Hi Forum Folke,
I’m trying to source a 3-leg, pc-mount potentiometer used in many game controllers. They are standard analog pots, not digital. I’m having an awful issue with the pots in my xbox 360 controller; the response curve is just impossible to use with any accuracy. My feeling is that an audio-taper pot was used where a linear taper pot SHOULD have been used. I’d like to source the manufacturer of this pot so I can see if there are different tapers available, and if so, buy a couple of linear tapered pots of the same ohm value and solder 'em in to see if that fixes the problem.
I’ve had the thing apart, and there are two of them (x-axis and y-axis) per each joystick. They are mechanically fastened into a sheet-metal frame 90 degrees from each other, and without unsoldering the assembly from the board and completely tearing it down, the only visible markings on the pots are “B103 3810” on the face of the pot opposite the input shaft.
My fear is that the manufacturer buys these things by the carload in an OEM configuration, without any data printed on the part to identify it. Many pics of these things do not show any silkscreened information, and of the ones that do, most of then have the “B103 3810” visible on them (I have seen one other number, same format, same “B” prefix, but only that one… the vast majority are of the 3810 kind.)
Any ideas or leads to pursue or maybe somebody actually already knows this (somebody knows, somewhere, that’s for sure… hope there’s one here!)
Thanks for reading!
