XBOX 360 analog controller hack... could use some help from you all
(1/4) > >>
Bender:
What I want to build is a dual analog joystick CP for the XBOX360  (maybe the PS3 also down the road)

I've been wanting to do this for a while and don't have enough electrical knowledge to figure it out myself and was hoping with the wealth of knowledge on this forum we should be able to put our heads together and figure it out

because of a chip inside the x360 controller a panel must be built off a hacked original X360 controller

HarumaN has hacked every imaginable input on that controller except the analog sticks (though he said he would be willing to work on it)

the controller has 2 potentiometers that have a range of 0 to 1.61v
the analog joysticks I've seen have 5k or 100k pots, I don't know how those relate
so basically I want to hack a regular joystick to the inputs of the x360 controller's pots

so if any of that makes sense and you have any input I'd much appreciate it


found this on the interwebs

Part 1
Part 2

man, if that guy can build a tilt controller we should be able to add couple of analog sticks


HaRuMaN:
You need the resistance value of the pots from the controller.  Neutral (centered) resistance for both pots.  Then you would need to find the value for 100% North, South, East, and West.

The voltage doesn't mean anything in this case.  You need ohms.
Bender:
I think I can do that with an ohms meter, but how does that relate to 5k or 100k pots?

That's the issue.  You would some how have to modify your analog sticks to match the pots on the controller. 

(5k or 100k pots referring to ohms).
HaRuMaN:
A quickie explanation that I hope makes sense:

I don't know the values of resistance on the controller pots, I'm making these up illustrate my point:

Considering the pot that controls N / S.  Say South is a resistance of 20 ohms.  Neutral is 40 ohms.  North is 60 ohms.  Somehow you would have to make your analog joystick read the same exact resistances for the same exact positions.
