ion ray gun Answered

remeber a while ago I said I wanted to make some cool high voltage weapon in the shape of a gun? Well I've dicided to make an ion ray gun! The only problem is that I don't want to pay for plans (that's just not right, half the time they probably jip you). The closest thing I've found is this:
but that doesn't help me with saftey procosions (sorry, having a bad spelling day).

Basically I need help for the schematics and the safe way to build and handle one. I don't want a wimpy one either, I want a medium power one, like do stuff from 10-20 feet or something like that.

Oh and if possible, skip extra circuits by using something like this:
I also don't mind making voltage multiplier circuits.

If everything works I'll make an instructable out of it!

Oh, and tech-king, you can use the sign now.


you can find it here


could you go to goodwill or something and get one of those ion air cleaners and use the guts to make an ion gun?

I don't think it's illegal, all it is (correct me if I'm wrong) is a really high dc voltage pulsed through a sharp object emitting ions? for all of you saying negative ions don't make you better, here's reason. Negative ions speed up the cilias in your body, making everything work faster and stronger or something like that.

negative ions are very good for the immune system.

I know you're right, but that sounds funny for some reason. "The doctor says I need more negative ions, blast me!"

can you please explain to me why you picked something as useless as a ion canon? a much better choice would be a rail gun.

I don't want something toooo dangerous. Rail guns are nice and all (I was about to make a coilgun, which is awesome too) but I mean it's just... uhhh. more so useless? Like you couldn't do as cool demonstrations with it. Big woop it shoots stuff, but an ion ray gun is invisable stuff, so people are like wooahhh

no. 1) an ion gun display nothing. no one sees anything. for all they know, its not working 2) reverse the last diode in the link i provided 3)your demonstration will be boring, as there will be nothing to see 4)a coil gun is a better plan 5) ill think up more reasons why this is a bad idea later. i have an electronic pessimist meeting now.

Hmm, you "could" move small bits of paper, or packing peanuts, with it :-)
Kind of like "air" from a solid object *shrug*

I here you can do other cool stuff with them, but I havn't been able to fin a reliable source on the net (everyplace says something different...)

you can put your finger near the discharge probe. that would be cool, but short lived (get it?).

You could charge someone from a distance, watch their hair stand on end, then drop as they give someone a shock...

and i here you can charge caps from a distance.

thats a tesla coils job. if you insist on making an ion generator, ill give you some real schematics. but i still say it is a bad project.

I wondered why they encased the one I have in tempered TAR like plastics (the electronics I mean)

your what? tesla coil or ion generator?

Ion Generator. I had 3 of them and took one apart to see what parts they used.....that was a useless endeavor.....all the electronic parts were encased in the semi-hard, almost tar-like black plastic "stuff". I have t 10,000 vDC power supply.....same thing, nothing viewable, sigh

Maybe other wise it'll spark between caps?

probably potting material to prevent internal shorts. guyfrom7up, i have a circuit here for a positive ion generator. do you still want it?

sure! Can I some how make it negative though? Or maybe I'll just shoot it in my enemies window and make them feel lousy... mwahahahaaa lol.

oh, and by the way I'm getting dangerously close to the edge of my screen, lol.

okay. ill post it when i finish my homework. but decide: positive or negative. negative is much easier to build, and will help you forget the wrong your enemy caused you.

Also can you email me both? my email is gamarlie@hotmail.com... i'm making an ion thruster, and i need an ion gun or emitter both negative and positive will work thanks

It is not a real good idea to place your email address out on a public forum like this as spammers will harvest it and send you lots of mail (but not on your requested subject).

sounds good. ill have it up around 7-8 o'clock atlantic time.

sweet, thank you solo much. I'll post a video of it when I'm done with it (I've never seen a video of one before). Or do you not recomend that I record It because it could fry my camcorder.

not sure. with it off, you could make a video of it. on, i would not point it or the stream near electronics.

Ions are pretty small. Are you going to use an electron microscope to record them leaving the cathode?

I was actually going to Try to fire it at my free energy instructa me and see what happens. Then go get some cheap electronics from the dollar store.

