A friend of mine is an engineering student he asked me to post this message on his behalf:
I’m looking for the operation and interfacing of inductive joysticks. I would like to know how they work, what’s needed to interface with a digital i/o port in a computer. What parts are needed? op-amps, resistors, etc. A schematic would be real nice. Any knowledge about their workings would help.
He’d appreciate any online/offline material you can point him to.
He never asks me for help with this kind of stuff so I’m assuming he’s already exhausted all of his usual resources.

I am not sure what you mean by “inductive”. AFAIK standard analog MIDI/Gameport joysticks just use a couple of variable resistors.

Reply from engineering student:
Conventional joysticks are resistive, but industry and “heavy use” applications use inductive joysticks with no contacting parts. Varying resistors have contact, and hence friction, and are prone to fail after long use. Inductive joysticks use some kinda inductor and coil setup… not really sure Looking for info
Armed with this extra bit of information I was able to find the following link for him:

I don’t think he needs much more. Maybe a couple slightly more technical links.
Sorry, I should have asked him about this stuff before posting.
You know what? I don’t think I’m doing his dirty work anymore, if he wants Dopers to help him he can get his own damned account
