Introduction: Nerf Maverick "air Taser" for $25

Picture of Nerf Maverick "air Taser" for $25

So I was in Walmart and I seen some Nerf guns and just across from them was some bike tools, so I got the idea to make higher powered Nerf gun that could fire a capacitor. This is a quick method and now that I've done it once I could redo it in about 10 mins start to finish.

The First part is how to make the charging bay the but starting at 2:25 is the gun in action.
Sorry there aren't shots of it hitting anything because I was shooting at the couch a few feet away so it wouldn't really prove much. With the capacitor it will shoot about 35 feet on 2.5 pumps. The nerf dart shoots the whole length of my hallway and hits pretty hard when it reaches the end. The hall is maybe 50 feet. I haven't shot it outside yet I just made it last night.
I plan on putting canister in the handle so it can hold more air pressure and at some point I will paint this like the cool steam punk or the plasma rifle instructable. Anyway on with the show.


A Nerf Maverick. The other parts (minus the barrel) came in a kit similar to this but it was cheaper. Found at Walmart .
For the barrel I used some pipe I had laying around. I would recommend you get a length of copper piping used for plumbing it works better. And a bike pump/ air compressor/ co2 cartridge with the proper adapters. Thats all you need. *you need a hot glue gun to attach the capacitor to the dart but thats later.

Also, I'm not responsible if you kill, maim, hug, rob, hack, borrow money from, or lick anyone as a result of making this gun. How this would do any of those is beyond me but stranger things have happened.

Hope you enjoy my first instructable.

Step 1: The Charge Bay

There are no step by step pictures with instructions for this but the attached video shows how to do it.
There are a few much more complicated instructables showing how to make this but this is the easiest, least cool looking method.

This is the same video that is on the first page so if you watched that you can skip this one.

1.Take a disposable camera apart.
2. Locate the capacitor.
3. Carefully cut it off leaving equal amounts of wire on the circuit board and capacitor. * I recommend making a mark with a sharpie down the length of one wire to note which side of the capacitor connects to which wire*
4. Take 2 "crimp on butt connectors" (found at radio shack.)
5. Cut off the wider part of the connectors so you are left with the thin center portion with the metal in it.
6. Attach one connector to each cut wire on the circuit board and crimp on.
7. Slightly crimp the other end of the connector so the capacitor can fit in and be removed fairly easily while still making contact.
8. You are done. It sounds harder than it is. I've made one of these in 30 seconds before.

Step 2: Unscrew Everything

1. Unscrew everything. I mean everything, every screw inside and outside of the gun. Remove it all. You only need the shell of the gun. (this would be a good time to paint it too, initially I had plans to make this look like the steam punk gun from another instructable but living in an apartment there isn't really a good place to spray paint.)

Step 3: Start Attaching Stuff.

Picture of Start Attaching Stuff.

2. Basically you just screw things together using teflon tape on all the threads. You will notice one of my hoses is simple 'forced' into a connector, this was for my own safety just incase I over pressurized it the only thing that would happen is the hose would pop off. These parts are rated up to 90 psi. The bike pump started leaking on me from the plunger before I could pop that tube out.

It's very straight forward and rather than bore you anymore I will let the pictures do the talking.
Attach parts as follows:

Step 4: The Dart

Hopefully your glue gun was heating up while you connected everything.

1. Cut a nerf dart just about in half
2. Insert a mcdonalds straw into the dart and trim to fit
3. Put a small drip of glue into one end of the straw. Allow glue to harden
4. Put a drip of glue onto the hardened glue and attach the capacitor. (the reason you do this is so you don't melt the dart or the straw.
5. Charge and shoot.

licking some1 made me crack

super knex dude (author)2010-01-02

 i put it to a piece of aluminum metal and it slightly melted the contact leads of the resistor, so i would think that it would  probably burn someone if they got hit by it. i am going to put this HUGE mother fricking resistor that i got out of a computer monitor on a homemade nerf rocket. it took me a whole minute to charge it.

JackB21 (author)super knex dude2015-06-07

Yeah.......Thats a CAPACITOR. if you fire resistors they won't do a thing.

Cause a resistor is going to do so much on its own...

why don't ypu put 3 in a nerf rocket?
mwaaahaahaahahahahhaahahahahaaah!!! (evil-ish laugh)

XOIIO (author)super knex dude2010-02-22

Don't you mean capacitor?

super knex dude (author)XOIIO2011-04-13

oh yeah right

Dont kill anyone.

boil your head

Sreyo (author)Hades di Angelo2011-04-12

Yea, what does that mean?


justjude97 (author)2013-12-08

hi, i saw this 'safe' instructable while looking for ways of world domination. i was wondering, what the max i could charge the capacitors to without (overly) hurting somebody, maby a playful shock. would this be any danger at all to anyone, probably not since it the travel distance is short but you never know, thanks.

Divergence (author)justjude972015-01-14

No this is not dangerous, the current is not strong enough, you can fully charge it safely. It will give you a hell of a shock though!

jlsajfj (author)Divergence2015-03-18

lol, metal melting with capacitors right on top of this

point blank (author)2009-04-22

Does this actually work, I mean shock people. If so, how bad does it shock people?

