after using the thumbstick for about a week i decided to add even more buttons for easier PC navigation while driving.
i had an old 6 switch panel from a broken TV so i decided to solder it to the Xbox controller board.
the first step was to strip the black contact points where the buttons are, and put some solder on them for easy wire attachment (see pic).
i then soldered the wires to the 6 switch board then i cut them and made a plug for them so i can unplug it if i have to take it apart.
the last step was to make the holes for the buttons on the dash and make the illumination for them. here is the result.
afterwads i cconfigured the buttons with JOYTOKEY for my needs, which is; switch joytokey profiles, visualization fullscreen, main menu, navigation, dimm, settings. the 2nd profile makes the thumbstick emulate a mouse and the buttons; switch profile, enter, up, down, backspace, mouse right click.
