Introduction: Simple Xbox 360 Rapid Fire Mod

Picture of Simple Xbox 360 Rapid Fire Mod

I'm sure you've seen what a modded controller can do if you have played online on games such as Call Of Duty, Halo, Counter Strike or Battlefield.

Here's a really simple modification to enable you to shoot your Barret 50 cal like a P90.

UPDATE: There seems to a problem with certain controllers. There are Matrix controllers that use PWM for the LEDs and some which use a different method. To determine the type of yours, remove the battery pack of your controller. Above the right battery terminal, if there is a " TP-19" then it is matrix controller and it will work with this mod. If there isn't a "TP-19" than it is the newer CG version and it will not work.

Step 1: Ingredients

Picture of Ingredients

First off you will need,

A TT8 Torx Driver
Small Push Button Switch
Some Thin Wire, Any will do (I used IDE Cable)
An Xbox 360 Controller (Wired or Wireless, it works the same)
Soldering Iron
A Drill and Drill bit (To match the diameter of the thread on your switch)
Some form of surface to work on. (I used a window ledge, I suggest you don't)

Step 2: Dismantle

Taking the battery out reveals another screw, its underneath the barcode sticker.

There's 7 screws Torx screws to remove

With the buttons facing DOWN, separate the two halves carefully, paying attention to the motors.

Step 3: Drill

Picture of Drill

Find the best place to put your switch. Choose very carefully cos once you've drilled you cant remove the hole from your £30 controller!

Once you have found a place, put the two halves back together and double check there is enough room for your switch to go in.

If there is, remove the circuit board so that it doesn't get damaged and drill away.

Step 4: Switchin

Put the switch in your new hole. Make sure that you orient the pins so that they are not getting bent or squashed when the controller is back together. I had to remove some of the motor holder to fit my switch in.

Step 5: Soldering Time

Picture of Soldering Time

Heat up the soldering iron, not too hot or else it might break some components.

Point one and two are in pictures 2 and 3 respectively.
An final overview is in picture 4.
5 and 6 show the switch.
7 shows what happens when your iron is too hot and you take too long to make a joint.

Make sure wiring runs stay clear of the black button pads, analogue stick movement and screw holes.

Step 6: Put It All Back

Picture of Put It All Back

Are the switch pins going to make contact with anything on the other half of the controller when reassembled?

Are all of the wires free from places of movement or screw holes?

Are the solder joints correct and not dry?

Are all of the annoying black pieces of the controller back on their positioning pins?

Has your soldering iron made suitably sized black marks on your window ledge?

Four out of five is good enough to continue.

For a quick test, replace the battery and depress your switch all the way. If the player one led lights up very dimly, then the mod worked!

Now try putting it back together without breaking anything.

Step 7: Done!

Picture of Done!

If you are having trouble putting it all back together, try wigging it while applying gentle force, and make sure all wires and button rubbers are not obstructing anything.

Here it is in action!

Step 8: How It Works

This works because to light the LEDs (on some boards with the crystal described in the intro), the Xbox uses Pulse Width Modulation (PWM), which sends the power to the LEDs in quick pulses. This mod uses them pulses to trick the Xbox into thinking you are pressing the trigger really quickly.

So which one ?

conorh135 (author)2015-07-02

Hey guys quick question do you solder the live wire or the power wire to the led ? Or both ? Need to know asap

wavylays (author)2015-06-28

does this work on rock candy controllers?

AlonzoCarsenaz13 (author)2015-06-10

My controller has TP-19 and TP-20 idk what to do. On the TP-19 the T is a little covered HELP ME!

CyeBorg99 (author)2015-05-14

Thanks for the instructions, worked perfectly!

avlachos (author)2012-07-07

Did everything step by step mbut i have a number of problems the push button doesnt fire when activated plus if i hold it down and use RT nothing happans as if it cancels the firing system. Last the player 1 LED doesnt appear dimmly rather not at all.. Any HELP would be VERY awsome ASAP..

maltak (author)avlachos2012-07-22

Yea this exact thing happened to me. the player 1 led fell off and the right trigger doesn't work. 

zachary.giles.96 (author)maltak2014-12-27

***update*** this does still work!! Cod bo2! But I got the wrong button so i have to hold the button in order to use the right trigger! And maltalk don't know if ur still in here but the reson ur trigger is not working is either it's the same problem as mine or u just have solder or wire touching another point

Could it work with the "B" button? How to do it?

imma.boss.7967 (author)2014-10-11

I did everything right but my switch is activating by its self I have to hold it so it will not fire please help

Diablllo. (author)imma.boss.79672014-10-21

lol i just posted a comment about that hopefully it will help you

ShortbusX (author)2011-04-20

IMO it really is simpler to solder the second wire to the right rumble pin. I couldn't get my mod to work with the led soldering spot, but the rumble pin worked like a charm :O

BrandonSnow (author)ShortbusX2014-10-13

What do you mean rumble pin?

