Arcade Stick Episode 6 - It works!
September 18th, 2008
After pulling apart a spare Sixaxis I spent hours soldering and was amazed to find it worked first time!
Check the piccies:
As you can see the mess needs tidying inside the controller but at 2am I was just too excited to have it working so just shoved the guts in like a medic on a battlefield 
I also need to work out a better way to charge it than having to unscrew the perspex base (and have guts fall out) to connect the USB cable to the PCB.
I have some spare mini-usb sockets if you want to hijack one of those and hack an existing USB cable onto it?
Hey I am attempting a similar mod.
Did you have to use the three different “common lines” for each group of buttons?
Like for example, in the pin-out diagram I saw, L2, L1, UP, LEFT, DOWN, RIGHT, all use their own “common” for the ground, that is separate from the other buttons commons.
I guess I am just wondering if i can link all the buttons to the ground, or if they have to be on their specific common line.
I wondered the same thing but just opted to put them in the specific groupings just in case. Good luck
