I don't really have the equipment necessary to run the kind of tests I would need. I am pretty certain that I know how they work after some correspondence with Happ; but as posted earlier, I am not familiar with different IC numbers and can't find what I consider to be sufficient electronics for such a project. I probably wouldn't have enough time to devote to building anything until fall semester is over(assuming I don't take intersession classes). Does anyone know chip numbers for something like a quartz timer IC and sychronous counters and such that would work in the 50-100mhz range? Maybe there is some sort of PIC that could be used instead. But the bottom line is, anything I make would be pretty simple(calibration would be awkward and accuracy would be questionable) at least in the first version. |

Hi! I got a very useful peice of info about XBox guns from another message board. Quoting post: What is the yellow wire used for? Allow me to quote "Hacking the XBox" by Bunnie Huang: "The video sync signal is a 3.3V CMOS or TTL-compatible signal. It is a basic 15.734 kHz positive polarity pulse train synchronized to the horizontal line time of the composite video output, with a single longer pulse at the beginning of every video field. This signal enable peripherals that are pointed at the TV screen, such as a light pen or a light gun for shooting games, to derive position information." What does this mean? A device that as of yet does not exist would use this signal combined with a lens & photodetector to determine where at the screen you are pointing. I doubt that it will ever be utilized at this point, unless the Linux guys write something to use it. from url: http://forums.xbox-scene.com/index.php?showtopic=6134&st=75 Hopefully this helps anyone looking into using an XBox light gun. |

The trick with the Act-Labs guns is to make sure the game size matches the calibration screen size. If that is done properly, the gun will hit almost EXACTLY where you aim it. The only problems I've had at all, regarding accuracy, are driver/software based. On several games, you need to use the mouse to calibrate the cursor on the calibration screen by moving it to (0,0) and (256,256) manually. By contrast, I don't remember ever seeing an arcade gun that shot properly. My experience with arcade guns has been that you always need to use "Kentucky Windage" on them, based on where the previous shot hits the screen. My thought is that most of them needed to be calibrated, and would probably have worked fine, had that been done. My point is that a properly calibrated Act-Labs gun is as accurate as you are going to get. I don't see the point to paying the HUGE money we are talking to interface an arcade gun if ACCURACY is the goal. My only complaint about them is that they are ugly, as compared to arcade guns. I can see someone ELSE spending the money to interface the arcade guns if LOOKS are the goal; but I think you are setting yourselves up for severe disappointment if you think the arcade guns will be any more accurate. |
