In this video I will show you how to turn on and off coils precisely in order to create a coilgun. In my case it is a pretty harmless "gun" that can accelerate ferromagnetic projectiles to safe speed levels.

I remember my first coil gun about 15 years ago. I used disposable cameras for the capacitor bank [about 8 i think] and the charge circuit, a pen for the barrel, drill parts for the handle and trigger... I wish I hadn't lost it.
I thought this was going to be about a gun that creates coils, but this is even better :D
i did too
😅😅😄 same here
Same thing
redstone craft guy do you even vape? Bro?
:v :v :v :v :v :v :v amazing!
NO!! THE STUDIO LIGHT HAD SO MUCH TO LIVE FOR!!
This could be really cool if you were to turn it into an hour clock, make the gun shoot vertical, and add a plexiglass tube to the end with a bell at the top, at the end of the hour the bolt would shoot up through the tube and ring the bell and fall back down to be shot at the next hour!
When I was experimenting with my own coilgun I used transformer inductor with circuit from the old camera flashlight which was increasing voltage up to 300V and firing 7mm steel BB from the single coil. Now It's stored in my eletronic box so I'll build it up again very soon and possibly make a video about it

5 years have passed, where is your coil gun video!
@@kerbatonbaton8108 Totally forgot about it xd. Strangely enough I still have that gun and I'll try to make it happen not very soon cause I now have other interests mostly related to car stuff.
@@Northaxe Do you still have that coil gun?
@@andriohalfer4615 yup i do!
Nice! But i want to see a new coilgun capable of "destroying" objects. So, do it with some powerfull capacitators. Pls, as soon as possible
hehexd
Flickerino
I need it!!! (Nope!)
If you want it to be powerful, upscale it so it can push out a higher weight projectile at faster velocities
Oliver Church
I know it. More coils, a lighter projectile and some big caps. But i don't know the ciruit for controlling the coil, charging and discharging the caps, etc, etc. So i need to wait a new video from GreatScott
me too
I just realized that I’ve been watching videos from this channel for at least a week and just now subscribed. Don’t forget to subscribe!
You can not please all the people all the time, just keep up the great content.
Cool! I think I'll try this concept to create a impact tester for composite panels. I'm curious how consistent the velocity is.
yes, the videos are getting better and better
Could you please do a series where you make diys which are quite easy to build plus cheap....
good explanation
wow profe te encontre, deberias hacer esto en tu canal
You actually are a genius...
Super cool build this week
+GreatScott! I have become a huge fan of your channel. Your videos are just awesome. Keep up the good work. Most projects would become expensive for me to build but I enjoy those even by watching your videos. Thanks again.
You really are Genius Mate! Can you make a DC to AC converter to use appliances running on car battery can be used at home?
Thank you Scott!!
"And i will see you next time" thats why im here :D
As ass bende burdayım kanalımabakın

Well, "stay creative" with your comments here ;)
Selam kardeşim.

i saw some hate in the comments, i just want to say that your content is great and in my opinion keeps getting better, i actually would enjoy more complicated projects and look forward to every next video of yours , you are doing great work
I just want to say I have 0.5% understanding of what is going on but I love how deep your explanations are. 1% of the time I'm like " hey I know them words ". love the videos keep them up
Greatscott is gonna kill us all :D
I also want to say that your video's are getting better and better every episode!

