I hope you fare better than I did.  I tried to help on a PS3 controller modification (tying into the lines) and because all of the buttons are analog and connected to a flex circuit which is just pressed onto the board (no connector) it was absolutely miserable.  We tried soldering to the pads on the board, then it made a finicky connection instead, I tried attaching a wire to the flex circuit thinking that it was copper like similar circuits, and the ink came off, it was just terrible.

My suggestion, get a PS3 compatible USB controller and hack that, all digital, you can move switches around, hopefully no nasty sony flex board in it, etc.

Nice work, Caleb. Can't imagine where you find that "free time" stuff to be able to do this, but glad you can!

I've got one of those here to play with. I should compare the outputs to see how similar they are. That might be my best solution.

That would be a much better layout I think. I'm a bit concernd about attempting to extend this flexible material though. I'm not sure how well I could connect to it, or how long those connections would last.

Another idea is to use force sensing resistors insted of the force sensetive buttons.
that way he would not neet much force

example:

i think that way will be dificult to reach the buttons
would be great to have them near the cursor and on the other side near triangle, etc..

take a look at this image:

i never open my controllers so i don't know if is possible to put a pressure button there