"firing" it into a "fog" or smoky environment might be interesting (or not) :-)

Hey can you email me the circuit or blueprint in making a positive ion generator ? and explain how to make an negative ion gun or emitter

Well, one would certainly move a "floating" balloon about (another "air" without a hose application). Making little pieces of things (paper, Styrofoam, etc) "dance" (jump back and forth between two points, etc)....I have done a few things with HV electricity (they also tend to "clean the air" which means that dirt "sticks" to what ever is near the ion generator *sigh*

ok, quick question about voltage multipliers What's the rating of the voltage of the capacitors and diodes? In the HV capacitor multiplier instructable the person used lower rating capacitors than the output voltage, and lower rating diodes. what's the minimum voltage needed for each cap. Variables are good to, like V is input volts, 2V is the first cap rating, 4V is the 2nd cap, 2.3V is the diode, or stuff like that.

1) caps and diodes must be rated to at least 2xVinput
2)smaller cap value=more ripple (sure i said this to you months ago)
3) if you use a v multiplier, use the circuit below, but YOU MUST REVERSE THE DIODES!!!!!!otherwise, you get positive ions.


thanks for the clarification about the cap and diode ratings, that helps a tremendous amount (and here I was looking for really high voltage diodes and they were like 20 bucks a piece, lol.)

you do need one high voltage diode for the actual generator. and make sure you reverse the diodes in the drawing i gave you. and if you make an instructable, will you mention me?

you betcha, and if the particle accelerator thinhgamajig works I'll say patriki helped me with that. where does the HV diode go?

D1 on the circuit diagram for the actual ion generator. it needs about 1000 volts peak inverse voltage i believe. make sure the fan is plastic though.

thanks! Patrik says to use positive ions, then neutrulize them

that should work. you asked for a negative ion generator. i didnt know you were using screens. if you want positive ions, reverse d1

If you want to create an ion ray gun, then a high voltage ion source is only the first step.

Once you've generated your ions, you will also need to accelerate them! Otherwise you just get a cloud of ions that sits there and creates sparks.

One approach is to accelerate the ions towards an electrode of the opposite charge. Now, if that electrode is a conductive grid, most ions will actually miss the electrode, and fly through the holes in the grid. If you now put a second grid electrode right after the first, with the opposite charge (i.e. the same as the ions), through inertia most ions will actually fly through *both* grids, then be further repulsed away from your ion gun by the second grid.

Welcome to the wonderful world of particle accelerators! This is actually how most ion thrusters work, like the one that the Deep Space 1 probe used to do a comet flyby. Electrostatic linear particle accelerators like these are some of the simplest designs around, and might be within reach of the average high voltage amateur...

thanks for the additional info that I didn't know about! now can you dumb it down a notch? lol, I don't really get the whole grid and jet propolsion thingamajig

Sure -

Let's say you're producing positive oxygen ions. Opposites attract - so positive ions are attracted to a negatively charged electrode. You can calculate what force the electrostatic charges exert on the ion, based on the potential (voltage) of the electrode, and the distance between the ions and the electrode. As the ions fly towards the negative electrode, they will pick up speed.

Now, if the electrode were a solid plate, the positive ions would just smack into the negative electrode, and at best you'd see some interesting radiation from the collision. However, if the electrode is a grid of fine wire, then many of the ions will have picked up too much speed to make that last course-correction to hit the wires. Because of their speed and momentum, they will actually miss the wires, and shoot right through the grid. Kinda like an incoming comet which is attracted by the sun, but skips past it because it's not on the right trajectory to slam right into it.

Now, if you only had that negative electrode grid, your positive ions would just zip back and forth through the grid a few times until they hit a wire. The clever bit is to put a second, *positively* charged grid right after the negatively charged one. If the ions are moving fast enough, they will actually zip right through both grids without too much change in speed or direction. But once they're through the second, positive grid, the electrostatic charge will repel the ions, and push them to keep going in the same direction, rather than fall back onto the negative grid.

That make sense?

something like this? (for a negative ion gun) I was too lazy to draw everything properly on my cad software, so I wipped something up ina minute on paint.

ion gun.bmp

huh, the picture's kinda tiny, well the scribbles are a high voltage (+) wire net in front of the hgih negative voltage nail (sharp looking thing). They are far enough apart that it doesn't start sparking. Everything will be enclosed in a pvc pipe (Correct me if I'm wrong, is that an excellent insulator, or a terriable static insulator, bottom line, would it be good for making a case out of then painting it so it looks all cool.)

You'll need one more grid: - negative ion generator - positively charged grid - negatively charged grid right after that (i.e. just to the right of the positively charged on in your figure) In practice, you'll probably want to use positive ions, and inject electrons into the ion beam to neutralize them. Otherwise, if you're flinging away a steady stream of charged ions, you will wind up collecting a massive electrical charge on the ion gun - and the idiot pulling the trigger! ;-)
