| xarcade tankstick button wiring? |

I have an arcade tankstick and I am getting ready to build my arcade cabinet soon. Im so excited! while planning it out i have come up with an idea to add extra buttons to the machine for "pause" and "exit" currently to pause you have to push the 2 trigger buttons together. To exit, you have to push player one and the left trigger buttons together. Would their be a problem to just run a second set of wires to each of the 2 buttons and link them to one button so that when pressed it would actually be like pushing the 2 buttons simultaneously? i don't want to risk shorting anything out so i thought i would ask first. I hope this makes sense what i am asking. Thanks for the help. |

If you want to press 1 button (button C) to ground 2 inputs (buttons A and B) at the same time, there are two ways to do it. 1. Wire buttons A and B "backward" like "Up", "Down", and "P1 U+D" in this diagram: - Encoder input connected to COM (buttons A and B) - Ground connected to NO (buttons A and B) - Connect the NC from buttons A and B to one side of switch C ("P1 U+D") and ground to the other. 2. Use diodes like this diagram: If connected without the diodes, pressing either the top or bottom button will complete both circuits. With the diodes: - Pressing the top button completes the top circuit - Pressing the bottom button completes the bottom circuit - Pressing the center button forward biases both diodes and completes both circuits NOTE: The one thing that could make this difficult is that the XArcade encoder uses a different ground for each connector IIRC. Not sure if the "two trigger" buttons you describe use the same ground. :dunno Scott |

You might run into issues if you decide to employ all the external console adapters. |

The Tankstick has one unused lead from the trackball harness that will post as the middle mouse button. I ran that to a dedicated exit button. Just remap the cancel button to the middle mouse in MAME. For other emulators, I have an autohotkey script run at bootup that posts ESC when the middle mouse button is pressed. --- Code: ---mbutton::esc --- End code --- |

Thanks for the feedback so far guys. ill have to experiment with it and see how it all works out. from what I'm hearing though is that i don't have to worry about things getting shorted out or burning up on the button controller then. am i correct? that is my biggest fear since i have heavily modified the whole thing. |
