Suggestion- 1) make a bullet(s) made for the gun that fits it perfectly. Not long as it may spin out of control like it did And/or 2) make a bullet stabiliser so that the bullet actually goes straight rather than tumble Also this is just a suggestion. I don’t know anything about how to do this. Also What you guys have done is astounding. Keep it up!

[@andy-in-indy]

@@violet9214 I can't think of any form of stabilization that would not slow the projectile. The Second Rule of Rocket Science states "If you want it to go straight, the ass end has to want to go slower than the nose."

For future upgrades: More power. If those wires aren't smoking they can have more power run through them. Also, thinner wire, more turns on the later coils. The projectile is moving increasingly faster, so each stage down the barrel is turned on for a shorter period of time. That means they can use thinner wire with more turns (more powerful magnet) because power will be applied for a shorter amount of time so they won't overheat. The last stage coils should be thin as hair. (Also, $1500 on wire? Jeeeeesus). Really cool to see Charles front on center for so much of his own build (though the Tony Stark cutaway was perfect).

[@prestong2292]

MattsAwesomeStuff thin wire also affects how much electricity runs through them

[@Ariccio123]

@@prestong2292 yeah, you have to tune it so the resistance of the wire and the inductance of the overall assembled coil so that it saturates at *just the right time*. You also don't want too much inductance, otherwise the coil won't be able to turn all the way off before the projectile passes it.

[@Deadorbiter_]

They cannot, unfortunately, Canadian laws would basically make it look like they built a functioning nuclear bomb... or something. (Excuse my ignorance, I’m not 100% sure)

[@charlesholtforster9651]

Hi Matt, Charles here. I'm glad you enjoyed the project! I had a great time building the thing! The reason for using thicker wire is not that we are worried about it melting, but that the resistance of thinner wire is very high compared to the rather monstrous 14AWG we used. The limiting factor is the boardmount MOSFETs I chose to use - they could only suffer so much current for so long. Having more turns of thin wire would actually reduce the magnetic field strength and the current, while increasing the inductive time constant, meaning that we would have to turn the coil on earlier to get full performance, and it would be less performance. The later stages should be thicker wire, while the earlier stages could be thinner wire, since the time constant matters less when the projectile is slower. Also, not quite $1500 on wire. There was a mix up. Overheating had nothing to do with it. As it is, we fired it 400 times in an afternoon and it only got mildly warm. For more power, we need better transistors, or at least more of them in parallel. The failures we had were due to leaving the coils active for too long, causing a failure in the MOSFET on that stage, or the current sense resistor on that stage. It was quite something to solo the design and build, though I had major help from the rest of the team with the construction!

[@lonnie776]

Additional future upgrades: So first off I am certainly not an electrical engineer however I do tend to get a good/novel idea every now and then. I believe if you were to attach a neodymium magnet to the back end of the projectile and instead of producing a simple on off, you were to produce a full square wave (Sine wave would be best). You could no only pull the projectile, but once it cleared the center of the coil you could then reverse the polarity with an H-bridge and push against the magnet to produce even more acceleration and velocity. It would certainly be a complex build and I'm not sure you can reverse the voltage that fast due to flyback voltage but if you could get it to work, I think it would greatly increase the projectile velocity. Just a thought.

1) Have you tried steel ball bearings? 2) Could the projectiles be machined so that they spin like a rifled barrel would do for a conventional bullet?

[@eslachance]

I was going to comment the same thing as #2, since that projectile going sideways is really weird. Making it a bit more aerodynamic as well as rifling it for a spin sounds like a good idea. Additionally, I kept thinking this thing is still underpowered because it really looks like they're timing all the coils with the exact same delay (at least I haven't heard otherwise) and that doesn't make sense to me - the projectile is accelerating so the timing needs to be shorter as it goes forward.

[@AhmedRw]

@@eslachance They did , there's a sensor btween every coil that detects the bullet and turns off the previous coil and turn on the next at the same time , and if you watch the video carefully ull see he calibrates the sensors to determine the best time to do the coil switch, and he does that for each sensor separately , which fixes the acceleration automatically coz the individual timing .it's not them been precise, they have to do that coz if timing was even slightly off the bullet won't come out or it'll shoot back word or it'll come out with a little power.

[@bonkyouded]

what you could do to make automatic rifleing is make a projectile that has fins that go into the rifleing. This way when it's pulled forward it will start to rotate.

[@kumat0ra672]

@@bonkyouded Or just make it a fin-stabilized discarding sabot projectile to begin with.

