Seems easy, but! My knowledge on electronics are… teoretical (Polish school system, goddamn stellar). I am pretty good with soldering, but just the simple one (like HRAP3 PCB, you have signal and ground, pretty much straightforward).
My problem lies here: what to do with pins 7, 8 and 9? Which one is the ground (any of them?). I don’t know what to do with those three pins. Any help?
Also - my solder iron is pretty big (tip is more than 1mm), is it too much for those little pins? I had some problems with it, not very big, but still, got pretty irritated now and then.
Pin 7 is actually a film resistor on the green membrane that connects to the header there.
Pin 8 is the ground line for the buttons and joystick
Pin 9 is the ground line for the start/select/analog button
Using that pad is no good for an Hrap3 since the HRAP is a common ground board while this one is a common line board. If you can find a DS1, it will be a lot better than the DS2
to take the words from slagcoin where the diagram came from
“You can cut the tip off the membrane when using a PS1 model, but you may need the membrane if you are using a PS2 or PS3 model. The PS2 model has two more paths than the PS1 model; one path is a ground specific to the start, select, and analog buttons; the other path is for a resistor; the PS3 has another resistor and two more paths. The PS2 or PS3 controller will engage most the buttons when it does not have the resistor(s) and ground in the membrane attached at the appropriate terminal slots; either the membrane or a 1K to 10K resistor for PS2, or 7.5K to 8.5K for PS3 (cannot use the membrane on the PS3 PCB when doing solderless), wrapped (staggered) around the bordering wires must be installed with the wires to function. You may need to angle the membrane and wires so they make proper contact, so the added resistor will work much better.”
That seems like a problem, since PS1 pads are either expensive or in very poor condition these days. So, basically, using this pad won’t do it (without doing some hardcore crazy modding)?
Here in Poland it isn’t that simple. I was pretty lucky to get that DS2 cheap (~$7). Old DualShocks are around 10-15 bucks Also, when I was saying “poor condition”, I meant either damaged PCB or something like ripped/cutted of cord.
Also, please note that I am not doing dual mod - just a PS2 stick Would that make my pad more useful?
Sorry for the secound post in a row, but I’m going home soon, and I’d like to know - simple and straight - would simple soldering wires (using two “grounds”, like mr.mortified said) be enought to make it work?
How feasible is it to shop around until you find a really cheap PS1 pad (any model)?
Those are usually much much easier to add into mods.
Not sure how you could damage the PCB other than blunt force.
Ripped/cut cord can be fixed easy.
Well, today is my 8th day since I started to look for any old psx pad. Unfortunately, in my town there aren’t any shops where I could buy stuff like that, so only private users (from boards, auctions etc) comes into play.
The analog buttons (X, Square, Circle, Triangle, R1, R2, L1, L2, Up Left, Down, and Right) are in red text in the link you provided. Therefore, they use the red ground (pin 8.) The buttons in blue are digital, and use a separate ground, which is pin 9. Pin 7 is for a resistor, which should be 4700 Ohms. One end of the resistor should go to pin 7, and the other end should go to pin 8.If you don’t have your own 4.7K resistor, you’ll have to buy one. (Alternatively, you could just keep the thin sheet of plastic plugged in to the socket, if you haven’t already removed the socket.
