My 330V 78Joule Coilgun

About: “Let the future tell the truth, and evaluate each one according to his work and accomplishments. The present is theirs; the future, for which I have really worked, is mine.” Nikola Tesla

I built this for a school project faire. It has slots for different size coils so I am not limited to one barrel. It has a custom built control box with: Power, HV in, 2 switches to control which capacitor bank to charge, and a firing switch... As you can see I also made the power supply too. I bought the metal case at fry's electronics down in burbank, CA. It has a power indicator and charge indicator LED to tell when the capacitors have reached maximum charge. It takes about 30seconds for one bank to charge. Each capacitor bank consists of 6 330VDC 120uF flash capacitors.

    "sparky" can be charged with a camera circuit as long as you hook it up to a voltmeter to make sure it doesn't overcharge.

    lol. same handwritting as mine. however you could have used acrylic sheets for more aesthetic view. nice control panel awsome. a better work could have been done with your coil. what type of wire did you use

    yeah that was a typo, sorry about that :) And yes, 500V at 5 amps will be EPIC! I am almost done getting all the parts together...

    300Volts at 0.16amps (16ma) wich equals to 48 watts.. Its not much I know but its only 1 flash curcuit, Im actually making a new charger that can handle 500VDC at 5 amps, I also bought some giant 2400uF 500WVDC capacitors too. I will post some pics later.

    I don't know exactly but its less than one.. I will get my ampmeter out and test it...Along with the watts, how do I calculate that??
