Introduction: DIY Pistol (fps) Mouse

Picture of DIY Pistol (fps) Mouse

This instructable will show you how to build a pistol-grip mouse for first person shooter games.
(note: these instructions were made after the actual device, so the pictures are of the finished product disassembled)

Step 1: Preparation...

Picture of Preparation...

You will need:
1 old joystick (just the handle/trigger thing)
an old optical mouse
soldering iron (you can build it without soldering, but it's not as reliable)
hot glue, duct tape, third hand, molten plastic or whatever to hold it together.

Step 2: Take Them Apart!

Open the joystick handle and identify the wires for each button.
in this case, the trigger wire is red,
the top button is white,
and common is blue.
(common is a wire that connects both, so you only need 3 wires instead of 4)

Step 3: Mod the Mouse

solder or otherwise attach the wires from the joystick to the mouse buttons.
i chose to use the trigger (red wire) for the left button, and the top button (white wire) for right.
find the common terminal by following the circuit traces, there will (should) be one wire/trace going to both (in this case 3) mouse buttons, this is where you will attach the common wire.
On my, and most other mice, the common is the ground. (the negative power source everything connects to)

Step 4: Physically Attatch the Mouse to the Joystick.

this is the most difficult part of the build, and unless you have the exact same mouse and exact same broken joystick, you'll need to be creative and figure this out yourself.
but, If you do happen to have the exact same mouse and joystick you can hammer a pen onto the screw anchor thing, and use the joystick's screws like a vice to clamp the joystick to the pen.

Step 5: Results

After years of using a normal mouse, i've developed a nasty calice on my palm, and after an hour of playing games, my fingers ache like crazy! using the joystick mouse is much more comfortable, and i'm able to aim and shoot faster. It's a little awkward for regular computing tasks, but that's just my opinion. your mileage may vary.

Step 6: Going Further...

I've just added a scrollwheel as a replacement for the top button (the button was old and not working right anyway) it also serves as the right button, i may add the middle button, but not soon, it was hard enough to add the wheel. I will post pictures soon. (but i will NOT show the inside as i probably won't be able to put it back together again without problems, but i will provide ample explaination)

I think a wii nunchuck would be perfect for this....

I'd mod a cheap airsoft gun by taking out the internals and putting in a momentary switch under the trigger, the hammer could be right click, and the scroll wheel would be on the side.

That is one, crazy, awesome watch you got there, how does it work?

The Daft (author)bounty10122009-09-02

ah hahaha... Its the good old binary watch. It tells time using binary. :D

bowmaster (author)The Daft2011-02-09

your watch is on the wrong hand.....

joe57005 (author)Elementix2008-06-12

I'm left-handed.

sora (author)joe570052010-07-04

im left handed...the best , and smartest people are...jk

masterchrisx3 (author)joe570052008-07-02

im right handed and have my watch on my right its what i am used to

joe57005 (author)masterchrisx32008-07-06

i used to have it on my left hand like everyone else, but it kept hitting the desk whenever i write.

Archive555 (author)joe570052008-08-30

Wow, who'd have thought that post would lead to a chain of comments this long?

Elementix (author)Archive5552008-08-30


Archive555 (author)Elementix2008-08-31

Yes, 'lmao'. What is this 'lmao' you speak of, for I doubt it has the meaning of 'laughing my a$$ off', for you would hardly be able to type if it were the case.

CybergothiChe (author)Archive5552009-02-11

that is very true, if he was, as he claims, laughing his a$$ off, then he would have great difficulty typing "lmao" in order to tell us all that he is, in fact, laughing his a$$ off. One thinks that, therefore, he must have been somehow mistaken, and not, as he so strenously claims, laughing his a$$ off. The question is then, if it was not his a$$ that he was laughing off, what was it...?

