noob question, kind of...

[Gengurru]

Okay, here it goes.

I have to do a school project on electronics and my teacher said he was open to ideas. I recently bought Marvel vs Capcom 2 for the original Xbox and i don't have have an arcade pad, so i figured i'd mod a regular Xbox controller and turn it into an arcade pad for my project, killing two birds with one stone. i took a controller apart so my teacher could look at it and he said," find the ohmage(real word?) for the potentiometer on the joystick." i scoured the internet and could not find a schematic or wiring diagram anywhere.

Does anyone know the ohmage for an original Xbox controller analog stick?
Didn't think so.
Does anyone have any suggestions for turning an original Xbox controller into an arcade pad?
Yes i have searched the forums and wiki and for a minute i thought i had a guide but alas, a dead link.

Finally, i would like to thank you for reading and apologize for the wall of text.

It doesn't matter, since you'll need to wire your stick to the d-pad rather than the joystick.  Don't you have an ohmmeter in this electronics class?

I believe xbox & 360 are both 10K

as stated before me use the D-pad and buttons and they work like a +/- pretty much for the signals so no multimeter is needed just solder and wire

your teacher should know that you cannot take a analog pot and connect it to a digital arcade stick and make it analog unless your using a analog joystick wich are costly for a school project but then again he may not have the slightist clue on how a basic arcade stick works.

 analog is not really needed for a arcade stick setup anyhow as most games you expect to play just would not feel the same playing them in analog when your use to digital like in the arcade's or any other 3rd party arcade stick that is mass produced..

Oh. Well thanks, that makes things much easier.

Something else just occurred to me, is it possible to wire the triggers to be buttons?

Yes

Because of the recent announcement of Marvel vs Capcom 2 for Xbox Live and the plethorra of guides, I have decided to just make one out of a 360 controller.

Thanks for all your help!

Sorry for the double post, but i figured it would be better than starting a new thread.

I have thought of many more questions. After looking at HarumaN's guide for hacking a 360 controller, which is very helpful, I realized may not be able to do it, but i cant have HarumaN do one for me because I'm turning this whole process into a school project. So is there an easier way to do it or is that the only way. Also after looking at HarumaN's guide i realized that it ends after you put the wires in the terminal strips, and being the noob that i am, I have no idea what to do after that and all the guides that I find on the internet either don't work or suck. So if you guys could instruct me or guide me to a good guide, that would be splendid.

the buttons and joysticks have cherry switchs Google search to define more.

a button has one switch

the joystick has 4 switch

each switch has a +/- to be simple

when the button or joystick is pressed it makes the +/- toach and short if you will wich causes the signal to be sent to the pcb for the button you pushed or joystick movement.

so you would put a +/- wire to the buttone or joysticks cherry switch and then plug them wire into the controller signals wire that you want the button or joystick to work as.

if you use a common ground controller you can connect all the grounds on the buttons and joys all together on one common ground wire instead of making seperate grounds for each and every switch.

thiat way you have your + signal going to the pcb part that you want it to mimmic and all grounds tied together om the buttons and joys with only one wire running to the pcb for ground.

if you use a matrix controller that is not a common ground then you would need seperate +/- for each and every button wich in the end is twice the work for the same result as if it were a common ground.

I know you want to do it with a 360 controller BUT you could use one of those 'build it yourself' PS3 board  make up a nice box and a good portfolio and you should be fine.

i did this http://forum.arcadecontrols.com/index.php?topic=75805.0 for GCSE.... sure it certainly isn't the best ! and i didn't have a clue what i was doing but an entire year on now and the machine still works..however some little  has damaged my coin mech.

hope you get something sorted out

I'm just gonna follow HarumaN's tutorial and use an Xacto knife to scrape away the protective layer thingy then take it from there.

Thanks for all the help.
