Hi there, I’m working on building a joystick from scratch, but hitting the limits of my mechanical know how. One of the reasons I’m doing this is because pretty much every joystick you can buy, not to mention instructions for DIY joysticks, have springs that return the joystick to the center. I would like to make one isn’t auto-centering (maybe with a bit of pressure at the middle) but rather has more or less constant friction and stays where you put it.
When I 3d print the gimbals I could just glue something on there so that it doesn’t move very smoothly, but I wonder if there’s some mechanism or component I could search for that would be a better solution. What do you call something that’s the size of a spring but instead has two pieces sliding over one another to create friction?
I was going to follow a design using magnets and hall effect sensors rather than pots. I’m not sure whether a very stiff pot would make this easier; and how to stiffen it up so to speak?
