- I finally finished it!
A gun that uses electromagnets to accelerate an iron bar. In the future, I'd like to build another one that has smaller & faster projectiles (20 - 30 m/s). I'd also like to see about making the projectiles fin or spin stabilized.
If you guys want, I'd be happy to share my models, code, and schematics. Just let me know!

That should be powerful enough to launch a mini projectile and incredible speeds
Sick man. Looking forward to your progress on the home made ferrite core!
I've been delayed on that project for a while. I wasn't getting significantly better results by casting the ferrite under pneumatic pressure. So I think the best path forward is to use an arbor press and dies milled from aluminium. The issue is that I've been waiting for months for my nicer CNC mill to arrive.
Good shit
Cool cool cool
This is so cool
Thank you!
By putting a magnet as a projectile and then changing the timing by adding traction with the propulsion. Is it possible to do that? 🤔😁
Next step is to make a rail bazooka
Can I buy this thing off you? Lol I don't have access to the tech but would like to reverse engineer some things when I have my funds in order. I'm more interested in propulsion than weapons but still see a use of a "rail gun" and your model is solid. I do however have concerns for the capacitors durability, they can be more dangerous than the projectile. Cool video
Это круто! 👍
Hello! I want to build my own coil gun. Could you help me with the details of the project (code, parts, schematic, programming, etc.)? Thank you!
Hey there, I am currently planning my own coil gun build and I would really appreciate it if you could share with me the details of the project (Code , Parts, Schematic etc) . It can be really helpful to me to see how another build works and ticks
Sure! Just hop into the discord linked on my channel. There are literally like 3 or 4 of us that are going over design ideas for coil guns in there.
Man, pretty cool. I'm plenty curious about this, but I'm sure just about any question I ask I will probably not know enough about any of this to really appreciate or gain anything from any answers you'd give me. I know I've asked before, but why is multiple coils better than just 1 really big and or long coil?
The field strength decreases with the inverse square of the distance.
So if we're 10mm from the center of the magnetic field generated by a coil and we're experiencing a field strength of 1 tesla, at 20mm away from the center we'll be experiencing 0.25 tesla.
So having multiple short coils means that we get several big & quick pushes, rather than the weak and slow one we'd get with a big coil.
There's also the problem of a bigger coil having more wire that the electrons have to go through to get to the other end, which means higher resistance and less current. And a coil's generated field is directly proportional to the current flowing through it.
Additionally the coil is fired using capacitors which quickly drop in voltage as they discharge into the coil (corresponding with the inductance of the coil and capacitance of the... capacitor). This means that a really long coil would not only take longer to discharge through, but the capacitor would quickly drop from it’s peak voltage by the time the projectile came closer to the solenoid
Hey dude, I am currently just entering learning about electronics and would like to build a coil gun myself. Idk if you would mind sharing the parts list and possibly even helping me with some instructions.
I'd love to help! I sent you an email.
I am not sure why I can't find it anywhere, but how does the voltage affect the magnetic fields and projectile acceleration?
The current through a coil is proprotional to how strong its magnetic field is. If you double the current, you roughly double the field. Increasing the voltage is what causes more current to flow through the coil since Amps = Volts ÷ Ohms.
Why such a long projectile?
1:11 ngl i was expecting you to take a huge bong rip and not explain how a coil gun works😅
Which mosfets did you use?
IRF1407's
@@BenjaminMarshallScienceMan Thx
ough. how much
Look like a Half-Life gun
can you send me the models, code, and schematics via discord?
Yeah, just message me on there and I can send you everything Papa Marsh#7490
