By the way - thank you for posting the VX5 board scans and pics of the modified battery. I'm ashamed to not have contributed board scans for the VX5 when I got my hands on one early.
TAKE A LOOK AT THE JOYSTICKS. Sony returning to the "three leg" potentiometer type joysticks to save money?
You're Welcome, and thanks for posting up that pic.
That thing looks more like a 3rd party controller to me. None of the TP spots have anything in common with any other version of PS3 controller. The way the silkscreen is missing from components, that Reset switch, Analog sticks. The Accelerometer having 2 spots is nothing new, but they've always had it laid out one on each side of the board, not both right next to each other. Curious to see the other side of that board now.
Parts of it seem kind of Sony, but most of it just doesn't look like them at all. If they've decided to go this route with the controllers, then I'd wager they've saved a ton of money on making them, both in parts and the quality of the PCBs.