Loshanagan (author)point blank2009-10-14

These chargers pack a powerful punch. I once accidently shocked myslefon one. It was not fun. I felt a surge of electricity go through mybody. Of course, these won't be as powerful as real shock guns used by cops

Divergence (author)Loshanagan2015-01-14

That's not even possible you would only feel it where you got shocked because unless you had wires in you tie and head connected to a capacitor

Dracanse (author)Loshanagan2010-01-24

 me to.... i thought some one stabbed me in the back then i realized i touched the leads haha

cld0000 (author)point blank2010-06-02

Depends on the charge level and the voltage rating for the capacitor(s), and how it's wired. If you get the ones out of a camera flash charging module, it would feel like as if you touched a "shocking" gag item.

blackdogg (author)point blank2009-11-20

yea, but lorobo lies, you cant feel it go through your body, there is not enough  space between the wires, your skin gets burned and there will be a small hole with blood, hurts alot!!! not much but its effective on enemys who want to beat you...

Radicaleddd (author)blackdogg2009-11-20

Blackdogg: It does tense up what ever limb it hits pretty good. That might be what he meant. And there will be 2 small holes.

Radicaleddd (author)point blank2009-08-28

Yes it works, it shocks people with whatever the 'payload' of the cap is. In my case about 300v.

mettaurlover (author)point blank2009-08-26

as long as both leads make contact. yes. and it hurt. a LOT.

johnstat000 (author)2014-07-15

Do you think this mod is compatible with any nerf gun?

LolzMan (author)2014-04-30

Unbelievable. Go to some random HvZ game and whip out this one :)

dudes (author)2013-12-05

What if you hooked the cap leads to sewing needles ( evil)

DSJesterXII (author)2013-05-27

This is an abomination. This is a horrible invention. This is... I must build it!

Raptor Z (author)2011-10-19

couldn't you put a small capacitor into the tip of a nerf dart, load it into a modified nerf gun (remove air restrictors to increase the range), and make some form of lighweight contact on the pins.

what i am getting at is, load the Maverick with 6 capacitor tipped darts, charge them all, and then fire them all off in quick succession. (MU HA Ha ha........)

tinker234 (author)2011-06-07

wow rocking concept could i use this to make a ronons gun with there mods of volatge death stun irradcte which would basicly light you on fire

james4 (author)2011-03-26

is that benny goodman? what tune is it?

Great Job :D

I love the music in your video :D

Colonel88 (author)2009-08-28

first of all, i suggest connecting the pump to some container (pvc pipe?) so the air pressure is greater. second, the sharp points on the cap may puncture the skin and then it would not be good, trust me. I sugest putting aluminum foil on the ends of the capacitor so it doesn't pierce the skin.

benduy (author)Colonel882010-11-17

why not just stick it in a nerf dart then shoot someone in the bare skin!!!!

Revan_Taros (author)Colonel882010-11-11

that is the whole point. its a tazer

cld0000 (author)Colonel882010-06-02

or just attach/solder a metal rounded tip to each lead, provided that they aren't too close to each other that it would discharge itself.

Radicaleddd (author)Colonel882009-08-28

I made another version of this that is not in a nerf gun that has a larger canister so I can build more pressure but for the sake of fitting in a nerf gun I omitted that from this model. As far as the sharp points...well that's kinda the point :-p (punny huh). Anyway since the current wont go thru clothing it has to be pointy to piece your targets cloths. I made 'tips' out of coax cable leaving the inner most plastic shield and the copper wire sharpened to a point. This way you slide the coax tips over the capacitor leads and you have a 1. sharper 'dart' and 2. it keeps people from getting shot with something that was just stuck into someone else (I care about my victims :-p) .

teddy1998 (author)2010-06-16

do your darts ever pop? cause theyre just foam. you know the air pressure would blow it up?

mattbomb (author)2010-06-01

 ya untill a bird eats it and become radio active. great idea 

hungyhipo 2 (author)2010-04-16

that would hurt like S*#@

Pumpkin$ (author)2008-09-01

this is why I wear styrofoam in my shoes XD plastic bags work too...

Ian01 (author)Pumpkin$2009-09-01

That won't help you.

Pumpkin$ (author)Ian012009-09-02

Why not, you're not grounded, no current..

Radicaleddd (author)Pumpkin$2009-09-02

This isn't a power line :-p

Speedmite (author)Radicaleddd2010-02-04

No, it isnt, but its high enough voltage to hurt, and it will go from spike to spike.

Ian01 (author)Pumpkin$2009-09-26

It doesn’t need a ground. The current flows directly from one spike to the other.

Radicaleddd (author)Pumpkin$2009-09-02

You like to be shocked with sweaty feet ? :-p

SorryBarry (author)2009-02-25

why would you want to do this

Brother_D (author)SorryBarry2009-03-17

Where is that from?

Ian01 (author)Brother_D2009-09-01

Looks like Penny Arcade.
