This homemade railgun is both awesome and frightening at the same time!
An electromagnetic projectile launcher, or railgun, has generally been the thing of military testing and prototypes.
But these guys apparently built a homemade one. The result is one wicked-looking do-it-yourself project. Just check out some of these videos to see it in action!
Imgur user Zebralemur says in his post that the rail gun is the most powerful one ever made by a non-government entity. He said it took him two years to acquire the expensive, 400 volt, 6,000 microfarad capacitors for the device at a cost of around $2,500.
I was surprised when he revealed late in the post the projectiles are only traveling around 50 miles per hour. It looks much faster than that.
He also included detailed instructions for how he constructed the device, although he doesn’t recommend it.
“I am providing information on how I created this project, but I cannot recommend anyone to try this, EVER. High voltage capacitors are extremely dangerous. High speed projectiles are dangerous. 9-volts are dangerous. Nothing in this project can be made absolutely safe,” he wrote.
