xarcade tankstick button wiring?

Pages: (1/2) > >>

Yuskis1:

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.

PL1:

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

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

BadMouth:

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.

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.