Great job Scott!
Dude! Thanks so much for the simple explanation!
Man, he speaks singing😂
I love the yes brand battery.
some time ago I wanted to make a coilgun with a bunch of big coils and big capacitors where the metal projectile would touch some contacts to activate the coil, that would create some frition losses but make the thing simpler (and possibly melt the contacts)
Awesome project bro, tnx for sharing it!!!
Reduce the diameter, reduce mass of sharpnel, increase the number of windings , keep constant input voltage, or use big caps for more efficient gun
what diameter do you recommend?
mark broeken I recommend no diameter
now we just need 20 tons of coil and a million volts and we have a railgun
Not to be douche but that's still a coilgun. Railguns operate in a different way, much more elegant IMO. Wikipedia will tell you all about it :)
Railgun does not use coils -_-
I wonder if it could be improved by maybe using an opamp on the secondary coil to detect the induced rising edge as the projectile enters it. That could then be used as the trigger to avoid having to cut in to the barrel or use IR sensors.
i love these vids.thanks great scott
can you change the arduino with an ATtiny85 with the same codes ?
No. You have to change the code.
@@greatscottlab shit
Im 2 years late but you can find online converters. For example: arduino to micropython
Winding coils in parallel is much better than in series, if we want to reach very high current with low voltage.
Finally someone that clearly explained how to make a coil gun! Will you be making another video in the future explaining how to use capacitors?
Looks like lots of fun! Might make one myself...
Great but... Why, why Arduino? Would it not be mush more intresting if you had used classical ICs? Every video on electronics is with microcontrollers now, i miss the old analogic stuff :/
You mean like logic gates? Or what kind of ICs do you have in mind?
Sorry, i meant the old school electronics without microcontrollers.. I don't know, things like opamp, ne555 and so, I don't know exactly how to do a similar thing with them, that's why i'm so intrested with them, 'cause all I see today on youtube is Arduino and codelines.
Sorry for my English
I think that might be an interesting video. I could create a similar circuit without coding. With logic gates, RC circuits and OpAmps. Wait for this weeks video.
Thank you very much :D
You got that right. I always try to find a way to avoid microcontrollers, and I almost always get by without using them. Cheers :)
codys lab made a fairly large one today. :D
I'm also trying to build one but i thought of using the analog pins of my arduino for my optical sensor. That way it's easier to set a value on which the switch gets triggered. But are analog pins fast enough in comparison to digital pins?
BEST PROJECT YET!!!
To get more patreon subscribers I'd say to create exclusive videos for them or release them early...
Id personally like to see longer projects like you making a cnc mill or something.
Patreon supporters can see the videos earlier.
+GreatScott! Ah beat me to it.
every time watch your videos I realize how much stupid I am!!!
This may have been said before, but those blue screw terminals can be connected to each other before soldering. Each has a tongue and groove so you can make them whatever length you want before soldering them in. The slots are just so small they're hard to notice.
What sort of delta printer do you own
Oh ja und gruss aus der Schweiz

