Hi all, does anyone have the schematic diagram of the Namco light gun sensor board? Namely the Namco 96-0454-00 amplified type sensor, trying to find these now is very difficult, and i'd be interested to know exactly what is in there to see how they have done it all. I use the Guncon .45 and the Guncon 2 on my projector and they typically work very well. Some of the other guns for other consoles don't tend to work so well on the projector, and some just won't work well enough to use at all. If i could replicate this amplifying circuit and do a bit of testing i reckon i could get any of them to work without a hitch. Here is a couple short videos of the Guncon 2 in action on the projector: |

I just replace the sensor transistor and the LM311 IC and they are 99 of the time good to go. most of the time the sensor has a broken leg or blown from static from the monitor (make sure your monitors are grounded on gun games) and i just replace the LM311 as a matter of course since it's like an 60 cent part https://www.mouser.ca/ProductDetail/Texas-Instruments/LM311PSR?qs=VBduBm9rCJS3za09gxtBzA%3D%3D the original sensor eye transistors are NLA but a suitable replacement i have been using is the OP805SL its about 5 bucks. https://www.mouser.ca/ProductDetail/Optek-TT-Electronics/OP805SL?qs=MYMjFsmMg9YRusPHjGj65w%3D%3D be sure to cut the correct leg off and orient it correctly. very rarely the L1 Inductor goes open, but that's only if it's had a serious zap. i'm unsure of it's value. so for about 6 bucks in parts, you can rebuild the sensor boards. that goes for IT guns, raw thrills guns... really most of them that use this same optical triggering system. some of the sammy ones use a different sensor, but more or less the same. |

I want to amplifer boost them so i can run a lower drive on the blue tube. Light guns only care about the blue image, green has minimal impact, and red is completely ignored. You can disconnect red and green (or in the case of a projector simply cover the green and red lenses) and the guns will still work perfectly. Cover the blue lens or remove the blue signal input and the gun won't work well, if it will work at all, and it generally will not. Namco used to sell an amplifer boosted sensor board for their guns, part number is in the first thread. If i can find a diagram of that board or get one of them i can replicate it. This board allowed those guns to function well even on very worn tubes with low light output. |

i getcha. you are talking about having these.... and replacing it with this... https://na.suzohapp.com/products/arcade_game_parts/96-0454-00 yes, it's a (now) standard optical drive system used everywhere.. i can draw up a suitable schematic for you if you'd like. it' wont be EXACTLY the same , but will operate the same if you want to take a stab at rolling your own. |

Would be great if you could do that, would appreciate it!! Thanks mate!! :) |
