Sorry for not taking pictures of the "inside job"... Didn't had a good camera at my disposal at that particular time
So what does it feature... ? Mostly practical "fixes" for the most annoying traits of the 360 Controller.
* Mini USB Connector (because I was annoyed by always needing to wrap that "tethering system" and pay attention to it when I was going to disassemble the Controller)
* Convex Right Analog Thumbstick Cap (because Right Stick falls closer under my thumb making aiming much more comfortable with a "domed" shaped Thumbstick Cap)
* Better Analog Sticks (recovered from a Logitech Rumblepad 2. The ones with the metallic mechanism and yellow potentiometers. Those have less physical Deadzone and are softer)
* PlayStation D-Pad (specifically a combination of PS1 and PS2 D-Pad parts for the best result. PS1 silicone contact pad and cross support, PS2 Cross and black case)
EDIT1: So... after all I did took a picture while I was working on it, but... sadly, it's not really on a professional level of quality
It's more like a blurry mess...
EDIT2: Here are some pics of the specific Analog Sticks model:
The only difference is that the ones recovered from the Logitech GamePad have longer metal rods where the Thumb Cap gets attached.
And it's better because most Analog Sticks already have longer protruding holes after the Thumb Cap rod end level stops, making the Thumb Cap fasten more securely on these Sticks.
What I did was filling the wider Thumb Caps rod holes with standard 360 Thumb Stick plastic rods cut at the necessary level and I was left with tight holes to fit perfectly on the "new" Thumb Sticks.
Btw, I would be really interested to know if anyone still produces these and where to buy them.
