    Machining can be done with a file, this is largely how Khyber pass guns are made.

    Give it up already.

    Have you collected all the dragon balls?

    You can tell from the video that is not possible.
    1. They would go right through the laptop and the rest of the building.
    2. They would have made a sonic boom/crack, like even the lowly .22 does.
    3. What magic power source would do that?
    4. What magic coils would power up that quickly?

    You should just admit you were wrong.
    Stens are one example of an open bolt automatic that are easy to build and do not require precise moving parts.

  5. Re:Smaller projectiles? on Building a Full-Auto Gauss Gun · · Score: 1

    How fast can those coils run?

    My guess would be he is near those limits so a lighter projectile would not travel much faster.

    You don't know what firing from an open bolt means do you?

    It means that the firing pin is part of the bolt face or fixed onto it and the bolt slamming down on the round is what fires it. In most simple designs the bolt is then thrown back by the round discharging. This design as you can likely now guess vents a lot of heat and as such tends to avoid overheating.

  7. Re:It highlights some of the legal issues on Building a Full-Auto Gauss Gun · · Score: 1

    Actually it is totally legal to sell the gun, so long as that was not the reason you built it. So if you build a gun, and get sick of it a few months later you can legally sell it. This may not be legal in your state though, I am speaking only about federal law.

    This gas gun does not have the potential of firing lethal rounds. The speed of expanding gasses is a heck of alot faster than this thing will ever propel a projectile.

    9000 fps cannot be right.
    That would make this thing supersonic.

    At 9000fps these nails would go through the back of his garage, not be stopped by a laptop screen.

  9. Re:3% velocity on Building a Full-Auto Gauss Gun · · Score: 2

    Physics?

    You need a ridiculous amount of current, you need coils with a near instant rise time and you need switches that flip instantly. Good luck.

  10. Re:Sensationalist summary at all? on Building a Full-Auto Gauss Gun · · Score: 4, Informative

    Why would you think that?
    You can make a fully automatic submachine gun of the open bolt design out of stuff you can find at home depot.

    I understand that feeling.
    Back then I never thought we would have "Papers Please" stops in the USA either.

    Terrifying, this flings nails not quite as fast as a young child could through them.

    I don't think the cat will live that long.
    I would assume any animal that lives multiples of that should be able to do so. I can recognize voices I have not heard for a decade. Why would animals that have such long lifespans not be able too? I would have been more surprised by the opposite outcome.

    Or you could realize we elect a president not a dictator. There are a lot of other folks involved, nor would most of the other candidates done anything differently.

    I think you will find the NSA and the UK intelligence assisting each other is really "A favor for a favour".

    If my cat can remember the sound of my car I would hope a dolphin could do this.

    At least that is an attempt at treatment. I am speaking about someone dying because they had to decide between a painkiller and an antibiotic.

    In the USA if left to the states the whole middle of the country would have no health care for those that could not afford it. Neither would the south.

    Quake 4 was not terrible. Rage was a bit of a let down though. the ending was bad, the open world driving was pointless. Had it been sold as a new dungeon crawler it would have been fine, but it tried to be something it was not.

    Sure, but that is because we will spend any amount to stay alive and well. It cannot be a rational market. No matter the cost if you could make my tailbone like it was before I broke it I would pay that.
