Picture of Xbox 360 Rapid Fire Modification
A while ago I was asked by a friend to make a rapid fire modification for his Xbox 360 controller. At first, I was not quite sure how to make one , but I agreed to do it. Like always, the internet is the first place I go to when I don't know something. But after a couple hours of searching, I was unable to settle down on a good reliable way to do the modification, so I improvised and created a circuit that actually turned out to work quite well.

This modification works on a Xbox 360 controller, but it can(should) also work on other kinds of controllers.

The white controller was the controller that I made the modification on but since I have finished the modification already, I will be performing the modification on another(black) controller.

Edit: **There has been a change in parts. Look under Step 1 & 6**

Step 1: Materials

Picture of Materials
HCREVA0002_800-800x600.jpg
perf-boards.jpg
- TLC555 timer
- 100k Ω resistor x 2
- 1M Ω variable resistor
- 0.1 μF capacitor
- 0.01 μF capacitor
- micro momentary switch x 2

- Xbox 360 controller
- circuit board

For the 555 timer, make sure to use TLC555, not NE555. NE555 requires a higher supply voltage(4.5v), while the TLC555 requires much less(2v). Because a regular Xbox 360 controller uses 2 AA batteries (3v), a NE555 timer will not operate properly. 

**Edit**: It seems that the 1M ohm variable resistor is hard to find for most people. If that is the case, here is a new parts list:

- TLC555 timer
- 10k Ω resistor
- 22k Ω resistor
- 100k Ω variable resistor
- 1 μF capacitor
- 0.01 μF capacitor
- micro momentary switch x 2

- Xbox 360 controller
- circuit board

I made but it does not shoot as fast 5 shots a second im sure i got all the right parts but ill see if i can figure it out at first it would just shoot like the regular rt button then it started working but idk what i did wrong i will build another one any help will be greatly appreciated

Can you tell me what king of cap's you use? Like MONOLYTHIC Green, ect too many listings on eBay and hardto match up using pic's thanks :)
heol dylan.ceta1 month ago

You can use ceramics caps.

I orderd 3w 100ohm resistors they looked the same but to big are they 1/4w resistors? Only reason I ask is they are brown
heol dylan.ceta1 month ago

Yes, 1/4W resistor will work just fine and are smaller than 3W (and cheaper)

grant.cox.3114 months ago

I tried this and the controllers worked perfectly...But the TLC555 gets so hot you cant hardly touch it.. Any advice? Ive checked my connections on the bottom side repeatedly and see no problems. Does the wattage of the Caps make a difference?

IMAG0328[1].jpg
What watt resistors did you use .25 .5 1 2? Only thing I can't match
could you make a video on how to do this? I am seriously considering making one

Would it work for the "B" button? How diferent would be the wiring/solders?

ernie666 (author)  Brunissimus8 months ago

yes, you can wire it to do rapid B button pressing. However, the pads of the B button are not as easy to connect with wires. The conductive (black semicircle pads) are not readily available for soldering; their wires have to be traced in order to find solder-able connections. An alternative method is to expose its wires by scraping the protective coating away and connecting wires to those exposed areas.

Tks!!!

:) just finished making this .. came out eh looking but works nice.Made it for COD:Ghosts ! Rockin the auto Snipers !

forgot to say i made it ={

good mod but if you put the momentary switches inside of the controller under the trigger you can just pull the trigger and it will rapid fire also i have made a mod that shoots 2 times for every one trigger pull havent seen it anywhere else works great for controllers that cant get the conventional rapid fire mod message me if you want a tutorial and subscribe for other mods add me on xbox if you want or apply for my clan if you think you can beat me in a private match my gamer tag is chickenstrlp that is an L in strip and there is no caps my clan website is

Would not work untill i ran a wire from pin 2 to N.C. then it worked great!!! Perhaps you forgot a line on the schematic?

ernie666 (author)  Perdurable1 year ago

ahh..no wonder I have so many comments on how it doesn't work. pin 6 and pin 2 are supposed to be directly connected. I will change that as soon as possible. My apologies.

