To satisfy a couple of requests, I made this little vid to demonstrate non-destructive removal of the spring from standard gamepad joysticks (Xbox 360, PS3, Logitech, etc.).
If you don’t have a nephew’s games closet to raid, you can always buy the joysticks. This is my source. Tell Uwe I sent you.
Here’s where I show how to wire-them to the CV inputs of a Shruthi-1.
Back and building with vengeance…