[@multi-mason]

Or use a motor to spin up the projectile before firing. Could make the trigger start spinner motor on pull, and fire on release, which would be a familiar mechanic to most gamers. Plus it you couldn’t wait the 1 second for spin up, you could always release early, at the cost of more drop, less range, worse accuracy, and weak penetration… Clearly it would be better to let it spin up, but you could release after 200 milliseconds and have spin, just not at max rotation speed. 500 milliseconds (half a second) and you get pretty good spin, so projectile will hit straight and get penetration, and it will go further with accuracy, but the spin would wind down and it would tumble at very long range, and at that point forward velocity would also be diminished somewhat, so it would drop fast. At extreme range, you’d really want to let it spins up fully and make each shot count. I think their projectile is also too heavy for the coils they are using. A slightly longer but much thinner projectile might work better. I’m not sure of projectile requirements for the coil method, but if it could be partially hollow with a solid tip, I think that would be ideal. Bolt action seems a little silly too. I mean I doubt that the stability of the bolt mechanism will improve the shot in anyway, as it does with high end bolt action rifles, that are precisely machined. I mean most of the benefit a high quality bolt action imparts is because of the way powder burns, where a precisely engineered bolt leaves less room for pressure to escape in little ways here and there which effect power, accuracy, and predictability. Basically, a more tightly controlled explosion. All of that is completely irrelevant with the coils. I think the idea of “50 caliber” coil gun negatively impacted their results. Energy and time spent facilitating the pointless bolt action, would have been better spent elsewhere, while the large (was .50? I’m not actually sure) projectile would have probably been more effective if it had been lighter, more streamlined, and not tumbling.

One of the reasons that your gun was so inefficient is: you need to use pipe pieces as projectiles. The bigger the radius, the higher the induced ring currents. Pipes should also offer better flight characteristics. Finally, they should be out of copper, gives you 3x the energy, since it has 3x less specific resistance than steel.

This coil gun is mainly relying on the ferromagnetic properties (reluctance) of iron, not eddy currents (induction).Actually eddy currents are bad, since they transform the energy in to heat. Best choice is either solid iron or iron powder, joined by some non-conductive material. Both have their pro and cons

Great job. Good to set it up like this so you don't get demonitized. Now few small suggestions which I think you already had in mind. Reduce coil chamber size, reduce bullet length so it weights less (easier to bring up to speed), amp up the wave function (for more speed), have barrel just miss touching bullet and drill holes down barrel in spiral to reduce pressure waves in front and behind the bullet (to allow less resistance, greater speed, and possible rifling).

Incredible you actually made it. One thing that might maximize the "lethality" would have been the creation of a bullet with optimum aerodynamic shape and less weight. That's because I noticed that it's time it hit the target did it, not with the tip but the whole body of the bullet. That means that the air drag reduces the speed of the projectile and created torque that put the bullet in an unstable pathway.

I think replacing an insulated fire tube with a spiral design on the inside will increase the projectile's accuracy throughout its flight. It'll create a horizontal axis on the projectile while it's in mid-air allowing it to spin and thus increase accuracy. Lol wishing for another future hacksmith electromagnet gun.

[@cristianespinal9917]

What weight projectiles were you using and what kind of velocity did you get from the projectile as it left the muzzle? For accuracy, you can try using a projectile shaped like a badminton shuttlecock instead of a cylinder. I'm guessing that using lighter projectiles will throw the timing completely off though since you'd reach higher speeds.

[@charliethetinkerer]

[@arhumzia6541]

[@DrPipedream]

It is all about the hybrid. Coil + rail. Imagine if the projectile was an electromagnetic dart energized by the barrel. Magnet field on magnet field is stronger than magnet on iron alone. This way you can also flip flop the coil polarity to both pull the dart through and push it out doubling the force. A sabot dart negates the need for any rifle spin for accuracy as well. sigh... someday.

[@crwydryny]

One point on how the coil guns work, theoretically it's possible to get more velocity by magnetically doping the rounds and switching the polarity of the coils so that it puls tge round towards it then as it passes the centre line starts to push it forward as the next coil pulls. Granted this requires precise timing in switching the polarity otherwise you lose efficiently Also using smaller lighter rounds would mean higher velocity and thus higher kinetic energy (E=½MV²)

[@StefanThiesen]

Love u guys. Your videos remind me of my years in tech R&D, that weird mix of play and serious work. There is no real creativity when there is no fun in what we do. Physically the coil gun is quite interesting. Also a bit unsettling. Your version is inferior to even a 20 lb recurve bow, but... thinking further... automatic magnetic feeding with, well, anything ferromagnetic that fits the size. Real time projectile analysis and magnetic adjustment to every projectile. Real time sensor based adjustment of coil flux... and if we think superconducting coils, we are in really messy realms... On the bright side we could say that warfare would be more environmentally friendly. Oh my.

I also wonder, since it looks like you're overloading the components in the board...perhaps it might be viable to run two coils in the same section?
