Thanks @Ginsonic, I'd love to know how ya go! Yeah, I did play around with smoothing a little bit but as I use it for gaming I didn't want to add any latency, and I don't really notice the jerking that much when I'm actually playing (generally play with cross hairs off when I can). However, if you're using this for something else like a dedicated mouse cursor, then yeah, a smoothing script is probably a good idea as currently double clicking an icon is near impossible. I used this library https://github.com/MichaelThessel/arduino-analog-smooth when I was when I was mucking around with it. |

I usually take a bunch of analog values in a loop (about 5-10) and then divide the total by the count of measures. Mostly simple and effective, but I will see, as soon as I have finished my MPU6050 based XInput Lightcannon project (similar to a Deadstorm Pirates control panel including a steering wheel ;) ) http://www.ifunpark.com/wap/eacp_view.php?id=81 |

This looks great. Have you given any more thought to using the 4 leds discussed above? If it increased accuracy above what you typically get from guns like the Aimtrak then it would be even better. |
| samco:
Yeah, I'm still looking into a 4 LED option but I'm actually pretty happy with the accuracy now. Good timing really I've just uploaded a video which demonstrates it pretty well... Still looking into the 4 LED version thou because as it will shorten the distance you have to be away from the screen (current version is about 2.5 screen widths) and possibly even reduce latency. |
| lightgungamer:
Hey, That looks great. How does it cope if you move position? Thats always the shortfall with the aimtraks etc. If you shift a little way from where you calibrated the gun then the accuracy goes way off so I was just wondering how well it handles that? |
