: This is something I've been looking forward to... a cheap lightgun solution. I'm not sure how I can help, but I offer my services in making this a reality. I could write a little test program for you to see if you can get it to register a "hit" maybe. : : : Hi, : : I have done some test with a NES Zapper Light Gun tonight here are the preliminary results: : : 1. here is the Pinout for NES gamepads: : : <pre> : : +----------> (purple) : : | +-------> (blue) : : | | +----> Power + 5V (white) : : | | | : : 5 +---------+ 7 : : | x x o \ : : | o o o o | : : 4 +------------+ 1 : : | | | | : : | | | +-> Ground (brown) : : | | +----> Clock (NC) : : | +-------> Latch (NC) : : +----------> Data (NC) : : </pre> : : NC -> Not connected... : : : : The Zapper have a white wire to Pin 7 (+5V), : : a brown wire to the Pin 1 (Ground), a blue wire that correspond to the Collector of a transistor (Pin 6), a purple wire (Pin 5). : : When I test with a multimeter one the +5V and black wire of the multimeter on the blue wire, the power drop from +5v to 4.5V each time I point the gun to a TV and trigger the switch on the gun... : : I have tried to cover the gun or point it to a light but the result seem to be achieved only when the gun is pointed to a TV! : : I have a friend that have an oscilloscope so my goal is to test it out before Christmas... : : 2. I have scanned both sided of the pcb board of the Zapper... : : see at this URL: : : http://server36.hypermart.net/regisma/zapper_bottom.jpg : : http://server36.hypermart.net/regisma/zapper_top.jpg : : Note the IC no is: Sharp IR 3T07A : : let me kow please if some one make a discovery... : : thanks : : Reg
