Here are some pictures of the nearly completed prototype. Each of the custom parts were printed in ABS plastic using a Dimension 3D printer. All of the parts have been cut and drilled according to the plans. The only portion of the project remaining before completion is the insulation of the outer walls of the […]

Here you will find the design, computer animations, stress analysis and other useful information on the design of the railgun. All of the intricate plastic parts in each of the later revisions were modeled using Inventor Professional 2011 and will be printed in ABS plastic using a Dimension 3D printer. Mini-RailGun ANNOTATED SKETCH COMPUTER ANIMATIONS […]

This is an electrolytic 400 vdc 12,000uF capacitor capable of discharging 960J of energy. It is approximately 12″ in height with a 3″ diameter base. Discharge onto a 1/16″ aluminum plate. The discharge left two vaporized patches, each roughly 1″ in diameter. Discharge into a 2″ cluster of steel wool. Discharge onto four layers of aluminum foil. Videos of […]

This is a 250,ooo volt tesla coil. It is powered by a standard 120 volt 60Hz US plug that powers a neon sign transformer with an output of 6kV at 30mA. The transformer is wired in parallel with two 10,000 volt capacitors for a total capacitance of 10nF. A pure tungsten spark gap is wired in series with the […]
