Bluetooth Controller Hack for the Axim x50v

When it comes to to this BT controller hack for your Axim, some people are going ask "why?", While others are going to say "cool!". While I doubt it that I would ever go to the trouble, if you're looking to attach a game controller to your PDA, here's one way to do it:
While not a big console gamer, i am a fan of the way Sony designed their Playstation controllers. With that in mind, i decided to take the innards of the BT gamepad and put them in a modified PS controller. I was extremely lucky in acquiring the controller. i wanted a black one (like the PS2's), but also one with out the analog sticks (PS1 only). Ebay said there was no such thing, so i was prepared to compromise. When i went to the local GameStop, however, two minutes of searching yielded exactly what i wanted--and for only $3!

The wiring was not as easy as i thought. The D-pad was OK with one wire for each button and a common ground, so it wired into the PS controller's board just fine. No such luck with the action buttons, however. While Sony did it the logical way (like the D-pad), the BT gamepad did not have a common ground. WHY?!?!? Well, a bit of dremmeling took care of that and each of the PS's buttons now had 2 wires. I then wired the PS's "L2" and "R2" shoulder buttons up to the BT's "L" and "R", and the "R1" up to the BT's "start" (as the PS's original start button had been removed).
