A Gauss gun, also known as a coilgun, is generally something that people think is confined to the world of science fiction although the working concept has been around for a while. Jason Murray of Delta-V Engineering has come up with his own home-made take on the coilgun, posting a video of the weapon in action.
The initial stages of the video are just a closer look at the Gauss gun as well as an overview of how it works. The small metal projectiles are propelled up the barrel by a series of electromagnets, eventually leaving the muzzle at a maximum rate of 7.7 rounds per second.
Murray’s weapon takes on cans, glass jars and, eventually, a laptop in full-auto mode. The gun doesn’t appear to be able to fire projectiles perfectly straight as some of them can be seen flipping before or during impact. At least it wouldn’t look out of place on a mission to Mars to take down an alien menace.
