    I was thinking bout a magnetic/ electricity powered slingshot. I love the potential for electronics based weapons, so why not a slingshot?<br><br><br><br>The simplest conception would be coils of copper wire around segments of iron cores. When current is applied to these, the cores become electromagnets and they attract rapidly. If an iron core 1cm in length can attract antoher iron core 1cm in length from a distance of 1cm then a series of ten of these cores will have a draw length of 20 cm, contracting to 1 decimeter. These numbers are only place fillers.<br><br><br><br>The construction would be quite easy. Coils of wire around some screws or ingots each wired in parallel to a battery pack. A switch energizes the circuit, and de-energizes it. illattempt to build

    i have been thinking about magnet powered weapons to and they already excist though theres this cannon wich uses electromagnets to shoot rockets faster then anything else in the world can

    The above illustrate a simple proof of concept illustration. The idea is to use magnets, or electoromagnets in the ultimate application to provide the power for a slingshot. My own work on the electromagnetic slingshot hs been put on pause for this demonstration, and because the stainless steel bolts I had did not make good electromagnets. I am experimenting further. <br><br>The first and second pictures are of relatively weak button magnets hot glued to a cutting of grocery bag plastic. The bag plastic is so flimsy the magnets are even too difficult to work with in finishing the project. Success! This assembly demonstrates proof of concept. In the second picture look as I try in vain to pull the magnets apart to finish gluing! Do you see how pulling these magnets apart and realeasing them could fling a projectile<br><br>e third picture are of relatively weak button magnets hot glued to a piece of ribbon. The idea is to encircle the magnets with ribbon so that the entier assembly becomes "elastic". As you can see the ribbon is too rigid for this application. The magnets are too weak, neodymium magnets may work.<br><br>The fourth picture are some tools and materials.

    You mean a Gauss-Rifle or Coilgun? They do not work yet, not even most prototypes, but it can work out, totally.
     
  10. It has a coilgun or railgun in it, I believe he is going to use that effect to "cock" the slingshot.

    Another arrangement could be a "linear motor" type cannon, that is F=BxI ... a "barrel" where a series of magnets points the same direction let say up/down and a pair of perpendicular copper contacts along the barrel that provides the discharge current of a condenser bank through a switch (a high capability mosfet) that traverse the ammo ... I think that would be easy an reliable because of the absence of shocking magnets and a smooth and constant acceleration ...<br>

    i saw <a href="http://www.youtube.com/watch?v=yMoIExJEaBU" class="postlink" target="_blank" rel="nofollow">THIS</a> on YT but there was another vid that i can' t find no more, the guy was really launching steel balls but i am no sure if it was with (electro) magnets, chain reaction or just with his thoughts,... I am not a physics/scientist kind of guy <img src="http://illiweb.com/fa/i/smiles/icon_neutral.gif" alt="Neutral" longdesc="20">

    The US Navy has working prototypes of this kind of gun. They are great for ships because the ammo doesn't need propellants which are a huge fire hazard on board of ships, especially warships. It requires truly massive amounts of energy, though, and it is very difficult to get it right.

    <div>Just type "coil gun" in youtube and you'll see many prototypes of that... but to obtain the power of a real weapon you'll need huge electrical power, and heavy material. Anyway don't forget that today, nothing is more efficient than gun powder to shoot a bullet, and the simplest but still efficient weapon is the "rubber powered slingshot"...</div><div class="clear"></div><div class="signature_div">

  17. You guys should youtube Metal Storm.... I think you'll get a kick from it.

  19. Not grenade launcher, it shoots bullets. But up to 1,000,000 a minute. <img src="http://illiweb.com/fa/i/smiles/icon_twisted.gif" alt="Twisted Evil" longdesc="13">

    <div>do not believe all that you can find in youtube. Metalstorm is an american compagnie which produce real weapons. May be some game designers can also use that name for their futuristic weapons... <br><br>also consider that the number of rounds per minute is theorical and for a gun's magazine of 100 at high rate the shout will be 1 second.</div><div class="clear"></div><div class="signature_div">
