is anyone out there familiar with potentiometers and how to tell their strength and compatibility with others? .... namely the ones from the 360 and various joysticks.

all potentiometers work with each other thats why you can take a 3rd party n64 controller and change the analog sticks

Not true. some have different vallues. the ones in the joysticks just have that value since it's well the best value for that purpose I guess.

Pots are really just like a spring with a metal tab on it that turns to correspond to a certain length of set spring,

[]
00000000000000000
zero ohms set value of ohms

by making the adjustment you can "dial in" a new resistance

the reason they have three tabs is because the middle one is the input and the other is the output (usually) the other tabs is just what you what it to do when it turns up or down, variation on the rule exist but just soldering one wire to the middle and another to the other side allows for the pot to become a variable resistor

yea actually joystick are two pots placed together in 2 axes

one controls the x axis and the iother controls the y axis

by setting a standard (middle value) and perversions positive or negative of that value are recorded in the respective direction and there you go a 2 axis joystick!

o sorry i was just thinking of video games i often forget they serve other purpouses

actually do they?

Aren't the pots in joysticks and stuff just used as voltage dividers? If that's true for all joysticks (it is for the one on afrotechmods.com), then they're all compatible with each other's controllers.

Not all vdeo game joysticks are the same either!

Xbox pot up/down: Down:15R Middle:30R Up:45R
GC pot: up/down: Down:0R Middle: 15R Up: 30R

would i be able to replace an existing one in a joystick with a larger one or does it need to be one of similar value? ... btw im kinda new at all this and am just learning the terminology and such. which is kinda funny considering the project i have started.

Erm, they aren't all the same for "video games" through out either.

The way you can tell the value of a pot is by cranking it to it's highest setting and measuring the resistance.