Great video, that acent is soo great
That's cool, but could be more dangerous =3
more coils
How come dancing asses and silly prank videos get more views than this?
Keep up the good work friend.
I enjoyed this video and think it's a nice little project.
don't try this with AC. LOL
xD
Why would anyone even use AC?
Come on go for banks of capacitor.
Go for Photonicinductions big one
great project with lots of possibilities. There are power tool batteries from a hardware store that should match your power needs to make the project more portable.
Didn't understood anything but still liked the video because he did a lot of hard work
This is a cool idea for a build.
Great Scott!
nice tuts. I like ur workshop.
As always, great video
From your explanation demo where you made it fire by touching together the wires briefly , Made me think a simple momentary switch alone would function for the 1st coil .
Can you make a video about how to increase the power as you explained in the end how far would it shoot if you used the capacitor array
I like seeing you write with that fine-tipped pen
man , it's really satisfying.
Great video...
In order to increase kinetic energy what will you do? Increasing voltage or current? or maybe add more loops?
thank you
What a great video!
I learned a lot and if you don't mind, I have some questions for you:
1. Why IRS2001? Isn't it an expensive chip ($3)?
2. Is it possible (cheaper and efficient) to boost up the arduino mini's pin from 3.3v into 5v?
3. What would you do if you'd want to control 8x guns using a SINGLE pin (can fire one-at-a-time up to all-at-one, maybe TIP120?)?
Thanks!
just a thought here, instead of turning off the flow of energy at mid-point, wouldnt it be possible to reverse the flow, and therefore the magnetic charge to "push" rather than pull the rod and giving it even more boost?
hey, love your videos although I don't understand all the technical terms as i am not an electrical engineer. I wanted to suggest making a remote controlled small airplane like those drones but at a much smaller form factor. keep going !
Who's the best? ONLY GreatScott!
Can you build 6-digit nixie clock with old TTL's?
Wouldn't it be more efficient to place the sensors at the back of the coils because the magnetic field needs time to dissipate so if it's at the front the magnetic field will slow down the iron bar?
Will you make video about capacitor bank and IGBT that you mentioned in this video?
Hi Great Scott could you do a video on how you made the sign in your intro
OMG I proposed this video subject last time and Greatscott made it happen yyaaaaasss
I always wondered how many stages is required to get this into a super high velocity
Superb project again Scott. I wonder if you can detect the passage of the projectile past the coil centre electrically, by detecting a change in coil voltage or current? Ultimately you could remove the opto switch, but for now it could be valuable as a trigger source for investigating how the coil current and voltage change.
It would work much better to use a magnetometer or Hall effect sensor to do that. Basically, when the iron is in the middle of the coil it amplifies the magnetic field. This shows up as a spike on the magnetometer. Then use the spike and a delay to switch the magnets.
Nice Video, can you now pls make one, where you show how you shoot some stuff?
GreatScott you are genius
I took a few electronics classes a while back, I seem to recall that when you shut off a coil the collapsing magnetic field induces electrical current in the wire coil. Would it be possible to use the collapsing field energy to increase the power at the second stage?
"Those bullies won't bother me now!"
Hey, I have a new video out!
coil gun new test
czcams.com/video/TMsLIAmuuO0/video.html
Would love to test 30 stage version of this gun powered with capacitor banks
I'm never going to make one, but it's fun to watch xD
Loved it! I am a Physics student, Greatscott you made me interested to electronics. Thank you sir!
IR sensor problem can be resolved with an IR receiver/emitter setup. The issue with this setup, is that the emitter and receiver are in the same spot, which makes it so hard to fine tune. Material reflectivity can cause misfires.
If you have the emitter and receiver opposite to each other, it only depends on the projectile blocking the light ports on each side, eliminating the issue.
Is there a way to give rotation to the projectile similar to barrel rifling, only with the magnetic field? This would improve accuracy, distance and penetration.
Even though electroboom was good i love great scot for his explanation with practical ❤️
Can you please make some videos about the maths behind electrical engineering. eg determining the strength of coils or determining the efficiency of a circuit.
I made one of these years ago with the flash circuit from a disposable camera.
It's limited to single-stage, but you get a lot more power out of the high voltage strobe capacitor, and you can just wire the coil in series with the xenon strobe tube for switching (tube doesn't conduct until triggered).
I got mine to shoot little pieces of coat hanger wire across my bedroom.
If I added more capacitors to it (from more disposable film camera flash units), it's likely that I could have gotten it to shoot those pieces of coat hanger wire clear thru a soda can (maybe even both sides).
Best part? I got the disposable cameras for FREE.
Just go to a place that still processes 35mm film and ask them for some "junk" disposable cameras without the film.
Seriously, it's worth asking for those "junked" disposable cameras even if you only want the capacitor in them.
You can't buy something for less than free, and the worst they can say is "no".
Bank up a bunch of them and you could make some really dangerous high power electronic devices, like a soda can imploder or aluminum plate launcher.
To be honest, the hardest part to source for my "scrapheap coilgun" was the magnet wire.
If you can find a junked CRT computer monitor, you can probably salvage the magnet wire from the degaussing coil. Some CRT TVs might have a degaussing coil as well, but in my experience you're better off looking for a computer monitor.
If you want to build a big coilgun, the hardest part to source will be the thing that switches the current to the coil(s). Best bet is likely to be building your own triggered spark gap. Not too hard to do and can be done with hardware store parts and TIG welding electrodes as the spark gap electrodes.
using a flyback diode makes the magnet field collapse very slow since it limits the coil voltage to ~0.7V, many mosfets are avalanche rated so you can skip the diode and get
a much faster collapse by letting the voltage rise until the mosfet clamps it at Vbrdss
id like to know more about those MOSFET driver ICs so if someone can recommend a video or something that would be greatly appreciated
Nobody:
Me at 3 am : i goatha build myself a Rail gun.
Love this. I was into electro-magnetic propulsion for some time, but never studied to make such kind of -weapon- (well, let's not call it weapon, as that would be illegal, lol) launcher. Next time, make a Railgun. It's an easier concept to make (at least I see it to be more easy than a coilgun).
+GreatScott! Why is in datasheet of MOSFET driver written that supply voltage is 10-20V and you are using 9V battery, right ? It shouldn´t work, no? Thanks for quick answer.
Technical question - what to do to make it "more powerful" (projectile is traveling faster): increase the number of coils, higher the voltage, add more layers to the coils?
This is the content I want.
Awesome video!
what exactly did you study? i mean did you actually study in the field of electronics or you learnt all this as you went along?
underrated channel
Cool coil 👍😀
The time the coils need to be on could be calculated or expimentally determined. perhaps a dual 555 timer chip could replace the microcontroller logic. pots on the timer could fine tune the projectile velocity. Sound like a great AP physics project.
how u dint get shock with ur bare hands touching the copper on running voltage current im a newbie so explain in a way ill understand
By adding a spring in the back and taking off excess weight to the bullet you could've reduced the coil and input voltage considerably as well as putting limit switches instead of optical sensors
I've been watching a lot of coil gun videos for a possible project, and this is the best one. Great job. Although I gotta say that 3D print left a lot to be desired x-P! If you never got around to designing an upgrade and want to revisit it let me know I'm a currently unemployed engineer with a lot of time and modeling software!
if i used capacitors instead, do i only need to change the mosfets to ICBTs or something else??
This project is cool.
