Hello. I have installed aimtrak in a ps2 gun case: p99 LIGHT gun Logic3 and it works (the motor turns when i shoot to the screen), but the problem is: the engine wheel don't turn enough for move the gun slide. I have try to set in the options coil to the right, but is not enought. Could be modded the program or the firmware for send more than 40ms of pulse? It could be really interesting for person who uses gun case of ps2 with electric motor instead of solenoid. Thanks. |

Nobody? I have sent a mail to andy, but no reply yet... Thanks. |

Hey Mitsurugi, Am just at the start of this hack. Have my two aimtrak modules and my two (cheap :) ) Logic 3's. The gun has so much in - shame to waste the vibration module! How did you wire everything up, especially the recoil function? Thanks Steve |

the aimtrack has a set pulse, i believe the program changed the recoil voltage for aimtracks solidnoid. What you want to do it change how large the pulse is, i believe Andy does not modify his firmwares which is rightfully so, but you could look at programming a small pic chip to that could handle it for you or even a small circuit with a capastior |

I have been looking into this problem and have come up with a circuit that does exactly is needed for P99G2. Essentially, the aimtrak puts out a 5v pulse when the gun is fired at the screen, and the recoil slider bar in the configuration options sets the pulse duration (up to 40ms). However, you need an approximately 200ms pulse driving a motor driver ic at about 7.65V to get gun to recoil properly. In order to get the recoil to work and still have adjustability, I wrote some Arduino code for an ATTiny that measures the aimtrak recoil pulse and adds a static timing offset to the measured pulse duration. This lets you get a pulse that is in adjustment range of 180 to 220ms, and is adjustable through the aimtrak software. I have tried it on a P99G2, and it works pretty good (I also added some code to let the recoil be disabled by the switch on the bottom of the gun). If anyone is interested in the schematics and code I used, let me know. |