Archive555 (author)CybergothiChe2009-02-13

Exactly what I'm talking about. I think that he has caught the oh-so-popular 'use memes all the time even when its not appropriate like when my friends dog died I said lol, lol' bug. It happens to the worst of us ;)

techman9 (author)Archive5552010-05-18

 wow we are all super geeks 

Ph3nomin0n (author)Archive5552008-09-12

Wow lol look at all the reasons... I just wear mine for safety precautions... Were im from if your drivers side window is down people take your watch clean off your hand if your not careful, I guess ive grown used to it and putting it on the left just feels wierd... lol but those are valid reasons too...

blakeredfield (author)Ph3nomin0n2009-02-13

I'm counter-dexterous: I always use the opposite hand for the task that I'm most used to using the other hand to achieve said task with.

necropolian (author)joe570052008-10-16

i've cut the bands on my watch off, and i carry it in my pocket. it's really easy, the only bad thing is you can lose it faster.

cormac3050 (author)masterchrisx32008-08-17


tanmanknex (author)cormac30502009-06-28

same, lets see how many we can get.

red-king (author)Elementix2008-10-24

depends on what your dominant hand is usually... or sometimes its just personal preference.

Ph3nomin0n (author)Elementix2008-09-12

I wear my watch on the right and my bracelets on the left... nothing wrong with that Great Instructable Btw

R4Man18 (author)Elementix2008-08-12

This post actually pwns and is funny because its fairly random and it doesnt matter what side you put it on. I keep it right because my left is my secondary so I keep my cell phone, wallet ect on my left while my right is only for cigs.

techman9 (author)2010-05-18

 Dude i have the same watch it's sick right!

Nyanman (author)2008-07-03

it's one of the binary watches right? neat instructable. make a pistol grip for the novint falcon next pls. it needs one badly.

bounty1012 (author)Nyanman2010-03-11

They've already got one, they probably didn't at the time though.

joe57005 (author)2008-06-30

Thanks! that mouse looks pretty awesome too, i need to add leds to mine now!

Nyanman (author)joe570052008-07-03

what next on it? mini flamethrower maybe? you'll never lose a LAN party again with one of those in a mouse. just torch who ever is ahead of you. BWA HA HA HA HA HA HA HA!!!!!

joe57005 (author)Nyanman2008-07-06

no man, LASERS! big frigging lasers!

Nyanman (author)joe570052008-07-06

yea,but lasers are inefficient, expensive, and need big heatsinks or liquid cooing. a lethal laser won't fit on it. maybe a taser?

bounty1012 (author)Nyanman2009-06-29

but tazers are weak...

C18H21NO4 (author)bounty10122010-03-11

Have you ever been tazered? I have. Tazers are not weak =D

bounty1012 (author)C18H21NO42010-03-11

I meant compared to a laser.

eduardoh (author)2010-03-07

Here is a video of my prototype, I am still going to improve it, next thing would be to add a rumble to the gun everytime you shoot.

this is part # 1 of the videos the next one will be with the gun in action.

eduardoh (author)eduardoh2010-03-07

here is the second video, showing how the game works with an actual game.

this is part 2.

Derin (author)2009-12-26

you should cover the whole room with the fps using projectors and turn a 3D mouse into a pistol mouse :D

bounty1012 (author)Derin2010-03-06

Check out the Novint Falcon, its the most awesome thing ever.

eduardoh (author)2010-03-02

I want to make this pistol mouse, i have all the parts but where do I connect the cables on step 3?, this are the pics from my mouse, I have a Gateway MOAKUO MOUSE MOUSE.  Please somebody help, I really want to make this instructable.

eduardoh (author)eduardoh2010-03-04

updated image of the mouse's bottom

deathsmileyinc (author)2010-03-02

sorry, but i dint get the point of this mod, i mean, this is almost the same thing as a normal joystick, so why woulnd you use that??

nobody394 (author)deathsmileyinc2010-03-03

Well I use windows 7 which doesn't support my subsequently useless gameport joystick, also steam seems to have troubles with my usb joysticks so making a joystick that steam thinks is a mouse is golden.

blakeredfield (author)2009-02-13

Should be lower though, I think. So you dont have to raise your hand so high during normal use. I think. I saw a battle-mouse or something, lilke the one you guys have built here. I really like it. Dont have a spare joystick to mess up though. Thinking of alternatives....

Peonpower (author)blakeredfield2009-11-02

You should check out the FPS Gun Mouse instructable, they do it as a gun, but just use these steps instead of the webcam things they do.

tanmanknex (author)2009-06-28

what about, if you do this again, attaching the joystick to the scroll wheel so you can zoom in and out in your game?

Kokkan (author)tanmanknex2009-10-12

That would be nice.

Kokkan (author)2009-10-12

Is it confortable to use?
I want to make one, but I can't find my old joystick :/