haha no problem man this is a great circut and awesome Tut. It is exactly what i was looking for because it give the trigger a full triggle pull worth of voltage therefore it works on every game! glad we found the problem im happy i helped

It didn't work for me. I have lots of experience soldering and building circuits/ modding game consoles, and nothing works. I'll try some thicker power wire, but I'm skeptical. :(
ernie666 (author)  Basement_Modder1 year ago

I'm sorry to hear that, but I'm not sure how to help. Although there is another modification I have in mind right now; that is to use a PIC microcontroller, which if done correctly will only require the simple hardware stuff (wires, momentary switches) and none of the resistors and capacitors. In fact, if a surface mount SOP-08 package chip were used, it won't even require the removal of any of the motors. Programming a PIC to do these simple turning on and offs is quite easy and effortless. Using a PIC microcontroller is superior in all ways when compared the the method presented in this instructable.

Sorry. My fault. I had a wrong connection for ground. I do agree though. This is a GREAT tutorial. :)

MrBlankiez1 year ago

I just made this... didnt turn out too well. Right now, it just acts as another trigger on the controller. I used all the listed parts but still didnt work. :P What am I doing wrong?

You must have done something wrong (incorrect connections/ wrong parts) Yesterday I`ve made rapid fire from this (GREAT) tutorial, everythink work OK (COD Ghost- pistols, shotguns, marksman rifles)

Would it affect anything if I only use one button? like instead of having a left and right, just having a right?
ernie666 (author)  VHIT17171 year ago

no, not at all.

pjexton1 year ago
This is so cool! It's just like the modified controllers from http://www.ms4r.com/. Having that rapid fire included in the controller makes all the difference.

I actually had no trouble at all finding the 1M Ohm resistor at Radioshack. Link: http://www.radioshack.com/product/index.jsp?productId=2062297
joshmt20122 years ago
do you have the part numbers for all the components?
ernie666 (author)  joshmt20122 years ago
no, but all of the parts listed are available at Radioshack, with the exception of the 1M ohm variable resistor. If you are having problems finding a 1M ohm VR, I have actually come up with a better combination of the resistors and capacitor. Look under Step 6.
LJModz1002 years ago
Is the variable resistor a must or can I use a regular 1 m ome resistor
ernie666 (author)  LJModz1002 years ago
yes, you need the variable resistor to adjust the frequency. You can switch it out with a regular resistor, but you need to find the appropriate value for the desired frequency, which differs between different games.

Would using a 100K variable resistor instead of the 1M variable resistor still work?
ernie666 (author)  alexlobrano2 years ago
The circuit itself would work perfectly fine. What really matters is the controller/game 's ability to respond to the impulses from the circuit. If the frequency of the impulses was set too high, the controller/game will have problems responding to them. With 1M variable resistor, the frequency of the impulses can be adjusted roughly between 6~50Hz, but with a 100k VR in place of the 1M, the range of the frequencies becomes much smaller, about 30~50Hz. In other words, the lowest frequency the impulses could be adjusted if a 100k VR was used instead of the 1M VR would be 30Hz. In most cases 30Hz is way too fast. So if you were to use a 100k VR you would also have change the value of R2 or C1 or perhaps both. Either way a 100k VR will only give the circuit a small range of frequencies, but this could be beneficial in some ways. For example, if you know the approximate frequency that you want, then you could set the circuit at that approximated frequency by changing the values of R2 and C1 and afterwards, use the 100k VR to make the fine adjustments. Because 100k Ω is a much smaller value than 1M Ω, it is easier to make finer adjustments on the kind of 1-turn trimmers.

You can also use a small flat screwdriver. The trick is to wedge it with the outer edges of the blade hitting 2 of the screws flat surfaces while the middle of the blade is against the center post.
inverted torx security bits are available cheap surplus shops will have these
great design

Great idea. My partner is disabled and is unable to repeatedly press buttons. This will be great. Many thanks
