***Radio Shack does not have it. Wire a 1k, 330, and 470 ohm to make one *You can find all of these in the resistor 500 pack, Radio Shack number 271-312A
If you want this to work on the 360 wireless controller, you need to use a CMOS 555 timer(runs on 1.5 volts up to 16 volts, regular 555 takes a higher voltage).
Some things you need to know about the electronic components used in this tutorial, if you don’t know them already.
555 Timer - It has eight pins, and must be put in properly to work. It is a very useful component and is used in many electronic projects. It can be damaged by heat, but it would need to be alot of heat. For more info on it, visit this link
Resistors – They have no polarity so it doesnt matter if you put them in backwards or forward. They cant be damaged by heat.
Transistors – There are two kinds of them, NPN and PNP. We will be using NPN and PNP. They can be damaged by heat. There are three different case styles so that means that their pins may be different in each style of case.
Capacitors – Cant be damaged by heat. Electrolytic(one kind we are using) has a polarity so if they are put in backwards, they wont work properly. The positive and negative leads are usually marked somewhere on the body. I am going to use a Tantalum for one of the two capacitors needed. Tantalum capacitors also have a polatiry and the positive leg is marked on the body.
Diodes - Diodes are used for letting current flow only one way. They have also have a polarity so they wont work unless installed properly.
Variable Resistor(potentiometer, or trimmer) - It can adjust the resistance in a certain range, depending on the one that you use. It can go by three names, variable resistor, potentiometer, or trimmer. A trimmer is the style that I am going to use.
Note: The symbols that I have in the picture below are not 100% accurate to the schematic

For ease of understanding I will use an alphanumeric labeling system when referring to holes on the breadboard. Ignore the holes on the perimeter of the breadboard. Ignoring them, you should see two rows on the breadboard. Each row is three holes by ten holes. Lay the breadboard on your work surface with the trace side facing down and the rows going vertical, so you see one row on the left and one row on the right. Take a writing utensil and mark the top left dot. That dot will be A1. The dot to the right of that will be B1, to the right of that, C1, and so on. Each column will be a letter and each row will be a number, so the bottom right dot will be F10.
1. Solder the TLC555 timer into the breadboard with pin 1 of the chip in hole C4. Make sure that when you solder the timer onto the board you are soldering it with the chip, as well as all other components/wires, on the side of the board that doesn’t have the traces. It should be common sense, but I like to make sure I cover the simple mistakes, as those are the ones that really get people most the time.
2. Solder a wire connecting pins B4 and B3. I used a black wire, for ground.
3. Solder a wire connecting C3 and D3. Again, I used a black wire for ground.
4. Solder a wire connecting B5 and E6. I used an white wire in the picture.
5. Solder a wire connecting B7 and E4. I used a red wire, for power.
6. Solder a four inch long wire to E5. I used another white wire in the picture. I also have the NPN transistor on the board in the picture. You can leave that off for now, that was just a mistake I made while taking pictures. The transistor will get put on in the next step.
7. Solder the NPN transistor into F1, F2 and F3. NOTE: The transistor has to go in a certain way. If you look at the back of the package that it came in you should see a diagram showing which pins are the base, emitter and collector. The collector should be soldered into F1, the base into F2 and the emitter into F3. If you threw away the case, then hopefully you got the one listed in the “parts required” list above. If so, then the “round” side of the transistor should be facing the away from the center of the board, as shown in the picture.
8. Solder another four inch long wire to F6. I used a white wire in the picture.
9. Solder the 100pF capacitor into E3 and E7.
continued...
10. Solder the 220 ohm resistor into C2 and D2.
11. Solder the 1.8K ohm resistor into C1 and D1. Look closely and you’ll see that I’d accidentally soldered an 18k ohm instead of a 1.8k ohm. =P
12. Solder the 10K ohm resistor into F4 and F5.
13. Look at your 1uF capacitor. It should have a very small “plus” sign on it. That is the positive side. Solder the 1uF capacitor into A4 and A5, the positive side going into A4.
14. Solder a four inch long wire to B2. I used a green, for trigger.
15. Solder a four inch long wire to B1. Again, I used green, for trigger.
16. Solder a four inch long wire to A3. I used black, for ground.
17. Solder a four inch long wire to B6. I used green, for trigger.
18. Solder a seven inch long wire to A7. I used red, for power.
19. Flip the circuit board over and use a sharpie to draw a square around the holes of the board that you used. This will be your guide for when you are cutting the board down to size to fit inside the controller.
20. Your finished right trigger circuit board should look like this…
That completes the right trigger portion of the rapid fire mod’s circuit board.
Installing the right trigger circuit board
1. Solder the wire from B2 of the circuit board to one of the leads of the right pushbutton
2. Solder the wire from A6 of the circuit board to the other lead of the right pushbutton.
3. Solder the wire from E5 of the circuit board to one of the leads of the potentiometer.
4. Solder the wire from F6 of the circuit board to the remaining lead of the potentiometer. You should now have two wires soldered to the potentiometer, one on each side of it, not two wires on both sides. Remember, I instructed you to cut one of the two leads that are on one side of the potentiometer in Step 7 of Installing the pushbuttons and potentiometer. Your project should now loook something like this:
5. Solder the wire from A7 to the Power point of the controller’s circuit board.
6. Solder the wire from B3 to the Ground point of the right trigger of the controller’s circuit board. In my picture it is the point with the black wire soldered to it on the right hand side of the controller.
7. Solder the wire from B1 to the Trigger point of the right trigger of the controller’s circuit board. In the picture in step 6 above, it is the point with the green wire soldered to it on the right side of the controller’s circuit board, just below the black one mentioned in step 5. NOTE: If you are only doing the right trigger portion of this mod, you may now put your controller back together. If all went well, you now have a rapid fire button for your right trigger. Adjust the potentiometer as necessary while testing in game to find the setting you desire.
7. Solder the NPN transistor into F1, F2 and F3. NOTE: The transistor has to go in a certain way. If you look at the back of the package that it came in you should see a diagram showing which pins are the base, emitter and collector. The collector should be soldered into F1, the base into F2 and the emitter into F3. If you threw away the case, then hopefully you got the one listed in the “parts required” list above. If so, then the “round” side of the transistor should be facing the away from the center of the board, as shown in the picture.

It still worked for me for some reason, being soldered wrong, but if you want to do it right, follow these written instructions instead.

8. Solder the wire from B6 to one of the leads of the left pushbutton. In the picture below you can see the wire coming across from the right hand side of the controller to the pushbutton shown. That is the wire I am referring to for this step. NOTE: If you are only doing the right trigger portion of this mod, you may skip this step.
