a 250 grain rifled projectile, please let us know. Your design is so far clean and cool, but only at the level of a fancy slingshot. Thanks for posting.
its a smothbore electromagnetic gun. if you want to increase speed, penetration and acuracy you can change the ammo desighn.
modern tank´s whit smothbore canons use fin estabilized sabot rounds ( APFSDS )
less air fricction, less mass = more speed ( kinetic energy = 1/2*mass*speed^2 )
The "D"charge button was an excellent I.D.
Awesome! I want one. Looking forward to see what future developments you make on this.

FEMM is a free modeling software. Many DIY Wind Generator builders use it to identify strengths and weaknesses in coil designs.
In FEMM you can see the magnetic field shape generated by the coil.
Have you considered Graphene capacitors?
Robert Murray-Smith has a lot of videos on making graphene and various uses as capacitors.
Its amazing how you made it all happen and also how bright and clever you are
this needs a billion views. we need to fund this man with some grants. good science here.
Now to make it magazine fed, more powerful (ie not fireable in your house..) and cover up the internals to protect them and more importantly making it look even cooler, oh and add sights other than the laser pointer, either slim irons or a red dot.
take this as both a compliment and as genuine advice: you should probably do some research into basic range safety practices before operating that thing any more, and probably add features like a safety switch that functions independently of the software, a sturdy trigger guard, and a drop safe trigger mechanism before further optimizing the power output. extremely cool project, love to see someone put some serious thought into optimizing the coils, best of luck with future iterations, also please don't do a mini therac-25 disaster to yourself!
I was told that you can't wear a Magnum P.I. shirt without a catapilar mustache.
That's amazing. But, the next trick is to upgrade it so it can handle more power. Gauss guns can theoretically outperform gas-propelled guns if the power source and its capacitors can handle enough energy to accelerate a bullet that fast. The military might take interest if a proof of concept is cheap enough, reliable enough, and consistently outperforms conventional 7.62-chambered rifles. To increase bullet mass, you could use lead jacketing a ferromagnetic core. Tungsten is better, especially for armour penetration, but more expensive. I'm happy to see working models, though. This is just the first step before mil-spec models evolve as the technology matures! :D
really cool
not sure why you left the ends of the rods blunt though, that extra resistance seems like the sort of thing you'd want to engineer away, no?
DARPA furiously taking notes in the background.
Please create a Rotary Railgun based on Star Wars Arc Troopers shoulder mounted Chaingun!🙏👍
Apart of The Arc Troopers uniform is a backpack, that would be perfect for a large power supply! Please at least three barrels! Please no coil gun, really interested in The Railgun and how having more barrels will diminish barrel damage! Last but not least this is easily one of the coolest and less known Star Wars weapon bc it fires projectiles!
Benjamin Marshall proves that there is still the potential for Renascence Men in this age.
Good job man! This is a great project. Kudos on putting in the work. The results are very impressive, especially how close you got between measured and simulated results.
Very cool project. I'm curious why you decided to use such a large slug though.
A smaller slug could achieve higher velocity for less energy, and you could use smaller capacitors allowing for faster charges. I'm sure there's a sweet spot where you could have a sort of reverse Gatling - Small capacitor arrays constantly charging and alternating array activations with each trigger pull. So one barrel, but "rotating" capacitor arrays.
