Hi Guys, I'm currently working on an Arduino powered light gun for use use on Windows & RetroPie have a look at the demo here. Let us know what ya think, anyone keen to have a crack at building this? I hope to have a build guide up soon. Cheers Sam |

That's really impressive man. We are starting to move away from ir-based systems due to the issues that usually revolve around them, but a diy gun is a really good idea. I look forward to the guide. |

Nice work. I am assuming you are using the DFRobot IR positional camera, that returns positions of the 4 brightest infrared points? One problem I saw with that approach was, that the field of view is pretty narrow ( almost as narrow as the wiimote`s field of view ). The result of your work should be pretty comparable with the aimtrak lightguns, probably even in cost. Don`t get me wrong, I really like it; however when I see an approach I almost have to point out what I think could be problems... :laugh: |

The project as it stands is very similar to a Aimtrak. I just wanted to make a gun that was as plug and play as possible, that people could customise as they need and hopefully improve on as I found out more. I've already found a wiiMote hack that uses 4 iIR leds as opposed to 2 which looks promising. But I think the real main reason is that I'm just nerd and wanted to have a crack at building one these myself :lol |

Yeah, the problem with 4 points is: (or atleast my problem was) I could not solve the Perspective n Point problem for 4 points on an arduino in real-time ( 60 fps) as it involves quite a lot of math. https://en.wikipedia.org/wiki/Perspective-n-Point I haven`t looked into it, but it might be possible to solve it via lookup-tables? could be close to the computational limits of an arduino though. Keep us updated if you manage to implement anything. :) |