Diablllo. (author)BrandonSnow2014-10-21

the rumble pin is the motor which vibrates the controller there is an negative and positive wire

Diablllo. (author)2014-10-21

idk who still sees this page but me personally used these steps back in 2008 to mod my controller and figured out that i was using the wrong push button the button shown in the pic is an normally open push button meaning when you solder one point the led the negative side and the other wire the motor what happens it will keep shooting until you hold the button

so i switched the button to an EVQ-PB with the four pin and solder the two wire to each of the corners and it worked fine

while the LED as an NEGATIVE and a POSITIVE side make sure to use an resistor on the led for it not to burn out if its to hard to solder the wire just find another negative point on the controller

using the right wire Gauge is important to

alecreiter (author)2014-09-29

I didnt get it right

AndrezBandera (author)2014-02-20

Here's the thing, I would like to add a new button to my original Xbox S-Controller (the old Xbox), I would like to add an extra left trigger, I noticed that it has 3 pins insted of the regular 2 pins, I went ahead and tested and it showed me that the two conducting when I pressed the trigger were the two on top... So I installed my two pin button with those two pins in the controller, leaving the extra pin free, the lower one. I use that button to fire in Halo 2, so I went to test my controller and when the game starts It works, but then I use the originall left trigger the new button stops working... What can I do to fix this problem? Has it to do with the extra free pin? Or do you think it is a problem directly of the button? I recycled it from an old TV.

Thank you in advance, have a nice day.

LetTheBassDrop (author)2012-11-30

I did everything exactly as listed, i have the controller with the silver resistor in the middle and all that happened is when i press RT nothing happens unless i hold down the switch. like when i dont it cuts the circuit.

CasperWade (author)2012-11-18

The LEDs are hard to solder and have a strong joint. Is there any other points you can solder this to?

redneck2023 (author)2011-09-28

I know this is an old post but i was wondering if anyone could help me... i did everything right and the trigger still works but the rapidfire button acts as a secondaey trigger and not rapid at all... what did i do wrong? it worked perfect before i soldered everything down

Ultrachris96 (author)redneck20232012-11-02

Is it an older controller? because if its a new one it wont work trust me i found out the hard way

sroethler (author)2012-09-05

where did you get that push button?

erodicsponge (author)2012-08-31

you guys aren't missing out on anything. rapid fire mod only makes it so that you don't have to keep slamming down the trigger to fire. it doesn't add anything.

I have had problems with the soldering portion of this project. I have tried two seperate times to solder ( one on a matrix board one on a CG board). I cannot get The negative terminal of D21 (or D1 on the CG board) to solder to my wire. I ended up pulling the LED out with my wire both times. Is there any trick to this? Am I applying too much heat?

I am using a nexxtech 45W soldering iron.

Thanks in advance.

lol you melted your controller in pic 7

cdombach (author)2012-05-09

TheRealNuge (author)2012-02-26

Hey guys Ineed your help. What do you solder the wire to when you solder the wire by D21? All I have is a LED Light. Is that what I Solder it to?

pogoman12345 (author)2011-07-24

ok so the torx screws in the controller shown r different than the ones in mine. mine r the security screws with a pin in the middle. anyone know where i can get a security screwdriver small enough?

rcgigessss (author)pogoman123452012-02-07

you can find it in every hardware store and there its saiyng that its T8 but I have a T9 which is perfest 4 all the screws u want 2 untighten in xbox and accessories

davidt123 (author)pogoman123452011-12-26

I just got a set of those security screw drill bits from my local hardware store. I had to grind the bit on the sides a little though to allow it to unscrew the screws in the bottom tips of the controller

Acko619 (author)pogoman123452011-10-01

I used a small flat head screwdriver and chipped the little pin away, you canalso buy torx screwdrivers that have a hollow tip that are designed for those screws. hope that helps.

pogoman12345 (author)Acko6192011-10-02

thank you and yes it does help

grantanthonywalsh (author)2012-01-06

right i want to do this mod it seems very simple, however i cant find them red tactile buttons, i tried ebay ans stuff but no luck. website please? and also define any cable, red, black? thin, fat??? thanks

Xbox Modz (author)2012-01-01

I have the "other style" controller, and ive already drilled the whole and added the push button. If i solder and finish the process will i be able to use both trigger buttons? (the standard and added) I know the rapid fire wont work but using two triggers would be nice.

red fox (author)2012-01-01

how big does the switch have to be

davidt123 (author)2011-12-26

Can I use my controller if it doesnt have the crystal or whatever you call it in the middle of the circuit board, if not where do I get a controller like that?

bsmith50 (author)2011-07-23

does it matter how thick your wires are? i plan on modding my controller soon have some thinner wires want to make sure they will work

Thicker is fine if you don't short anything out thinner's just easier to work with in this case.

This wire in this instructable is really easy to get if you've got any old computer's or old computer parts lying around you can take the Gray IDE ribbon cables apart and use that.

MACKattacksnipe (author)2011-08-17

could you use a common ground instead of the LED? or is it backwards you need the led for the 3.3V in power source

omnibot (author)MACKattacksnipe2011-11-09

A regular 555 in astable mode should work nicely if you don't have pwm LEDs on your controller.

You need the LED+ for the 3.3 power also this Mod will ONLY work with that LED ie... If you soldered to the player 1 LED you must be Player 1 for it to work this mod uses Pulsed Modulation also instead of using that BIG OL' push button get some 5mm Tact Switches they fit almost anywhere. Hope this helps

btop (author)DaddyDeadLegg2011-11-09

In all the others controllers I modded I used tactile switches, theyre a lot easier to use and you're left with more room to work with inside the controller.

DaddyDeadLegg (author)btop2011-11-09

Just a Quick Tip to those who haven't used a Tact Switch before "Super Glue" is too thin to fasten it to anything use Hot Glue or some other Thicker Epoxy..

ztaffa (author)2011-07-07

hey umm is there an alternative to soldering, can i use hot glue?
