Check out the cool coil gun projects at Another Coilgun Site. Near the end of the video you will see the coil hand gun! This thing is computer controlled using a microcontroller for enhanced operation.
“At last!! A functioning example of the combined wants in a coilgun pistol. You always see posts for this and that, read how if it could do such and such and the inevitable plans on doing whatever.
The wish list follows.—
“Fast Charger and be small enough to fit in a pistol”, yep. “Charger automatically charges upto the voltage I want, stops, then regulates”, yep. “Controllable fire sequence, I want to use a computer to test by adjusting on/off times to the microsecond”, yep. “Holds a magazine and is retractable along with a retractable battery power source”, I say yes to this too. “Dual energy shot levels, full power and partial power, by charging to a lower voltage and loading a different timing sequence”, yes and you need but to flip a switch the pistol will handle the rest. —These concepts have now evolved into a physical reality.”

wow, way to take 3 cuts of shooting the pistol and jam them together so it looks like u actually can shoot fast

Just my two cents on the recoil subject. I’m an engineering student so I have taken a few physics type classes.
F = Ma – Force(recoil you will feel) = Mass*Acceleration.
a = dv/dt – acceleration equals the derivative of velocity.
F= M(dv/dt) – Substitute.
F(dt) = m(dv) – rearrange and integrate.
I’m assuming that you will know the mass of the projectile and speed you want to obtain. So for this I’m going to pick a mass of 10g and a speed of 100m/s. From the video shown it takes no time at all for the projectile to be brought up to speed so lets assume that the time is 0.1s.
So the limits of integration for dt are 0 to 0.1(s) and for dv 0 to 100(m/s)
After integration you get
F(0.1(s) – 0) = 0.01Kg(100(m/s) – 0)
F(0.1s) = 1Kg*m/s^2
F = 10Kg*m/s^2 or 10N – Its not alot and its been a long time since I have done this type of math so I might be wrong, and if I am please correct me. If you know the mass of the projectile and time it takes to accelerate the projectile you can find the recoil.
Hope that helps – Now I gotta start building one of these.

how did you make the first one?

How meny volts/amps that coil is using on that video and i mean
just that coil not the gun !?
