Controller Modding (HELP!)

[elusive-umbreon]

note: I am using the venom controler

I'm nearly finished my first portable I've just encounter a problem though

I don't know how I should go about modding the controller

Originally I wasn't going to mod it but I encounter problems with that as well because I would have to have the controller below the screen but this covers up the trigger buttons.

so the only way I feel I can do this is to mod the controller so the buttons are either side of the screen. I have the following questions (I'm thinking about using the tact switch method). If there are any good tutorials for this could you please point me in the dirrection of them?

If I'm to use tact switches, what do I solder to what?

Would it be possible to maintain the original ABXY buttons and D-Pad buttons (I'm thinking the pad that makes the contact normally would be able to put enough pressure on the button it presses, but I'm not sure. if I have to take some extra step what do I have to do

What value tact switches do I need

Are there better/easier ways if so, explain?

If you can provide diagrams that would be great thnx.

hi

If you want to use tact switch, you'll need stripboard, I'm sorry I'm french I don't know the right word
A small picture to illustrate my point:

You can order stripboard on amazon or ebay

Then you just have to set the tact switch on the stripboard, make welds necessary, and it is good
I do not know where are the relocation points on a venom controller, i'm sorry

Trying to follow the traces

I'm not familiar with strip boards, so please correct me if I'm wrong but does it go like this
I slot the tact switches in the desired position around the board.
I solder wires from the bottom of the strip board to the contacts
Happy days

or is it slightly different to that

as for the contacts is it basically just ground on one side and signal on the other with ground all connected to each other or is it different (What am I looking for exactly?)

also why do people have so much trouble with L and R is it that slidey thing they're pinned to, if so what is that for and is there a way to ditch that system all together and have tact switches?

Thanks for the quick reply

and your English is good (I wish my french was as good as your English lol)

The gamecube has analog triggers, meaning they slidey thing is a potentiometer that with a resistance that varies.
The potentiometer has three points, one to ground, one to 3v3 and one "data". Depending on the resistance, the voltage on the "data" line changes, ie when you slide the potentiometer the voltage on the middle pin varies.

The buttons are easier, this picture is from Kasar's GCp guide! and explains what you are trying to do.

If you don't have strip board you can use a piece of plastic that you drill holes for each button leg. CD cases work great for this.

As for replacing the analog triggers, you can use zenlocs trigger mod. You can find it in the gamecube sticky.

Hope this helps

Hi

I work on my portable cube, i made this for you, an exemple

 

[elusive-umbreon]

Thanks so much, I have another quick question. How do I figure out which wire on the Controller board goes to which connection on the port board?

(if u don't remove the controller board)

I've seen those pictures I'm talking about inside the actual controller itself, I'm using the venom controller so I can't really go by colors. What I'm asking is how am I to tell which wire is which in in the controller.

 

[Multi7200]

I'm sorry I did not understand your question

More precisely what you mean to the poor little French i am

 

[elusive-umbreon]

I'll try to make it clearer

if I were to open up a controller and strip the wire how can I tell which wire is which, since its a third party controller I can't base it on color, do I need the plug bit or is there a way to tell using a multi-meter or something

 

[Multi7200]

Yes you can, with a multimeter, you locate the ground, cable shielding, 5v power line, and 3.43 logic supply (probably), the last is the data line.

 

[Blargaman91]

When you plug the controller into a running GameCube, the data line will also read 3.43v.

 

[watsug]

Connect the controller to the socket of the gamecube. With the gamecube off test continuity between the different coloured wires and the points on the gamecube controller daughterboard. Since the daughterboards pinout is known, you will know which colour is what connection.
If you don't want rumble only ground, 3v3 and data is needed.
