An engineer has a railgun that on Reddit shown. A railgun is an electrical gun that with the help of magnetic fields are projectile accelerates instead of using gunpowder. The rifle fires bullets of tungsten, aluminum, carbon and teflon.
The majority of the components of user NSA_Listbot are WXPR-railgun come from a 3d printer. Only the important parts such as the loop, the capacitors, and the injection system have a different origin. The 1.1 gram projectiles of this railgun move with a speed of 250 meters per second, what subsonisch and in most cases not lethal.
Although a railgun has the potential to be more powerful than on gunpowder-based counterpart, such as in the U.s. navy to see is that this rifle so not the case. To achieve that, is a larger source of energy than a battery. A nuclear reactor powers the railgun of the Us navy, for example. A railgun that is both portable as fatal, is on this moment not yet practically feasible.
NSA_Listbot says a year and a half have been busy to be with his creation. The rifle weighs more than twenty pounds. About half of that weight comes from the six capacitors where the electrical energy is stored before the fired. That capacitors in the loop is processed in three rows of two.
The power is supplied by a driecels lithium-ion-polymer-battery of 12 volts. The energy of the battery is transformed up to 1100 Volts and 1.8 kilojoules of energy. An Arduino Uno R3 keeps voltages, ampèrages and temperatures in the holes. To the projectile between the rails to get, used NSA_Listbot a CO2-injection with a pressure of 300psi.
After three or four times fire, the battery is empty. The inside of the rails is after about ten shots worn. Room for improvement is there according to the Redditgebruiker; it is estimated that 2 to 5 percent of the electrical energy is converted into kinetic energy. In a gallery on day gifts is the luchtvaarttechnicus in detail the construction process of his railgun, and in the posting on the diy-subreddit answer questions of other users.
All the grey parts come from the 3d-printer, that thirty days continuously had to print everything in order to produce
