Can I Mod A PS2 Controller To Have Rapid Fire?

I Want To Put The Rapid Fire Mod On A Wired Ps2 Controllor Anyone Know How?

Use a 555 timer, this diagram shows how. A 555 timer is a general purpose timing IC and set as shown it gives you a repetitive pulse when triggered. If you like you can add a bypass switch for when you don't want rapid fire.

Here's the complete page i copied that from
