555 timers cannot be programmed as they are not blank chips...

555 is fine for rapid fire you just hav to set it up right, i have a schematic for it, all you need to do is build it on some vector board or vero board and youre set

heres the shematic:

im not sure of the resistors but everything else is good, find a power source on the board to leach from, then attach the outputs to were the fire connects to [not sure]

will the 555 rig in that tutorial work for both wireless and wired controllers?, and will it work on both older and newer style boards?

the tut you want to use is this one https://www.acidmods.com/forum/index.php?topic=25338.0

and yes it will work with both controllers


this thread should be locked. there is no usefull info left, the tut for this on xbox scene has all its pictures missing. and that diagram above is incomplete. please let this thread die.
