Select fire gauss gun

[cabinetguy]

awesome. I see someone with a DOD contract soon

He should use ball bearings instead of those projectiles because they are tumbling, comment I saw on YouTube "I can imagine this getting into the wrong hands and killing innocent people" smh stupid antis just don't want progress smh

Perfect as a shotgun...maybe steel shot 410, yes?

I recall the rail gun concept and to replace a 20mm projo you needed enough power to run the city of San Diego stored in capacitors.

Maybe new technology has fixed the power issue.

Caseless ammunition will probally come sooner.

rail guns with current tech takes too much power.

This would really be a cool shotgun! Seriously I would buy one lol you know a little bit off topic but you know how he mentioned that the electro current moves the projectile forward? What if cars on the freeway where like that. No wheels or anything just magnetic force pushing them forward at high rate of speeds, won't it be safer and more efficient for people to get to work like that. Like the actually freeway will be a magnetic conductor and the vehicle the "projectile"

Would have done better to work with BB's.

Maybe when I've got some free time to work with ...

Coil guns and rail guns are two entirely different concepts.

The design is non-optimal due to his projectile length. A coil gun pack only pulls to it's center. Each coil optimally is designed to trigger and rise to full strength just as the projectile is entering the beginning of that coil. It then needs to shut off before the projectile cross the center point of the coil pack or the magnetic forces will act as a brake on the velocity of the projectile.

It is more efficient to have a gap between acceleration cycles representative of 50% of barrel length than it is to have a projectile cross the centerline and start to be slowed.
Unless you are using some of the very advanced designs as currently used by the government a coil gun is limited to a 50% barrel length acceleration cycle.

No reversing the poles on the packs do not enable you to overcome the 50% limiter, a coil pack pulls from both ends towards it's center point.

If I still had a working brain I could whip one up for you guys.

@Peter, I still have a 2000 amp solid state relay if you need it, worth about 1200 bucks.

Yeah that would work great if you only put one car on the road at a time.

Might be interested in that at some point.

I think I'll probably do a railgun before I do a coilgun, but I could probably use a relay like that in switching either setup. Could get a REALLY long acceleration out of a railgun with two cap banks ... hmm ... flux drops from the first one, trigger the relay and fire the second ...

gotta think about this one some more.

Needs more power. I'll be interested when they shoot it at a range because its to powerful to shoot inside a house.

I got it years ago and used them in a few of my projects. I used to have more. Lost more than a few to catastrophic failures of a few of my designs that were way over energized.

I've got one left now and it's been gathering dust. I have been having a hankering for some high energy projects again but my mind just isn't working so I am out of this game for the foreseeable future.



Also have some fiberoptic controls and fiber and some optical switches, fairly fast ones.

Needs a Mr. Fusion.
