Simple rail gun

Simple rail gun type thing i made whiles ago. was operating more smoothy before friend nearly destroyed. using coils from 12vdc magnets, a uln2803 or such driver, and a 7404 inverter (as s/r flipflop)... As the metal panchinko ball touches the rails, made from house wiring, it switches which magnet is active. All held together with the hot glue. Easy eh? :D

So does this work by the coils attracting and repelling the ball, and is the ball magnetic

@iwan0t0smith ball is not magnetic, is from pachinko parlor... there is only attraction no repelling :p

No, I think it was just proof of concept, not sposed to be a real rail gun

[ForbiddenMagic]

tbh i happened to see another device on here made similarly that was labled 'rail gun'. It did not go back and forth just one direction maybe thats the difference? @_@

hehe

[suupertramp]

when you say in the title "was operating more smoothy before friend nearly destroyed", does that mean your firend was nearly destroyed, or your friend nearly destroyed it?!

[ForbiddenMagic]

haha, no one was almost harmed... just bend it and broke some pieces.. all good it was built pretty fragile ^^

thats not a rail GUN, it's just the "mecanism" of one.

[bahamut1993]

A gunpowder projectile releases one large impulse, though, while a rail gun applies the force over a longer amount of time. The recoil is still there, but much easier to compensate for.

(this x 10(power)) + rail 180º = mFk Railgun!

Gauss gun, railgun, coilgun, essentially identical.

[flamedrag18]

this is closer to a guass gun then a rail gun.

[Delid]

Attraction, no repelling. I guess that's because of the gravity of the ball coming back down the hill that makes it go back and forth?

This is neither a gun nor is it related to a coil-gun. It's a bend rail which operates by techniques similar to a gauss-gun which is totally different.

[LuigWollknaeuel]

this thing is called "Gaus-Gun", not "Railgun".

You disgust me by posting videos in which things are not what you say they are. YOU sir, are a ham sandwich!

[brandonhughes7]

weres the gun in that its just a rail

[freitasnetuno]

Fail Gun

[allmotorhash]

do this would make guns quite
