Thanks for the reply Vigo So take one of the two main wires and spilt it between the two small circles on the big circles? How could I find out if it has a common ground? I can take more pics if needed. Like I said, me and wires do not go hand and hand ;D Ugh why can't this be easy haha |

Yes, it has a common ground. Notice how one of the circles has a line going away from it, and the other one doesn't? The one with the line is the signal, and the other is the ground. |

Yeah, it's never easy. Thinking optimistically, it's always educational. :) --- Quote from: sandman235 on August 19, 2011, 04:45:06 pm ---So take on of the two main wires and spilt it between the two small circles on the big circles? --- End quote --- I think you got it, but let me just clarify to make sure. So if you take 2 wires, lets just say green and purple for example, solder the green wire to the left mickey mouse ear of a circle, and the purple wire to the right ear of that same circle. Then take the green and purple wires and hook them up to the switch. I drew on your pictures as a visual: |

Thanks guys that helps so much. I will give it a go tomorrow. Thanks again. |

It looks like the ground plane on that controller is pretty big. If you want a bigger target, you could scrape some of the laminate (green stuff that makes the pcb green) around that test point to essentially make the pad larger. Solderability will be different than on the gold pad, but it should work. If you do this, make sure you ONLY do it with the GND side, since the signal line has a very thin trace. After reading this I realize how much jargon is in this post. If you get it, feel free to try it. Otherwise just go with what these other guys said ;) EDIT: !#%$^ wife says I'm typing too loud. Later I'll come back and elaborate. |
