This is my first post and - propably - a duplicate or something like that, but - I am really frustrated with this. I have a PS2 DualShock (PCB: http://www.slagcoin.com/joystick/pcb_diagrams/ps2_diagram1.jpg) and I want to use it with HRAP3.
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.
