2 stage coilgun

A early multistage coilgun i built i while back.
In this video only 2 stage of 3 is functional.

i am attempting to make a 4 stage one but how long should the coils be because i know thats important

[LaRdArms]

The length of the coils is the same as the length of the projectile.

The coil itself is more important so you get the correct pulse-length.

check out my video on second stage sensor. It would show you how I would make it

You do this with the help of a light barrier ... to learn more just google it.. ;D

Pardon me, I know this may be a silly question, but I was wondering:

How does one get the coils activated in sequence in a multistage coilgun? What device did you use?

[DirtyJihad]

very silent. I would like to see one of those coilguns shoot a full soda can. You could shoot it through a hole in a board, and block soda from spraying the gun.

**ignore the already**

I got the caps for about 7usd each, pretty god i think :)

I now the power-labs site and i already built a smaller one and i think i now how to build the big one.

DAMN WERE DID U GET SUCH CAPS and also i sigjestlooking at powerlabs railgun they will show u what to do and how to do it

[LaRdArms]

The coils is calculated to match the capacitance of the capacitors, if i added more inductance to the coils the pulse would be to long.

Now iam planing to build a new railgun, just got 24 15000uF 400v capacitors, they will make a nice 28Kj capacitor bank. :p
