THE GAUSSIAN RIFFLE
The electromagnetic riffle is a weaponry designed to fire ferrous projectiles with the help of high voltage currents discharged from a capacitor bank. It is a simple riffle designed to reduce the complexity and cost of bullets . The riffle is based on the concepts of electromagnetic levitation and magnetic propulsion techniques, the basic idea is that when a solenoid is magnetised, its core has the tendency to pull any iron projectile in to its core
If the current to the coil is stopped before the projectile reaches the core then the projectile travels with the same high velocity in the same direction it was pulled towards its core
If the current to the coil is stopped before the projectile reaches the core then the projectile travels with the same high velocity in the same direction it was pulled towards its core
You Will NeEd
To construct this riffle you will need a 25 cm long pvc pipe, 0.5guage magnet wire, a switch ,a rectifier (4 diodes) and lots of capacitors(higher the capacitance higher will be the power )
The Cannon
Attach the disks as shown in the picture and wind the coil over the pvc tube between the disks as shown adding a connector may do great help. THe disk helps to converge the energy where its required , it optional.
THE STAND
Having a stand like this (made out of foam) to make the riffle nice and sturdy is essential .it gives it a look and keeps the riffle pointed always, (ts optional ). The riffle is now constructed . we have to design a capacitor bank to fire it.
THE CAPACITOR BANK
I have used a 500 mfd capasittor for this .I get a potential of 470 volts when my capacitors are compleatly charged. the discharge from this bank is used to fire the projectile.Itis discharged with the help of a switch (10amps 450 volt). the current lasts only for split seconds .and hence there is no need for high speed switch or relays to supply the required power to the riffle
THE CAPACITOR CHARGING UNIT
I have used a bridge rectifier to charge my capacitor bank. it has four diodes in a loop the output from this rectifier is pulsating. but it is perfect for the capacitors
THE SET-UP
THE FINAL SET-UP LOOKS AS SHOWN IN THE PICTURE now the riffle is ready to use. remember we need the discharge from the capacitors not the main source to power our coil so switch off the mains when the capacitors are charged and then press the fire button.
Projectiles
the riffle can fire any ferrous projectile , it can also fire ball bearings
SEE IT IN ACTION
THOUGH THE POWER FROM IT MIGHT SOUND INSIGNIFICANT BELIVE IT OR NOT I GET SPEEDS UP TO 2M/SEC IN MY PROJECT AND IT IS CAPEABLE OF OBTAINING UP TO 350 FEETS PER SECOND IN MODELS HAVING 20000 MFD CAPACITANCE
