if you have bigger caps use a longer coil

No a shorter one to discharge them faster.

hey do uknow anyway to make it without capacitors can u make one cause i read that capacitors are very dangerous please reply

Yea dengerus if your stupid and stick your fingers around wen there charged.

I once acsidetaly was toching the output wen i trigerd the SCR and it only stung a litle bit.That was 100V.My hands ware dry so codnt coduct much.If they ware wet i wod cetarnly get a painful shock.

There is a way by stacking a lot of car baterys in sersis to get an high volatge.This is very dengerus if you short it becose an cap will only make an pulse of high curent but a car batery will make continues high curent that can make wires realy realy realy hot and melt them.

Whith an coligun you have to have high volatge to get enugh curent trough the coil (Ohoms law)

ok i have one more question since a transformer and doubler both magnify voltage couldnt i just use more than one of those

You cant stack transformers one after an nother.But some voltage multiplyers can.I dont recomend this becose as you multiply the voltage you decresre the curent and therfore the caps take longer to charge.

I have an mains transformer that outputs 50V but i neded 100V so i put in an voltage dubler.

the thing is i dont want it to store energy then do more then 1 shot i want it to cut of every time the switch isnt on i know itl take some timing but its ok like that

Then you need a bunch of car baterys and an realy big MOSFET.

I think you could make the weapon more powerful with little difficulty, i think that if you use a slightly longer pipe and 2 seperate coils (with a reasonable gap between them) one fired after another then you could gain more speed.

the first coil needs to turn off before the second turns on, the first one should get initial momentum in the projectile and the second one should boost the speed.

if you try it then let me know how well it works.

Someone Electro

I know thats called an multistage coilgun.You can have an open or closed loop desing.Open loop is just an timing circuit fireing the coil one after an nother.An closed loop has feadback.there are LEDs and phototransistors in the barel to detect at exsactly what moment to fire it.

any one thought of making a rail gun out of the same circit without the coil

i know the basic principals and you can shoot ally plasma acroos a room

I already sean that site.
but thanks anyway

can u please give me a layout diagram or a more detailed ckt diagram?
im not as good as youll in electronics.

Someone Electro

You have all the information you need.

If you know so litle you better stay awey becuse a coilgu means dealing whit high volategs at high curents.
