Out of pure bordum yesterday I decided to do a 555 timer RF mod in my wired mad cats Xbox controller. I also did a led pulse mod as well. Everything works fine when I get off work I'll update this post with some pics. This is a mod I've wanted to do for some time now. I have a old RF chip in it hazers rapid fire 4 mode From years back. Surprisingly the 555 timer ref isent that bad. I tested it on newer games and it works great. I'll get those pics in maybe later today.
