How To Make A Turbo Button
I put an Xbox 360 controller board in my X-Arcade Solo stick a while back to have a proper arcade stick for Xbox Live Arcade games and fighting games. The Xbox 360 controller I have has a turbo button on it but I have been thinking about adding a faster one.
If you are interested in adding the turbo button to anything, here is the parts list (all of this can be found at Radio Shack) and the schematics:
- Circuit Board (optional)
- R1 = 1K Ohm Resistor
- R2 = 10k Ohm - 100K Ohm Resistor or Variable Resistor (The lower the resistor, the faster the pulse) Start with 47k and go from there.
- C1 = .1 uF Capacitor
- 555 Timer

If you attempt this, make sure you get multiple resistors between 10k Ohms and 100k Ohms (or a variable reistor) in order to find the best pulse rate for your turbo button. I used a 22k Ohm resistor, which is about 30 button presses a second. You don’t want it to be so fast that it just registers as one long button press and you don’t want it too slow.
Note: If you are interested in converting your X-Arcade stick into an Xbox 360 stick, I used an Xbox 360 MicroCon Game Pad Pro [Gameshark or Madcatz] and 30 gauge wire. The hardest part of this mod is mounting it to the board. I used two big screws going through some tubes to keep the board raised above the buttons (See pics above). This thing is a must have for any old school gamers and arcade junkies. Some games just don’t feel right on a gamepad.

I’m trying to figure out what contact points to use for example if I want to make A turbo. I used http://forums.xbox-scene.com/index.php?showtopic=466559. I hooked up the + and - and touched the 3 wire to point 1 for the A button from the site above it would rapid fire but it also seemed to be a common? and would cause a left thumbstick up?
Any feedback on how to make this work properly?
Thanks

You will have to use a relay or an opto-isolator on anything that is not common with the ground on the turbo button.

I have a quick question, where are the points for the Right and Left triggers? How would I go about creating a turbo button for those functions? I got the parts you listed, but I’m too much of a noob to know what to do with them. Please help me and thanks in advance!!

There is handy guide over at Xbox-Scene that shows all the points on the official controller.
